2021 Jeep Grand Cherokee L problems

UNKNOWN OR OTHER

The hood will pop open while driving. There is a safety catch so it won't open all the way but it urges you to get off the road. This has happened 3 times to me already. The last time was 8/4/26.

ELECTRICAL SYSTEM

A vehicle was purchased at McLarty Daniel Chrysler Bentonville, AR. The sales department had a third party install a non-oem windshield. Dealer attempted repairs, but the records show discrepancies of statements and record. The dealer ignored the instructions to recalibrate the windshield, though the receipt stated “elevated risk of collision” if not calibrated. The owner had on going issues that service should have connected to the windshield and calibration. The windshield of this vehicle has immense safety features that were ignored. The liability to willfully hand over the keys of a known unsafe vehicle is high. The dealership sent a repair request to warranty, only to be denied for “faulty or negligent install” then the service department said “long story short sales will cover the repair” after requesting formal warranty communications did the owner become aware on 7/30/26 and start the process of correction.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

When a car in front of me is slowing down while the adaptive crusie control is on and I have the distance set to 3 or 4 lengths, the farthest one available, and the adaptive cruise control is set, the car will start slwoing down like the cars ahead of me and if I switch lanes to go around of the car that is slowing down and there is another car in front of me of the lane I move into that adaptive crusie control acts as if there is no car in front of me in the lane and will begin to accelerate until I engage the brake. So for example I'm traveling in the far right lane of a four lane road, two going north and two going south. I have my adaptive crusie control on and set to 50 MPH and the distance set to 4 car lengths (max) and then the car in front of me starts to slw down. The adaptive crusie control will adjust and start to slow down as well. So I decide to get into the next lane over to my left, where there also happens to be another car 1 or 2 car lengths in front of me, the adaptive crusie control will not detect that car after lane change and will begin to accelerate back up to 50 MPH when it should still be slowing down to avoid a collision. This has happened multiple times.

SEATS

Passenger seat will always become inflated and will not deflate at times. The vehicle is shut down and seat is properly deflated, overnight it will return to inflated. This seems very unsafe for any passenger.

POWER TRAIN

I brought my 2021 Jeep Grand Cherokee L to the dealership for its scheduled ~40,000 mile service. During that visit, I specifically reported that something felt off with the transmission/drivetrain. The dealership inspected the vehicle and stated that no issues were found. Approximately one week later, the vehicle experienced a sudden and severe drivetrain failure. While driving approximately 45 mph on a surface street and accelerating to cruising speed, the vehicle began shaking violently. There were loud mechanical noises from underneath the vehicle consistent with components coming apart. At the same time, the vehicle lost all ability to accelerate. Pressing the accelerator produced no forward movement. Due to the loss of power, I was forced to coast out of active traffic and onto a side street where I was able to safely stop. The condition was sustained and the vehicle was not drivable after the incident. When attempting to assist the tow truck driver, I shifted the vehicle to drive and pressed the accelerator. The engine revved but the vehicle did not move. When shifting back to park, the vehicle displayed an error message: “Cannot shift to Park, vehicle moving too quickly,” despite being stationary. This failure created a safety hazard due to loss of acceleration and unpredictable vehicle behavior. This is particularly concerning because a drivetrain issue was reported during a service visit shortly before the failure and was not identified. There were no warning lights or messages prior to the failure. The issue occurred suddenly and without advance indication. The vehicle had recently been serviced and cleared by the dealership despite a reported drivetrain concern. A failure of this nature at speed could significantly increase the risk of a crash, depending on traffic conditions.

UNKNOWN OR OTHER

In May 2025 the vehicle randomly, and without warning, the instruments, gauges, and displays switched to Italian, changed to Metric, and we got the update and FCW Off light stuck on. Numerous other settings had been reset. Took to dealer and had to pay for the fix - they noted a STAR bulletin on my invoice. Then this past weekend (May 2, 2026) it happened again. At least this time it didn't go Italian and Metric on me, but lots of other settings were changed. Did not test the paddle shifters but will do that soon. Current software version says FCA-MY24.U29.42-PROD. I've seen other posts with a newer version - not sure if / why not on my Jeep yet.
