    More Recalls On GM's Plate


    • Recalls? Recalls. 2.7 Million Vehicles Involved.


    Another week, another set of recalls from General Motors. The company announced today that it's recalling a total of 2.7 million in five different recall campaigns that cover eight different models.

    Here are the recalls:

    • A total of 2.4 million vehicles that include the 2004-2012 Chevrolet Malibu, 2004-2007 Chevrolet Malibu Maxx, 2005-2010 Pontiac G6, and 2007-2010 Saturn Aura for a faulty control module. The module could cause tail lights to either not turn turn on when the brakes are applied or turn on all by themselves. Other items such as the cruise control, traction control, stability control, and panic braking assist may be affected.
    • 111,889 Chevrolet Corvettes from the 2005-2007 model years are being recalled due to the loss of low-beam headlights because of a fail due to a bent wire. 2008-2013 Corvettes appear to have this same problem, but are not part of the safety recall. They'll get an extended warranty.
    • 140,067 Chevrolet Malibus from the 2014 model year and equipped with the 2.5L four-cylinder are being recalled due to the hydraulic brake booster failing and causing a driver to put more pressure on the brake pedal to stop the vehicle.
    • 19,225 Cadillac CTS from the 2013-2014 model year where the wiper motor could break if the vehicle is being jumpstarted and there is ice or snow on the windshield.
    • 477 Chevrolet Silverado and GMC Sierra from the 2014 model year, and the Chevrolet Tahoe from the 2015 model year for a manufacturing defect that could cause the front tie rod and steering gear to fail, leading to a crash. Owners are being ask to have their vehicles towed in.

    “Customer safety is at the heart of how GM designs and produces vehicles, and these announcements are examples of two ways we are putting that into practice,” said Jeff Boyer, vice president of GM Global Vehicle Safety. “We have redoubled our efforts to expedite and resolve current reviews in process and also have identified and analyzed recent vehicle issues which require action. These are examples of our focus to surface issues quickly and promptly take necessary actions in the best interest of our customers.”

    GM Announces Five Safety Recalls

    2014-05-15

    DETROIT – General Motors said Thursday it has informed the National Highway Traffic Safety Administration of five safety recalls covering about 2.7 million vehicles in the United States. The recalls cover:

    - 2,440,524 previous generation passenger cars for taillamp malfunctions

    - 111,889 previous generation Chevrolet Corvettes for loss of low-beam head lamps

    - 140,067 Chevrolet Malibus from the 2014 model year for hydraulic brake booster malfunctions

    19,225 Cadillac CTS 2013-2014 models for windshield wiper failures

    - 477 full-size trucks from the 2014 and 2015 model years for a tie-rod defect that can lead to a crash

    "Customer safety is at the heart of how GM designs and produces vehicles, and these announcements are examples of two ways we are putting that into practice," said Jeff Boyer, vice president of GM Global Vehicle Safety.

    "We have redoubled our efforts to expedite and resolve current reviews in process and also have identified and analyzed recent vehicle issues which require action. These are examples of our focus to surface issues quickly and promptly take necessary actions in the best interest of our customers."

    The largest recall involves 2004-2012 Chevrolet Malibu, 2004-2007 Chevrolet Malibu Maxx, 2005-2010 Pontiac G6 and 2007-2010 Saturn Auras model cars in U.S. to modify the brake lamp wiring harness.

    Affected vehicles could have corrosion develop in the wiring harness for the body control module due to micro-vibration. The condition could result in brake lamps failing to illuminate when the brakes are applied or brake lamps illuminating when the brakes are not engaged. Additionally, cruise control, traction control, electronic stability control and panic braking assist operation could be disabled.

    GM is aware of several hundred complaints, 13 crashes and two injuries but no fatalities as a result of the condition. The company issued a technical service bulletin in 2008 and conducted a safety campaign for a small population of 2005 model year vehicles in January 2009.

    The second safety recall covers 111,889 Chevrolet Corvettes from the 2005-2007 model years for potential loss of low-beam headlamp operation Models from 2008-2013 will be covered under a Customer Satisfaction Program. All repairs will be at no cost to customers.

    When the engine is warm, the underhood electrical center housing could expand, causing the headlamp low-beam relay control circuit wire to bend slightly. After the wire is repeatedly bent, it can fracture and separate. When this occurs, the low-beam headlamps will not illuminate. As the housing cools and contracts, the low-beam headlamp function may return. This condition does not affect the high-beam headlamps, marker lamps, turn signals, daytime running lamps or fog lamps. Loss of low beam headlamps when they are required could reduce the driver's visibility, increasing the risk of a crash.

    GM is aware of several hundred complaints as result of the condition but no crashes, injuries or fatalities.

    The third recall covers 140,067 Chevrolet Malibus from the 2014 model year with 2.5L engines and stop/start technology. These vehicles are subject to the disabling of hydraulic brake boost that can require greater pedal efforts and extended stopping distances. Dealers will reprogram the electronic brake control module. The issue was discovered in testing of a future model with similar technology. GM is aware of four crashes but it is not clear that these are related to the condition. No injuries are known from those crashes.

    The fourth recall covers 19,225 Cadillac CTS from the 2013-2014 model year for a condition in which the windshield wiper system may become inoperable after a vehicle jump start with wipers active and restricted, such as by ice and snow. Potential lack of visibility could increase the risk of a crash. Dealers will replace the front wiper module free of charge. GM is unaware of any crashes or injuries due to the condition.

    The fifth recall involves certain 2014 Chevrolet Silverado and GMC Sierra light duty pickups and 2015 model year Chevrolet Tahoe SUVs. The tie rod threaded attachment to the steering gear rack in these vehicles may not be tightened to specification. With this condition, the tie rod can separate from the steering rack and a crash could occur without prior warning. Customers are being contacted and told to have their vehicles taken by flatbed to their dealer, where the inner tie rods will be inspected for correct torque, and, if necessary, the steering gear will be replaced. The repair procedure was being sent to dealers and owner letters sent by overnight mail to customers on May 14. The issue was discovered and corrected during assembly after the small number of vehicles was released.

    GM expects to take a charge of up to approximately $200 million in the second quarter, primarily for the cost of recall-related repairs announced in the quarter.

    I don't see Ford recalling 15 million cars.

    Hard to recall stuff that is 10-15 years, they already have the bugs worked out and a recall for their less than workable sync system does not affect safety.

    Oddly enough, you almost never see VW/Audi recall stuff.

    That is why we do not see their bleeding edge performance auto's or anything of any real excitement here. They only import what has been fixed and works from Europe. Poor Europeans have to deal with the recalls.

    You do not see much of our recalled stuff over seas. Once they work out the bugs on the American public then they take it over seas and you have strong followers as they never see all the mistakes. Japan and Korea does this also. Test new stuff on the local public before exporting it to sell elsewhere.

    The lambdas are in the recall, those are current, and the 2015 Silverado is in the recall group too. I think certain ATS models were also. It is pretty wide sweeping, so you wonder if they have really addressed the issues, or are they just focusing on the 2004-2010 stuff now, and will be doing another round next year on 2011-2014 cars.

    FTFY.

    I don't think the problem is GM so much as the increasing complexity of cars and the current legal and social climate. Seems that 16 year old girl who was killed in her Cobalt was both Drunk 9obviously underage) and way over the speed limit as well. We have moved away from personal responsibility to blame the corporate guy.

    Although it pains me to agree with Balthazar as much as it does to agree with Regfootball...sometimes Balthy has the right mindset on these things.

      Over the weekend, General Motors published and then deleted the power figures for the new 6.6L Duramax Diesel V8 that would be appearing in the 2017 Chevrolet Silverado HD and GMC Sierra HD. Today at the Texas State Fair, GM revealed everything about this new engine.
      We'll begin with the most important detail, power output. The numbers that GM revealed match the numbers posted to their powertrain site - 445 horsepower and 910 pound-feet of torque. Compared to the current Duramax V8, the new engine produces 48 more horsepower and 145 more pound-feet of torque.
      How was GM able to pull this off? They basically went through the engine with a fine tooth comb and made various changes. GM says 90 percent of this engine has been changed. Some of the changes include new electronically controlled, variable-vane turbocharger, revised cylinder heads, improved cooling, and revised fuel delivery system. The updated Duramax can also run B20 bio-diesel.
      Figures for payload and towing will be announced at a later date.

      DALLAS — Chevrolet today announced the redesigned Duramax 6.6L V-8 turbo-diesel offered on the 2017 Silverado HD. This next-generation redesign offers more horsepower and torque than ever — an SAE-certified 445 horsepower (332 kW) and 910 lb.-ft. (1,234 Nm) — to enable easier, more confident hauling and trailering.
      Along with a 19 percent increase in max torque over the current Duramax 6.6L, the redesigned turbo-diesel’s performance is quieter and smoother, for greater refinement. In fact, engine noise at idle is reduced 38 percent.
      “With nearly 2 million sold over the past 15 years, customers have forged a bond with the Duramax diesel based on trust and capability,” said Dan Nicholson, vice president, Global Propulsion Systems. “The new Duramax takes those traits to higher levels.”
      The new Duramax 6.6L shares essentially only the bore and stroke dimensions of the current engine and incorporates a new, GM-developed control system. The Duramax’s signature low-rpm torque production hasn’t changed and still offers 90 percent of peak torque at a low 1,550 rpm and sustains it through 2,850 rpm.
      “Nearly everything about the Duramax is new, designed to produce more torque at lower rpm and more confidence when trailering or hauling,” said Gary Arvan, chief engineer. “You’ll also notice the refinement improvements the moment you start the engine, and appreciate them as you cruise quietly down the highway — with or without a trailer.”
      Additional highlights include:
      New, stronger cylinder block and cylinder heads New, stronger rotating and reciprocating assembly Increased oil- and coolant-flow capacity New EGR system with single cooler and integrated bypass New electrically actuated/electronically controlled turbocharging system All-new advanced solenoid fuel system All-new electronic controls New full-length damped steel oil pan that contributes to quietness New rocker cover/fuel system acoustical treatments B20 bio-diesel compatibility SAE-certified 445 net horsepower (332 kW) at 2,800 rpm SAE-certified 910 net lb.-ft. of torque (1,234 Nm) at 1,600 rpm A new, patent-pending vehicle air intake system — distinguished on the Silverado HD by a bold hood scoop — drives cool, dry air into the engine for sustained performance and cooler engine temperatures during difficult conditions, such as trailering on steep grades. Cooler air helps the engine run better under load, especially in conditions where engine and transmission temperatures can rise quickly. That allows the Duramax to maintain more power and vehicle speed when trailering in the toughest conditions.
      The intake design is another example of the advanced integration included in the 2017 Silverado HD that makes it over-the-road capable.   
      A strong foundation
      As with previous versions, the new Duramax block features a strong cast-iron foundation known for its durability, with induction-hardened cylinder walls and five nodular iron main bearings. It retains the same 4.05-inch (103mm) and 3.89-inch (99mm) bore and stroke dimensions as the current engine, retaining the Duramax’s familiar 6.6L (403 cu.-in./6,599 cc) displacement.
      A deep-skirt design and four-bolt, cross-bolted main caps help ensure the block’s strength and enable more accurate location of the rotating assembly. A die-cast aluminum lower crankcase also strengthens the engine block and serves as the lower engine cover, while reducing its overall weight.
      The new engine block incorporates larger-diameter crankshaft connecting rod journals than the current engine, enabling the placement of a stronger crankshaft and increased bearing area to handle higher cylinder loads.
      An enhanced oiling circuit, with higher flow capacity and a dedicated feed for the turbocharger, provides increased pressure at the turbo and faster oil delivery. Larger piston-cooling oil jets at the bottom of the cylinder bores spray up to twice the amount of engine oil into oil galleries under the crown of the pistons, contributing to lower engine temperature and greater durability.
      A new, two-piece oil pan contributes to the new Duramax’s quieter operation. It consists of a laminated steel oil pan with an upper aluminum section. The aluminum section provides strength-enhancing rigidity for the engine, but a pan made entirely of aluminum would radiate more noise, so the laminated steel lower section is added to dampen noise and vibration.
      There’s also an integrated oil cooler with 50 percent greater capacity than the current engine’s, ensuring more consistent temperatures at higher engine loads.
      Segment firsts
      Re-melt piston bowl rim Venturi Jet Drain Oil Separator Closed-loop glow plug temperature control Stronger pistons with remelt
      A tough, forged micro-alloy steel crankshaft anchors the new Duramax’s stronger rotating assembly. Cut-then-rolled journal fillets contribute to its durability by strengthening the junction where the journals — the round sections on which the bearings slide — meet the webs that separate the main and rod journals.
      The connecting rods are stronger, too, and incorporate a new 45-degree split-angle design to allow the larger-diameter rod bearings to pass through the cylinder bores during engine assembly. They’re forged and sintered with a durable powdered metal alloy, with a fractured-cap design enabling more precise cap-to-rod fitment. 
      A new, stronger cast-aluminum piston design tops off the rotating assembly. It features a taller crown area and a remelted combustion bowl rim for greater strength. Remelting is an additional manufacturing process for aluminum pistons in which the bowl rim area is reheated after casting and pre-machining, creating a much finer and more consistent metal grain structure that greatly enhances thermal fatigue properties.
      Additionally, the Duramax’s pistons don’t use pin bushings, reducing reciprocating weight to help the engine rev quicker and respond faster to throttle changes.
      Lightweight cylinder heads, solenoid injectors
      The redesigned engine retains the Duramax’s signature first-in-class aluminum cylinder head design, with six head bolts per cylinder and four valves per cylinder. The aluminum construction helps reduce the engine’s overall weight, while the six-bolt design provides exceptional head-clamping strength — a must in a high-compression, turbocharged application.
      A new aluminum head casting uses a new double-layer water core design that separates and arranges water cores in layers to create a stiffer head structure with more precise coolant flow control. The heads’ airflow passages are also heavily revised to enhance airflow, contributing to the engine’s increased horsepower and torque.
      The Duramax employs a common-rail direct injection fuel system with new high-capability solenoid-type injectors. High fuel pressure of 29,000 psi (2,000 bar) promotes excellent fuel atomization for a cleaner burn that promotes reduced particulate emissions. The new injectors also support up to seven fuel delivery events per combustion event, contributing to lower noise, greater efficiency and lower emissions. Technology advancements enable less-complex solenoid injectors to deliver comparable performance to piezo-type injectors.
      Electronically controlled, variable-geometry turbocharging system
      A new electronically controlled, variable-vane turbocharger advances the Duramax’s legacy of variable-geometry boosting. Compared to the current engine, the system produces higher maximum boost pressure — 28 psi (195 kPa) — to help the engine make more power, and revisions to enhance the capability of the exhaust-brake system.
      Along with a new camshaft profile and improved cylinder head design, the Duramax’s new variable-vane turbocharger enables the engine to deliver more power with lower exhaust emissions. It uses a more advanced variable-vane mechanism, allowing a 104-degree F (40 C) increase in exhaust temperature capability. The self-contained mechanism decouples movement from the turbine housing, allowing operation at higher temperature. That enables the engine to achieve higher power at lower cylinder pressure. Additionally, it has lower internal leakage, allowing more exhaust energy to be captured during exhaust braking.
      The integrated exhaust brake system makes towing less stressful by creating added backpressure in the exhaust, resulting in negative torque during deceleration and downhill driving, enhancing driver control and prolonging brake pad life.
      Venturi Jet Drain Oil Separator
      A new Venturi Jet Drain Oil Separator employed with the Duramax 6.6L is the first of its type in the segment and is designed to ensure oil control in sustained full-load operation. The totally sealed system collects the fine mist of oil entrained in the blow-by gas and uses a small portion of the boosted air generated by the turbocharger to pump the collected oil back to the engine oil sump for re-use by the engine. Less sophisticated systems are not able to return this oil during full-load operation, which can result in oil carryover into the cylinders during combustion.
      Cold Start System
      The new Duramax also provides outstanding cold-weather performance, with microprocessor-controlled glow plugs capable of gas-engine-like starting performance in fewer than 3 seconds in temperatures as low as -20 degrees F (-29 C) without a block heater. The system is enhanced with ceramic glow plugs and automatic temperature compensation — a first-in-class feature providing improved robustness and capability. The automatic temperature compensation assesses and adjusts the current to each glow plug for every use, providing optimal temperature for cold start performance and durability.     
      Electronic throttle valve and cooled EGR
      Unlike a gasoline engine, a diesel engine doesn’t necessarily require a throttle control system. The Duramax 6.6L employs an electronic throttle valve to regulate intake manifold pressure in order to increase exhaust gas recirculation (EGR) rates. It also contributes to smoother engine shutdown.
      Additionally, a cooled exhaust gas recirculation (EGR) system enhances performance and helps reduce emissions by diverting some of the engine-out exhaust gas and mixing it back into the fresh intake air stream, which is fed through the cylinder head for combustion. This lowers combustion temperatures, improving emissions performance by reducing NOx formation.
      The exhaust is cooled in a unique heat exchanger before it’s fed into the intake stream through a patented EGR mixing device, further improving emissions and performance capability. An integrated bypass allows non-cooled exhaust gas to be fed back into the system to help the engine more quickly achieve optimal operating temperature when cold.
      B20 Biodiesel Capability
      The new Duramax 6.6L is capable of running on B20 biodiesel, a fuel composed of 20 percent biodiesel and 80 percent conventional diesel. B20 helps lower carbon dioxide emissions and lessens dependence on petroleum. It is a domestically produced, renewable fuel made primarily of plant matter — mostly soybean oil.
      Manufacturing
      The new Duramax 6.6L turbo-diesel engine is produced with locally and globally sourced parts at the DMAX Ltd. (GM’s joint venture with Isuzu) manufacturing facility in Moraine, Ohio.
      Allison 1000 Automatic Transmission
      The proven Allison 1000 six-speed automatic transmission is matched with the new Duramax 6.6L. A number of refinements have been made to accommodate the engine’s higher torque capacity, including a new torque converter.
      The Allison 1000’s technologically advanced control features, such as driver shift control with manual shift feature and a patented elevated idle mode cab warm-up feature, haven’t changed. Also, the Tow/Haul mode reduces shift cycling for better control and improved cooling when towing or hauling heavy loads.
      There’s also a smart diesel exhaust brake feature that enhances control when descending steep grades.

      The new Duramax also provides outstanding cold-weather performance, with microprocessor-controlled glow plugs capable of gas-engine-like starting performance in fewer than 3 seconds in temperatures as low as -20 degrees F (-29 C) without a block heater. The system is enhanced with ceramic glow plugs and automatic temperature compensation — a first-in-class feature providing improved robustness and capability. The automatic temperature compensation assesses and adjusts the current to each glow plug for every use, providing optimal temperature for cold start performance and durability.     
      Electronic throttle valve and cooled EGR
      Unlike a gasoline engine, a diesel engine doesn’t necessarily require a throttle control system. The Duramax 6.6L employs an electronic throttle valve to regulate intake manifold pressure in order to increase exhaust gas recirculation (EGR) rates. It also contributes to smoother engine shutdown.
      Additionally, a cooled exhaust gas recirculation (EGR) system enhances performance and helps reduce emissions by diverting some of the engine-out exhaust gas and mixing it back into the fresh intake air stream, which is fed through the cylinder head for combustion. This lowers combustion temperatures, improving emissions performance by reducing NOx formation.
      The exhaust is cooled in a unique heat exchanger before it’s fed into the intake stream through a patented EGR mixing device, further improving emissions and performance capability. An integrated bypass allows non-cooled exhaust gas to be fed back into the system to help the engine more quickly achieve optimal operating temperature when cold.
      B20 Biodiesel Capability
      The new Duramax 6.6L is capable of running on B20 biodiesel, a fuel composed of 20 percent biodiesel and 80 percent conventional diesel. B20 helps lower carbon dioxide emissions and lessens dependence on petroleum. It is a domestically produced, renewable fuel made primarily of plant matter — mostly soybean oil.
      Manufacturing
      The new Duramax 6.6L turbo-diesel engine is produced with locally and globally sourced parts at the DMAX Ltd. (GM’s joint venture with Isuzu) manufacturing facility in Moraine, Ohio.
      Allison 1000 Automatic Transmission
      The proven Allison 1000 six-speed automatic transmission is matched with the new Duramax 6.6L. A number of refinements have been made to accommodate the engine’s higher torque capacity, including a new torque converter.
      The Allison 1000’s technologically advanced control features, such as driver shift control with manual shift feature and a patented elevated idle mode cab warm-up feature, haven’t changed. Also, the Tow/Haul mode reduces shift cycling for better control and improved cooling when towing or hauling heavy loads.
      There’s also a smart diesel exhaust brake feature that enhances control when descending steep grades.

      The seemingly never-ending diesel heavy-duty truck war is back in force with Ford announcing the power figures for the F-Series Super Duty back in the summer. We were wondering when either FCA or GM would strike back. Well GM did this over the weekend by accidently and then subsequently deleting the figures for the next-generation Duramax V8 diesel.
      Truck Trend got screenshots of GM Powertrain's website where the details of the L5P 6.6L Duramax turbodiesel are there to see: 445 horsepower and 910 pound-feet of torque. Compared the 6.7L PowerStoke V8 found in the 2017 F-Series Super Duty, the updated Duramax produces 5 more horsepower but is slight behind in torque (15 down from the PowerStroke's 925 pound-feet).
      We know for sure that the new Duramax will debut a new air intake system (you can see the new hood scoop in the picture above). More air is a good thing as it means better cooling and more power.
      The Texas State Fair is this week and it has become a showplace for the various truck manufacturers to make big announcements. We wouldn't be shocked if General Motors debuts the new Duramax there.

      The tentative agreement between General Motors and Canadian union Unifor has a $400 million investment going to Oshawa for a new product. Unifor President Jerry Dias said at a press briefing yesterday morning that Oshawa would be the only GM plant that will build cars and trucks. Neither side is saying what that product might be.
      But Canadian newspaper The Globe and Mail has learned from sources that Oshawa will be handling the final assembly of the Chevrolet Silverado and GMC Sierra. Truck bodies from GM's Fort Wayne Assembly in Indiana will travel to Oshawa to have interiors installed and final assembly. The Detroit News reports something similar, although their source says it will only be the Silverado.
      Oshawa has a history of building pickups. For four decades, Oshawa was one of the places where GM built the Silverado and Sierra. But in 2009, GM closed the truck plant due to the recession. 
      The Globe and Mail also reports that production of the XTS has been extended at Oshawa. Analysts believed previously that XTS production would end in 2019.
