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.

2003 Chevrolet Monte Carlo Owner Comments

problem #2

Dec 232009

Monte Carlo

  • Automatic transmission
  • 89,000 miles


The thermostat was fixed at no charge along with valve cover gaskets and adding new coolant. I had some other things done as well but for the life of me can't remember what they were the total bill was about $600 bucks and they had my car for a day. It was then I noticed that my heat worked like it should.

problem #1

Oct 312009

Monte Carlo SS 3.8L V6

  • Automatic transmission
  • 71,632 miles

So, now it has been 9 months and i need the heat and i turn it on only to find out it doesn't work! i am at the dealer again. now my gaskets are leaking and they replace the pipe assembly (mind you this was just done in February 2009). The dealership calls to inform me that they will not charge me for these things as long as i replace the thermostat which cost me 138.00. At this point things are getting terribly rediculous.
