Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2005 GMC Envoy Owner Comments

problem #3

Jan 252012

Envoy XL 4.2L

  • Automatic transmission
  • 93,432 miles


In the dead of the winter the blower fan for heater was working only part time and wouldn't work at all on the coldest days. I had no defrost or heat and was working to much to take time to get it fixed. I feel GM should refund me for this problem and anyone else with the same problem. If they don't something about this they may have lost me as a customer.

Envoy SLT 4.2L V6

  • Automatic transmission
  • 45,000 miles

The air conditioning and heater were working intermittently, and could randomly smell something funny like rubber burning or electronics frying for a few weeks. Eventually the blower motor stopped forcing air to the ducts, and would not work at any speed. The control module and resistors had to be replaced - the module cost about $72.00 and I was charged 43.50 for labor plus tax. Thanks GM, for not taking the time to build another decent component. Maybe this is why you're company is failing, people don't want to buy this junk!

I'm finally things going wrong with the 2005 Envoys, I think some of the items should be recalled, due to don't make any difference if you take very care of your car, this items will still happen.
