2023 Jeep Grand Cherokee L Problems

The contact owns a 2023 Jeep Grand Cherokee L. While the contact’s husband was driving 70 MPH, there was an abnormally loud sound coming from the rear of the vehicle, and an unknown metal object detached and flew off the vehicle into the traffic behind the vehicle. The vehicle was pulled over and inspected, but there were no signs of the failure. The vehicle was towed to an independent mechanic, who diagnosed the vehicle and determined that the suspension coil had dislodged and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 33,000.

I was driving on the NYS thru way with my family and my rear suspension coil came out while we were driving. The part was not rusted or looked defected. When I took it to the dealership they said a recall for this issue had been repaired in June of 2023 prior to me owning it. I purchased the vehicle on October of 2024. I called corporate and they said there is nothing they will do for me. I paid $500 to fix an issue that should have been completed properly. This is now a safety concern for me and I fear driving it will happen again.

The starter/starter solenoid and related engine oil sealing have failed three times. Most recently on 6/18/2026, and previously in 2024 and 2025, the vehicle would not start: the dashboard illuminated but the engine would not crank. The engine then began smoking and a burning electrical smell entered the cabin. My wife and young child were in the vehicle. The vehicle was rendered completely inoperable and had to be towed each time. Safety risk: an engine that smokes and emits a burning electrical odor upon attempted starting presents a fire hazard to occupants. On the most recent occurrence the failure happened at a fuel station with my family present, over 1,000 miles from home, stranding us for seven days. Dealer confirmation: yes. On the two prior occasions a franchise dealer diagnosed a defective starter solenoid and replaced the starter. Both repairs failed and the identical failure recurred. On the most recent occurrence, a different franchise dealer found that a plug sealing an unused opening on the engine block was missing, allowing engine oil to spray onto and saturate the starter, destroying it. The starter and the plug were replaced. All failures were documented on dealer repair orders, which are available on request. Inspection: the vehicle has been inspected and repaired by franchise dealers on all three occasions. No police or insurance inspection. The manufacturer has been notified through its customer care department, which has open case records on this vehicle. Warning indicators: none. There were no warning lamps, messages, or symptoms prior to any of the three failures. The vehicle simply would not crank, followed by smoke and a burning electrical smell. This vehicle has spent approximately 60 days out of service since purchase and has had persistent electrical problems documented since 2023. Despite repeated dealer repairs the same failure mode continues to recur. I am reporting this as an unaddressed safety defect.

While driving, the vehicle displayed a "Service Shifter" warning with no prior warning lamps or symptoms. The transmission then dropped out of Drive into Neutral on its own while the vehicle was moving, causing it to roll before the vehicle automatically shifted itself into Park and applied the parking brake. The vehicle could be shifted back into Drive but repeatedly slipped out of gear into Neutral again within about a minute each time. After parking, the gear indicator display (P/R/N/D) stopped illuminating entirely and has not returned. The vehicle is now unresponsive to the rotary shifter and is stuck in Park with no way to shift into any gear. This failure matches the description of open recall 30D (shifter module software defect causing loss of transmission gear position display), though my vehicle was not part of the currently identified population when checked against the VIN lookup. The vehicle is currently undriveable and has not yet been inspected by a dealer or independent shop.

The contact owns a 2023 Jeep Grand Cherokee L. The contact stated that while his wife was driving 20-25 MPH, the accelerator pedal became stuck, and the vehicle drove through a stop sign and intersection, swerving into a farm, and crashed into a pole in order to bring the vehicle to a stop. After removing her foot from the brake pedal, the vehicle suddenly accelerated. The contact stated that the air bag had not deployed. There were no injuries sustained. There were no warning lights illuminated. A Police report was filed. The vehicle was towed to a tow lot. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and suggested that the vehicle be towed to the dealer. A claim was filed with the insurance company. The failure mileage was approximately 45,000.

I am experiencing two serious issues with my Jeep that have raised significant safety concerns. First, the front passenger seat's lumbar bladder repeatedly inflates on its own, making the seat extremely uncomfortable and causing severe back pain for anyone sitting in it. I have been informed that this is a known issue affecting many Jeeps of this model. The dealership previously deflated the lumbar bladder under warranty, but now the problem has returned. I was told I must pay for the repair out of pocket because the previous deflation supposedly voided or disqualified the warranty coverage. I do not believe I should be responsible for paying to fix a recurring defect that was previously addressed under warranty. Second, the Electronic Brake System (EBS) warning light comes on randomly, and when it does, my vehicle unexpectedly slows down or comes to a stop. This creates an extremely dangerous situation while driving. I have been fortunate to avoid a collision so far, but I am very concerned for my safety and the safety of my four children, who regularly ride in the vehicle with me. I am requesting that these issues be thoroughly investigated and repaired at no cost to me, as they involve recurring defects and serious safety risks. I also request a written explanation of why my warranty claim for the recurring seat defect was denied after the dealership's previous repair.

Vehicle continuously has a problem with the alignment and tow link issues suspension problems that cause the vehicle to go out of alignment often. This is a continuing problem that has me going in for repairs more often than I should have to over the last 2 years. Many repairs for the same problem.

The vehicle is currently inoperable and has been in the shop over 60 days. Intermittent power loss resulting in losing some safety components while driving such as power steering, adaptive breaking etc On 7 different occasions it has left my family stranded and even once completely locked out with all car seats and identification inside. We were unable to open the vehicle and it had to be towed. Thankfully all children were out of their car seats and outside of the vehicle. Purchase date : Feb 2025 13,000 miles 7 instances and has been to a dealership each time and they cannot figure it out. I am without a vehicle Videos and service papers are available but unable to upload the videos here. We have a case manager with Stellantis but getting nowhere. Urging others to file complaint as there are many online Vehicle is at Hoover Chrysler Dodge Jeep in Moncks Corner , South Carolina where is has been each time there was an issue. 854-300-3800

Was driving the vehicle normally, roughly 33,300 miles. All of a sudden, multiple malfunction lights came on, I believe the ABS and something else, can't remember which one. When we applied the brakes , there was no assist, we had to depress the pedal all the way down and basically stand on it to slow down and still ended up stopping partway through an intersection due to the lack of power brakes, we were extremely fortunate there was no other vehicles driving through or stopped in front of us, it could have killed us and/or other people. As the vehicle is out of warranty (by time) we looked into it ourselves and determined there were two DTCs, U0418 (invalid data, brake system control module) and P057B (Brake pedal position sensor circuit range/performance). We looked at the brake pedal and determined that a primary component of the "brake pedal simulator sensor" which is a part of the entire brake booster assembly. The retaining cup for the spring and internal components had come separated from the main body and caused the sensor to go out of range and the computer to disable power brakes entirely relying entirely on the backup hydraulic master cylinder. As this required replacement of the brake booster we decided to have it towed to the dealership to deal with. It was a few weeks before we had it towed and while it sat in the driveway the module not going to sleep resulted in both the main and aux batteries being fully drained and ruined, requiring replacement. The dealer replaced the power booster and provided the old component at our request for the purpose of filing this report in case it is requested for an investigation. The total cost was $1800. We consider this a severe safety issue and thus am filing this report with all documentation and have the part on hand if requested.

There have been many components and issues that were and were attempted to be repaired. The vehicle is available for any inspection needed. I am afraid to drive the vehicle. My safety, my family’s safety and everyone around us front behind it doesn’t matter everyone is at risk. The vehicle for no reason at all just stopped. A very intense and.violent stop then the automatic braking and pedestrian warnings alerts came off. The vehicle did NOT come to a slow stop it felt like we hit into a brick wall. The dealership is never able to recreate or fix anything. Doubt they even try. They don’t put much effort into trying to recreate the issue.

Vehicle has experienced repeated electrical system failures affecting engine operation, safety systems, and interior electronics from April 2025 through April 2026. Details: April 2025 (under warranty): Vehicle lost power and died. Dealership replaced batteries. December 2025: While driving, multiple warning lights (check engine, blind spot, lane departure, forward collision, accident avoidance) flashed repeatedly. Battery died and was replaced by AAA. Vehicle taken to dealership due to safety concerns; dealership found no issues. March 2026: Same warnings occurred again while driving. Vehicle lost all power while stopped at a red light. Hazard lights did not work. Gear selector knob rotated freely and could not be put in park. After opening the hood, vehicle restarted but windows, powered seats, and infotainment stopped working. Dealership replaced fuse array. April 2026 (~3 weeks later): Vehicle would not start. After accessing battery under passenger seat, vehicle turned on with alarm and lights flashing. Same warning lights reappeared while driving. Interior electronics (windows, seats, infotainment) remained non-functional. Safety Risk: Complete loss of power in traffic, inability to use hazard lights, failure of driver-assistance safety systems, and inability to shift into park create significant risk of crash or injury. Inspection/Repair: Vehicle inspected multiple times by dealership and AAA. Batteries and fuse array replaced. Issue persists and root cause is UNKNOWN. Warning Signs: Repeated warning lights prior to failures, including check engine and multiple safety system alerts.

This vehicle had a recall for rear tire suspension popping off the vehicle. While my vehicle was parked in my driveway the rear suspension coil popped off the rear of my vehicle as described in the recall. I then took the vehicle to the dealership they first gave me the run around for a couple of days then when they could not explain why the diagnostic test came back as failure for unknown reasons I argued that they had nothing else to relate the issue to as there was no signs of anything else. After days of back and forth they finally agreed to fix it under the recall. Upon receiving the vehicle back they refused to give me any paperwork or reciept for the incident and stated they would email it it to me. I never received anything. Also when I went under the vehicle to check the work done I can see they replaced it with the original type of parts and did not give me updated parts like they claim they did. Again I have no paperwork to show what they did.

I rented this car from Fox Rental Cars at Seatac Airpot between 2/18/26 and returned 2/23/26. While in the AUTO setting for headlights, the high beams suddenly shut off and quick working. Then the tail lights quit working. I did not know the tail lights were inoperable until I was pulled over. When I shut off the vehicle and turned it back on, the tail lights came back on and I was released without a ticket. Then I got pulled over again on the 21st about a mile from my family home. The tail lights did not turn back on at all but the officer allowed my brother in law to come follow the vehicle home since I was so close. I ended up only driving the car during daytime hours. When I called the customer service line, I could not understand a word the person was saying so I gave up and decided to just drive during daylight hours for safety. When I reached out to Fox management, I was told there were no issues with inoperable tail lights or high beams even though when I checked the vehicle back in, the attendant noted on an incident ticket that the tailights were not working. He did not note the high beams not working on the ticket but they were still inoperable at the time of drop off. If this rental car company rents this vehicle to anyone else, someone could be killed. I asked them for a refund and they denied it based on them saying there was no issues. I not only reported this for a refund but SAFETY reasons so the next driver of the car doesn't get hurt. They clearly never inspected the issue any further if they say the tailights and high beams work. They did not work. I have included my rental invoice, incident ticket provided by FOX rental return attendant, vehicle information sheet, and email from management at Fox stating there were no issues because she didn't want to give me a refund.

The contact owns a 2023 Jeep Grand Cherokee L. The contact stated that while the daytime running lights were activated, the high-beam headlights were inoperable. The contact had to turn off the daytime running lights for the high-beam headlights to engage. There were no warning lights illuminated. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was not diagnosed or repaired. The contact called another local dealer, Chapman Las Vegas Dodge Chrysler Jeep Ram (3470 Boulder Hwy, Las Vegas, NV 89121) and was informed that the vehicle was working as designed. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was unknown.

The contact owns a 2023 Jeep Grand Cherokee L. The contact stated that while driving at an undisclosed speed, the infotainment display was frequently powering off and on and failed to display pertinent vehicle safety information; however, the vehicle returned to normal functionality, and the contact continued driving to the destination. Upon the return trip to the residence and loading groceries into the rear of the vehicle, the liftgate started to close independently. The contact made several attempts to trigger the liftgate proximity sensor and pinch protection system to prevent the liftgate from closing; however, the vehicle failed to detect the presence of a person, and the liftgate continued to close. In response, the contact jumped into the rear of the vehicle to escape possible injury from the liftgate closing prematurely. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 59,000.

Rear liftgate will not open, attempts about 1/4" of movement then back in to lock and gives an object detected alert on driver's instrument cluster when nothing is behind vehicle. After multiple attempts to open the "Lift Gate Temporarily unavailable" alert presents on driver's cluster. This occurs from inner switch or trying to open from the lever and the key fob next to license plate. Cleaning cameras and bumper sensors seems to work once but the issue reoccurs immediately or after few cycles of door. Power cycling via pulling fuse for liftgate and disconnecting the bumper sensors does not change anything it still will not open and displays object detected alert. Took to dealer verified issue and lubed and adjusted lock, tested ten times and door opened. one day later wife trying to open liftgate would not open. this morning tried and did first couple time then didn't wipe one sensor, and it opened tried again would not open, wiped all sensors and cameras would not open. took to dealership, service advisor attempted would not open issue verified. this issue is intermittent as brought home tried when got out of car would not so approx. 20 mins after dealership visit. Then I typed this form up and went back out and attempted and it opened multiple times. I am concerned not being able to access my fire extinguisher or first aid kit rapidly if need be.
