2020 Jeep Grand Cherokee problems

Filed Oct 16, 2026 · Electrical · IA

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.

At 29835 miles, my 2020 Jeep Grand Cherokee suffered a severe transmission slip/harsh jump. I took it to an authorized dealer on May 5,2026. The dealer charged $559, plus misc. charges of $12.00 and54.25 tax. They performed a transmission inspection, a quick learn to reset points, and noted VEH has an adaptive transmission. Vehicle needs to be driven to accommodate drivers pattern. The transmission is still actively slipping creating an extreme safety risk of sudden power loss in traffic and on highway.

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 dashboard material has come loose and bubbled up. This issue is concerning in that: 1) the structural integrity of the dashboard itself is uncertain; failed adhesive alone can't account for this (my photo doesn't do it justice), 2) if allowed to continue, the material has the potential to fully come loose, thus leading to disruption of the visual field to safely see, and 3) materials and debris have the potential to become trapped under the bubbled-up sections, leading to additional concerns such as mildew or mold. It does get warm in Sacramento, but my car is parked inside or in a covered area 95% of the time. In fact, when I first noticed it, it had been parked in a shaded parking garage. I have been in zero accidents. Unfortunately, the other issue, is no one seems to be willing/able to fix it, and it sounds like I will have to be involved in an accident in order to get it done. Which is NOT something I want to do.

Exhaust system design defect. Original manifold system started to fail at approximately 40,000 miles, allowing CO gasses to enter vehicle cabin exposing passengers, including children, to potentially deadly exhaust fumes. Jeep, Jeep Service Centers have known since at least service bulletin 09-19-23 that the hangers and brackets used in the manifold system are not robust enough in design to “accommodate thermal expansion and engine movement without breaking or leaking.” I was never alerted to this. Addressing this via an unnoticed bulletin rather than a recall not only put me in physical danger, but ran out the clock so it could not be addressed as a warranty issue. Apparently, the manifold warps, gaskets fail, the vibration shears support bolts, and the carbon monoxide leaks into the car through the ventilation system upon warmup. Depending on severity perhaps the entire drive. Attached file is a $4200 estimate presented to me by the dealership where I originally purchased the car, preparing me for what I might have to pay out of pocket to fix the leaking exhaust system. There was no preemptive maintenance for this issue I could have had done, aside from not driving my car. Ever. I assumed when I bought the car that the manufacturer would not knowingly allow me to purchase a vehicle that pumps exhaust fumes directly into the cabin. I was wrong. This is a defect Jeep is obviously well aware of, and they chose to put their customer’s in harm’s way rather than taking action.

I am writing to make you aware of a safety issue that I have encountered with my 2020 Jeep Grand Cherokee Laredo. On August 21, 2026, the gas pedal/throttle control just fell off as I was driving myself and infant on a busy three lane thoroughfare in [XXX]. I went to slow down the car by braking, but it was very difficult. I went into an empty bus lane so as not to get rear ended or crash into something. Finally, the car systems ceased. No warning lamps came on ever or any messages. I had no problems with the car prior to this occurring. As I said previously, I had my infant in the car with me at the time and never expected for a gas pedal/throttle to literally fall off. I didn't think that cars would be made for this to ever happen. This could've been a major tragedy. I usually commute to work on major highways with tractor trailers and trucks, but I was off that day luckily. We could have been killed. I had to have a flatbed bring it to a Jeep dealer in Nanuet, NY where they took possession of the car and car part. I did take phots of the part though. The Jeep dealer Rockland Chrysler Dodge Jeep Ram in Nanuet, NY repaired the Jeep. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The factory-installed 8.4-inch Uconnect touchscreen/display in my 2020 Jeep Grand Cherokee is delaminating internally causing bubbling under the screen surface. The layers of the touchscreen are separating even though the screen has not been physically damaged. The Uconnect system and vehicle are available for inspection upon request. The delamination affects the touchscreen used to operate and display multiple vehicle functions. As the screen deteriorates, it can become difficult to read or operate and may result in unintended or “ghost” touchscreen inputs. This can create a driver distraction while the vehicle is moving and may interfere with the driver’s ability to reliably use information and functions displayed through the Uconnect system, including the rear-view camera display when backing up. The condition appears to be progressive and raises concern that the display could become increasingly unreliable. Yes. The vehicle was presented to an authorized Jeep dealership, and the delamination of the factory Uconnect touchscreen was confirmed. The dealership also attempted to determine whether Stellantis would provide repair cost assistance, but advised that its system would not allow a goodwill request because of the vehicle's expired warrenty. The car is only 6 years old and has less than 60,000 miles. Stellantis refuses to provide any assistance. Jeep dealership states it is a $1500 repair. The vehicle and Uconnect screen have been inspected by an authorized Jeep dealership. The vehicle has not been inspected directly by Stellantis, police, or an insurance representative. There were no warning lamps or vehicle warning messages before the screen began delaminating. The first noticeable symptom was visible separation/bubbling within the touchscreen display. The condition has progressively worsened. There was no impact, physical damage, or other event that caused the screen to separate. Symptoms first appeared in August 2026.
