I purchased a used 2004 GMC Envoy slt, with an extended warranty from Grand Prix auto group, hicksville, NY in August 2008. Soon after purchasing the car it stalled while we were at a red light. Immediately brought the truck back to the dealer and they said they fixed it, may I mention it never stopped stalling. Then the speedometer broke again. It constantly says I'm traveling 120 miles an hour. Once again, brought it back to the dealer, they tell me I need to go to a GMC dealer, I do, they replace the information cluster and speedometer, had to pay a $ $300 deductible. This was in March 2009. Driving the other day October 2009 and the speedometer once again says 120. Get pulled over, get a ticket for a broken speedometer. The officer was aware I was not traveling at that speed, and even when I tried to explain, wanted to hear none of it. So now here I am again, broken speedometer, engine that stalls often and a summons to boot. I need help and I don't know where else to turn the dealerships are of no help. Jacqueline king

On a 2004 GMC Envoy, the whole odometer/speedometer went out. Nothing worked and I had to get my whole instrument cluster replaced.

2004 GMC Envoy instrument panel cluster suddenly started not working. It hasn't worked properly since it happened and reads incorrect speed, oil pressure, and fuel levels. Nothing has been done to correct the failure by the dealer.

The speedometer on my 2004 Envoy has been inaccurate at least 5 times in the last 9 months. I noticed that this problem arises when there is a spike or dip in temperature outdoors. For over 24 hours the speedometer was stuck at 120 mph. The speedometer corrects itself over the course of 4 or 5 days depending on how many starts and stops I make around town. I see that GM isn't going to claim any responsibility on this matter so I just pay very close attention to my speedometer when driving and stay in the slow lane. Can't afford to pay the big bucks for their mistake.

I have 2004 Envoy have had problems with alternator. Started about 6 months after I bought the Envoy had I replaced 3 times then started having problems with back seat window on passenger side not rolling up. Then my girlfriend had a flat on side of road and could not get spare down I had to go out and cut the cable that holds it up. That is a unsafe thing to do on side of hwy should not take 45 min to get spare down. Headlights dim and brighten gets dim enough that makes hard to see.

When traveling down the road and putting on the brakes the headlights and dash lights flicker. The flickering is so much that is looks like we are flashing other cars.

My 2004 GMC Envoy has developed an erratic speedometer. The speedometer reflects inaccurate speeds causing an unsafe driving condition. I contacted my local GMC dealer who researched to find no recall concerning this problem I then submitted my complaint to the BBB hotline and was rebuffed their also. I have consequently done additional research and have found that GM has issued a special coverage adjustment bulletin for 2003-2004 Cadillac escalade, Chevrolet Avalanche, Silverado, Suburban and Tahoe, GMC Sierra and Yukon. The speedometer unit in these models are very similar in both appearance and are manufactured by the same supplier GM uses. The adjust bulletin is #07187 dated September 28,2007 and covers the condition for a period of 7 years or 70,000 miles regardless of ownership. After visiting many GMC and Chevrolet chat rooms it is readily apparent that this problem is very common and will eventually result in a fatal accident. I am requesting that the NHTSA formally investigate this problem before this happens.

Problem started out as erratic reading with speedometer. After approx. 5 days speedo finally wouldn't register at all took vehicle to authorized dealer to be repaired - $555 charge to replace instrument panel and reprogram. Called GM for financial help as I noticed there were alot of failures with GMC SUV's and pick-up trucks. GM would not acknowledge there was a problem which I feel is totally disingenuous. Speedometer is necessary to be working as a safety issue. Because I was out of state at the time of part breakdown I felt I had no choice but to have problem fixed before my return trip home (1250 miles). Judging how many other Envoy have had same problem, I feel GM is dodging their responsibility I noticed that there has been class-actions against them for the same problem.

The speedometer gradually decreased from interstate speed (70mph) to 0 mph while driving. Speedometer fails to operate. I personally know 2 people who have had this happen on a 2004 Envoy.

The tach on my '04 Envoy with 67K miles started acting erratic and has completely failed just as all the other service bulletins. This has corrected itself buis till erratic. GM needs to address the faulty electronic gauges on these '04 Envoy.

- Gilford, NH, USA

Instrument cluster. Speed odometer and tach not accurate. I have had 2 speeding tickets because I don't know how fast I am going. Not sure of the date it first happened but it is getting worse. GM dealer in my area was rude to my wife and said they will not cover it.

I began experiencing problems with the instrument panel on my 2004 GMC Envoy a few months ago. The entire panel would go out and all the gauges bottomed out. I could not tell my speed, gas level, rpms, etc. The panel would stay out for a few days then return to normal. Also on occasion the speedometer would stick at 60 mph and only correct itself if I pulled over and turned the truck off then back on. Finally, about two weeks ago the entire instrument panel went out and has never come back on. I have dropped it off at the dealership for service and am awaiting their response. This problem has caused me to run out of gas twice because I was unable to judge my fuel level. Luckily both times I was in an area with easy access to the shoulder of the road. I currently have approximately 55,000 miles on my truck. (I can't be sure of this, however, since the odometer is a part of the panel that is out.) this is a serious and, according to my research, recurring problem the GMC should be forced to correct and pay for.

The contact owns a 2004 GMC Envoy. While drving 20 mph the speedometer stopped working. The dealer stated that they assumed it was a part of the manufacturers recall and repaired the vehicle. The dealer confirmed after the repairs were made that the vehcle was not within the recall VIN range. The dealer has billed the contact for the repairs. The failure mileage was 52,000 and the current mileage was 55,000.

I have a 2004 GMC Envoy in which the speedometer has stopped working. I researched this on the internet and it is a common occurrence. I almost caused a wreck because the speedometer said I was going faster than I really was and the cars behind me almost ran into me. This is a safety issue that I feel should be investigated. Could you please assist w any recall measures. It costs over $500 to replace this.

- Manhattan, KS, USA

My 2004 GMC Envoy mph and RPM gauges are not working properly, I called the dealership and an extended warranty was put on all GMC/Chevy trucks and SUV for the dashboard cluster except for the Envoy, any newer models. The part is at least 500 and advised can only be done by dealership due to programming. Im furious, my truck is only at about 53,000 miles. This defect needs to be under recall for the Envoy asap!

This past month the speedometer set at 40 mph with car in "park" position. Afterward when driving, my actual speed had 40mph added to the reading. This has occurred three times so far in October 2008.
