What component or system failed or malfunctioned, and is it available for inspection upon request? -My engine started to make a loud ticking and knocking noise. I brought it into Good Chevrolet in Renton WA 6/3/25 where they told me there is an aœinternal engine failure due to failure of the lifters.a When I asked the dealership for the repair estimate so I could possibly have a second opinion, they said they were aœnot comfortable giving their information and the problem in writing.a They refuse to give us any documentation but were insistent that even though NHTSA has issued a mass recall for this exact same issue on the larger engine in my same year of vehicle, aœitas unrelated.a How was your safety or the safety of others put at risk? -The engine is failing and had we not brought it in for diagnosis, I could have had full engine failure while driving with my children and been in a catastrophic crash. Has the problem been reproduced or confirmed by a dealer or independent service center? -Yes the problem can be reproduced and has been confirmed by Good Chevrolet. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -Good Chevrolet inspected the engine but refuse to give us documentation though they had us file a claim with GM (I will attach the claim email) Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -I noticed a small noise after I had fans replaced in September but the noise gradually increased so it was brought in for diagnostics. There were no warning lamps or messages.
