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.

Service bulletin or recall 2003 Isuzu Ascender. Problem key stuck in the ignition can not remove seems to be normal problem for this make and model. L have been reading through forum complaints on the internet. I am curious if there has been a recall and if not why not. Car could be car jack or stolen by not able to remove the key from the ignition. This has been a intermittent problem.

Heater/ac fan kept going out. Was told it was relay switch. After several replacements, was told it was a fault in the ignition. Ignition was replaced. Fan now works. Now headlights go out intermittently. Tech's can't figure out why.

When you go to put gear selector into park the ignition key gets stuck temporarily on my Isuzu Ascender 2003. Sometimes I have to wait 1 min or sometimes 10 min. To get the key out.if you listen real close you can here a electronic click.this just started about 2 months ago. I am worried about leaving the vehicle with the key in the ignition. It could be stolen or even car jack.

My 2003 Isuzu Ascender will not start occasionally. The keys even locked in the ignition one of the times. I had it jumped and the vehicle was ok for a month or so. This has happened 3 times in the past 4 months. The battery checks out ok. The dealer in winchester, va doesn't know what's going on. There are no default codes showing up in the computer.

When driving, my speedometer will become stuck between 30 and 60 mph. When it does, the speedometer will use the point at which it is stuck as zero mph when I am stopped / parked. When I start the vehicle moving again, I have to calculate the speed I am actually going. Example: If speedometer is stuck on 30 mph and I want to drive at 45 mph, I have to add 30 + 45 so when my speedometer is reading 75 mph, I hope I am actually driving 45 mph.

While driving the vehicle stalled without warning. The vehicle was towed to the dealer. The dealer drove the vehicle off the premises and it stalled. The vehicle had to be towed back to the dealership. The dealer has not been able to determine the cause of the stalling.
