NHTSA Complaint #11425273 — 2021 CHEVROLET TAHOE

The engine started knocking and running rough. My wife pulled the car over. She could tell from the sound it was not a minor issue. We had the 2021 Tahoe toed to Vaden Chevrolet in Beaufort, SC, where we purchased the vehicle. The dealer confirmed it was an engine problem. 8 lifters along with other associated parts need to be replace. This is a major engine repair. The vehicle is 8 months old and has approximately 10,000 miles on it. Doing internet search, the failure of engine lifters in Tahoes and Silverados appears to be a known problem. The service department manager told me that they have already done 10 of these this year. Failure of an engine while driving is a major safety issue. The vehicle is in for repair, now.
