2024 Duramax Diesel Problems 2024. The truck's l5p duramax diesel engine received a substantial bump in power and torque thanks to a stout list of upgrades, including a new turbocharger, improved piston. Last night while driving home, the engine started bucking at 45mph.

For the past week, my tailgate has been opening by itself while i am on the road. Anyone know what’s going on with the new trucks?
