2018 Chevy Silverado 2500Diesel Duramax (63,000 miles & Garage kept) While pulling 37' camper on flat terrain, Push Rod bent and broke in half - violently shaking and missing; Engine was ruined. Engine light did not appear until after it started shaking. Luckily this happened before crossing over steep mountain where we would not have been able to get off road or control vehicle and camper behind us. Truck was towed to Chevy dealership; had to wait until 10 days to learn extent of damage. Repair cost was going to be $26,000 and though our truck's trade in value was $37000 before this event, we were offered just $12000 for trade in. Though we had been led to believe that a Chevy Duramax was highly regarded for durability and longevity, we decided to purchase a RAM Truck. NO MORE CHEVYS for us! Contacted Chevy Customer Assistance but because we traded, they would not offer any financial assistance because we took the dealership's offer and traded the next day. We just couldn't stand a $26000 hit on an 8 year old vehicle and had to absorb that amount with our trade in.

Bought this truck brand new in september 2018 and have been having problems with the torque converter since the day we bought it. It has frequent moderated shuddering and or lurching at the acceleration speed of about 30 MPH. Almost everyday and several times per day. I have taken it to the dealer several times, they say there is a "flaw" in the 2017-2018 trucks but there is not a fix. They say to drive the truck in tow haul and that helps. I do not want to drive in tow haul, I feel it is hard on the truck to drive in tow haul on a regular basis. Tow haul is specific for towing. And it compromises the fuel economy. I am unhappy that there is a known problem but no fix with the torque converter.
