Tl the contact owns a 2001 GMC Sierra 2500. While driving various speeds, the engine suddenly lost compression and the vehicle failed to accelerate properly. The vehicle was taken to courtesy Cadillac (1345 evangeline thruway, broussard, la) where it was diagnosed that one or more fuel injectors were faulty and remained open. The vehicle was not repaired. The manufacturer was notified and did not assist. The contact indicated that all eight fuel injectors were previously replaced approximately five years; however, but the failure recently recurred. The failure mileage was 200,000.

I have owned my 2001 GMC Sierra 2500hd truck since it was new. The vehicle currently has approximately 92000 miles on it. With the brake line problem I recently had I figured I should report the other issues that I don?t think I should be having with a vehicle that is less than 10 years old. The oil cooler lines and the transmission cooler lines have all rusted through and have had to be replaced. Along with the lines, the connectors for the lines have all had to be replaced due to catastrophic failure (they rusted so bad that were falling apart). If the vehicle was 20 years old I might expect this problem, but not on one less than 10 years old and the mileage that it has.
The engine died on me in a parking lot and wouldn't restart for about 15-20 minutes. The second incidence was the same. The third incident, it stopped on me as I was coming off an exit to get on the highway. I had just reached 50 mph when it cut out. It would not restart for 15-20 minutes. The next and final event before reaching a resolution to the problem. . . The truck cut out as I was on an extremely dangerous and busy section of highway doing 60 mph. I thank god it was a straight stretch or something fatal could have occured. In between each of these events, I took the truck to the mechanic and tried different oxygen sensors and other repairs that I was told wasn't a problem but I had no other explanation for what happened. There were no codes thrown for the mechanic to go by. After the last event on the highway, I took it to the dealer and told them I would not except the truck back until they knew what it was. After much arguing, they agreed to replace the crankshaft position sensor upon my request. They said it was not throwing a code for that and they couldn't guarantee it wouldn't break off during repair and result in an even costlier repair. I didn't care at that point and told them to do it. I had read many other reports on mechanic sites about this sensor being recalled on some but not all GMC 2500 hd trucks so I insisted the dealer replace mine. Mine did not fall under the recalled VIN# so it was out of pocket for me! it fixed the problem. I have not had a problem since and it's been 2 years now. I am still upset at the lack of agreement about extending the recall on this issue to other VIN#'s. This was a known problem that could have gotten not only me killed, but my 2 young sons who ride with me everywhere. I am very angry at the makers! nothing will fix that. Ever.
