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 Isuzu Ascender Owner Comments

problem #1

Ascender 4WD 6-cyl

  • Automatic transmission
  • 8,000 miles


The headlights dim 2 - 3 times daily while driving. The day time running light is on when this occurs. On 3 separate occasions headlights totally went out for a short period of time before coming back on. Dealership replaced the ignition switch, alternator, and battery an attempt to correct the failure. However, the failure recurred. Manufacturer refused to do any more repairs unless the dealership was able to duplicate the problem.
