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.

Replaced with NEW OEM Part(s) - APP, Electrical Throttle Body and M15 Fuse - which did NOT fix issues and now due to safety concerns (further damage to vehicle and personal preservation) will be towing to dealership for diagnosis. Believe to be a known WIRING issues most likely due to WATER exposure/ SHORT in Connectors. - See IP, ECM/PCM and possible false activation to the APP circuit. This should be a RECALL due to the severity of mechanical issues of the malfunctioning system.
While hauling a trailer I received a warning tone and looked down to read the message, "reduced engine power", and the service engine light appeared all at the same time. The engine shutoff at the same time I received the warnings and didn't allow me to safely pull off the road.. I lost power steering, power braking, and controlling the vehicle and trailer while coasting to the sholder was difficult. Fortunately it was early in the morning and I was only traveling 35 mph on a straight road, and no other vehicles were on the road. If I was on an interstate traveling 55+ mph or on a curvy road it would have caused an accident or worse. I was very fortunate. This was the first time I experienced this problem and hadn't received prior warning messages or lights. The truck would not restart and the truck and trailer were towed to the dealership. The diagnosis was a failed "Fuel Pump Control Module." After waiting several weeks the replacement Fuel Pump Control Module did solved the problem. I kept the failed Fuel Pump Control Module and is available for inspection. Please investigate thoroughly! I was extremely fortunate the part failed when it did and I was able to walk away unharmed.
