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

Jan 252008

HHR 4-cyl

  • Automatic transmission
  • 10,565 miles


I own a 2007 HHR (mileage 10753). It is easy to drive, is roomy and economical to operate. I had a very scary experience last evening while driving the HHR on an expressway in traffic. The motor shut off completely. The lights, radio, etc continued to work properly. The warning message was "engine power reduced". I made it to the side of the road. The car would not restart. No sounds, clicks, nothing. I waited a few minutes and the car started with an engine warning light on. I got off the highway and had something to eat. I went out and the car started up without an engine warning light. I took it to, holler Chevrolet (winter park, fl), this morning. Holler Chevrolet replaced a chip (PCM) and said it would be fine. Mike laing at holler represented both GM and holler with professionalism, skill and dignity.
