One problem related to ignition module has been reported for the 2000 Chevrolet Suburban. The most recently reported issues are listed below.
While driving vehicle at 40+ mph, the engine cuts off completely. Feel that this is a safety concern as the vehicle just "dies" and vehicle has to be guided to shoulder. First incident happened on interstate 95 n , just south of richmond, virginia, returning home with our 4 children. Found out later from a dealership that the 20 amp fuse called the ecm was blown. Since the first incident in may this problem has occurred 4 more times. We guide vehicle to side of road and replace the fuse, start the engine twice and we are on our way. At this time, the vehicle is at the dealership, hooked up to a "tech ii" computer for further diagnostics. Have informed dealership that I will not accept vehicle until this problem has definitely been resolved, as we are once again headed onto interstate 95 and may not be so lucky next time. Thanks for your time, please do not hesitate to contact me as we are very eager to get to the bottom of this potentially dangerous problem. Maryanne combs (703) 266-3173.
