The check engine light keeps coming on it has to do with the emissions control the vehicle does not run properly. It has been in the shop 3 times going on number 4 for the same exact problem. I was told that it falls under the lemon law because the emissions control system is defective in that vehicle. My wife was driving the vehicle with our three month old grandchild and the vehicle would not accelerate would not move at all in traffic on a busy highway with vehicles passing by her at 45 to 50 miles an hour.

While driving 60 miles per hour along the southbound express lane of garden state parkway my new 2020 Jeep Grand Cherokee started shaking. Within seconds, I pulled on to the grassy area next to the fast lane where my vehicle died. After getting towed to the dealership, I was notified that my new car with 329 miles on it is in need of a new engine, new batteries and new starter. Of notable concern on the repair order is the following: "what is present inside intake manifold is pieces of metal." While the case is not yet closed, Chrysler informed me they intend to fix the vehicle under warranty and return it to me. This is a serious safety concern and I fear the blown engine, dead batteries and starter could have caused additional, unrecognized damage.

I was at a red ight, on a busy road. The light turned green, I was the first car stopped in the turning lane. The light turned green, and as I turned, the car into the lane, it rolled foward for a second when I took my foot off the brake, then it lept forward, stalled, then said on the display that the car needed to be put in park before starting the engine. I was in the middle of the intersection going across oncoming traffic.

Wednesday, August 5 2020, was driving about 3 miles from my house when I noticed message on dashboard "place car in park to start car". thought it was odd because I was driving. I then noticed car was off so placed in park (on the road btw) and started it up again. No more issues that day. Next morning, August 6th, car shut down again in nearly the same location. This time traffic was much busier and I was in right lane with cars behind me traveling 45-50 mph and to the right was a merge lane with multiple cars coming over...car slowly glided into the merge lane as everyone became aware I was in distress and allowed me to move over. Car would not restart and was actually locked in park, so I was unable to move car from traffic lanes. Called police and tow truck who brought it to a Jeep dealership. It was a very dangerous situation to be in during early morning commute time. Now its Saturday and I have no communication as to what the problem may be, so I searched some internet and learned this has been going on for awhile with Jeep. I was provided a loaner car by the dealership.

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 using the rear park assist, with my foot completely off the accelerator, the vehicle has spontaneously accelerated while going in reverse, requiring me to hard break to avoid collision. This has happened multiple times.

- Phoenix, AZ, USA

With my foot completely off the accelerator, the vehicle spontaneously accelerates under certain conditions. While in standard or sport mode, in second gear going about 20mph, there is a reproducible RPM surge that causes the vehicle to lunge forward. This somewhat feels like being rear ended.
