2022 Jeep Grand Cherokee L

A warning light popped up to tell me this system was disabled on my dashboard, at the same time the system switched to Italian and all of the units of measure switched to metric without warning. I took it in to the dealership and they reset everything, replaced the radio/computer, and assured me everything was working. Within a week, the same error occurred and the same issues. I took it back to the dealership and they acted like they had no idea why, but would look into it. While waiting I searched online and discovered a notice from Chrysler dated in 2024 saying this issue was occurring and dealerships should just reset the system. I also discovered a multitude of similar issues being reported by other owners of Jeep vehicles across various message boards. When I brought the "Star bulletin" to dealers attention, they admitted they were aware of the issue all along and had no idea when/if it would be fixed as it was an issue with the software in the vehicles themselves that Chrysler would need to fix. So, I was sent home with a vehicle that is not operating correctly. I have to assume the front collision and emergency braking is not working (along with quite a few other features I have discovered), and frankly I have no idea what safety features are or are not working as they could not (or would not) tell me what all was affected.

ABS , Traction Control, Power brake booster, AEB inoperative after routine brake pads/rotor service. Vehicle was put into service mode via touch screen radio, rear brake service performed. Upon initial brake pedal application, required to exit service mode for rear brakes, to return caliper piston contact to brake pad. The vehicle disables abs and supporting system and sets codes c0050 , c2227 . As a technician my opinion is the extra brake fluid required to take up open space after service is discharged via accumulator into the brake system with no resistance or pressure due to caliper pistons expanding to the brake pads. These faults render the power brake boost abs and multiple other safety systems inoperative until a dealer level scan tool can perform abs initialization, and a hydraulic prove out test, and clear all codes, even with all code cleared power brake boost was lack just at best on initial test drive after service. A basic routine service should not affect a vehicle as adversely as this. While dealers may know what's going on your independently run shops and DIYers may return unsafe vehicles to customers/owners. This is the 3rd vehicle I have personally experienced this with. I will up load separate reports with those vins accordingly.

The forward collision warning turns off on it's own. Jeep did an upgrade and now the radio turns off and on by itself, changes in preference happens without warning and forward collision warning stays lit. Jeep has replaced the radio 3 times since and I've been to the dealership at least 15 times to address the issue but the issue has not been resolved. This has gone on since 2023. Jeep is aware of the issue because i read a memo addressing it at the dealership but they would not provide me a copy of it.

The infotainment center went to error on Jeep with less than 60,000 miles. Owned from new 2 years. The infotainment center can not be accessed and it makes modifications on its own. Like choosing different language of Italian and using euro measurements. There is no way to change this. The biggest issue is that it turned off safety feature which I believe is the forward collision warning. There is no way to change safety setting with out infotainment system. It also believed to be causing battery to drain. Jeep will not assist.
