The JL Generation of the Jeep Wrangler may have improper frame welds according to an investigation by the National Highway Traffic Safety Administration (NHTSA). The investigation started after a Wrangler owner complained about a frame that had been improperly welded at the factory. As a result of that improper weld, the owner found a number of other problems stemming from the original issue.
While no findings have been released, there is enough evidence for the NHTSA to warrant further investigation and the agency has asked FCA for more information regarding the issue. The NHTSA seemed to think that FCA's explanation "did not adequately address whether the frame weld quality deficiencies compromise the structure integrity of the vehicles, and therefor may pose an unreasonable risk to motor vehicle safety."
The investigation further aims to determine if the earlier reported 'death wobble' is related to the frame welding issues. FCA issued a fix for the 'death wobble' last month, but did not turn it into a full recall. Jeep will install a new steering damper, free of charge, to anyone who wishes to have the work completed.
