2020 Jeep Grand Cherokee electrical system problems

“This concerns the Auto Start Stop (ASS) battery installed at the factory that has the vent hole in the wrong place and was improperly installed so that the vent tube could be dislodged and allow hydrogen gas from charging into the cabin. Both the main battery and ASS battery are installed under the passenger seat and vent outside through a hose. I discovered this situation while replacing the main battery. I contacted Stellantis via email (with and explanation of the numbers in the photo) and they were not willing to address the issue. I have attached a copy of the email and also a photo of the battery compartment. Also, the new ASS battery has the vent hole in a new location. It is my opinion that this is a safety issue.”

“ABS module completely malfunctioned from a shortage. Threw up 7 different codes, even threw up my check engine light for a bit. Can’t even use cruise control because my “memory system” and “park sense” are unavailable. Sometimes it makes the wheel super stiff and the acceleration and break pedals super sticky. I see many recalls for 2020 Jeep Grand Cherokee’s, and believe mine should be included. I should’ve have to pay $3,000 out of pocket for something a ton of people are reporting as an issue. I found one reported a few months back with the same issue.”

“The screen in my vehicle which controls alot of the functions like temperature volume sos emergency calls is experiencing delamination cause the screen to ghost touch things which is a safety hazard when driving in the event of an accident i wont be able to press the button on the screen for help”

“My screen has started to delaminate I’m very worried it will soon completely not work . I would like to have this issue addressed by jeep themselves I refuse to pay for a new one this vehicle has 40,000 miles and is 6 years old it should not be happening . I’m extremely unhappy .”

“On the 26th of April 2026, the transfer Case on my 2020 Grand Cherokee (with less 114,000 miles) failed during highway travel. This resulted in a sudden downshift and temporary deceleration followed by illumination of “Service 4wd” display. A short time after, the “Service Electronic Stability Control” indicator displayed followed by another downshift and the unattended transition of the 'Select_Terrain' from 'Auto' to 'Snow'. We were unable to turn off these settings. On the next day, we returned the Jeep to our CDJR dealer for repair. After inspection, the service agent reported that the Jeep experienced a “Transfer Case failure” and further recommended that I consider [purchasing] a new vehicle as these issues seem to be piling up. Failure of this nature is not normal wear. I have purchased 5 Jeep vehicles over the past 40 years and 4 of our Jeeps had over 250,000 miles of service without dangerous, catastrophic engine or drive-train failure such as this. This situation should remediated by the manufacturer and any affected components repaired or replaced. Finally, it should be noted that 3-days prior to the failure, the same CDJR dealer provided a…”

“The uconnect touch screen is delaminating. It is causing issues with being able to use the backup camera with accuracy because the delamination causes a visual distortion. Also, it has been causing issues with the controls where it repeatedly gets stuck and ghost touches options in the vehicle while driving, which is concerning. The delamination started as a small spot and has rapidly increased to half the screen. This is clearly a widespread chronic issue/defect with many Jeep GC models, if you look online. The screen is a big component in operating and functions in the vehicle. Having a defect which causes sight impairment and control changes while in motion is dangerous.”
