GMC Owners' Reviews
I used to work at Chevrolet Dealership before I bought a truck i did My home work. I bought a 2006 Sierra because in 2007 the Cast Iron blocks went away and more aluminum started being introduced as well as plastic. However, I did have a major problem with the Clutch some truck that were assembled in Mexico utilzed a master cylinder with a shaft approximately 3/16" too short making it very difficult to Clutch. That one was hard to resolve especiallly because GM and the Dealers wouldn't help. Less is more when it comes to vehicles in my book Less electronics less fancy stuff more time for me and my wallet.
I have had problems with my envoy that the service center had no idea what was the problem. Paid money too have the electrical system checked and two days later my alternator checked out.....and they said it was good......be careful if your engine light comes on its a warning the alternator is checking out....beware spending money to have them nothing is wrong.....good luck....envoy owner....
This is the worst piece of JUNK we have ever bought. We have spent a ton on money on this piece of junk and it still doesn't run right. Wish we had never bought it.
on a cold start the oil gauge will go to 80 then drop to zero will stay on zero until 10 minutes or more of driving, then when I come to a stop it will jump to 80 and stay on 80. Please advise of possible problem and estimate repair cost. Thank you.
I am very excited about this truck having drining it for 7 years now and beyong regular mantianance and hour pads - I did nothing to the rotors, until the 4th set of pads. I actually bought some high end rotors and pads and changed them myself. very easy and saved about $1,000. The only other change was the alternator and the air condition belt. Well, the heated steering, cruise control, no longer work and side mirror will not close. I bought this truck new with 45 miles on it and with 0ver 150,000 she still runs like new.
