2007 Chevrolet HHR had a catastrophic engine problem. The master cylinder was not supplying combustion to the third valve of the four valve engine. Which meant no remote control start, it sounded like a diesel engine and the gas mileage had dropped from 32 to 24 miles per gallon.

HHR

  • 23,340 miles
Driving home from work my temp light came on & my car started shaking really bad. While driving it cut off & I had to coast to the side of the road. My car never cranked bk up & had to be towed. There was also coolant leaking from the bottom. Come to find out there was a defect in my radiator because there is nothing covering it (others may want to check into this). I had to have a new engine put in my car in addition I had a faulty wire to my alternator & had to have both stabilizer links replaced about 4 days after the 1st repair. Now when I drive my steering wheel shakes so this will be the 3rd repair.
