2008 Chevrolet HHR Owner Comments

Our car had engine troubles where it kept shifting back into neutral while we were trying to drive on the highway and then on side streets on the way home. While driving it to get repaired, there was a loud popping noise and the engine burst into flames. The flames consumed a large portion of the car.

I could easily complain about the cooling system as this cost me about $1400 this month due to first the water pump going and then a chrome pipe/hose that goes across the engine also rusting through...but because I guess that wouldn't be considered a "dangerous" issue other than possibly being stranded, this engine related complaint is in regards to the exhaust. The car is a 2008 and twice the exhaust "flex" hose which is just beyond the exhaust manifold and in front of the catalytic converters has rusted and developed leaks. Because of the proximity of the part close to the engine, not only do the exhaust fumes rise up into the passenger cabin but it sounds like large diesel truck. The dealer will not replace only the flex hose and will only replace the entire pipe back from the manifold which includes 2 catalytic converters for around $2000. Not only is this dangerous for the driver/passenger inhaling the fumes but it's robbery to the consumer as the car isn't even worth that much.

HHR 4-cyl

  • 142,000 miles
Around April my car started to have a hard time accelerating. A warning cane on the dash that read "loosing enginepower" or words to that effect. When I would brake my car would shake. When I would drive at about 35 my car steering wheel would start B to shake and was hard to control. I took it to my local Chevy dealership where I had the oil change, all four breaks replaced, the tech took a ride with me to hear and feel what my car had been doing. He said he didn't know what it was but ran a diagnostic on it and it said multiple things maybe wrong with, such as the fuel injector, the turbo had came up and a fuel regulator and the electrical system. I asked if it was safe to drive and they insured me it was. My car continued to make all these sounds and struggled to accelerate and the breaks were still slipping. On April 17th I was driving on my son's field trip and suddenly my car started to lose power. I pulled over to side of the interstate at the truck stop. I turned my car off and oil was every where. I had my car towed to the local dealership where I purchased the car. They said the timing chain had broke, causing major damage to my engine. I will have to replace my engine. Had my car been properly diagnosed, this could have been prevented. I am now out I found a vehicle due to this misdiagnosis. I have had this car for almost 2 years.
