2006 gmc envoy_denali
I havent had many problems with the denali, except for the bad rod bearings and crankshaft. ouch!! I could hear a engine tap right b4 shifts, or if i would rev engine in park. I immediatlly got sick in the stomach. jk.It only has 66k, thought these engines were bulletproof??B4 I panacked I figured it wouldnt hurt to call the dealer, have them run the vin. I only had it for about six months so who knows how its been maintained. Im sooo lucky to find out that I have a GMC certified warrenty. I didnt buy it certified , someone else did in its past and the warrenty stays with the vehicle. So the only thing im out is a car for a week now, and the $35 of mobil1 I just put in her. So moral of the story. Check and c if you have a warrenty!!! Dealer says crank is $1000 part.
