2022 Jeep Grand Cherokee L Electrical system Problems

“On Friday, January 16, 2026, I was involved in a head-on collision. During the accident, the airbags did not deploy, and the seatbelt failed to lock, which resulted in me not being properly restrained. As a result, I suffered a mild concussion along with significant bruising. In addition to this serious safety concern, we have made numerous complaints regarding ongoing electrical issues with the vehicle. These include the screens frequently changing languages and measurement units, blacking out entirely, or becoming unresponsive. …”

“1) The 'Forward Collision Warning Off' light has continued to show on my dashboard, even though everything in the system indicates that it is on. 2) From time to time, usually when using the remote start, the system will change settings to Italian Language and also change temp to C rather than F. 3) On at least 3 occasions, when I start the car, all warning lights turn on, such as Service Power Steering, Lane Assist, Automatic emergency Braking, etc. I have to turn the car completely off, wait a few minutes, and turn back on to have thing behave as normal.”

“Forward collision warning system not working. Light on dashboard says system disabled. Paddle shifters also disabled. Temperature readings in metrics and language keeps changing. This is available for inspection if needed. We bought this car because of the collision warning and braking system safety features and none of them work. This puts our safety at risk. The dealer has updated the system but unfortunately it was only a temporary fix. The jeep dealer confirmed the issue and states there is no permanent fix for the issues. It first appeared in July and has been ongoing.”

“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. …”

“I purchased my vehicle in Sept. 2022. Issues began Nov. 2024. At first my radio screen was glitching and at the same time my car did a software update, it reset all my settings and my AEB system was disabled and would not turn back on regardless of how many times I turned it back on. The dealer did a manuel software update, replaced my screen (I paid the $100 warranty deductible) and it fixed the problem. A month and a half later it happened again without the update and my screen again was glitching. All my settings were changed and my AEB system was disabled. …”
