2021 Jeep Grand Cherokee L

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.

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.

My vehicle was experiencing the exact same HVAC/AC issues described in Customer Satisfaction Notification Z33 for the 2021 Jeep Grand Cherokee L. Although the campaign specifically lists my make, model, and year, Stellantis claims my VIN is not covered. I was forced to pay $175 for the same repair listed in the Z33 document (HVAC module flash, Labor Code 18-Z3-31-82), and this should have been covered. Stellantis is refusing reimbursement even though the issue and fix are identical.

My Jeep over the last year has automatically put itself into park while I’m driving down the highway! I’ve had near miss accidents due to this. No warning lights, no signs something is wrong. It just either slams itself into park and locks up, then won’t turn off. The last times without warning my engine shuts off, my screen pops up saying put into park to start engine and the vehicle puts itself into park automatically. It’s happens fast to! I was swerved by other drivers each time. Jeep will do NOTHING about this! My power steering goes out randomly also. This has happened more than once since the end of 2023! I’m now scared to drive it.

May 16,2025 my power steering light came on. I checked the fluid, and when I turned it back on it was gone. The next day, I started driving all my safety lights in dash & mirrors came on. When I pulled into my kids school it made a strange noise. I then drove right across the street to Lees tires. When I got there my power steering has completely quit working. They now saw my rack & pinions are broken & need replaced. I am now without a car until it is fixed

Presented as camshaft position sensor with loss of power, poor acceleration and general misfires. After many weeks of diagnostic and repairs, turns out to be a problem with the camshaft intake. Specifically the entire cam kit. Appeared 1 week after purchase as a check engine light. This problem had been confirmed by the chrysler dealership where I bought the car and sent it for diagnostic. Problem with the cam could result in sudden loss of power while driving/and or limp mode. Damage to transmission and other parts such as timing chain. I do not have any invoices, however this vehicle was in for service at greenwood auto in cortland ohio for a week before being transferred to Mig chryler in bellafontaine ohio where it was bought for service. Currently no invoice for the repair because the parts are not available due to high amount of demand for this specific problem. My jeep has now been in the shop for 4 weeks with no timeframe for parts.

The vehicle didn’t automatic update of its “UCONNECT” system without warning after stopping at a gas station. Once the vehicle was turned back on after the update was completed there was a light on my dashboard signaling that the forward collision warning system is off. Some other things happened as well such as all my settings were reverted back to factory settings, and the menu screen was in Italian. After online research, it seems that this is a very common problem with the specific model. I was able to revert everything except for the Ford Collision , warning, which still states that it is OFF, after the update. After communicating all this information with Jeep, they want me to pay for a repair that was due to their system update.
