In September, when Fiat Chrysler engineers worked with supplier Veoneer to solve a manufacturing problem, they discovered a separate software issue involving certain airbag occupant restraint controllers (ORC). After six weeks of investigation, the FCA decided to conduct voluntary safety recalls of 87,780 2021 Jeep Grand Cherokee L and 11,475 2022 Jeep Wagoneer and 2022 Jeep Grand Wagoneer. This requires 99,255 SUVs to be repaired at the dealership, with an estimated defect rate of 100%.
The problem is that the three internal failures of the airbag system do not result in a diagnostic trouble code (DTC), and these failures should be like this. These failures will cause the driver and passengers to fail to deploy the airbags correctly, and will also disable the knee airbags. These failures increase the risk of injury in a collision. However, since they will not throw out any diagnostic fault codes, the airbag warning lights will not light up to warn the driver and passengers that there is a problem with the airbag system. Jeep reported that it was not aware of any casualties caused by this defect.
FCA stated that it will start sending letters to inform vehicle owners sometime around December 30th. Owners can take their Jeep to the dealer to reprogram OCR for free. At the same time, owners of affected vehicles can call the FCA’s hotline 1-800-853-1403 and dial the voluntary recall number Y79. They can also call the National Highway Traffic Safety Administration’s Vehicle Safety Hotline 1-888-327-4236, or visit www.nhtsa.gov to view the recall information. The NHTSA campaign number is 21V873000.
