This suv made a loud sound, began to drift, in the rear, at hwy speeds before it tipped over and began to roll, ejecting my two minor sons from the passenger cab before it eventually landed on its side. the roof was molded in a triangular shape, preventing it from resting on the roof as it tilted back onto inside and remains after the last roll The triangular shape was created in the metal after the stabilizing structures gave way almost immediately providing possibly no protection to the patrons inside the carrier cab of suv. demonstrating its inability protect its occupants.

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.

Accelerating while entering a freeway, took foot off the gas and the vehicle continued to accelerate. Applied brake but vehicle continued to accelerate. Put vehicle in neutral to try and slow down and again applied brake. Vehicle began to spin to the right and we hit the guard rail, hitting the passenger rear bumper and the driver's side front bumper. Side air bags deployed. Car spun into the middle travel lane and began to spin around. Car was slowing down and was able to turn car off. Fortunately no other cars were involved. An off duty sheriff's deputy stopped and said he noticed smoke and thought the car was on fire but no fire occurred. When state police arrived they asked us to move the car to the break down lane. Was able to put car in reverse and backed car to breakdown lane. Tried to put car in drive but car wouldn't go forward.

The speedometer on my 2005 gmc envoy has stopped working properly & also the thermostat gauge & the gas gauge. This is a common problem among envoy owner's & is a safety issue. The instrument cluster needs to be recalled & replaced.

Fuel gauges is showing empty when the vehicle is full of gasoline. Odometer is not reading the correct speed. Temperature gauge is malfunctioning. On google several complaints about this is widely known. What is gmc doing to resolve these issues? The tax payers help bail out gmc and now we are not being treated unfairly where is our justice?

Fuel gauge does not go above 1/8 tank. Speedometer "sticks" usually at highway speed and when stopped does not return to zero then when vehicle is moving again the new speed is accumulating on "stuck" speed. Sometimes speedometer "sticks" before reaching steady speed and when vehicle is stopped the reading is below zero in this scenario when the vehicle is moving again the "registered" speed is below actual speed. As I drive 1,000 miles a week, it is quite important to know how much fuel I have in my tank and of course how fast I am traveling.

I bought a 2005 gmc envoy used but in good shape. After about 5000. Miles the speedometer started to read 120 MPH. It reset itself a couple of times but now it's completely stuck at the 120. Also the gas gauge sometimes works and sometimes it doesn't. I can fill it up and it will ding and the light comes on and it won't show a drop of gas on the gauge. Then a day or so later it will be fine. Also the check engine light is on. I replaced the gas cap since the owners manual said it could be a faulty gas cap. It helped for a few days but it's back on. After reading all these reviews and complaints I'm sorry I bought it. I don't have the money to keep getting it fixed. It cost a $100.00 for the dealer just to hook it up so they could tell me it needed a speedometer head.(?) that will only cost $468.00. But that won't fix the check engine light or the gas gauge. I'm worried that I'll get a ticket because the speedometer doesn't work or run out of gas when the gas gauge isn't working.
