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.

2004 Chevrolet Impala Owner Comments

problem #2

Jul 232012

Impala 6-cyl

  • 97,000 miles


Vehicle stalled out / stopped while traveling down the road. It has done it twice now. This car is fully equipped with cruise control and traction control. After the first time (three days ago) we took it to a dealer and they could not find any code (s) and or replicate it. It just happened again today. Both times the car started right up. This could be a disaster at high speeds on an interstate. Thank you. The consumer stated the vehicle stalled for a third time. The dealer ran it for codes and immediately, it came back as a problem with the mass air sensor. It was replaced and so far, there have been no more problems. Updated IVOQ 08/01/12

problem #1

Impala 6-cyl

  • Automatic transmission
  • 87,550 miles
Vehicle has been stalling intermittently at any speed. Vehicle has stalled a total of ten times. The vehicle has been taken to the local mechanic shop five times and the dealership twice but no codes were found during testing. So far I have had new plugs/wires (tune-up), new coil pack, new ignition module and new crank sensor, and new fuel filter. The vehicle completely dies at any speed. Told possibility of bad fuel pump but dealership cannot be 100% certain this will fix the problem. While driving at 70-75 miles an hour the car completely shuts down. It is a miracle I have not been severely hurt or killed. Problems began in May 2007 and have been ongoing since then.
