Tl* the contact owns a 2005 isuzu ascender. While driving various speeds, the vehicle made a loud abnormal noise underneath the hood of the vehicle. The wires on the driver side headlights melted.

2006 Isuzu Ascender 5Transmission & drivetrainEngine & cooling

While driving on a major highway our 2006 isuzu ascender made a lot noise and stopped running, luckily we were able to drift off the highway onto the side of the road with out getting myself and my children killed. This vehicle has given me nothing but problems since I bought it used. A month after I purchased it I was told it would need a brand new engine because of "supposed" value taps and now I believe the transmission blew! I am so upset I hear there is a recall on the transmission but all I can locate now is the driver side door switch recall. Can someone help me figure out what has gone wrong with my car! *Tr

I first discovered that the fuel gauge was defective approximately over a yr ago. There was a diagnostic performed with a recommendation for repairs. I also discovered that there was a similar problem with the 2006 model that may or may not have been recalled. This was too much of a coincidence as there was no recall issued in my 2005 model. Similar problem is occurring with the oil gauge which is now as erratic in functioning. My vehicle is well maintained and therefore, I consider this occurrences to be a...

manufacturer's error, which should obviously be labeled as a safety defect. I have been stranded on the road a few times as a result of the erratic functioning of my gas gauge. I suspect that it may lead to other issues or concerns. As a customer, I recommend that the isuzu ascender manufacturers do the right thing by advising consumers, and taking appropriate steps to correct these safety concerns. *Tr
