The engine of my 2002 GMC Envoy has stalled twice in the last month while I was driving the vehicle, both time jeopardizing my safety. The first stalled happened while I was making a left turn at night. It stalled and stopped while I was in the oncoming lane on a bend where traffic speed in 75 mph. Luckily no oncoming traffic came before I pushed the car off the road. The engine finally started after about 10 ignition attempts. The second stall happened on the freeway while I was drive at 65 mph. The engine just shut down. I steered to the side of the road. The engine started after I let it rest a minute. 've took the car to a GMC shop after each stall. The first dealer told me they couldn't find anything, that it was probably bad gas. The second dealer said they couldn't duplicate the situation so they can't diagnose the problem.

While passing another vehicle we lost engine power, no acceleration power, foot had gas pedal all the way to the floor. We were facing a car head on and a ravine on the left. The car we were passing realized there was a problem and we were able to manuver back into the right lane without being hit. We stopped and waited and then tried to restart and was able to have engine power and gas return. I called the dealership and they first told me it must have fixed itself. I was really afraid this would happen again and requested they take the vehicle and run a computer history to see if it stored the code. They confirmed that the throttle body was defective. Dealer replaced. I reviewed your website and see all of the same complaints about stalls, engine failure, no acceleration. I contacted GM and requested they take my vehicle as trade in on 2003 Yukon that had 2500 miles but, was comparable to my 2002 Envoy. I would be back in a 5 year note but, I would feel much safer. The GM complaint clerk I was assigned told me there was not anything he could do because my vehicle was repaired and still under warranty. But, he called the dealer and told them he would allow me a $1000 cash voucher to use toward the purchase of a new vehicle. I did not ask for a new vehicle, I was willing to trade for the 2003 but this is a slap in the face. They didn't even want to give me the trade in value on my Envoy. I would have then been upside down in a vehicle loan. This is the worst service and treatment I have ever received. These vehicles are dangerous..just look at the complaints for the same problem. We were so close to being killed!! do something! I really hope you will do something to help the consumer before someone does die. (this veh was in the dealer in July and I complained then that I was getting 14mpg in town and 18 on the hwy. They tried to sell me an engine flush. I no longer feel safe in this vehicle.

Engine has to be replaced much hastle.

- Dillon, CO, USA

Engine stalls for no apparent reason. I have contacted dealership and they can find nothing wrong. I advised them of a recall regarding the fuel system that may affected the problem. Says they replaced the fuel filter. The first time I took it in, they said that it was the ignition switch. Also transmission makes a very loud noise when attempting to take off at times. It sounds like an engine fan that will not go off. There is a major lost of power when this problem is occuring. I bought this car as a program car, with @ 11, 000 miles on it already. I've had problems with it from day one. I have only had it a few months. I am extremely irritated with this engine problem. This is extremely unsafe.

*April 3, 2002  I took a co-worker to lunch that afternoon when upon returning to our place of employment the vehicle stalled without notice. I was traveling southbound on route 17 in allendale, which is a divided highway. All power to the engine was lost, including control of the acceleration, anti-lock brakes and power steering. I was able to coax the vehicle into the company parking lot but was unable to restart the vehicle. 6, 2002  I was on my way home that evening and the vehicle stalled without notice. I was traveling northbound on booton rd in Lincoln park, with is a four-lane road. All power to the engine was lost, including control of the acceleration, anti-lock brakes and power steering. I was able to coax the vehicle onto a side residence street but was unable to restart the vehicle. 9, 2002  I was on my way home that evening and the vehicle stalled without notice. I was about to turn onto booton rd in wayne and was completely stopped at an intersection. Prior to the light change, the engine stalled and I was unable to restart the engine. As a result I was blocking an intersection that was an outlet for route 23, a divided highway. After 20 minutes, the police came and blocked off traffic behind me. I subsequently had the vehicle towed. 11, 2002  I was on my way to a car wash in wayne after picking up the vehicle that morning. I had traveled approximately sixty miles from the time that I picked up the vehicle. I was next in line to receive a car wash and the vehicle stalled without notice. All power to the engine was lost, including control of the acceleration, anti-lock brakes and power steering. 24 - I was traveling South on NJ turnpike to newark airport. I stopped to collect the toll entry ticket when the vehicle stalled. I pushed the vechicle to the 'unprotected' center median, between two lanes of opposing traffic.

When the car had 4500 miles, the engine stopped running when I was driving at 40 mph -- there were no warning signs or other problems beforehand. The car would not restart immediately - nothing happened when I turned the key -- then, after 45 minutes it started but the engine was very noisy and power to accelerate was very poor. The dealer fixed the noisy engine by recalibrating the PCM but they said no fault codes were registered in the car's computer so they can't figure out why the car stalled. I advised them about NHTSA recall campaign # 02V121000 fuel:fuel filter line where the symptoms were very similar to mine. They said there was no GM recall and there was no problem with my fuel filter fitting. The stall occured on 5/14/02 and I have driven 600 miles since then without incident. I called the GMC # listed in the recall notice on 5/24/02 and they said no recalls applied to my car (which was mfg'd in 9/01) and they had no knowledge of the NHTSA recall campaign # 02V121000. I'm concerned that whatever caused my car to stall while driving will reoccur and it is dangerous trying to pull over across traffic lanes to the shoulder without engine power or power steering.
