2020 Jeep Grand cherokee

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.

The radio is delaminating. This is a common complaint for jeep. They need to fix this problem

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

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.

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 .

Radio / navigation screen de-laminating. Radio controls malfunction while driving. I am the fist and only owner of this vehicle. Car is garaged , and only has 63,000 miles on it. No environmental reason why this would be happening. I have went to dealership service department and they stated it was not covered by my extended warranty . I have also reached out to Jeep customer care with no resolution. The screen controls the AC , steering wheel heating , seat heating , phone Bluetooth, SOS , etc .

While driving on the interstate at highway speeds, the vehicle suffered a sudden and complete loss of motive power without warning, causing the engine to stall. The vehicle became a severe safety hazard in active traffic as power steering and power braking assists were greatly reduced, nearly causing a high-speed rear-end collision before I could safely coast to the shoulder.Upon investigation, the vehicle completely ran out of gasoline, despite the dashboard fuel gauge explicitly indicating at least a 1/4 tank of fuel remaining.This is the second time this exact failure has occurred. The first instance happened during the vehicle's factory warranty period. At that time, the dealership misdiagnosed the issue and replaced the auxiliary battery, failing to address the underlying fuel delivery defect.The vehicle currently has 37,950 miles. The defect appears to be a failure of the auxiliary fuel sending unit/siphon pump inside the saddle-style fuel tank layout. This failure prevents fuel from transferring to the main pump, starving the engine of fuel while falsely reporting to the driver that gas is still available. This is a severe manufacturing defect that actively misleads the operator and causes unexpected stalling at highway speeds.

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 100,00-Mile 'service' that included "Op1 DMS All wheel Drive Fluid Exchange".

I am submitting this complaint to report a serious safety concern involving my 2020 Jeep Grand Cherokee. At approximately 44,000–45,000 miles, the vehicle suffered a catastrophic engine failure. This was extremely alarming considering the relatively low mileage of the vehicle. The most serious concern occurred while I was attempting to drive the vehicle to the service center. The condition of the vehicle became so severe that I genuinely feared the vehicle could catch fire while I was still inside it. I was terrified for my personal safety and concerned that I could be seriously injured. This was not simply an inconvenience or an ordinary mechanical repair. In my opinion, the circumstances surrounding the engine failure created a potentially dangerous safety situation. The vehicle has subsequently remained at the dealership/service facility for an extended period while the engine issue has been addressed. I contacted Jeep/Stellantis regarding the engine failure. Stellantis offered approximately $13,000 in goodwill assistance toward the repair while requiring me to contribute approximately $3,200. However, my primary reason for reporting this matter to NHTSA is not the financial dispute. My primary concern is SAFETY. I am extremely concerned that an engine could experience such a catastrophic failure at approximately 44,000–45,000 miles and create circumstances in which I feared the vehicle could catch fire while being driven. As a result of this incident, I have completely lost confidence in the safety and reliability of this vehicle and do not feel safe driving it again, even if the engine is repaired or replaced. I respectfully request that NHTSA review this complaint and determine whether similar engine failures, fire-related incidents, or safety complaints have been reported involving 2020 Jeep Grand Cherokee vehicles or vehicles equipped with the same engine. I am prepared to provide my VIN, dealership repair orders, diagnostic information, service re

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.

I am reporting a potential safety issue involving my 2020 Jeep Grand Cherokee Limited X. The vehicle developed a condition in which it would not stay running. I brought the vehicle to an authorized Jeep dealership, Valley Motor City in Cuyahoga Falls, Ohio, for a scheduled service appointment on May 19, 2026. The dealership diagnosed and completed approximately $5,200 in repairs. On June 11, 2026, I was informed that the repairs had been completed, but the vehicle still would not stay running. The vehicle has remained at the dealership while technicians have continued attempting to determine the cause. After I escalated the matter to Jeep/Stellantis Customer Care, I was advised that the dealership is attempting to obtain additional diagnostic information and that an engine replacement may now be under consideration. I was also advised that the dealership is expected to complete higher-level technical review procedures and may request assistance from a Stellantis technical specialist if the cause still cannot be determined. I was later advised that the dealership was expected to provide follow-up information to Jeep/Stellantis by Tuesday, July 14, 2026. On the evening of July 14, 2026, the Jeep/Stellantis case manager advised me that the dealership had not followed up with her, and that she would follow up with the dealership and escalate the matter to her manager. The vehicle remains unresolved after 2 months of diagnosis and repair efforts. I am reporting this because a vehicle that stalls, shuts off, or will not remain running may present a safety risk, particularly if the condition occurs during operation. I do not know the root cause and do not want to speculate. I am requesting that this report be recorded as a potential safety issue involving a 2020 Jeep Grand Cherokee Limited X.

The contact owns a 2020 Jeep Grand Cherokee. The contact stated that while driving at approximately 20 MPH, the check engine warning light illuminated, and the vehicle jerked and lost power. The vehicle was taken to an independent mechanic, where the failure could not be replicated. The vehicle was then taken to another independent mechanic, where it was diagnosed that the camshaft, battery, and two oil valves in the starter needed to be replaced. The vehicle was not repaired. The vehicle was towed to a dealer, who provided the same diagnosis. The battery, starter, and two valves were replaced. The contact stated that the failures persisted while driving on several occasions, with the message "Oil Overheated" displayed, and the temperature warning light illuminated. The vehicle was then towed to an independent mechanic, where it was diagnosed that the camshaft needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 114,369.
