“Vehicle would not restart and left me and my family stranded 1.5 hours from home and was towed by dealer. Once I got it back there were several other problems that I had faced before that were now occurring again. The sliding doors malfunctioned about every other day. The vehicle has given us trouble starting on two other occasions ,as well. These were not reported as we assumed that being a brand new vehicle that we must have left a light or something on. We knew that the problemwas with the vehicle and not our negligence.”

“It is probably a shorter list to list what we haven't had trouble with , but here goes. 1. The back power sliding doors will open and shut at will. Driving down the road, parted in the grocery store parking lot, etc. The neighborhood kids regularly come over to tell me my doors are open. My husband almost missed a flight because he spent to much time trying to fight with the door to stay shut. They have replaced almost every part of the doors several times, but was told by the dealership that last time I took it in they didn't know what to do now. 2. Door locks will lock and unlock at will. …”

“The check engine light has been illuminated as well as the traction control light is on (indicates ABS needs to be serviced) also transmission slips when moving forward. At times when both the engine light and ABS light are on the engine will reduce power. Transmission was replaced at 63,000 for the same thing! Have had to numerous shops who cannot locate issue. The doors will not lock shut- they come forward and pop out and reopen. Must operate manually.”
