Owners/service Manual Problems of GMC Envoy

My rear lift gate does not lock with or without the key fob nor with the power door lock button. There is no manual way to lock my doors it seems to be a poor design and a safety factor. My wife is afraid to drive because anyone can open the lift gate and rob her or even myself.

First noticed reduced radio volume as if speakers were not completely connected. They radio would work correctly from time to time. Service dept said it would have to replace entire dash system. Then noticed rear door/tailgate would not open as a door, next the tailgate stopped functioning all together; this makes the rear part of the xuv useless and dangerous. Dealer stated that is electronic and that all tailgate/rear door hinges rusted due to water coming in where rear window is/ estimate is over $650. 00 and it would happen again!!! next the driver's door will not unlock except by manual unlocking from inside and sometime the key will not unlock to driver's door. Key fob will not work on driver's door, tailgate/rear door; however, key fob works on passenger doors. Dealer stated that the tailgate/rear door issue has a history of this happening so why isn't there a recall???? when will GMC make this right???.

My car overheated on a normal day, about 80 degrees outside. I checked and replaced a defective thermostat, and started the engine only to find it misfiring badly for the first time. I gained advise from a local auto store and changed my spark plugs. When I pulled out the old ones, I found three of the six covered in oil. Upon further research, I was instructed to remove the manifold and replace the tube seals but the plastic manifold cover would not come off as indicated in a gm mechanics manual. This is the last of several problems I've had with the 2004 GMC Envoy xuv 2wd inline 6. I see many complaints on the oily spark plug issue and cracked manifold but no tsbs. Last year, I had my a/c compressor go out and replaced, my gas tank leak and replaced under a 'special warranty', a diagnosis that my heater core is bad, all three motor mounts go out and replaced, and a number of various small electronic components go out. I need GMC to correct these issues outstanding with my vehicle and expect appropriate action from them. I spent well over $40000 for this vehicle and its not even 10 years old yet. Gm has been well known for long life of their engines and body frames, and have said so on their behalf. They need to live up to the reputation I have so loyally painted for them.
