Seven problems related to car stall have been reported for the 2006 GMC Envoy. The most recently reported issues are listed below.
Failure of the dod lifter, also known as the active fuel management system. While at speed on the freeway, the dod lifter on cylinder #7 failed causing a misfire on the cylinder which caused teh engine to shake violently. This is the 2nd failure of a dod lifter on my truck. In Nov 2014, a dod lifter on cylinder #6 failed, causing a engine misfire and a violent shake. The cause of the failure was determined to be lack of oil pressurize the dod lifter. Upon deciding to rebuild the motor rather than replacing the motor, we decided to replace all internal components of the motor simply because the motor would need a full tear down anyway. The lifters, oil pressure solenoids of the dod lifters, rockers, rocker arms, springs and camshaft were all replaced thinking that we might as well rebuild the block with new components to save off any future issues. After 1 month in the GMC service center, the vehicle was back on the road in Dec 2014. This repair was $5,900. 00 in March 2016, yes 14 months later, a 2nd failure of a dod lifter occurred on cylinder #7. The vehicle exhibited the same issues as in Nov 2014. This failure occurred on the rebuilt motor on new components installed in Nov 2014. This repair will cost $2500 just to replace the 1 lifter. No other components. This leads me to believe that a the dod failure is more common and is a design flaw of the active fuel management system. This issue is more than a TSB issue, it should be a recall.

In the morning the car run fine, but once the engine is warm and I start to run arons it stalls. If I wait about 10min or so. . . I must speed home or to a safe area to let the egine cool. If I come back in a few hours,the truck will start with no problem. It has been to the shop more often then I remember. Is there anyone having these same issues?.
On 12/23/13, while parked the vehicle died. When restarting, it was a little slow but did end up starting. On 12/24/13, I had the battery tested and it showed that the cca's just needed a good charge so I let the vehicle run for 45 minutes. A few hours later, the vehicle would not even turn over. On 12/25/13, removed the battery and reinstalled it. The vehicle started fine and ran well for a few days. On 1/1/14, vehicle stalled while driving. Ended up restarting but I had to give it gas to do so. On 1/2/14, I started the car to warm it up and it started fine. I let it run for 20-30 minutes before attempting to drive it. When I got in the vehicle, it said that the brake system was not working and the stabilitrack light was flashing on and off intermittently. I had to get a cab to work & have it towed to the shop. I'm hoping to hear back tomorrow in regards to what is going on. Also, had to get a rental vehicle in the meantime for transportation.

Also, on numerous occasions, the air bag light illuminated, and remained on for days. The consumer referenced recall # 06v417000.
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.
