I was driving down the highway after dark and my low beams completely went out. I could only get my high beams to work. Currently only one low beam is working and the other will not work even after changing the bulb or the fuse. I believe this is a huge safety concern especially having a young child. It was very scary going down the road at night and have your lights completely just go out. I have noticed that there are issues with 06-07 Envoy but I wanted GM to be made aware that 2005 models have been affected as well.

While driving my 2005 GMC Envoy my speedometer will stop working and register as 0 mph even when I am moving. It also has shown me travelling at a much higher speed at times. There are many issues with this that I've found while searching the web. It is unnerving and dangerous to not know the speed you are traveling. I have started to use a gps system when I drive to show my speed.

As I was driving the vehicle, the dashboard lit up and the odometer and all the information systems went to zero. This has happened often over the years. I took it to two GMC car dealerships and the first one said it was the kill switch installed by a buy here pay here dealership. The kill switch was removed and the dashboard continued to flicker. Then the car would not start, I took it to another dealership and was told they couldn't find anything. The car began to tribble, again I took it in and was told that I needed to clean the fuel injection system. I did that and bought a battery but that didn't help. The tow driver said it seems to be something electrical but the car dealership can't find a solution. Have you had this complaint before? not to confuse the complaint, I have several issues. 1. dashboard lights up and the information panels shut down (all are at zero) 2. the odometer goes to zero and the instrument cluster is black 3. tribble underneath while driving feels as if the car is shaking thank you for any assistance you can provide.

This is a recurring problem with not just my vehicle, but after a very simple web search a vast number of these GMC Envoy vehicles. When traveling normally the speedometer decides to either drop its speed by 20-30 mph or raise it even as high as 120mph. When traveling in the city or hwy where the speed limit zones vary rather frequently and in heavy traffic, the driver naturally reacts to the needle unaware that the speedometer is actually faulty. I have therefore braked hard to reduce my speed when in fact I was going the speed limit. That can result in an instant to a rear end crash based on normal reactions. GM obviously are aware of this issue as there are multiple on line complaints for this same issue and indeed they issued a recall for similar GM trucks. They however continue to ignore the Envoy problem and leave the owners "live or die" with the problem. How this cannot be considered a high priority safety issue is a mystery to me. Even 10 mph variations in heavy traffic mean potential accidents from bumper hugging drivers behind. This issue is more common in the extreme cold weather and thus I am of the opinion that there is a definite testing validation problem.

I was driving about 25 miles per hour @ night when all the warning lights on the dash came on and all the gauges read zero except the speedometer and tach, transmission gear selector wasn't indicating what gear I was in & radio also killed. Headlights, wipers & directions were still functional. I only had a mile to drive to get home. Parked vehicle in garage and shut off....only to discover that power locks had failed and I was locked in car, power windows were also out! removed key from ignition and fortunately the remote key fob unlocked the door. Had this been an emergency situation, I would have no way to exit the car nor would any passengers. Anyone else having this problem? I contacted dealer to apprize them of this new problem and was advised that if it's intermittent they would have problems fixing it. The vehicle seemed to reset in the morning and all dash warning lights back to normal!

The oil pressure gauge is reading above 80. Had oil changed immediately. Was told that there have been complaints regarding the mis reading of the instrument panel. Contacted GM and was told that at this time they are not covering the repairs and that it is the consumers responsibility to replace the engine sensor system. GM has some of the rudest and nastiest customer service representatives. I had to call 3 times in one day. They even hung up on me. I spoke with [xxx], [xxx] and [xxx]. I asked about the safety of the vehicle and other potential problems, such as engine fire or entire system shutting down and not responding. They had absolutely no answer for me other than they are not covering the cost of the repair. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The SUV has shut off on me three times in the last 2 1/2 yrs (the time I have owned it. ) each time I was just driving on the city streets going about 30 mph. All of a sudden the car just shut off and all lights, etc just turned off. I am concerned wondering if perhaps there is a problem with the 2005 Envoy ignition switch as well" no, it was not the battery or anything to do with the servicing of the SUV. I take care of the vehicle and I don't drive 200 miles a month. I guess I am lucky that each time I was not gong fast and the SUV just slowed down and came to a stop, on the side of the road. However the 2nd time, I had 2 little girls in the car with me and it concerned me a great deal.each time the SUV started back up and I was able to resume driving after about 2 minutes. What if I had been going faster " what if I had been on a highway etc. If there is an issue with the ignition, please lets fix it before someone dies. I will make sure everyone in my family know about the shut off problems I have had with the car. Just in case something happens while I am driving it.
