problem #4

In April 2007 my check engine light came on. I brought it to the dealer to have it checked out and they advised me it was a bad sensor and changed it. This happened several more time over the next few months every time the sensor was changed. Problem persisted again in Jan 08 car is back at the dealer again 5th time for check engine light this time I was advised when doing the diagnostic check they got a code for a miss. The mechanics could not figure out what was causing this code to come up. The dealer contacted Chevy's technical help dept and did a thorough diagnostic check to find out that the miss was caused by one of the heads going bad...... the car had roughly 15,000 miles on it and the motor had to be pulled and repaired. My car ran great for a while after it was repaired. Now 3 months later and 19,300 miles on the car it started sputtering and the check engine light is back on again! I have never had so many issues with any of the 4 other Chevy's I have had. I feel this car is a lemon and a danger to drive.

HHR 4-cyl

  • Automatic transmission
  • 9,505 miles
Car has died several different times and has been in the service department 5 different times, and service tech's can't diagnose a problem, nor can they duplicate the problem, so I'm stuck to drive a car that is not safe, dying in the middle of traffic, even on interstate.

  • Automatic transmission

: the contact stated while driving at various speeds the engine lost all power without warning four times. The vehicle was safely pulled off the road each time. On three occasions the vehicle restarted immediately when it was put into neutral; on the forth occasion the vehicle sat for 45 minutes and then restarted while in park. It was taken to the dealer after each failure. The dealer installed an event data recorder in the vehicle to be manually started in the event of a failure. The edr did record the fourth failure however was unable to duplicate and repair the problem.
