2021 JEEP GRAND CHEROKEE L Complaints

ABS , Traction Control, Power brake booster, AEB inoperative after routine brake pads/rotor service. Vehicle was put into service mode via touch screen radio, rear brake service performed. Upon initial brake pedal application, required to exit service mode for rear brakes, to return caliper piston contact to brake pad. The vehicle disables abs and supporting system and sets codes c0050 , c2227 . As a technician my opinion is the extra brake fluid required to take up open space after service is discharged via accumulator into the brake system with no resistance or pressure due to caliper pistons expanding to the brake pads. These faults render the power brake boost abs and multiple other safety systems inoperative until a dealer level scan tool can perform abs initialization, and a hydraulic prove out test, and clear all codes, even with all code cleared power brake boost was lack just at best on initial test drive after service. A basic routine service should not affect a vehicle as adversely as this. While dealers may know what's going on your independently run shops and DIYers may return unsafe vehicles to customers/owners. This is the 3rd vehicle I have personally experienced this with. I will up load separate reports with those vins accordingly.

Passenger seat back inflated so you cannot sit in the seat safely. Not sure if faulty massage chair component or lumbar support. Almost like an air bulge.

While driving my kids home from the school the vehicle stark jerking and kicking in the back while I was accelerating. Then the vehicle stopped shifting gears. I pulled to the side of the road turned off the car, turned it back on and it worked fine. I have this incident twice in two years. Secondly the paddle shift gear showed as disabled when I want to use manual gear. Checked the dashboard and there is no option saying enabled or disable peddle Shift gear. Thirdly the forward collision warning light is on on the dashboard. From time to Time the vehicle stops abruptly.

The 2021 Jeep Grand Cherokee L has has numerous electrical issues. The screens glitch while driving, auto stop start system does not work, back hatch will not close sporadically. These issues are happening to many Grand Cherokee L owners and the dealership says they are "known issues". Batteries have been replaced and issues persist. The electrical system issues are now causing the car to drive inconsistently.

The contact owns a 2021 Jeep Grand Cherokee L. The contact stated while driving at an undisclosed speed, the steering wheel was difficult to turn in the intended direction. In addition, the contact stated several unknown warning lights were illuminated. The contact turned off and restarted the vehicle and the steering wheel independently reset. The failure reoccurred, and the contact stated that the steering wheel seized. The vehicle was towed to the residence. The vehicle was scheduled for diagnostic testing the following week. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 78,300.

Jeep recently pushed an update through the vehicle over the air. Since the update the forward collision disable warning light has been illuminated on the front cluster. All attempts to correct the issue have rendered useless. The update has caused the safety feature of the front collision warning (sound and/or breaking) inoperable.

December 2021 about 2 months after purchasing, traction control, power steering light would intermittently turn on as well as the radio screen would flash black. All of these were separate problems and were not ways necessarily present when another light was on but they did occasionally all happen at the same time. Periodically, not every time when the light came there was the inability to turn the wheel. The length of time the light of inability to turn the wheel would vary sometimes the light would go away after turning the vehicle off and turning it back on while other times it was days. By the time a shop is able to get it in to be looked at the lights were off and not able to be recreated. It was at the dealership for a while and was told I could bring it home. I had concerns the and voiced them that although the light isn’t on now, what if it does turn on and I can’t turn the steering wheel while driving? It couldn’t be fixed if they didn’t know what was causing it. Eventually an ‘update’ was done and supposed to have fixed the problem. The radio still flashes a black screen periodically, the lights didn’t come on as frequent and the inability to turn the wheel went away. Until recently December 2024 intermittent lights that come on but do not stay on, check engine light, electric power steering, front collision (off) and traction control. These lights have come on intermittently but do not stay on. I have had times where I was unable to turn the wheel, luckily not on the road, the vehicle has lost traction while driving in the snow over the winter and has occasionally felt like the vehicle was ‘chugging’ down the road. Now the symptoms are not present every time a light turns on sometimes it runs fine. The length of time the lights stay on vary and again by the time I can get an appt the lights are off and the lights do not always come on at the same time as another. So the issue occurring with hardly any miles and no again with about 50k mils.

Jeep caught on fire in my garage in the middle of the night when it was off, burnt my entire house down, 4 fire investigaters and a forensic scientist, swaid the fire started in the battery compartment.

Sunroom seal flies off without warning. Potential danger to other vehicles on road with flying debris coming off sunroof. The seal has been replaced repeatedly, but continues to happen.

Started my car and all brake lights came on. I had no brakes, brakes wouldn’t pump. Luckily I was a few miles from a Jeep dealer, they said it needed a brake module system, $1100 to repair. I have 56,000 miles and it is not under warranty.
