NHTSA Complaint #11658389 — 2021 GMC YUKON

I took my vehicle into the GMC dealer near my home in Beaver Dam, Wisconsin (Napleton) on April 30, 2025 to have the L87 engine recall addressed. I had a video with sound where a loud clacking noise could be clearly heard, coming from the passenger side of the engine. The service attendant and the mechanic assigned to my vehicle listened to it and both agreed that the sound was not normal, or good. Four hours later, they called and said the vehicle was ready to be picked up. They did neither pass or fail the engine, and didn't put in thicker oil. I was told that they aren't doing anything until they received clearer direction from GM. This is very disappointing for me and now afraid to drive on the highway for fear of catstrophic failure and potential crash. I called another GMC dealer nearby, in Watertown, WI, who said they weren't doing anything either with the L87 engines (year 2021-2024) until they recieve clearer direction from GM. I have taken my vehicle in 2 previous times to address the "clacking" noise, each time they say they hear nothing wrong.
