problem #59

May 152015


  • 220,000 miles


While driving on the interstate at 70 mph the car switched to reduced engine power and reduced speed immediately to 25 mph, leaving me in the position to navigate through rush hour traffic to get to the side of the road. After happening a couple of times over a 30 period, it is now a regular occurrence. Each attempt to take the car in to a mechanic to be repaired results in the same issue occurring afterwards. Mechanics seem not to be able to determine the cause resulting in a completely unsafe car. The throttle body has been replaced, wire harness, pedal sensor, and throttle body sensor. Nothing has solved the problem!

Yesterday was driving home from work and came to a round about, slowed down and vehicle died (alternator gauge went below 14, oil pressure dropped below 40, and battery light came on). I lost all steering and brake pedal was stiff. Now vehicle continuously idles rough and will stall out if not on the throttle, idles 500 and lower. I have replaced mass air flow sensor, air filter, plugs, wires, O2 sensors, fuel filter, evap canister, alternator, and had throttle body cleaned. See there are many complaints filed of the same issues and wondering if anyone at GM has found a solution. Also have noticed GM has recalled the intake gasket but I have not received anything on this recall.

The contact owns a 2003 Chevrolet Tahoe. The contact stated that the instrument panel and the gauges failed intermittently. The vehicle was taken to an independent mechanic who diagnosed that the fuel gage and ignition switch needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 90,000. Updated 08/12/14 GM informed the consumer, since he was not the original owner, they would not fix the problem. Updated 08/14/14

Not sure what is happening to my car but it is very scary when it happens. Shortly after I start my car and it is warmed up, when I am driving it and I put the brakes on to slow down on a corner or at a intersection, my car will shut off. I can't steer and the brakes are hard to push. Please help, don't want to kill myself or my family.

The contact owns a 2003 Chevrolet Tahoe. The contact stated that smoke came from under the hood. The contact took the vehicle to the dealer where it was determined that the blower relay resister module failed. This failure caused the air conditioner to fail and it smelled like plastic was burning. The vehicle had not been repaired. The failure and current mileages were 135,000.

We noticed the speedometer and the battery was losing charge for several months. We have replaced the battery multiple times and had alternator and starter checked but could not find anything wrong with them. Did not take the vehicle to a Chevrolet dealer cause couldn't afford it the computer analyzing cost. Looked up on computer and in 2009 there was a recall on the "cluster" of the 2003 Tahoe and we were never notified. Chevrolet now says the recall has expired. We did not change addresses at all during this time period. (I also have a friend with a 2003 Tahoe and she did not receive a notice of recall either and has the same problems). What do I do about getting this problem fixed without it costing me a great deal of money. If they know something is wrong with one of their vehicles they should correct the problem especially if someone has a vehicle with a problem and never received a recall notice.

When driving, I noticed my speedometer registered around 80 and it was on a road that I normally go about 55. Many others were passing me, and I couldn't believe people would be going 90 or 100. And I certainly didn't feel I was going 80. I slowed down to 55, and I was crawling. I came to a stop light, and my speedometer went down to 15 at a stand still. I sped up again, and the same thing. Now it is stuck at 40 when sitting still and goes to about 100 when I drive. Apparently googling this, it appears to be a massive problem and no one can understand why a recall hasn't been issued. The dealer told me a bad cluster at $650 to repair. This needs to be escalated and Chevrolet needs to cover this problem. It is an extreme hazard on the road, and probably has caused many accidents and fatalities because of faulty readings. Please let me know what else I can do to get resolution.

The contact owns a 2003 Chevrolet Tahoe. The contact stated that the instrument panel gauges all failed and she was unable to read the fuel gauge, speedometer, thermometer, etc. The vehicle was taken to the dealer for diagnosis where they advised that the instrument cluster failed and needed to be replaced. The vehicle was not repaired. The manufacturer was later contacted and advised that there were no recalls for the failure. The failure mileage was unknown. The current mileage was approximately 168,286.

I was driving my 03 Tahoe, when an explosion went off in my vehicle. My entire back end of my Tahoe was literally blow to bits. There were no other vehicles or people around me. I immediately called the police dept. They were shocked to see the condition of my vehicle and said it looked to them, that it was a Chevy malfunction of some sort. I called my insurance company right away. They came out and towed the vehicle. They were also shocked to see the damage, and had no idea what or why it had happened. After assessing all the damage they found it would cost $2000 to fix the damage. Ins. Said they were willing to cover the damage, we had to pay a $500 deductible. I have five kids who are normally in the truck with me, thank god that morning, they were not. Glass was blown all over the inside of my truck, the noise alone would have damaged their ears, mine were ringing all day. I also contacted Chevy's customer service line. I spoke with an agent there who as no help, asked to speak to her supervisor, and she was no help. I then asked for whoever was above her, and I was told there was no one else to help me. I asked for a name, a phone number, an email anything for someone with more authority and was told that there was no one. This is wrong! what if I had been driving down I95, or what if I had my children with me?? then id be suing Chevy for millions! im asking is that they cover the $500 deductible since this is obviously something that is a safety issue. This wasn't normal wear and tare, this wasn't something that was just out of warranty and isn't covered. This is crazy! this is obviously a Chevy defect and needs to be addressed. I am sending pictures so you can see how horrible this was. This wasn't just the back glass shattered, this was like a bomb literally blew off my back door, while I was driving. Chevy needs to take responsibility for this.

I can be going down the highway running 65-70 mph and the reduced engine power light will come on and reduces my speed to 10 mph! I pull over, disconnect the battery cable and replace it, then I could continue for another week or so. Finally, I left the diagonstic computer in my truck and was able to capture the code P1125. The mechanic said to replace the throttle body. That was done in October. It ran fine for a while, but it started doing it again. The throttle body was replaced again! now, two months later, it's doing it again! no one can seem to fix the problem. Meanwhile, I am a female who travels the highways everyday going back and forth to work and I have been in several dangerous situations due to this problem that will not stop! as of now, I can not drive my truck and having to rely on carpooling again until it's fixed for the third time in the past 6 months. It also appears that several people are having the same problem with no results. Someone is going to get killed if this is not addressed soon!

I have noticed several complaints about this issue and it appears GM does not care. My speedometer is never correct. It runs 20-30 mph over (and sometimes under) what we are actually doing. This first was noticed several weeks ago (prior to actually failing) when it appeared that the needle would jerk (or step action) up or down, I know Chevrolet sent out a notice on this a year or so ago, but my vehicle was beyond their (GM) mileage requirement. I feel that their "bean counters" knew this at the time and it was against the american consumer. Anyway, this should be a safety concern by not only GM, but dot as well simply on the fact that one does not know how fast they are going. If caught off guard - thinking they are going 70 mph but doing 90 mph, loose control or run into someone. On the opposite side, doing 70 mph, glance down and see that they are doing 90 mph, they may hit the brake too hard to slow down and loose control or get rear ended. I could go on more with this issue, but it will probably not help (except add to the piles of complaints you are already receiving), so I'll quit for now. Thank you and please "light a fire" under GM's corporate people before someone gets killed over this.

  • 92,000 miles
2003 Tahoe has a defective instrument panel cluster - GM refuses to repair under their "special coverage" because that coverage expired at 80,000 miles. My vehicle is setup with a tow package allowing you to tow up to 7,000 pounds. It is critically important that you know your speed when towing a trailer or you can easily loose control. My speedometer is currently stuck at 10 miles per hour. GM has diagnosed and stated the instrument cluster is defective. GM does not consider a speedometer to be a safety device, but because they promote this vehicle with a "tow package" speed becomes a much more critical factor in vehicle operation.

The speedometer failed - indicating incorrect speed. For example, driving through town at the normal flow of traffic (20-30 mph) the speedometer indicates 50+ mph.

problem #40

Nov 082010


  • 85,000 miles
Driving along the highway at the posted speed of 65 mph the speedometer suddenly dropped to 0 and the needle ceased to move. Upon stopping at the next rest stop and checking for circuit breakers I realized that the problem was probably within the instrument itself and continued. Returning to the freeway I noticed the speedometer was once again functioning but cars were passing me at an excessive speed. I estimated, by traveling with the flow of traffic, our speedometer was reading 15-20 mph fast. After stopping again and troubleshooting with no success we resumed our trip with the speedometer reading approximately 10-15 slower than actual speed. Upon notifying our dealer I was told the speedometers in this year vehicle were failing at a excessive rate and the manufacturer had decided to offer and extended warranty to 70000 miles for replacement. I was never notified of this problem and warned of the defective parts in my vehicle. This particular trip was to Mexico and the reliability of my speedometer would be a particular concern on the roads I travelled. This part should have been recalled due to the excessive rate of failure and the manufacturer should have notified the consumer immediately.
