2021 JEEP GRAND CHEROKEE L Forward Collision Avoidance Warnings Problems

Randomly, and without warning, the instruments, gauges, and displays will switch to Italian along with cluster and radio display settings reverting 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. change to metric 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. The dealer charge me $300 diagnostic fee before resetting the software. Time goes by and it happens again. Dealer says there is nothing they can do and to wait for...

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.

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.

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.

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...

The forward collision warning light came on and will not go off. I have had the sensors tested for recalibration and the test showed that the sensors are working. Light is still on. MOPAR is aware of this issue as there are dozens of complaints in online forums and a STAR online publication has been published by MOPAR Case number:S2108000249

The car updated itself and now my front collision warning light is on, I have tried to reset everything but still on. The update caused the warning light.
