Speedometer, voltage gauge, and tachometer gauges are not working properly.

- Lufkin, TX, USA

Speedometer indicated much higher speed than indicated (anywhere from 50 to over 120 miles per hour when completely stopped, or over 120 mph when driving at about 70 mph actual. Was reset by repeated restarting the engine (which lowerred the minimum indicated speed by 7-10 mph per start). Drove 120 miles with gps confirming speedometer's indicated speed, but I'm not comfortable issue is resolved. 2004 Chevy Tahoe lt, approx 30,000 miles. Never involved in any accident, no body/mechanical/electrical repairs or modifications.

On October 27th, the speedometer on my 2004 Chevy Tahoe began to stop working. My vehicle has 49K miles on it. The speedometer gets stuck at various points and will peg out at over 120. On many occasions, it will not come off of zero. If you turn the car off and restart it, it will drop the needle about 5 mph, but will never zero itself back out. I called the dealership (bill heard Chevrolet, collierville, tn) the day that it occurred. I was advised that this was a common occurrence and was a problem with the instrument panel cluster. I was also advised that it would cost around $600-$700 to repair. After doing some research, I have discovered that this seems to be a defect in GM trucks and SUV's. it is extremely dangerous! I asked the dealership if there was a recall and was advised that there was not. This is not just happening to me. I truly believe that GM should issue a recall to have this instrument panel repaired. People expect reliability when they invest this type of money into a vehicle and they are not getting it from GM or it's parts.

2004 Tahoe speedometer is pegged full scale while parked in driveway with engine off. Noticed several others having same speedometer related problems on internet forums. This is a safety issue that should be addressed immediately through a recall by the manufacturer.

Started vehicle November 14,2006 speedometer is showing at between 70 mph and 120 mph when at full stop. Unable to figure out how fast I am going. Internet is showing that a lot of GMC SUV and truck owners from 2003-2006 are having this issue. Dealers and mechanics are charging between $600-$800 to repair.

The speedometer started going way below the actual speed I was going. I'd have to turn the engine off and restart it and keep doing this until it gets back to normal. This went on for several weeks where it was fine, then it would drop below 0 at a stop sign, then would show 10 mph when I was actually doing about 35. Now it's doing just the opposite. The other night I looked down at the speedometer and almost panicked because it said I was going 90 mph! I was actually doing around 50. This is a very serious safety issue and GMC should recall.

Speedometer reads 40 mph when actually travelling 70 mph.

My husband and I own a 2004 Chevrolet Tahoe with 30,000 miles currently on it. We were driving home from supper last night when our speedometer quit working. We were doing 65 mph down a local highway when my husband looked down at his speed and the speedometer read 35. We stopped at a red light and the speed dropped to 0. when we accelerated, the speed stayed at 0 when we were doing at least 35. We then pulled over, turned the car off, recranked the car and then began driving. Still nothing. I have to say that this is definitely impacting our safety. We have no idea how fast we're driving. I googled the problem and found around 100 other GMC/GM car owners with the same problem. They are stating it costs between $500 and $700 to repair the problem and many times the problem still exists after the repairs. We have not contacted our local dealer because it is the weekend. We plan to call on Monday morning to find out the cost to fix the problem.

Electrical panel does not work properly. Have not had a correct reading in months.

- Round Rock, TX, USA

Speedometer no longer works. Reads to high, often staying at max speed or above while driving 55 to 65 mph. Reads ~50 mph while sitting still. Vehicle has miles.

Speedometer ticking and showing incorrect speed. Sometimes sticking on higher number and then on lower numbers and often not working at all.

At 37,000 miles, the speedometer on my 2004 Chevy Tahoe has stopped working. Reading erratically or not at all.

- Fayetteville, NC, USA

2004 Chevrolet Tahoe has a speedometer that does not work properly. Very erratic readings throughout speed range.

- Utica, NY, USA

Our Tahoe has 46295 miles on it. Last week, the speedometer became erratic. It sometimes works, but often shows speeds of 50-80 mph while the truck is in idle, and much higher when the truck is moving. After talking with many dealers, repair shops and other GM drivers, this is apparently a common problem that has not been addressed by GM. Apparently, the issue is with the instrument console, and other gauges may or may not be working as well. This is both a safety concern and a vehicle concern, as I may not know my correct speed, level of gas, etc.

- Dallas, TX, USA

2004 Chevy Tahoe speedometer quit working. Stays on 55 mph even when engine is off. Told it would be about $800 to fix. Now oil gauge is not working properly. It does not drop to zero. Oil in engine is at proper level.

I have a 2004 Chevrolet Tahoe Z71. At 40,500 miles the speedometer has started acting erratically, registering speeds up to 70 mph when the vehicle is at a standstill and registering a variety of speeds (none of which are correct) when the vehicle is in motion. My dealership insists that they have never heard of this problem before, however, I have seen on various web sites where there are literally thousands of owners of Tahoe and Yukon that are experiencing this problem...it is unsafe.

- Portsmouth, VA, USA

Speedometer is acting erratic, sometimes showing 35 mph when actual speed is somewhere around 70 mph. Other times it shows 0 mph. I'm concerned about this and wonder if there are other problems.

- Corona, CA, USA

Speedometer suddenly began to register incorrect mph. 0 mph sometimes is 30 mph or 40 mph or up to 70 mph. This happens suddenly you will look down and it will show you are going 110 mph when you are really going 60-70 mph. Took it into the deal and was told they have had more than several of this same problem. Cost to repair was going to be approximately $500, was told no recall has taken place, but they believe this was a defect and we should keep the receipt. We decided at this point to hold out and see if there is a recall as the speedometer works correctly approximately 50% of the time at this point.

The speedometer on my 2004 Chevrolet Tahoe broke suddenly while driving. It went to a "0 speed" of 40 mph. In other words, while moving at 25 mph my speedometer read 65 mph. I had to immediately slow down and was forced to move off the roadway because I was a hazard to other traffic. This was the second such incident. In January 2005 the exact same thing happened as I was traveling at the posted speed limit of 70 mph. I slowed for traffic and as I accelerated back to the posted speed limit my speedometer read over 100 mph. I did not know my speed and was forced to pull to the side of a major freeway. That speedometer was replaced under warranty. However, the replacement only lasted 32194 miles and 15 months. Besides the obvious danger in having a speedometer fail suddenly, there is the inherent concern that even if I was involved in even a minor fender-bender, the police investigating the accident would inaccurately find I was driving 40 mph above my actual speed and the burden would be on me to prove otherwise. An almost impossible task.

My odometer stopped functioning on my 2004 Tahoe Z71. I brought it into the dealer under warranty. The dealer advised me that this was happening to all of the Tahoe's and they were back logged trying to get the parts. It took over a week to get my Tahoe back. The dealer said that they repaired my cluster. The hour meter has 279 hours less now than it did when I brought it in. The mileage had 4 more miles on it. I called and advised the dealer that the hour meter had 279 hours less and asked him if they repaired the cluster or replaced it" he said they repaired it. So I called my brother in-law who's been a mechanic for Chevy for over 29 years. He said that they had to replace the cluster and just reprogrammed the mileage and hours. Why would the dealer make a false statement to me and tell me that they repaired the cluster when they must have replaced it? also, why hasn't this been a recalled by Chevy" it's a safety hazard and is happening to all the Tahoe's. I have only driven it home, so I can not tell you if the problem has been permanently corrected.
