Four problems related to check engine light on have been reported for the 2009 Chevrolet HHR.
I was driving down the highway and all of a sudden the service airbag warning light came on as well as the warning chime. I purchased the car used in August 2013, and soon after getting it the very same warning came on. I went back to the dealer and they had it sent to a local gm dealer to be fixed. I purchased the car from a Dodge and Subaru dealer and they were not able to do the repair. I was shown the repair paperwork stating that a faulty airbag sensor was replaced. Well just last week the very same thing happened again. The service airbag light comes on then goes off sometimes after only a few seconds. Then another warning light went on stating faulty air pressure sensor. The check engine light is on as well so I'm wondering if there is some type of electrical gremlin in the car. This is extremely frustrating because I like the car but all of these stupid little issues make me want to trade it in, and never buy anything made by gm ever again.
The electrical system in the car has shut down and has caused my power steering to go out while I am driving. It dings so I have some notice. But none the less really scary and very hard to turn going 20 mph. My brakes are very hard when this happens. My thermostat/ coolant information is currently displayed as dashes (----) across my dash, making this really difficult to know if it is hot or has run out and my ac is connected to this also so when it decides to work my ac will work. It will turn off and on while driving too. My mph reads my speed going 20 mph over what I am actually driving. My car has completely shut off while driving. The check engine light comes on and off making it more difficult to get codes.
While driving on the highway my service esc light came on along with the road traction picture and my car started jerking and shaking after a few minutes my check engine light came on. My husband thought it was misfiring so he changed out the spark plugs but it is still doing the same thing. The esc light will go off for a few miles but will came back on.
The contact owns a 2009 Chevrolet Hhr. The contact stated that he had several problems with the vehicle. The failures included the brakes, power steering assist and a foul odor being emitted through the ventilation system. In addition, the driver¿s side door handle cable fractured and the check engine warning light was illuminated on the instrument panel. The contact stated that he took the vehicle to the dealer for the failure of the power steering assist where they advised that the steering rack needed to be replaced. The steering rack was repaired but the failure recurred. The vehicle was then taken to the dealer because the check engine light was illuminated and they advised that the cam shaft sensor needed to be replaced. The vehicle was repaired but the vehicle began to drive roughly afterward. The vehicle was also taken to the dealer for the brake failure, door handle and the exhaust and the technicians stated that they could not duplicate the brake problem or the foul odor that was coming through the exhaust. In addition, the cable in the door handle needed to be replaced. The manufacturer was notified but provided no assistance. The failure mileage was 32,000.
