2022 Jeep Grand Cherokee L electrical system problems

“The radio has been replaced 3 times by the jeep dealer. The issue is over the air updates of the uconnect radio system fail and put the radio in Italian language disable foward collision safety features and other car features that I paid for need to also be enabled by the dealer that the dealer can only activate due to Stella’s firewall issue that prevents people to work on their own cars and require the dealership software to fix. The radio replacement does not fix issue even though they replace 3 times. They don’t actually have a fix and they are just putting band-aid on the problem. The update they send to the radio over the air corrupts the cars options.”

“The contact owns a 2022 Jeep Grand Cherokee. The contact stated while driving at an undisclosed speed, another vehicle struck the rear of the vehicle at approximately 70 MPH. The auxiliary warning lights were illuminated. The contact stated that none of the air bags were deployed during the crash. The contact expected the air bags to deploy and was concerned that they failed to do so. The contact and his daughter both sustained injuries as a result of the crash. The contact reported neck whiplash, cervical and lumbar neuropathy, sciatica, herniated discs at L4-L5, drop foot, several contusions, rib injuries from the seatbelt, and injuries to the left hand, thumb, and wrist after the contact's daughter's hand was forced into the dashboard. The contact also received 14 stitches near the left eye and was placed in a wheelchair. The contact stated that surgery was recommended for his neck and lower back and that he and his daughter received physical therapy and chiropractic treatment. Following the crash, the contact also experienced additional vehicle issues, including the rearview camera that was intermittently darkened, an auxiliary battery that was not…”

“Hard shifting occurred. Then service 4WD light came on dash. After an oil change, the light went away, but the hard shifting is still there. An independent dealer replaced my transfer case as well as completed an update to the transmission. The hard shifting came back even worse, with almost every gear. Took to a Dodge/Ram/Jeep dealership who completed a TSB 21-015-23. Their next recommendation is to replace the valve body and if that doesn’t fix it, then replace the transmission. They stated this recommendation came directly from Stillentis. Since this is a known issue from Stillantis, they should be issuing a recall immediately. Failure of the transmission can cause sudden power loss, unpredictable acceleration, stalling, and fire hazards. These things can in turn cause accidents and safety hazards.”

“Forward Collision Warning has been disabled since a forced OTA software update in August of 2024. Jeep has issued a STAR report to their dealers (S248A000013). Jeep acknowledges it is an issue, but fails to cover the remedy. Dealer wants $200+ to diagnose plus the cost of the software refresh. The system forces you to take the software update, removes a key safety feature, and then Jeep wants you to pay to restore it. This is a major issue with this model covered in the forums and should be addressed via recall. [XXX] [XXX]”

“The initial safety issue began with the rear-view camera going blank and the Uconnect 5 screen freezing while the vehicle was operating in reverse. My vehicle's service record indicates that Safety Recall 24V-436 / FCA Campaign 79B was marked as "Completed" in the FCA system on June 19, 2024—even though the official recall was not initiated until around June 25, 2024, and no physical software update was performed at that time. To resolve the recall, I took my 2022 Jeep Grand Cherokee L to Performance Chrysler Dodge Jeep Ram in Delaware, Ohio, where technicians updated the software to version FCA-MY24.U33.43-PROD. Immediately following this dealer update, several core vehicle and safety functions failed: Forward Collision Warning (FCW): The FCW system automatically turned off, and the option to re-enable it completely disappeared from the vehicle settings menu. Vehicle Safety & Operational Controls: Automatic speed-sensitive door locking and paddle shifter functionality were completely disabled. I returned the vehicle to the dealer, where technicians reflashed the software to restore the user configuration options and re-enable FCW. However, the Uconnect system…”

“This model of Jeep has a documented history of having software problems that occur resulting in huge safety issues. I am filing this report because Jeep has not successfully solved this issue leading to regular ongoing safety concerns. Jeep themselves have issued several STAR reports on this, and a simple internet search will show thousands upon thousands of posts of owners with recurring issues. The specific safety concerns regarding seat positioning while moving, language change of instrumentation and critical alarms, metric changes to critical items like speed, and failure of front collision sensors. The issue begins with the driver seat changing its position while driving. While driving the seat will suddenly recline almost to a lay down position which is a safety risk. After some time fighting this, the car will eventually have a computer issue where the language changes to Italian, and cause the front collision sensors to be disabled. There is actually no issue with the sensors, it’s a software glitch that causes the sensors to be deactivated. In order to fix the issue, the car has to be taken to the dealership for several software updates and…”
