Tl* the contact owns a 2005 isuzu ascender. The contact stated that the fuel gauge, speedometer and oil gauge were all providing erratic readings. After refueling the fuel tank, the fuel gauge would provide an erroneous reading of zero. The oil gauge pressure would move back and forth when the accelerator pedal was depressed. The vehicle was taken to a local mechanic for diagnosis and they stated that the fuel pump, sensor and the lever needed to be replaced. The manufacturer was notified and advised the contact to call general motors because the parts were manufactured by general motors. The contact notified general motors but was referred back to the manufacturer of the vehicle. The vehicle was not repaired. The failure mileage was 90,000.

The isuzu ascender 2005 has had a problem with the fuel gauge, speedometer and oil gauge. All are reading erratically. Fill the tank the gauge reads that is needs gas. The oil gauge is completely as have changed out the fuel gauge inside the fuel tank for about $750 that worked for about a year and now the problem is back again. Also the check engine light is always on. The mechanic says this is an error and just resets it after checking the on board system.

My speedometer is rarely accurate anymore. It can be fine when I start out but then jump to an obnoxious speed and the next thing I know, it says I am going 120 miles an hour and 65 miles an hour when stopped. The gas gauge is not reading correctly and the oil gauge is stuck all the way over.

I've been having the same issues with speedometer and gas gauge. I bought the vehicle used and the engine light came on a day after I bought it. The speedometer stopped working as I was driving it off the lot. When back to the dealer and they fixed and it worked for a few months. I have noticed that the speedometer goes haywire when it drops below a certain temperature and the gas gauge when it rains or it's humid. I know it seems ridiculous but I had no problems during the summer months with either up until now rainy season. It has only come off once, when I replaced the battery but it came back on a day later. Hope someone figures something out!

I have been having issues with my gas gauge for about 3 weeks...at first I would fill up the tank or at least think it was full as the gauge would move all the way over to full then after I would stop pumping and turn on the car the gauge would go down to 3/4 tank and fluctuate back and forth between 3/4 and full over several days. Then yesterday I went and filled up and decided to not use the gauge as a measuring system and instead just let the pump go until it clicked off as it does when tank is full so I did this and the gauge went up to full then bounced back to empty and now my fuel low light is on and I cannot get any range reading on mileage for gas or anything. Also it should be noted that about that same 3 weeks ago my speedometer stopped working briefly starting off at 65 MPH at rest then it gradually made its way back down to zero at rest and has since seemed to be ok.

The first time I realized my gas gauge wasn't working, I was sitting at a traffic light. The gas hand read half full. I made the turn at the intersection and the car stopped running. At this point, I had no control over the steering wheel or anything. Traffic was heavy so I wrestled with the steering wheel to coast to the side of the road. Since then, other gauges in the instrument panel have stopped working. Also, my headlights work on bright only. I had the low beams changed and they still don't work. There seems to be a serious electrical issue with this vehicle. With the number of reports, there should be a recall to address these issues.

Instrument panel cluster performed erratically the speedometer goes crazy and restarting the car certain amount of times then reset it to 0 MPH. Some gauges are not working (oil, RPM).

2005 isuzu ascender ~ oil gauge stopped working about 2months ago (august 2011) and the speedometer went out shortly after that. Took it to the dealership and was told "it was probably the fuses". Changed the fuses out, but that didn't help! In fact there is even another problem now! The system panel lit up... (sept.2011)...w/ lights and bells that read (check brake system) which is a safety issue, so I immediately took it in to be checked and was told "the brakes are all in great condition and was not the problem!" well there is a big problem if all the owners of this type of vehicle are all having the same issues and not getting any help from the manufacturer!!!!

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.

This is regarding my 2005 isuzu ascender. While driving on highway i78 in nj sudden noticed that speedometer gauge jumped to 120 MPH but the speed on my portable navigation was showing only 68 MPH. After that speedometer gauge shows 70, 80, 90 MPH or so when vehicle is only at 20, 30 or 40 MPH. Now is passed 120 MPH and not coming back to normal. This seems to be a faulty speedometer. I have never seen any speedometer this way. This is the first time ever facing this issue. Now I have no idea at what speed I am going on.

While driving on the highway, instrument cluster gauges became erratic and stopped reading completely. Works again sporadically, but impossible to predict next failure incident. Failure incidents increasing in frequency, but still unpredictable.

Speedometer failed. Driving around 30 MPH when the gauge jumped to the end of the meter and dived back down quickly. Gauge will intermittently work but only for short time frames but then will be off by 20 to 70 MPH and jump at erratic moments. Issue happened around 95k.

The vehicle speedometer works intermittently. It will work fine for 5-10 minutes of driving and then does not register the correct speed and eventually stops working all together. I understand this is a well documented problem and that gm is aware of the problems. I contacted isuzu customer service and was told that a broken speedometer is not "a safety issue." when I questioned that statement the representative did admit that it is a safety issue, but gm is not doing anything about the known problem. A 5 year old car with less than 50,000 miles should not have this kind of problem.

It took a while before the electrical issues to progress where they where verifiable with solid symptoms as in transmission faults and poor performance along with loss of communication to steering wheel controls, AC and blower failure, radio etc. The full extent of what is affected and how it will progress as it had to this point is unknown to me or service people. The wiring has been modified and the ignition has been replaced 3 times to try and resolve this issue, and the effects of modification did not work and what that will bring about is unknown at this time. I have notified manufacture, but after I learned of this site and looked at chevy trail blazer and isuzu ascender electrical issues ( same car ), it is clear to me that I am not alone and there is not a known fix for this hardware or possibly software issue. The vehicle has stranded my daughters, and guest 3 states away form home after wiring modification that was supposed to fix the electrical issue. Thankfully we got stranded in a town and not in the middle of desert on the way to colorado.

While driving at slow speeds vehicle will cut off. You lose steering and brakes do not work well. First failure was 3 weeks after purchase. Vehicle was purchased new. Three dealerships have attempted to fix to no avail. Manufacturer was notified twice with no resolution.
