I own a 2021 Chevy 3.0 duramax Mileage 21000 Truck stalled on by-pass Took it to local Chevy service center. They checked it out the next day and said truck had contaminated fuel. They showed me the fuel filter and it had ruptured and let contaminated fuel into fuel system. They told me since the fuel was contaminated that the warranty did not apply. I told them that since the fuel filter failed they should be responsible for the contamination to the rest of fuel system. I told them that I would be willing to pay for fuel tank and filter housing cleaning. They again said no. They gave me a quote to repair and it was about $12,000.00 I also drive a 2017 Chevy 6.6 duramax for work. 126,000 miles on it with no warranty Two months ago the very same thing happened to that truck and the company had to pay $9000.00 for that repair. I have another truck 2006 Chevy 6.6 duramax with 180,000 miles with never any issues. I definitely think you have a flawed fuel filter system on both the 3.0 and 6.6 duramax. Please respond
