2021 JEEP GRAND CHEROKEE L Complaints

Randomly, and without warning, the instruments, gauges, and displays will switch into a language I do not speak or understand (Italian). Coinciding with the switch to Italian language, cluster and radio display settings revert back to default settings, auto door locks and paddle shifter becomes inoperative (with no menu to enable), pedestrian emergency brake (peb) lamp or forward collision warning (fcw) lamp turns on with no way to disable, units of measurement including speed, temperature, etc. all change, and many other random settings change as well. ***This is clearly a dangerous situation because of all the functions and gauges that change, and the fact it is difficult if not impossible to recover from this due to the language of the setting menus, and the complexity of discovering and navigating through all these changes. I have taken it to the dealer twice, and they say there is nothing they can do and to wait for a possible software update, but none has come and it has been over a year. When this happens, even if one is able to wade through all the settings menus and change setting back, some items cannot be reset (like the FCA off lamp). According to various Jeep owner forums, some dealers have been able to reset something and temporarily correct the issue, but they charge for this service, and the issue returns randomly again. Here is an example forum discussion, indicating many if not all vehicles are affected: [XXX] Many people on the forum believe this issue did not start until a software update a year or so ago. This is a well known and widespread problem, and there is even a DOT Bulletin on the issue: dot.report Bulletins Because this is dangerous (for settings/gauges/units to no longer be useful while driving), and it occurs randomly, I strongly believe this issue should be a manufacturer recall. I am available for any needs. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2021 Jeep Grand Cherokee L. The contact stated while driving 70 MPH on an interstate and depressing the brake pedal to avoid a crash, the automatic emergency braking system suddenly engaged, and the vehicle experienced a drivetrain failure. The contact was able to pull over to the side of the road. There was no warning light illuminated. The vehicle was towed to the local dealer, where it was diagnosed that the drive shaft, the transfer case, and the drivetrain control module had failed and needed to be replaced. The drive shaft was replaced, but additional repairs were needed. The vehicle was not repaired. The manufacturer was notified of the failure, but the case was closed, and the contact was referred to the dealer for assistance. The failure mileage was approximately 93,000.

The vehicle has twice gotten stuck in third gear. While driving, as it's shifting from third to fourth, will get stuck in third and clunk, and then rev. The engine light will come on, and it forces you to pull over. The manual shifters do not work either. You have to pull over, shut the car down, and restart. The engine light comes on but no errors are logged, and the engine light clears itself a few restarts later. The first time this happened to me, I was driving with my son and it startled us that the car didn't seem to go but revved high. The most recent time, July 18,2025 I took pictures. My whole family was in the car, and we were driving through a campground with people walking around. I didn't have time to make a decision to pull over. There wasn't anywhere safe to park, so we had to coast bit to find a spot.

There were no warning lights, but when I got into car I seen my passenger seat swollen up. Looks like lumbar expanded and is going to pop. Could be dangerous if it explodes to the person sitting in the seat or behind. It just happened out of no where.

Was accelerating to pass another vehicle and all of the sudden the the check engine light came on and the engine started shaking as if it were shutting down. I was able to slow down and pull over on the side of the road. Now I am unable to accelerate over about 30 mph without this occurring.

[XXX] approx.[XXX], while driving my 2021 Jeep Grand Cherokee on [XXX] the Jeep without any warning sputtered and stopped in the middle of traffic. I could not get the car to keep running, and finally wouldn't start at all. I called the Sarasota Sheriff's Dept who came to the scene and found the situation to be dangerous to my vehicle and others using [XXX] they towed the vehicle to Sarasota Jeep on South 41. Received a call from Jeep on July 14, 2025 they advised me it was the Fuel pump integrated Power module which led to the stalling and eventually preventing the Jeep from starting.

High Beam Headlights not working on Auto mode. Was inches away from Hitting a deer due to the high beam headlights not working. This would have been a very serious accident and I had my toddler in the car with me..... Same vehicle models have a recall for this, Recall is --- NHTSA Recall 21V-797, also known as Recall Y66, involves Chrysler (FCA US, LLC) vehicles due to a potential issue with difficulty activating high beams. The recall was issued because the high beam activation mechanism may not function as required by Federal Motor Vehicle Safety Standard (FMVSS) No. 108 S9, potentially reducing visibility for drivers. The National Highway Traffic Safety Administration (NHTSA) notified owners about this recall on October 28, 2021... Part Number - 68374988AA... Vehicle is 2021 Jeep Grand Cherokee L Laredo 4x4 3.6L V6..... Dealership service will not service this since there isn't a recall shown for my Jeep vin specifically. Even though there are identical models that have this recall. Jeep Dealership wants over $900 just to check and maybe service this issue..... This is a very serious issue. I have already scheduled an appointment on 7/18/2025 to have 3 other recalls fixed at this dealership and would like to ask for you to please have them service this issue as well since this is an oversight on the manufacturers end..... This high beam issue was caused by an oversight during vehicle programming, affecting "Body Controller Modules" with part number 68374988AA

I just discovered my IPC module is faulty and has been faulty. My vehicle has been putting itself into park while driving multiple times now in the little over 2 years I’ve had it. Along with many other electrical issues (power steering going out) engine not cutting off after putting it I to park and cutting the jeep off. Dash going out. Biggest issue is my vehicle causing me near miss traffic accidents. The dealership it was purchased from, certified. Hid service history reports at the sale. Also returned this vehicle multiple times without acknowledging the issue or even telling me they didn’t repair the issue. Last time it was picked up from Matt Bowers Jeep in Baton Rouge within 30 mins the issue was happening and more (rpms shooting up and Jeep taking off without giving it gas). I went public and another dealership reached out to help me. Within a few hours they noted that the vast majority of my modules weren’t updated, some bad and the IPC module keeps failing. They’re working with Stellantis trying to troubleshoot the issue. This has never been made known by Matt Bowers and matches the original service records hidden from day one. I cant get my vehicle back while the IPC module is faulty because it’s a serious safety hazard. Matt Bowers has put me back I to This vehicle multiple times knowing it was a hazard and I even Stated I felt unsafe in this Jeep. This is a serious safety hazard!!! Mopar was also made aware and has never returned any messages.

2021 Jeep Grand Cherokee L. I was idling at a light, which means the engine had auto-shut off. The light turned green and I stepped on the accelerator. Car kicked back on like normal and I got back up to speed ~45 mph. So now I'm about 1/4 mile past the light and I hear the engine kick off and lost all acceleration (everything else was normal). Warning popped up on the dash that "vehicle is not in park". I put on my hazards, braked to a stop, put the vehicle in park (nothing happened), hit the push button to turn the vehicle off, waited 2 seconds, hit the button again to turn it back on. It restarted.
