NHTSA Complaint #11707830 — 2022 JEEP GRAND CHEROKEE L

In November 2024, Jeep applied an over-the-air software update to my Jeep Grand Cherokee L without my request. Immediately after the update, the forward collision warning system malfunctioned and warning indicators appeared. At the same time, multiple electronic body control and safety-related functions changed or stopped working, including the automatic door locks and several vehicle settings resetting (language, units, and driver-assist preferences). The affected systems are electronic safety and body control components and are available for inspection. The malfunction of the forward collision warning system puts vehicle occupants and others at risk because the vehicle may fail to provide collision alerts intended to help prevent or reduce the severity of a crash. There was no crash, damage, or hardware failure before or after the update. The vehicle operated normally prior to the software update. These problems have continued without interruption for more than 13 months and have not corrected themselves. The issue has not been confirmed by a dealer because Jeep Customer Care has required a paid dealership diagnosis before escalating or correcting a problem caused by its own software update. The vehicle has not been inspected by the manufacturer or any third party. Warning lights and messages related to the forward collision warning system first appeared immediately following the November 2024 update. Jeep/Stellantis has acknowledged similar over-the-air software-related issues in internal technical documentation (STAR Publication Case Number S2108000249, Revision C). This is a safety-related software defect affecting forward collision warning and driver-assist systems.
