We have a 1999 chevy suburban. It now has 80k miles on it. We are on water pump #5. It has always had coolant leak problems. It was always blamed on the water pump. Now I have been informed that the coolant is leaking from around the intake. Gm knows of this problem. It has to do with electrolisis between the cast iron engine block and the aluminum intake. We had an extended warranty through 72k miles, but this problem was never fixed. I would have a hard time convincing myself to buy another gm vehicle...

I own a 1999 chevrolet suburban k1500 with a 6.5l turbo diesel engine. I recently went through numerous instances where the engine shut off immediately as if the ignition were shut off. Several instances were not life threatening as they occurred in parking lots or not when in traffic. Several instances were more dramatic. When merging into city and highway traffic, I was suddenly left with no steering or brakes as the engine had died. This is a large heavy vehicle and does not respond well without power input from those components. Luckily none of the instances resulted in a accident. I now have a newborn son and always have a concern with him in the vehicle that another shut down could occur at any point. The vehicle was brought to the dealer and the injection pump was replaced. Doing research on this revealed countless incedents of similar occurances with vehicles having the same electronic injection pump. While fixing the problem temporarily has helped, it appears as if only a matter of time until it occurs again. Had I been aware of these persistant problems prior to purchasing the vehicle, I likely would have purchased another. As it is now, I am stuck with this dangerous issue.
