2023 Chevrolet Silverado 3500

Engine started running extremely rough shaking vehicle. Various warning lights lit up. Took vehicle to dealer and was told that I need a new duramax engine because the cylinders are scored. Vehicle has about 58k miles It has been at the dealer for 3 weeks and they say they have no idea when they can get it fixed. It is my only work vehicle and now I have to rent another vehicle to keep working.

The 2023 Chevy High Country Diesel vehicle for 89,000 has failed tremendously, without any warning whatsoever. I've had my vehicle serviced on a 6 to 8 weeks bases at the dealership. on March 28, 2025 I was driving in SD and the truck just failed all the suddenly. The information stated to shift to neutral and restart which I did. The truck never started and had to be towed. The first diagnosis was the high pressure fuel pump which contaminated the entire fuel systems with metal shavings. Thereby, the CP4 failed and damage all components of the fuel system costing 11,750.00 for the repair. In addition to this, during further inspecting the shop informed me the engine camshaft and lifter were also an issued and contributed to the dilemma. I then got General Motors involved informing them that now way possible this should have transpired with a new truck having only 126,000 miles. I stated this is nothing for a diesel engine and something was not adding up. At the time I wasn't aware of all the issue General Motors were having with the trucks and suvs. I told them that no way can I pay 31,000.00 for a repairs on a new practically new truck I purchased brand new. They need to honor these problematic vehicles.

We bought a Chevrolet Silverado from 2023 as a new car in October 2024. It is an imported vehicle, as we live in Germany. After 7146km we broke down on the highway on [XXX] with engine damage. There were no signs or warnings beforehand. The Chevrolet simply stalled while driving and indicated that the start/stop button should be pressed. However, this had no effect. The whole vehicle came to a standstill. Not even the wheels were still rolling. A call to the seller (GeigerCars in Munich/Germany) immediately revealed that it was probably engine damage, as the problem is known. The vehicle was then towed to the seller's workshop and has now been there for over 5 weeks without spare parts, as according to the seller these are not supplied by GM. We have not yet received a rental car or anything similar and have to rent a car every week at our own expense. We have not received any help so far. A lawyer has already been called in.
