2006 HHR - 50,164 miles - engine and dash shut off while driving with normal highway/weather conditions and speeds of 65+ mph after hitting bumps/transition points of pavement in the road. These bumps are pavement that sometimes buckle in the summer. The car would still have steering and brakes, but no dash lights or turn signals. No dummy lights illuminated, no warnings came on. The hazards worked fine and the radio was still on. The car would restart on the shoulder of the tollway but he first incident caused the transmission to shift hard and almost shut the car off when coming to a stop. The car was driven to its destination and shut off. Upon the next restart which was approximately an hour later, the car shifted fine. The local Chevy dealer took the HHR in and performed many diagnostic tests and checked numerous electrical connectors and all was fine. The very next week, during a pouring rain, the car again shut off after going over a bump on the tollway. Again, no dash lights came on, the dash shut completely off, the engine shut off, and the wipers stopped, all while traveling at highway speeds in a thunderstorm. The car was again pulled safely to the side of the road and restarted. A mile or two down the road, the same thing happened again. The car was again pulled to the side of the road in rush hour traffic and during a thunderstorm! the car was once again restarted and able to get off the tollway. Calls were placed to two different Chevrolet dealers in the area - one had no power because of the storm, and the others service department had just closed. The rest of the drive home was done on secondary roads at slower speeds and plenty of shoulders to pull off onto. This car is driven daily 60+ miles on the Illinois tollway.

The contact owns a 2006 Chevrolet HHR. While driving 20 mph over a hole or dip in the road, the entire vehicle stalled and shut off. The weather was not a factor. The stalling occurred at least three times within one week. The vehicle cannot be restarted once it shut off. There were no warning indicators prior to the failure. The dealer does not know the cause of the failure or the remedy. The failure mileage was 53,000. The consumer stated the vehicle was having several issues with the cam sensor, wheels, a broken hub bearing, bent rotors and an issue with removing the key from the ignition, due to the shift cable not staying secured. The check engine light illuminated, the inside driver door handle would not open the door, the passenger side back would not stay secured. Updated 06/25/08
