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.

The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was approximately 40,000.
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.
Driving about 45mph down the road and car in front of me suddenly stops. I immediately hit the brakes and had plenty of space to stop but truck wouldn't stop and brake pedal went all the way down to floor and I rear ended the car in front of me. It wasn't snowing, raining nor was the road wet but it was a cold day. Not sure why it didn't stop looking back on it felt like if there was air bubbles in the brake line which caused a delay in stopping, also remember feeling antilock brakes engaging and automatic emergency stop not braking for me when I was close to other vehicle.

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. …

The Uconnect system laminate bubbles and as such, the system has a phantom buttom touch every few seconds. While driving, this results in an audible ding, the navagation no longer is visible, you are unable to use the backup cameras. I have also been in a situation where it turned on the seat and steering wheel heating and I was unable to turn it off. This is a very wide spread issue and is an incredible safety hazard when driving. It effectively makes it not possible to control the electronics of the vehicle while driving. I urge anyone reading this who does not think this is a huge issue to try driving one of these vehicles while this is happening. I used to drive over 20K miles a year with my previous vehicle. This issue started a month after I bought this vehicle from Vroom. As such, I have driven less than 1,200 miles in 18 months. …
