A D V E R T I S E M E N T S

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.

problem #3

Feb 032020

Grand Cherokee 6-cyl

  • 350 miles
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.

problem #1

Grand Cherokee

  • 350 miles
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.
