(1) time. It appears that this failure is guaranteed to happen. (2) the fuel solenoid driver fails; the diesel engine stops; one is left going down the road without power steering nor power brakes in a very heavy vehicle. Whether an accident occurred is by chance. (3) a new, and expensive, fuel solenoid driver was installed. The old one is still in place.

Own a 1999 Chevrolet Suburban 6.5 diesel engine, w/145K miles, SUV was running ok but the last few months engine stalling and stop without reason, took SUV to a repair center, diagnose with fuel injection pump failure, Chevy dealer explained this is a well known defect, fuel injection pump has an electronic component (pmd) located on the side of the pump when engine gets hot sent failure signal to the main computer. Contacted GM customer service to verified/understand the issue, answered that yes indeed they agreed about the problem also said they had "campaign" not a recall to fix the problem but they didn't make this announcement to the public. I asked for help to fix the problem was told that I run out of options only honor this problem for 10 years or 120K miles? I was not aware and never received a letter from GMC. This is a potential accident waiting to happen with terrible consequences, imagine if the engine stops or stall going down the hill in any urban or rural area; passing another car in a busy highway and stalling or just the engine quit running (frontal crash!!); crossing a busy intersection with school kids inside and no power (horrible accident with serious injuries or perhaps casualties!!); towing a camper or boat on a busy and fast highway and suddenly stall or stopping in front of a semi-trailer; crossing a rail road and stalling in the middle with people inside a train coming its way!!. these are a few consequences this failure can created, imaging a lawyer jumping on this issue with a "lawsuit" and trying to blaming on you guys!! while this is a factory failure and poor design. I had replaced the "pump module drive" (pmd) and after spending over $1000 still have the same problem. At the present time I am not driving the Suburban until I hear from your Agency to see the results of your investigation. Hoping you will take care of this matter in a serious manner, I just want to thank you in advance for your help. God bless.

Vehicle is a 1999 Chevrolet Suburban K2500 with GM 6.5 liter turbo-diesel engine. The vehicle stalled in interstate traffic (I-270) multiple times on October 21, 2003. I called the dealer, and was informed that the likely cause was the electronic fuel injection pump, which GM has warranted for 10 years or 120,000 miles. The dealer thereafter replaced the injection pump under warranty. While I am pleased that the part was replaced at no cost to me, I believe that this represents an unacceptable defect. GM is obviously aware that the part is defective, or it would not have agreed to replace it for free after the rest of the vehicle warranty had expired. In this case, there was no harm, but these engine are often used in trucks and large SUVS that are designed for towing and hauling. For example, we purchased this vehicle to tow a horse trailer that is weighs over 5000 lbs. When the vehicle stalls, it loses power steering and braking. The potential for disaster when towing a large trailer is very high, and the stalling occurs without warning.
