Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2007 Chevrolet HHR Owner Comments

HHR 4-cyl

  • 110,000 miles


Proceeding at normal speed on hwy 14. The check engine light illuminated followed by an illumination of the traction control light. There was a loud pop sound emanating from the front the vehicle. At this point the engine stopped running and I pulled to the side of the road. The vehicle was already on fire by the time I reached the side of the freeway. By the time I was able to exit the vehicle the engine compartment was fully involved in fire and within a matter of two or three minutes the remainder of the vehicle was engulfed in flames. I did notice other Hhrs have been on fire as shown on the internet and the adjuster stated HHR fires are common. I barely made it out of the car.

The contact owns a 2007 Chevrolet HHR. The contact stated that the speedometer displayed incorrect readings, the steering wheel would become difficult to turn, and the vehicle would stall. In addition, the check engine light would illuminate on the instrument panel. The vehicle was taken to an authorized dealer and they were unable to duplicate the failure because the failure occurred on an intermittent basis. The failure and the current mileages were 43,000.

  • 99,000 miles
The contact owns a 2007 Chevrolet HHR. The contact stated while driving 70 mph, the check engine light illuminated and the vehicle stalled. A message comes across the instrument panel saying motor power reduced; motor shut down. The contact was able to pull to the side of the road and restart the vehicle. The contact took the vehicle to a local mechanic and was diagnosed as having a faulty throttle body. The mechanic replaced the throttle body, but, the repair only remedied the stalling temporarily. The vehicle continued to stall so the contact called the manufacturer. The manufacturer informed the contact of a GM recall for the PCM, but her VIN was not included in the recall. The contact stated the vehicle was unsafe to drive. The failure mileage was 99,000.

HHR 4-cyl

  • 11,604 miles


It would be easier to list the things that are ok with this car. I've resurfaced or replaced the rotors several times (four times in one year) after consistently complaining to the dealer that it sounded like things were falling off the car. The car's braking and steering capacity is extremely diminished. I've replaced a broken stabilizer control arm and now I'm told the front end needs to be rebuilt. This damage is a direct result of the continuing problem with the rotor warping. The check engine light is on more than off and its been in at least 10 times for this issue. GM customer service is aware of these issues and refuses to return customer calls. Updated 11/29/11. Updated 12/06/11.

  • 90,000 miles
The contact owns a 2007 Chevrolet HHR. The contact stated three months after purchasing the vehicle it would not start. The vehicle was towed to a local repair facility where she was advised they were unable to make repairs. The vehicle was then towed to a different repair facility where the mechanic advised the ignition would need to be reprogrammed. She would also need a new key that would also have to be reprogrammed. The repairs were completed at the contact's expense. On her drive home, the contact smelled something burning and there was a loud pop. She was able to make it to her residence and when inspecting the vehicle, she found that the engine fan had been tampered with. The dealer advised that both the fan and radiator would need to be replaced at her expense. The failure mileage was approximately 90,000. The current mileage was approximately 90,100.

I bought a 2007 Chevy HHR in Jan 07 in el dorado ar, I drove to el paso tx within a month of buying it, the day after arriving I was entering the freeway and the car stalled (1000 miles on odometer) after 10 mins I was able to restart. Had no other issues until moving to guymon ok, in Nov of 08 ABS light came on and enroute to the dealer to have repaired, it stalled as I was approaching a stop sign, and same as 1st time, after 10 mins or so it restarted, dealer stated it was probably bad gas, dealer added a fuel additive and reset ABS (10801 miles) on Feb 24 2009 as I was approaching a stop sign the vehicle once again died (17717 miles), waited 10 mins and restarted, dealer stated it was clogged injectors and cleaned them. On May 11th, 2009 the vehicle once again stalled when approaching a stop sign(18136 miles), after 10 mins restarted. The dealer this time stated it was loose fuses, and a loose battery cable, all were retightened the dealer kept the car for observation for 16 days, on July 6th the same thing happened again while approaching a stop sign the vehicle stalled (19375 miles) and restarted after 10 mins, the dealer stated that it was the cam shaft sensor, and replaced it. On Sept 17 2009, while driving down a major hwy slowing for a curve the vehicle stalled after coasting safely to the side (20215 miles), the vehicle would not restart for 20 mins. Once again took vehicle to the dealer who has no idea what it could be. This vehicle is starting to do this more and more often and in even more dangerous situations, my wife who was the primary driver for the vehicle will no longer drive it as she is fearful for the safety of our children and herself, as well as those who share the roadways with us. This is a serious problem and needs to be addressed immediately.

My car stalled on the train tracks on 10/05/08. Lucky it started right up. My car is not the only one stalling when are you going to tell GM to recall the car. If it was just my car doing it but it is not. Look on automotix, and just look up Chevy HHR car stalling. They need to evaluate what is causing this problem. It seems that GM and nhsta don't care and not trying to see what the problem is. What has to be done to get a car recall>
