1 Seats problem

Failure Date: 07/13/2010

Out of nowhere my front head lights went out. Its not the fuse or the bulbs, both front low lights went out. The high beams work. There is no power going to the lights and I have to buy a new switch. I also had to replace the engine almost a year ago because the o rings went up. The gas gauge is broken and my passenger window will not go down. I feel so stuck with this car!.

2 Seats problem

Failure Date: 01/01/2007

Repeat problems since car was purchased brand new at dealers. Air /O2 sensors defective/replaced. Defective fuel pump/fuel sensor/electronic gas gauge; flickering/dimming headlights; freezing/inability to control driver's side seat and controls. 1/4 of front instrument panel lights out; drivers side seat control lighting 1/4 out; check engine light and low fuel light on continuously since 1997. Tie rods both replaced as well as both front sway bars. Immediately following vehicle purchase, check engine light would continuously go off. I would call onstar at which point I was told to take car in for repair w/I 7-10 days (often told a problem w/powertrain or transmission) . At dealers service dept, told over and over again after tons of worry, concern and time spent, that electrical system on this car tends to trip/trigger check engine light and they would just reset it so after awhile, I began to disregard the light as I was in the dealership almost weekly. Approx 2 yrs after purchase, filled up gas tank and fuel light showed "low fuel". Went back up to full, dropped to 1/2 and back to empty. Went back to full after car was turned off and continued to do this. After about 2 weeks, constantly stays at empty. Called repair shop and was told approx $700-800 to drop tank and replace fuel sensor which I could not afford and began to track odometer and refill tank after 200 miles driven after fill up. Have been doing this for 5 years. Jan 29,2011, I go for emission test. Fail d/t low fuel and check engine light being on. Go to mechanic, approx $950 repair. Check engine light goes off. . . And back on next day. Read thousands of posts online and am finding many, many Envoy owners experiencing same problems as mine. These are safety issues and gm should issue a recall on entire fuel and electrical system. Please call for questions/clarification.
