2026 Chevrolet Silverado 1500 Engine Problems

“The first time I was driving in traffic and the truck shut completely off with no warning the display on the dash indicated,please put in park and restart, Took a straight to the dealership the code said it was a malfunction with a fuel pump. I had it for two weeks. September 27 it happened again. Took it back to the dealership and they’ve had it ever since.”

“I purchased a 2026 Chevrolet 1500 Duramax Deisel truck. At 9500 miles the truck started making popping and loud grinding noises and would shake while driving it. I barely made it to the dealership on August 6th 2026 I took it to Group 1 Chevrolet where I bought it in Houston,Texas and on August 8th was told that they need to replace the engine and do not have an estimated time for repair.”

“Driving on the interstate and the truck had a horrible vibration. It smoothed out and it did it again. I got off at the next exit and the engine was making a horrible knocking noise. I had it towed to my Chevy dealer for inspection. They drained the oil and found excessive metal in the oil. They decided that the engine needs to be replaced. The truck only has 4524 miles on it and it was purchased in June of 2026.”

“I started the vehicle in the morning, and noticed a knocking noise from deep inside the engine. Took the vehicle to the dealership, the knocking be turned into squealing and grinding and banging, check engine light came on, and vehicle died in front of the service department door. I’m an experienced auto technician and know that that was a connecting rod bearing knock. And now need a new engine on a vehicle with 919 miles on it.”

“No warning lamps or chimes. Truck shut down as I was pulling into my garage. Shifted to neutral on its own and a message on the dash said to put it in park and restart the engine. This event happened on 9/15/26. The truck has 1400 miles on the odometer.”
