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.
When reaching 70 mph vehicle shut down without any warning. Vehicle had been reapired three times; however problem still exists.
Consumer states while driving at highway speeds the vehicle shut off and the brakes where not working nothing was working except for the steering, the consumer waited five minutes and then the vehicle started up again. Contacted dealer, the dealer found a loose engine control module.
My 2002 GMC Envoy lost all power three times at high rates of speed. The first time we had it serviced and I was told a module needed replaced. The second time, the car shut down at highway speeds but restarted approximately 15 minutes later but then the same thing happened again the next day while my wife was driving home from work traveling at 65 mph down a highway. We had it serviced again and this time I was told it was due to a loose wiring harnass. Car has had numerous problems since and it is an unsafe vehicle for my family to be transported in.
The engine shut down with out warning while the consumer was driving at 75 mph.
