On 5 separate occasions, the engine on my 2004 trailblazer has stalled while in traffic. 1 time, the engine stalled when I applied the brakes; every other time, the engine stalls while at idle. I have taken it into the dealership repeatedly, and they have been unable to duplicate but not fix the problem. They have replaced the manifold pressure valve and cleaned the throttle plates, but the problem still persists.

Major electrical problems inside the vehicle. I have owned it less than a year.the vehicle has been in the shop twice in the past two weeks. Exiting the freeway the I had a complete power failure. The vehicle completely stopped and locked up and there was a semi truck behind me! My vehicle was moving and in "drive" when this happened. I had two of my toddlers in the car with me! The vehicle was taken into a local dealer and unfortunately they could not find anything wrong with it. Apparently, when the vehicle is restarted it erases the codes in the engine as to what caused the problem. Well, it happened to me again this evening. Same problem. This will be my 5th time of bringing this vehicle in for electrical problems in less than a year. I only have 9400 miles on the vehicle and bought it brand new. I do not feel safe driving this vehicle with my 5 children as passengers. Is there a way gm can get me a better running vehicle? I paid a lot for this vehicle and am very unsatisfied with it's performace. There always seems to be something wrong with it. The connell chevrolet service here in killeen has been very helpful. I feel sorry for them because they did not sell me this vehicle but they are the ones nice enough to try and fix the multiple problems.
On the 1-2 and 2-3 shifts there is a rattling sound (or light knocking) sound coming from the engine. It sounds like noisy lifters. It occurs most of the time, but not all of the time.
Engine stalled in traffic and idles rough on startup. Dealer reprogrammed idle control module. Engine surges and shakes under a load from power steering or alterantor. Dealer cleaned throttle body (only 4800 miles) and found large leak at evap vapor pipe. Continued to have problem. Dealership contact gm for help. Gm replied that "4.2 liter motors have an inherent vibration at that speed." gm technical assistance also stated "engine surge under is normal under load by design." car is ticking time bomb for another stall in traffic and daily endangers my family.
