2004-Present Platforms
Although GMC has worked to remedy the problems that the Duramax engine has experienced through the years, the newer platforms still face common issues inherent within its predecessors. Lind has suggested that owners take the time to examine the entire system before making any decisions on the necessary repairs, and become educated on how the system works before taking the truck to a shop.
Some of these issues are devious and may show up as one problem, but could be something else entirely. Duramax drivers should always be on the lookout for these common problems, and address any issue—no matter how insignificant it may seem—as soon as possible. Taking care of the minor details could be the difference between a small expenditure and a serious financial investment.
