Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2007 Chevrolet HHR Owner Comments

problem #1

Oct 192006

HHR 4-cyl

  • Automatic transmission
  • 249 miles


Purchased 2007 HHR new in October 2006. With only 249 miles on the car, I returned to the dealer and reported a loud banging noise from the drivers side front end. The could not verify the noise. Since then they replaced two shift assemblies, one steering column and in November 2007 they replaced the drivers side front strut. The banging noise was still there. Now they think it may be the chassis tweaking, but still cannot find or fix the the rattling noise. Also the transmission makes a clunking noise and the car surges when starting it while still in park. The say this is normal. My car has been in courtesy Chevrolet's shop for moore than 30 days since I purchased it. I do not drive it anymore as I believe it is unsafe, and a lemon. The car now has less than 15,000 miles. The car was taken to their shop on 10/19/06, 1/08/07, 7/19/07, 10/27/07, 10/22/07 and 11/13/07.
