2005 GMC Envoy SUV Denali Rwd 4dr SUV (5.3L 8cyl 4A)
I own a 2005 XUV v8 with 111,450 miles on it. I have had to replace 11 window regulators, drivers side front, mid gate, and tail gate. Funny thing is GMC says they do not have a problem with these, what with the $450 plus replacement I guess they don't have a problem. I also had to have the air bags replaced at 80,000 miles. I will never buy another GMC or recommend one.
I bought this SUV, certified pre-owned, in 2008, preparing for a move to rural New Mexico. This Envoy's reliability has been flawless. It's gotten us through miles of extremely muddy roads with no problem. Last summer I had an Alpine car stereo installed for the USB and Bluetooth capability.
My criticisms are rattling door panels and a poorly placed cupholder on the console.
We had a painter do our interior last summer. He drives an older Envoy. 243,000 miles on the odometer, which tells me I can drive this one for quite a while.
I had Leased a 2004 Envoy, mostly highway mileage. Towards the end of the lease had engine code for misfire cylinder4. Vehicle was turned in as the lease expired and I thought nothing of it.
Purchased a Pre Owned Certified 2005 GMC Envoy SLT, in 2008. In 2010 had to replace Cam Shaft sensor, (this was early warning of problem to come). A few months ago had misfire cylinder 2, replaced the coil & plug, code cleared engine light off. Problem resolved or so I thought. Last month misfire cylinder 4, replaced coil & plug, still misfire. Had diagnosis done via computer. Low pressure in the cylinder. From the blogs on all the sites cylinder 4 & 5 seem to be issue. GM knows but dosent care
I love the truck, it has been a great family vehicle. But I am hesitant to spend $2,000.00 to $3,500.00 to machine the head and replace a cam shaft.
This is an all too common problem with all Envoys for it to be a random issue.
GM should buck up and set up a RECALL for their mistake.
Model is discontinued need we say more. GM has to know the issue, every blog has same problem 4 & 5 misfire and pressure
