2006 Chevrolet HHR Owner Comments

problem #6

HHR 4-cyl

  • 130,000 miles


Driving at 70 mph on freeway and suddenly "engine power reduced" warning comes on display and I can't accelerate. The engine cut off. On the freeway. This is not safe (obviously) and I don't see myself buying another Chevy again. I have a family and this problem could kill us all.

Car speeded up and down, car started to spin in circle, lost power steering, lost control of car, flipped and rolled over 3 times down a 30 yd. Cliff. No head air bags worked at all, only the steering wheel air bag worked. Took over 2 hrs. To be found by police. Had to use cell phone signal to be found.

I recently started getting a dashboard message saying "reduced engine power" and the car loses power and will only get to about 10-15 mph. I was driving at round 45 mph when this happened and the car behind me almost hit me because the car slowed down too fast with no break lights until I hit them. Since then it happens randomly a few times a weeks. It doesn't seem to happen while on cruise control so I have been trying to use it as much as I can. I have read forums and this issue and it seems like no one can pin point the exact problem as it can mean a number of different things. I don't have the money to try out all the different fixes for this in hopes that I get the right thing fixed before I spend thousands of dollars. With the number of other people having this problem there should be a recall to at least have the car checked out to pin point the problem free of charge.

HHR 4-cyl

  • 67,800 miles


Drove 1 mile. Turned engine off for 15 min. When restarted car it started shaking, warning message on dash read engine power reduced. Unable to drive more than 30 mph, with car still shaking drove 1 mile to my local mechanic, when mechanic restarted car and conducted dx test and reset code the problem resolved, no further incidents after miles of test driving. Hesitant to drive car any long distance for fear it may happen again and curious if other HHR drivers have had this problem or if there was a silent recall.. would like advice as to how to correct this issue, prevent a recurrence without expensive dealer costs and feel safe driving this vehicle. Please advise. Thank you

The contact owns a 2006 Chevrolet HHR. The contact was driving 5 mph when the accelerator pedal became stuck and the vehicle increased to a speed of 80 mph, despite the brakes being depressed. The failure was resolved when the vehicle was powered off. The vehicle was taken to a private mechanic and the manufacture was made aware of the failure. The vehicle was not repaired. The failure and the current mileages were 62,000.

2006 Chevrolet HHR. Consumer writes regarding accelerator issue the consumer stated when he released the accelerator pedal, the vehicle continued to accelerate. He turned the ignition off and pulled over. After re-starting the vehicle, it seemed normal. Several days later, the incident happened again. The dealer reprogrammed power train control module.
