What owners report

Driving on interstate 91 south, glanced down to see my speedometer indicated I was traveling 75 miles perhour let off the accelerator to decrease speed when I realized the vehicle behind mine had to pull around my vehicle to avoid hitting mine in the rear. Several miles later I discovered my speedometer indicated I was traveling 120mph although keeping up with traffic. As I pulled of highway and hit my brakes the speedometer decreased in speed, although when at a complete stop speedometer indicated I was traveling 30 MPH. This causes some concern since I only have 41,119 miles on my 2005 Envoy Xuv. I contacted GMC and was told there was no recall on my vehicle and scheduled a service appointment with a GMC dealer to figure out the problem. This issue after some research had been an ongoing problem and find it difficult a recall has not been made for this issue. …

The speedometer has gotten stuck at 120 MPH & will not reset... This has happened off & on & I was usually able to reset the speedometer by turning on and off the vehicle several times... But now, it has officially stayed at 120mph. I am unable to tell how fast I am actually driving. I know GMC had similar issues with their Chevrolet vehicles - & that resulted in a class action lawsuit to have them issue a recall.... I would really like to see a recall on this... It is unsafe to drive this way!!

First noticed reduced radio volume as if speakers were not completely connected. They radio would work correctly from time to time. Service dept said it would have to replace entire dash system. Then noticed rear door/tailgate would not open as a door, next the tailgate stopped functioning all together; this makes the rear part of the Xuv useless and dangerous. Dealer stated that is electronic and that all tailgate/rear door hinges rusted due to water coming in where rear window is/ estimate is over $650.00 and it would happen again!!! Next the driver's door will not unlock except by manual unlocking from inside and sometime the key will not unlock to driver's door. Key fob will not work on driver's door, tailgate/rear door; however, key fob works on passenger doors. Dealer stated that the tailgate/rear door issue has a history of this happening so why isn't there a recall???? …

On June 8 2013 both the driver and passenger seat power adjustments ceased to operate or respond in any way. Both seat stuck in a full back position. The next day, June 9 2013, the vehicle was at idle and in park for no more than 4 or 5 minutes, when an odd smell was noticed. A small electrical fire to include sparks and a lot of smoke then erupted under the passenger seat. The driver turned the vehicle off, and the passenger and 18 month old child, and driver all exited the vehicle. The fire died, and the smoke cleared. Waited 15 minutes, restarted the vehicle with no problems. The vehicle was dropped off the next day, June 10 2013, a Chevy dealership. The vehicle is currently under diagnoses.
