This last weekend, was not towing, but on the road. We were doing about 60 mph and the truck bucked, speed dropped and could go no faster than 25mph! Pulled over at the next service station. Never got a service engine lite, called ONstar for an engine diagnosis and nothing showed up either. I Shut down and restarted. Was able to climb slowly to about 50 mph, if I would accelerate, the truck seemed to want to die. I thought it was the turbo.

Took it to the dealer and they found the problem right away, the fuel filter was just about plugged! This filter was about 10 months old, probably under 10,000 miles.

Has anyone with a diesel experienced a bad fuel filter before? Any symptoms like what we saw?

If we were on a long trip towing this would have been a big problem. I have learned a hard lesson here. The dealer charged me $115.00. I will be more aggressive with fuel filter maintenance in the future especially when we set off for a major trip. Probably will carry a spare with me from now on.

Are diesels more susceptiable fuel filter issues than gassers?
