2008 Chevrolet HHR Owner Comments

problem #6

HHR 4-cyl

I took the car into the shop on 11/15/14 because of a loud exhaust sound. The mechanic advised the flex pipe was leaking and the flex pipe and catalytic converters (2) would need to be replaced. The cost is estimated at about $900. If the car is in idol, the exhaust seeps into the car and could cause carbon monoxide poisoning and death, if the windows are not cracked to allow for ventilation. Unfortunately, we cannot afford this repair at this time. The car is 6 years old and should not be falling apart piece by piece as it has been over the last couple of years. This part should be recalled, or should I say the entire car, B/C it has had so many recalls in the last couple of years.

I purchased a 2008 Chevrolet HHR in may of 2009. The vehicle has overheated 4 times in a year. The radiator and cylinder heads have been replaced and I can not be guaranteed that is will not happen again by the dealership. They have admitted it is an unseen situation, but they are unable to resolve the issue.

I also own a 2008 Chevy HHR lt that is loaded. I purchased this vehicle brand new and currently have 39,000 miles on it. I have had nothing but trouble with this vehicle. I have had all of the following problems and GM replaced some of them. GM installed a new intermediate steering column, drag links, turned rotors 4 times and right side upper ball joint. After the warranty expired, the brakes once again went to hell in a hand basket. I ordered a set of racing rotors and ceramic brakes, this cured the brake problem. At 37,000 miles, the check engine light came on and I had it checked out and it was the cam sensor. I replaced the sensor and reset the light and it did not fix the problem. I really like the vehicle, but GM needs to do their homework and do more research and development.
