NHTSA Complaint #11676062 — 2021 CHEVROLET SILVERADO 1500

Around July 1st, 2025 I was hearing a ticking sound when taking off from a stop. On July 11th I had an oil change completed on the truck at the Local Chevy dealership, after the oil change, I mentioned the noise and was told maybe we could schedule some sort of deep cleaning of the internal components of the engine. After leaving the dealership after the oil change, I was still hearing the ticking sound. I then scheduled an appointment on July 22nd for the dealership to look into the ticking sound. I drove the truck to the dealership and it was working fine; other than the ticking sound when the RPM’s were at 2200. At no time was there any warning lights that came on to alert me to a problem. After approximately 30 minutes of waiting in the customer waiting area, the service advisor came and got me and said “we have big problems” and they were going to need the truck longer to look into it. I walked out to the service bay to get some personal items out of the truck. At that time, the mechanic pointed out some white looking fluffy cotton material and said that just came out the end of your exhaust. I had never seen that material prior to this appointment on July 22. The dealership called me July 24th and told me that the engine and exhaust system need to be replaced. They told me that the bottom end connecting rod came apart, and went through the engine and the exhaust system while it was at their facility on July 22. This truck has the 6.2L V8 (RPO L87) gas engine…. This truck is a 2021 and there is 76,957 miles currently on it (7/24/2025). With a blown engine, and an exhaust system that needs to be replaced.
