Reliability indicates how models have performed in the past, providing the basis for predicting how the vehicles will hold up in the year ahead. These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey, our reliability history charts give you a rundown on how used vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system.
The Reliability score is based on our latest subscriber survey of 2006 GMC Envoy owners. The owner comments describe problems respondents experienced with this vehicle.

"The differential cracked down the center. We're sure it had originally happened in an accident months prior. The issue that we had with it is the amount of work that goes into replacing it. The oil pan goes around part of it and the pan is larger and heavier than any other oil pan we had ever seen. This was hours of work. Worth it, but very frustrating."

"After lots of random issues with our ignition and starter we figured out the under the hood fuse box needed to be replaced. There were a few broken wires inside of it that we read was a common but often overlooked issue. The cost to buy a brand new one was significant at about $600. So we waited until we found one at a salvage yard, which was awhile because it's a very reliable and strong vehicle that you don't find scrapped. Even with this issue I would buy this vehicle over and over, it's great! I highly recommend!!"
