2010 Cadillac SRX Recalled for Possible Engine Failure

Published May 26, 2010

Just the Facts:

GM is recalling 547 2010 Cadillac SRX vehicles equipped with the turbocharged 2.8-liter V6 engine.

Engine failure could occur if the owner uses regular fuel instead of premium fuel and drives the car aggressively.

The recall is expected to begin on June 11.

WASHINGTON — General Motors is recalling 547 2010 Cadillac SRX vehicles equipped with the turbocharged 2.8-liter V6 because of potential engine failure if the owner uses regular fuel instead of premium fuel and drives the car aggressively, according to the National Highway Traffic Safety Administration.

"The combination of regular fuel usage and aggressive driving maneuvers may induce pre-ignition," according to the NHTSA's recalls summary of the problem. "If pre-ignition occurs, you may hear a pinging or knocking sound from the engine. If the vehicle continues to be driven after the onset of this noise, a connecting rod or piston may break, resulting in engine damage, and perhaps engine failure, which would disable the vehicle, increasing the risk of a crash."

Cadillac dealers will reprogram the engine control module for free. The recall is expected to begin on June 11. Owners may contact Cadillac at (866) 982-2339.

Why does this woman still have a job?

1. Don't have it checked out ASAP, you'd be wasting your time since the recall doesn't start till June 11th.

2. The solution to the problem is right there in the text.... use the manufacturer recommended octane till your vehicle is serviced.

3. If you do accidentally fill it with regular, don't be hooning the damn thing.

547 2010 Cadillac SRX Turbos Recalled For User-Induced Engine Failure

By Nelson Ireson


May 27th, 2010

Safety recalls are nothing to snicker about, but some are worse than others. The 547 2010 Cadillac SRXs recalled this week for potential engine failure, for instance, are not even in the same time zone as the millions of Toyotas recalled earlier this year. In fact, the recall isn't even over an inherent defect in the engines, but over misfueling by owners.

According to the NHTSA's Office of Defect Investigations 547 2010 Cadillac SRXs equipped with the 2.8-liter HFV6 turbocharged engine are under recall due to potential engine failure induced by pre-ignition that can occur under aggressive driving--but only when the owner fills the car with regular fuel instead of the premium fuel required by the owner's manual. The problem arises because the engine's computer responds to the retarded spark timing brought on by lower octane fuel by increasing boost pressure. This creates the right conditions of pressure and temperature to cause the air-fuel mixture to pre-ignite.

Pre-ignition occurs when combustion begins before the piston has reached full compression, potentially damaging the engine catastrophically (i.e. breaking connecting rods and pistons, and/or sending pieces that are meant to be inside the block out through it), possibly disabling the vehicle and increasing the risk of a crash.

The problem can be solved--before things go bad--by re-programming the ECU. The recall advises owners to bring their affected vehicles in to the dealers to receive the fix.

Of course, they could also prevent the problem entirely by simply using the proper fuel as stated in the owner's manual. If, however, regular gasoline has been used for a period of time, the engine may need to be inspected for damage, so all affected vehicle owners should take their SRXs in for the recall when notified.

Bottom line: saving $3 on a fill-up isn't worth a blown engine.

Holden-made V6 turbo recalled in US

Knocked up: The Cadillac SRX has been recalled to fix pre-detonating 2.8-litre turbo engines made by Holden.

Dud fuel blamed for Holden engines blowing up in Cadillac SRX SUVs in North America

28 May 2010


LOW-OCTANE fuel has been blamed for a number of failures of Holden-built turbo V6s powering luxury Cadillac SUVs in North America, triggering a vehicle safety recall in the United States.

The 2.8-litre LP9 turbo engine – a 224kW high-performance variant of General Motors’ high-feature V6 that also powers the Holden Commodore and numerous other GM products – is built exclusively at the Port Melbourne plant in Australia for export to Cadillac, Saab and Opel.

However, the finger of blame for the latest problem appears to be pointed at GM Powertrain engineers, not at the factory producing it.

The turbo variant was largely engineered at Saab when it was a GM subsidiary. Working in tandem with their American powertrain counterparts in Pontiac, Michigan, these turbo engine specialists created the LP9 variant for vehicles such as the Saab 9-5 and forthcoming 9-4X SUV, GM Europe’s Opel Insignia OPC and Vauxhall Insignia VRX, and the Mexican-built Cadillac SRX.

They appear not to have anticipated that some American Cadillac SRX drivers might fill their vehicles with low-octane 87 or 88 petrol, despite clear labels warning to use only premium fuel (rated as 91 in the US).

In some cases, the poor fuel appears to have overwhelmed the anti-knock capability of the engine, causing catastrophic failure – the engine blows up.

The problem came to light when an American motoring journalist accidentally filled a test Cadillac SRX with the ‘regular’ 88 petrol, causing engine failure on California’s Highway 101.

The stricken vehicle apparently was shipped back to GM’s Warren technical centre in Michigan where the engine was stripped by engineers for examination and the fuel was independently tested.

GM concluded that a mixture of low-octane fuel and aggressive driving could induce severe pre-ignition, or pinging, to the point that pistons and/or conrods could be damaged, leading to engine failure in severe circumstances.

Although GM says it could not replicate the failure on the road, bench testing of engines did.

The fix is to recalibrate the anti-knock sensor to cope with the low-octane petrol.

Because GM had reports of a number of other similar failures of cars in customer hands, it issued an official vehicle safety recall via the National Highway and Traffic Safety Administration (NHTSA) in Washington, asking owners to return Cadillac SRX 2.8-litre turbo vehicles to their dealer from June 11 to have the engine control module re-programmed.

They have also been warned not to fill up with petrol lower than 91 octane, and not to drive their vehicle if the engine ‘pings’.

As a sweetener, owners of affected vehicles are also being offered a 12-month free maintenance program for their trouble.

A Holden spokesman told GoAuto that the issue was being handled by GM in the US.

The LP9 engine apparently runs a high 9.5:1 compression ratio which, with turbocharging, requires premium unleaded fuel.

In Europe, the engine has been used without apparent trouble in the Saab 9-3 Aero and the high-performance versions of the Opel/Vauxhall Insignia from early 2009, as octane levels are generally higher than those in the US – around 95RON minimum in many areas of the continent.

The Saab 9-3 Aero turbo V6 was also sold in Australia by GM’s Premium Brands network before the sale of Saab to Spyker NV earlier this year, seemingly without ill affect on Australia’s petrol.

The Cadillac SRX – built on GM’s Theta platform that also spawned the Holden Captiva and Chevrolet Equinox – went into production at GM’s Ramos Aripe plant in Mexico last year as a 2010 model.

Offered with a choice of normally aspirated 3.0-litre direct-injection V6 – the same engine as offered in the 3.0-litre Holden Commodore – and 2.8-litre turbo V6, the SRX comes in front-wheel drive and all-wheel drive versions.

A Saab variant, the 9-4X, will roll down the same Mexican production line later this year as a 2011 model, and will also feature the Holden-made 2.8-litre LP9 turbo V6, along with an alternative 2.0-litre four-cylinder turbo engine.

Holden also exports V6 engines to South Korea and China. As reported recently in GoAuto, exports of a Holden-made normally-aspirated high-performance V6 to Alfa Romeo are set to end, as the Italian company is switching to a new Pentastar V6 from Fiat Group partner Chrysler.

Bad decision to use the engine out of a 2006 9-3 Aero. Had this been on Sigma, it could have had the same 3.6 DI the CTS has, and there would be no problem.

Yet another example of SMK clearly not knowing what he's talking about.

The 2.8T has the same exterior dimensions (other than turbo plumbing) as the 3.6DI. If the 2.8t fits, so will the 3.6DI..... or had you forgotten about the Saturn Vue Redline that you love to compare this to?
