There is a thumping noise coming from the rear of the vehicle while in motion. It is getting worse and we are not sure what it is and the service department has been unable to fix it. We are concerned with it getting worse the more miles we put on the car.

The sos button in the car and the assist button in the car don't work. If you push either you get a busy signal. Sos is for emergy help. I took it to the dealreship. After a couple weeks of fca collecting data they finally told the dealership it is a know problem. I have the car back, but, these features do not work. If my cell phone is damage I can not use sos to get help. They said they would let me know when there is a fix.

After only 350 miles my engine started sputtering and had to pull over. By the time we stopped the car the sputtering was violently shaking the vehicle. We had to get it towed only for the dealer ship to take several hours to replace a spark plug. - at almost all time there the air conditioner never seems to get to the desired temperature for more than 20 seconds. When at a stop, the A/C is non existence and temps drop significantly. Unless you have it set to max A/C it will never feel cold/hot. - the transmission is extremely rough at all times, it can jerk you back and forth while it switches gear.

When changing a flat tire according to the directions in the owner's manual, and on a flat surface and using the jack that was included in the vehicle...after jacking the car up to the appropriate height to change the tire, the jack failed and the car fell. The jack was tweaked out of shape. Luckily no one was injured but the jack is no longer usable.

I was involved in a head on collision with a snow plow mounted to a Ford F-250 where significant front end damage was done to the vehicle, and the airbags didn't deploy. There's no way possible these airbags should have not been deployed.

I was slowly backing into a driveway when the Jeep Grand Cherokee suddenly accelerated on its own. I repeatedly hit the brake pedal but the Jeep wouldn't stop; instead it kept going faster. It smashed into the garage door and the brick wall of the garage, demolishing them. The Jeep was brand new with only 500 miles driven, and it was equipped with a complete safety package that should have automatically stopped it before an impending impact but it did not do so. This was an extremely terrifying experience and it felt like a nightmare.
