“As I turned into a gas station after driving highway speeds, the vehicle stalled out. I lost power steering and brakes. The dash began flashing put vehicle in park to start. I had to come to a complete stop, place the vehicle in park and then restart it. The vehicle has approx 3800 miles on it with a fresh oil change from the dealership, frontier dodge. After restarting, the vehicle ran fine.”

“I drove this vehicle to work and parked it in a parking structure at 8:00 in the morning. By 4:00 in the afternoon, the vehicle was engulfed in flames. The vehicle sat all day in the structure. Unknown as to why it caught fire, but the fire originated somewhere in the engine compartment. I took delivery of this vehicle 8 days before this happened and it only had approximately 300 miles on it.”

“2018 Jeep Grand Cherokee trackhawk throttle stuck open and began accelerating after removing foot from gas pedal. This issue is not related to the floor mat recall as I have already had the recall performed on the vehicle by the dealership. This could have caused a serious injury or death. I had to press the ignition to turn the power off and slam hard on the brakes to stop the vehicle from continuing to accelerate.”

“Vehicle losing coolant due to faulty water pump. Under normal driving conditions, the water pump does not hold up to normal vibration and use. I have taken it to a repair shop and they notified me that the water pump was back ordered and we were number 300 in line for a replacement. It is hard to believe that 300 people are waiting for the same water pump if there is not an issue. That is not including the number of stock that Jeep has already sold to be in back order.”
