3.0 Duramax exhaust smell in cab

YakTownie22 replied to IcemanNY's topic in Engines & Drivetrain (V8, Duramax, TurboMax)

My 2020 AT4 has around 38K miles, and my warranty recently expired. I've noticed a faint exhaust smell over the past couple of years, attributing it to diesel quirks. However, it's becoming more noticeable, and I'm concerned for my family's health. Any chance GM or the dealer covers these fixes now that my warranty is over? I’m calling the dealership in the morning. Appreciate the insights and support from everyone on this thread! The work order and pics shared have been incredibly helpful. Thanks, all!
