“While driving my cars brakelight came on and the car started to accelerate faster and faster. Pullled over as soon as I could and stopped the car and turned the engine off. The check gauges warning light comes on even when the car is sitting idle or when I pull up and stop at a red light it comes on.”

“Abs and brake warning lights and warning chime comes on every time we drive the car. The chime will go off after about 15 sec. Of chiming. Lights and warning on the readout stay on. Our mechanic said its the ABS module and GM doesn't have any. They have been on backorder for at least 8 months. He said it's a problem with like GM vehicles also. This is a safety hazard. Don't know to take it seriously or not. Don't know if our brakes are going to work. We need this fixed and we can't even get a part. Help!!”

NHTSA complaint #10520243, filed 2013-06, 135,000 miles

“I own a 2004 Isuzu Ascender. There has been a host of problems that I have had to deal with in the minimal 10 months that I have owned the vehicle. Two of the problems have yet to receive any type of fix from the local Isuzu service center. The first problem was the belt screaming every day. I took the vehicle in three times for the belt and they finally fixed it. The second problem is all four door windows. Debris consistently makes its way into the door and any time I roll down or roll up my windows my windows get severly scratched. …”
