| Gmc envoy xl - 2006 has powered down three times while driving on a major interstate at approximately 65 mph during rush hour traffic. no warning lights prior to the power down. the vehicle slows to 15 within about 60 seconds. the first time, in approximately 2008, i was able to pull over two lanes to the breakdown lane and the power came back on while i was still coasting. i was told by gmc that without the light on they couldn't do anything. the second time in early 2012, the same thing happened during rush hour - there was no breakdown lane. when i went to gmc the light went off. i was told that i had a useful life of the car and it was getting old (135,000) miles and i should replace it. they said they could not do anything. it happened again last week on the interstate. i brought my car to my regular mechanic, non gmc, who coordinated with another gmc dealer for me. they fixed some codes they said were a problem. it happened again after having the car for 2 days. they fixed it again. we don't know if it's really fixed. this is a huge problem. gmc has no idea what they need to do to fix this. i have not seen service bulletins that relate to this. powering down to a speed below minimum speed on a major highway is very dangerous. i do not trust this vehicle and feel very unsafe in it. somebody needs to do something about this. *tr | |||

| Vehicle has been losing voltage when car is started and in idle position. when car is driving the voltage is always reading ok but when your at a stop light then all the instrument lights dim and the battery gets down to 10 and sometimes the car starts to stall. brought the car to darcy motors in joliet, il and they said its normal and the envoys experience this. i don't believe this and the car is 3 yrs old and has 80k for miles and its been running fine up until the past 2mo since we have been experiencing problems. we even went to sears and purchased a new battery and it still has the same problems. i brought the envoy to autozone and pepboys and both places checked the alternator, battery and all cabled and connections and all tested good. i don't know what the problem is but gmc needs to resolve this issue asap. *tr | |||
