Five problems related to automatic transmission have been reported for the 2006 GMC Envoy.
2006 Envoy only has 50,000 miles and the flywheel is going bad which may lead to future problems with the transmission there is also a fuel gauge problem where I fill up the car completely and it still reads empty. To replace this would be $800 dollars!!! I have found other websites where other people who own this car are having the same problems. There needs to be a recall!!!!!!! this is ridiculous. Thank you for listening.
Lost 2nd and 4th gears yesterday. Only 56,000 miles on my 2006 Envoy and should not have to replace my transmission yet. Not happy!!!!.
2006 Envoy denali. Consumer writes states gas needle stopped functioning the consumer stated the gas needle began to fluctuate in the beginning and since that time, the needle has been stuck on empty, and the engine light illuminated as a result. In March of 2009, when the consumer stared the vehicle, it sounded as if there was something metal tumbling around under the hood. Upon inspection of the vehicle, it was determined the engine needed to be replaced. On June 10, 2010, the vehicle would not start and had to be towed to the dealer. An inspection revealed a starter was needed. Also, an alignment was done and the rear brake light was replaced. On June 12, 2010, the vehicle would not come out of park. After 25 minutes and over 50 attempts, it finally came out of park. The consumer drove to the dealer, but they were unable to find a problem. September 2010, the consumer noticed the rear of the truck was sitting very low. The rear end air suspension needed to be replaced. The air condition randomly worked. There were times where the air would just start blowing and no buttons were pushed. Also, the defroster stopped working. The consumer continued to experience problems with the vehicle not coming out of park.
2006 GMC Envoy denali purchased 12/05. Beginning at about 10,000 miles the transmission would shift abruptly into 1st gear after the car had stopped moving. This does not happen every time but when it does it feels as if the car has been hit from behind. Dealer has not been able to duplicate the problem but states that other owners have reported the same problem.
I have had my GMC Envoy into the dealership on multiple occasions for a noise coming from the rear. I've been told that it is just a flaw in the design but it is a very annoying flaw. The noise is a constant squeal that only goes away if I take the vehicle out of overdrive. The dealership said from me not to drive the vehicle in overdrive because there wasn't anything they could do to fix it. As time goes on, the noise seems to be getting louder.
