“After turning into a parking lot and VERY slowly turning right to enter a designated parking space my 2014 Jeep Grand Cherokee suddenly, with no warning or prompting, highly accelerated forward causing the Jeep to jump up over the curb, ran over a bush which lifted the left side front tire off the ground, continued high acceleration forward making an immediate and abrupt stop colliding into an eletrical power pole at the right front end, both airbags deployed. This happen in a moment's time with no time to react, distance from acceleration to impact with electrical pole approximately 12 feet. No passengers, the driver received contusions and abraisions. 911 was called, local city police responded & report written, Ambulance called to assist injured driver, tow truck transported Jeep to requested Body Shop, Insurance company notified. Jeep released from Body Shop transported by Insurance Company for Inspection. Had the accleration not stopped due to collision with power pole the vehicle would have entered and crossed a 5 lane main street against traffic directions at a stoplight which could have resulted in many collisions and injuries to other motorists.…”

“While maneuvering in a parking garage and switching between reverse and forward, the engine suddenly and unprompted revved excessively, sounding as though the accelerator pedal was floored. The vehicle forcefully lunged forward against braking pressure into a cement wall, causing front-end damage to the vehicle. Cruise control was completely disabled and no check engine light or warning indicators illuminated on the dashboard. At no time did I feel like I had control over the car. I sustained some contusions. No one was in the vicinity at the time; however, other cars and/or people could have been struck. The vehicle has yet to be examined by anyone although I am in the process of arranging for an autobody repair shop. Prior to this, the car was in its usual state of health without any issues.”

“My Son just bought the car from a private party. On our way home the engine light and a lightning bolt icon illuminated on the dash, followed by the vehicle going into limp mode. We had the vehicle scanned for codes and it came back with P0336 (crankshaft position sensor performance). After much investigation online, we found out that this is a known issue with the crankshaft position sensor and, most importantly, the tone wheel on the back of the engine. We looked up recalls on the vehicle and found a safety recall had been issued. While some vehicles affected received replacement of the tone wheel and sensor, others just received a software update. This particular vehicle received the software update. The issue is that the magnetic material on the tone wheel delaminates from the tone wheel. This is a costly repair that should have been fixed correctly from the beginning, not just a software patch. It is a safety concern because it is dangerous when you are traveling at highway speeds and it goes into limp mode.”

“6 months ago, I was driving on the interstate and the ESC system light came on, the vehicle lost power/ability to accelerate, and would only allow acceleration after pulling over and restarting the car. This happened several more times on the interstate, and when the ESC system kicked in it would suddenly lurch the car down about 15 mph and leave no ability to accelerate, causing near collisions at high rates of speed. After eventually taking it to the dealership, it turned out to be failed lifters on the driver's side cam shaft, a known design issue that has apparently plagued the Pentastar engines. This all happened in spite of meticulous maintenance and no warning signs from the engine whatsoever. How is such a significant, known design defect that causes such dangerous driving conditions never been flagged for a recall?”

“My instrument cluster (where the speed, gas level, engine temperature, etc. Is displayed) had completely blacked out. It was periodically coming on. But it's not coming on at all anymore. I've taken it to the dealership, had it replaced (with a used part), had the wiring checked, also tried reprogramming the instrument cluster. Nothing has worked. There was a recall for this same exact problem, with the same exact vehicle except my vehicle was manufactured 3 months after the recall notice called for vehicle manufactured through Aug 2013 my was November 2013. I feel that my vehicle also should've been part of that recall notice.”
