They haven’t been on the market that long, but some customers have noted a problem with the hill start assist feature on the 2011 Heavy Duty Chevy Silverado and GMC Sierra. The hill-start assist, which is integrated with the trailer brake control function is designed to apply the brakes for an additional 1.5 seconds after the pedal is released, if the truck is parked on an incline of five percent or greater. However, there have been instances where it hasn’t engaged, instead the truck rolls as soon as brake pedal is released.

Not beating around the bush, GM quickly discovered that the problem lay with improper software calibration on the hill-start start system and is now issuing a recall. All brand new trucks will have the fix performed before they leave for the dealerships, while GM is actively looking at ways to get trucks already owned by customers back to have the software glitch corrected.

    That article about the "hill start assist" recall is interesting. I bought my 2011 K3500 in Sept and, thus far have heard nothing from G M. So having said that, I wonder if they could define "actively looking" when it comes to GOOD customer service?

    our 2011 3500 chevy silverado would keep rolling backwards when we put it in park on a small incline. We tried a few more times and eventually it stopped and we could leave it but put a block of wood under tire just in case. Our dealer said it happens sometimes on a cold start with hydralic fluid being trapped in line. Though the truck was running for at least 40 mins . Our dealer also said it was necessary to always use the emergency brake . Is this a recall problem or what? Can we have documentation as well because our dealer says there are no recalls on this truck.
