The Cruise control pacing/follow option does not slow down/break and will rear end/strike any vehicle. The auto breaking does not work. The touch screen constantly cycles randomly changing map directions, radio stations, heat and air conditioning, seat heating and cooling. Puts driver at risk due to constant changes and alert sounds.

Sensors that activate when objects are close to vehicle and are supposed to warn collision do not work at all. Sometimes they activate when there are no obstacles at all and the vehicle is stationary. Pedestrians are not noticed nor are objects/vehicles that are in the way as the vehicle is in motion (and even stationary). Also the system seems to reboot at will while driving.

The Jeep Uconnect System control screen has delaminated form normal use which is a well documented issue on thousands of jeeps from online research. The delamination now has the vehicle pushing buttons on the screen by itself and changing safety parameters while driving. I have a video showing that while I am driving and not pushing any buttons the screen is frantically changing steering parameters, braking parameters, collision avoidance, lane departure, blind spot, etc. I have a video of the incident and screen doing this by itself. I can not upload it due to size, but please contact me for the video and I will send it.

The radio randomly changes every 5 seconds, the beeping will drive a person insane, blutooth will hang up or not allow me to answer or call out. The seat warmers turn on randomly as well and i’m unable to lower the temp or turn them off. A/C in the winter and heat the summer. auto start doesn’t work cuz vehicle shuts itself off after 30s - 1 min and navigation is useless cuz of this electrical gremlin. How long before it accelerates by itself or cuts the engine while I’m on the freeway. Safety HAZARD

I was driving to work with the heated seat on. I began to feel my lower back getting extremely hot. I leaned forward and when I did I could smell something burning and my back began to burn. I quickly pulled over and jumped out of the car as quickly as possibly to see that my seat had physical flame coming from it. I contacted Jeep about the situation and was ultimately told it was somehow not a manufacturing issue. In addition to the seat fire my touch screen has completely delaminated and sometimes works and sometimes doesn’t. Making it a safety hazard with the back up camera only showing when screen is operational. The screen also does things on its own. Changing radio stations, blasting radio volume, turning on/off. This is extremely distracting while driving.

Driving home on dark, deserted roads, my brights will not click on. When I click, nothing happens. When I hold the turner back in the mode to “flash my brights”, the bright headlights will come on. I had to drive holding this back almost an hour so I could see. I had a mechanic look and he said the switch is wired to the computer, so it is not an easy fix, but will have to go to the dealership. This is a safety issue. Dealerships are far from me and expensive. I’ve never had this issue with a vehicle before, when all lights are functioning. It should be recalled and fixed by the manufacturer.

1.At 63263 miles ADAS front Parking sensor and at 96000 miles Active park assist modules are failing with a pop up message asking for a service. The parts are working intermly but, I believe it could potentially mislead the driver when parking using Active Park assist and can cause and injury or damage if the safety system fails. It was inspected by a dealer before but exact diagonisis was not provided. 2. Air Suspension system warning came up at around 96000 miles. I immediatly took it to a dealer who charged 1800+ dollars to inspect and replaced a valve block mentioning C1556 code and said the poblem was sorted. I checked my car and the system warning still exists. They took the car immediatly and kept for 4 days and mentioned the air compressor in air suspension could be weak and over heating causing it to fail. They mentioned there were no leaks on any air bags of the suspension and quoted a 3400$ additional cost of repair. I believe the inital diagonisis was incorrect or not up to the mark (the part is available for inspection) from the dearlership as there were no clear indication of what was the root cause. This suspension failure could cause the ride height to fail any time and can cause imbalance while stopping the vehicle at higher speeds as it has an Aero mode. The air ride system is working intermily depending on the climatic conditions the components are malfunctioning which has to be addressed by the FCA group.
