Selected complaints filed with NHTSA by 2005 GMC Envoy XL 370 owners, lightly cleaned up (personal details are redacted by NHTSA).

I had trouble with the gauge that shows overheating.I took the car in to put in a thermostat thinking it was the problem,but when I took it in they said that my cluster was bad and the gauges were messed up.I paid $392.00 for the cluster and $100.00 for labor.I bought this vehicle used with 119,000 miles on it on 6/20/2011 and on 2/23/2013 I had the cluster replaced with mileage of 132,356. I put on new brakes at this time since the had a habit of grabbing and making me slide and jerk to a stop.the only problem I have now is the the door locks mess up once in awhile but other than that I take my Envoy in every 4000 miles for an oil change and a check up it is now 12/15/2015 and I only have 142,000 miles on it and it is still running OK.I keep checking once a month for recalls on my vehicle sometimes a dome light will come on .but not often.my Envoy has not rust and the interior is in as …

Tl* the contact owns a 2005 GMC Envoy XL 370. While driving approximately 30 MPH, the check engine warning indicator illuminated and the engine stalled. The vehicle was towed to an independent mechanic where it was diagnosed that there was a loose bolt within the vehicle's sensory system. The vehicle was repaired, but the failure persisted. The manufacturer was not made aware of the failure. The failure mileage was approximately 142,000.

This piece of crap vehicle in which the entire instrument cluster has completely failed starting with the fuel gauge. This failure then LED to the failure of all the gauges minus as of right now the speedometer. The tac works when it wants to. GMC now has went back and wants to "fix" the sending unit only to the gas tank (gee....thanks for the rush GM considering this is a 2005 vehicle and the year is now 2013...and people have been complaining for darn close to 10 years about them now!! Nice job stepping up!!).....thus correcting the gas gauge ..we hope (which I have been told will probably last for approximately 1 year...if we are lucky....oh joy for us!!!) yea...thanks GM...I now know I will have 3/4 of a tank of gas when my freakin vehicle overheats on the side of the roadway since the rest of the gauges do not work because you people will not back your g.d. Products. …

The oil gauge went out first and the dealer stated the oil sending unit need to be replace and it would cost me over 300. 00 dollars, then next the engine coolant gauge starting going crazy. I took my car back for an oil change and was told the instrument panel cluster needs replacing. I went back to have my engine coolant gauge look at by the dealer because I did not want to be stranded somewhere with my 4 year toddler in the car and paid for the dealer to replace the engine coolant thermostat based on their instructions. Still my oil pressure gauge was pegged out and now the speedometer gauge has completely stop working, so I took my car back to the GMC dealer and was told the instrument panel cluster need to be replace and that would take care of the oil pressure gauge too. …

While traveling on the interstate in the evening, the speedometer became "stuck" at about 30 MPH. We pulled off at a rest stop and turned off the engine, hoping that the speedometer would reset itself. Upon restarting the vehicle, the speedometer sat at 60 MPH, even though we were still sitting at the rest stop--not moving. We tried turning off the engine again and this time when we restarted the vehicle, the speedometer needle "stuck" at over 120 MPH--again we were not moving. The speedometer needle stayed past the 120 MPH mark for the entire trip home. Fortunately, we were able to follow some friends home. A few days later, we took the car to a mechanic. He indicated that he had seen the speedometer problem before with other gmcs and he then replaced the "instrument cluster" in our vehicle. …

2005 GMC Envoy speedometer failure. While driving the Envoy over stevens pass ( washington state) the speedometer began reading a significantly lower speed than my wife was driving...at first she tried to speed up fearing that she had absentmindedly began to slow but soon realized that the speedometer continued to reflect even lower speeds. After going to the internet I've discovered that this has been an ongoing problem with GM trucks for the years 2003 thru 2007 and actually there has been a class action lawsuit filed. ( I don't know the disposition) the remedy is replacing the entire gauge cluster at a cost of around $500. Seems unfair considering this is a problem of gms' and apparently kept secret while charging their customers for their problems . [redacted]

Gas gauge reads empty at most times, never gives accurate measure of tank fill. Also check engine light turns on sporadically, although diagnosis by engine tech confirms no bad codes are causing this warning light to glow. Research on the internet and talking with dealerships and mechanics have confirmed that this is a very common defective part problem that GM has not issued a recall on. Hundreds, probably thousands of frustrated drivers. It effects GMC envoys, Chevy trailblazers, and other GM makes in 2004 - 2006. Thank goodness taxpayer dollars are keeping them afloat! God forbid they actually support their products and maintain customer loyalty and integrity!

2005 GMC Envoy smoke from under the dash then the blower quit blower motor resister burned up and melted wiring harness and plug at the resister did not blow fuse replaced resister and harness 3 months later burned up resister again and harness still did not blow fuse contacted dealer they told me to change the same parts that they've seen it before I researched the wiring and consulted a electrical engineer he said the problem was at the blower motor because the resister was between the switch and the motor if the motor was worn and pulling to many amps that it would burn the harness and resister so I replaced all three items and have not had a problem since.

The speedometer fails to represent true vehicle speed. Using a GPS we can monitor the inaccuracy in the gauge reading. The speedometer reflects a speed of 25 when actual speed is 45. This becomes worse as the vehicle is driven as the speedometer completely fails to register speed. An identical issue was present on a 2003 Chevrolet truck we own which was repaired by GM under an in-house program resulting from a lawsuit. GM has declined to repair this same problem on this model. If a driver cannot accurately determine his/her speed at any given moment the possibility for safety related instances are increased for the driver and others.

My speedometer gauge works when it wants. The car can be in park, however speedometer May read 30mph. Just recently I was traveling out of state and while on the interstate, my speedometer quit working and the needle went to zero. And in a like manner, on the way back, my speedometer read ten miles below my actual speed and almost caused me to get a ticket. From asking around many Chevy and GMC vehicles with a similar gauge face have experience a problem with one of their gauges. Please help me. The dealership says the part cost around $300 plus the price of labor. I have had one problem after another with my GMC Envoy XL 2005.
