Speedometer showing different speed than actual. Car will show it is going 50 mph and will be actually going 60mph. Car will show going 45mph and will be going around 56mph. Took to mechanic and he said was probably stepper motor. Estimated cost to fix is $365. 2nd problem I've had with dash!!

The contact owns a 2004 Isuzu Ascender. The contact stated that the speedometer moved back and forth and does not show the correct speed. The speedometer will read over 100 mph and then become stuck. The vehicle had to be turned on and off in order to get the speedometer to read correctly. The dealer stated that there was a problem with the computer, but the contact was convinced that it was an electrical problem. The contact stated that when the fan was set below level five, the instrument panel began to function. When the failure occurred all of the warning lights began to flash on the instrument panel until the fan was placed on level 5. the VIN was unknown. The failure mileage was 50,000 and the current mileage was 92,000. Updated 03/14/11

I own a 2004 Isuzu Ascender and several months ago the instrument panel began working erratically, and now, not at all. Specifically the tachometer and speedometer are non-functioning, and the voltmeter and oil pressure gauge give false readings. I have contacted the dealer and am told there is no recall and the warranty is now up. I have contacted Isuzu of America and told there is no recall and will have to take the vehicle to the dealership. Because this involves the speedometer, I feel this is a safety issue. Additionally a co-worker owns a 2004 GMC Envoy which is a sister vehicle, and she is also having the same problems.

Tachometer needle went straight down and gave incorrect readings, then a few weeks later the speedometer did the same thing then a week later the oil pressure gauge began to give incorrect readings. My mechanic says he has already had one 2004 GM vehicle in for the same thing.

Just to let you know. GMC Envoy, Chevrolet trailblazer, Buick rainier, Oldsmobile Bravada, Saab 9-7X, Isuzu Ascender they are all exactly the same vehicle that has just been rebadged. I personally drive a 2004 Isuzu Ascender, and I can't get GM, Chevy, or Isuzu to fix it without charging me $475. My tachometer always reads wrong. My speedometer sometimes reads wrong and my gas gauge does not give me the correct reading. This can be real dangerous. The speedometer issue is more wide spread than you guys think.

The speedometer in my 2004 Isuzu Ascender which is a GM product is giving false readings and shows higher and/or slower speeds than the correct speed. I am aware that this is a nationwide complaint among other GM product owners. The dealerships are refusing to fix it, citing "out of warranty" excuses and saying that it is not a safety issue. It is in fact, a safety issue and should be fixed at no cost to the consumer.

: the contact stated while driving 55 mph, the dashboard gauge lights began dimming. There were no warning signals prior to the incident. The vehicle was taken to the service dealer who determined that there was a short in the battery. A new battery was installed but the problem persisted. The manufacturer was notified and could not determine the problem or offer a resolution.
