Don't buy this SUV, Had already bought before finding out that there are many many owners having the same problem with vehicle shutting down, left GMC dealer today after service request for problem with no fix as their mechanic said he can't figure out what electrical parts are bad as code did not tell him, He said he could start replacing electrical parts but no guaranty that the problem would be fixed. Called GMC customer complaint line and told to call National Traffic Saftey to register complaint, Everybody that owns an Envoy with this shutting down problem has to file a complaint with them before a recall can take place. Please call to file.
Engine and tranny are very reliable but the exterior trim and interior bits require a lot of fixing, typical GM. Body is still holding up well, rear deck lip is getting rusty but still looks good for a 10 year-old car. We drive the hell out of it and it has not let us down yet. Lots of DIY fixing if you are a handy man or shade-tree mechanic. Part are abundant and cheap, something else broke? ebay here I come!
