NHTSA Complaint #11648704 — 2023 CHEVROLET TAHOE

Vehicle broke down on 12/1/2024. Had it towed to the nearest dealership. Dealership claimed that gasoline was pumped into the tank. We knew that wasn't the case. I called the store we last used for fuel and spoke to the manager. She was able to pull my wife up on surveillance and verified that she pumped diesel fuel from a "diesel fuel only" pump on 11/21/24. We also verified that the fuel in the holding tank at the store was actual diesel fuel. My wife purchased 23.45 gallons of diesel fuel. The tank size on this Tahoe is a 24 gallon tank. We had burned half of this fuel before the vehicle broke down. We also verified that no one else had complained about the fuel from the store. Dealership said it needed a new engine. We had it towed to another dealership for a second opinion, but they couldn't verify what happened because the 1st dealership had cleaned out the fuel system. I called GM but they won't help because they are going off what the 1st dealership claimed. Vehicle is still under power train warranty, but they won't fix it. This vehicle left us stranded on the side of the road. Insurance was called and a representative did go and look at the Tahoe. He called back and said that the issue does not fall within our policy.
