“I have had several engine stalls on my 1998 6.5 chevrolet diesel engine. The engine will quit as if the switch is turned off at random times and driving conditions. The danger that this poses in highway traffic can not be under stated. When the engine quits I also loose the power steering and braking making this a very dangerious situation. Although I have not had a crash when this condition occurs, I have had several close calls and have read on internet web sites others that have not been so lucky. …”
NHTSA complaint #10093702, filed 2004-10, 111,468 miles“This is, as I have read elsewhere, a common problem with all GM vehicles using dexcool antifreeze.

The dealer insisted there are no service bulletins or recalls for this problem but, through my own research, I am finding that this is a common occurence with vehicles using dexcool coolant. …”
