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 Express Owner Comments

problem #1

Nov 202008

Express 2500 V8

  • Automatic transmission
  • 86,000 miles


I am so frustrated that this is happening, It has been ongoing since 2008. Overheated a few times, didn't realized the thermostat was at its peak and had to pull over.

Now I constantly look at my thermostat, add water regularly, and park my car facing up; this way it doesn't leak as much, I noticed. Oh another thing, my check engine light comes on and turns off and now its on all the time. Obd 2 reader says heater sensor malfunction<<< I hate sensors!!! drives me Nuts. Sensors are nothing but scams for the dealers..
