While driving, all the light on the dashboard come on. When this happens the speedometer is not working the windshield wipers come on. The emergency brake light is on, the car shifts out of gear and the turning signals don't work and the hazard lights won't work. This is all happening at the same time. I'm unable to inform people on the road that I'm in distress because my hazard light won't work I don't know how fast or slow I'm going. I can't inform the people on the road that I want to change lanes. Then after a while all the lights on the dashboard would go out and the check engine light would remain on for maybe two days and than go out. This problem has been going on since January I have paid thousands of dollars attempting to get this problem fixed. My car has been back and forth to the same Chrysler central Ave dealership where I purchased my 2018 jeep grand Cherokee to which I'm still paying for.

The UConnect display on my vehicle is phantom pressing buttons, going to different screens, turning things on and off as I drive. Yesterday, I was put in a EXTREMELY unsafe situation with my vehicle where the UConnect screen turned off my blind spot detection. I was unaware until I attempted to merge into another lane and hit another car!!! I called UConnect and Jeep and they told me they won-??t do anything because I-??m not the first owner of the car and that it can-??t be replaced but for 1,000 of dollars. I feel like this should be repaired by Courtesy because this is a safety issue.

I purchased my 2018 Jeep Cherokee right off the dealership lot in Lynnfield MA in August of 2018. I then have had on going issues. Starting with strange squilling sound coming from back of vehicle, this was never found reason by technician but they replaced engine air filter jume 2020, then my heater wasn-??t working in dec.2020, replaced motor blower with wheel, then may2021 my vehicle just shut down as I was driving on the highway to work at night no prior warnings beforehand, lucky no one was hurt towed in and no start and transmission was stuck no fuel pressure, dtc related and shorted fuel pump. Replaced module fuel pump level unit. Now just October 29,2021 my vehicle is not starting I jumped the battery and lights come on but vehicle won-??t start. Dealership I purchased vehicle from won-??t contact me back so I towed the vehicle to them and still no response. I-??m very disappointed in Jeep I don-??t feel safe or that my vehicle is not dependable and for all the money I keep putting into it I should have a dependable car.

Vehicle unexpectedly accelerated on its own while I was braking. Had I not been breaking, I would-??ve gotten in a car accident. Even letting off the brake slightly caused the vehicle to jerk forward quickly and aggressively until I slammed on the brake again. This is the 2nd time this has happened now.

After wide open throttle acceleration, vehicle continues to accelerate even after letting off of throttle. Had to immediately depress brake to its maximum capacity to slow/stall the unintended rapid acceleration. It has duplicated this behavior twice in the last 100 miles. The Jeep also indicates an error message regarding electronic throttle control error. Once again uncontrolled rapid acceleration after wot!

I was sitting outside of my garage door waiting for it to fully open, I had my foot on the brake and the rpms of my car maxed out and my car went forward through my garage and into my living room. I never once touched the accelerator and tried braking with both feet and my car would not stop. There are burn out marks left throughout my garage where you can see I was holding the brake. My car was completely totaled, my seatbelt also did not lock up during the incident.

The upshifter paddle driver control on my Jeep srt trackhawk, along with many other 2010+ fca vehicles equipped with paddle shifters, performs the opposite function (downshifting) when vehicle is in motion- causing the gears to lower one or more, the engine to rev up, the engine to engine-brake, and ultimately the weight of the vehicle to shift aggressively to the front unintentionally.

On multiple occasions, while traveling at varying speeds, the entire dashboard and infotainment system have shut down for anywhere from several seconds to several minutes. The engine has not shut down, but there has been a noticeable lack of power following these events. This has occurred while maneuvering through a parking lot, traveling on a highway, through a downtown city street and on country roads. The events have occurred at varying times of day and during varying weather climates. The initial occurrence was in June 2019 while traveling on the highway. The vehicle has been to the dealership multiple times for service for this issue, yet the problem continues to occur. They have replaced a backup battery to the start/stop, as well as the button, in efforts to locate and solve the problem.
