I bought my 2006 HHR last April and after having it about 3 weeks I have had problems with it cutting off while I'm driving on the interstate, not starting in any kind of weather. It's been in and out of the shop, sometimes in the shop 3-4 days at a time and in the last 4 weeks I've had numerous relays replaced, rotars, battery and transmission gasket replaced. Two weeks ago power steering just all of a sudden went out, some type of fuse, my regular lights and bright lights (that I never use) went out AGAIN, battery replaced, transmission gasket replaced, last Thursday just had the and the crank cylender or cylinoid (however it's spelled) and fuel throttle replaced started up fine on Fri & Sat, went out Sun. morning to go to church, nothing. My husband and I played around with a couple of relays and it started, I turned it off and tried to start it and nothing, later that day it started and it started this morning, but I drive 40 miles one way to work each day, and I don't feel confident in that car; the mechanic at the chevrolet dealer can't seem to find much wrong with it; and I've already paid over $1,000 to it "fixed". It makes a humming noise, always. The mechanic at the dealer, which is very nice and honest told me that I also need 2 tires, struts, and something else I can't remember all of this and I'm still making payments and still have 2 years left, I can't afford to keep fixing it and still make payments. I'm very frustrated and I love Chevrolet/GM I grew up on Chevrolet.
