Three problems related to alternator/generator/regulator have been reported for the 2007 GMC Envoy. The most recently reported issues are listed below.
The contact owns a 2007 GMC Envoy. The contact stated that the low beams failed to illuminate. The contact was not included in NHTSA campaign numbers: 13v248000 (electrical system and visibility), 12v406000 (electrical system and visibility) and 15v519000 (exterior lighting). The dealer also replaced the window regulator due to the windows failing to go up and down randomly. The vehicle was to be taken back to the dealer for further diagnostic testing. The failure mileage was not available.
My driver side power window / door regulator assembly cable frayed and the window would not move up or down until repaired. This happened to the driver side door window in August 2014. Now in March 2015, being 7 months later the same issue has happened to the front passenger side door window / door regulator assembly. I use this vehicle for less than 5000 miles a year, I feel this issue needs to be looked in to for the defect of faulty cabling / poor quality. This will be the second time that I will pay out of pocket for the same issue within a year.
February of 2014, gas gauge started to go haywire. After approximately 100 miles, needle of gas gauge goes to empty and low gas indicator light comes on. November of 2013, passenger air bag indicator light stays on. Does not matter if seat is empty or occupied. July 2011, right/front window regulator cable broke-replacement cost me $340. 00. At this time shop found that front differential case leaking. This was replaced at no charge. Have not owned a gm product in over 15 years, now I know why. Come on gm stand behind your products, no matter what year they were manufactured. You claim that your vehicles are on the road for years and years, really. . . Kind of hard to drive and trust a vehicle that does not function properly.
