My 2006 Chevrolet 2500 hd diesel has had a vapor lock on the fuel filter @ least 3 times in one week. When it happens the vehicle just shuts down. This is very unsafe as you have very little or no breaks and steering. Just missed a car the first time it happened because I could not steer out of harms way fast enough. The second time I just missed a pedestrian in a parking lot. I just could not imagine what would happen the freeway.

Started my truck up on May 04 2010 and noticed fuel gauge showed empty. I had just filled it up the night before. Took it to my dealer and he determined it was a bad sending unit. My truck had about 16000 miles on it. Turn the problem over to GM with no satisfaction. I then checked the internet and found several problems of this nature. When the repair people took it in for repair they found extensive corrosion and other parts had to be replaced to the tune of $900. I feel this is defective equipment and GM should be responsible.

My Chevy diesel pick-up truck dies for 2-3 seconds when driving at medium speeds (50mph) and I floor the throttle. 2 dealers have told me this is normal, it is a lag due to the turbo. Everyone else I talk to that has this truck tells me they have the same problem. However, Ford and Dodge diesel trucks with turbos do not have this problem unless the turbo is defective. Also I have been told by some people who add a chip and adjusted such things as shift points etc. This problem goes always in 45 years of driving many vehicles I have never encountered such a safety issue. This needs to be corrected.
