NHTSA Complaint #11657999 — 2021 CHEVROLET SILVERADO 1500

On March 16, 2025 driving to church in Siloam Springs Arkansas it lost power while going down the road at 45 mph and we started hearing an oddly loud noise and then the check engine light came on. We limped it into the church parking lot. We came out from church and started the engine, there was no check engine light. We pulled out of the church parking lot and started down the road and we got up to 55mph when the oddly loud noise occurred again and check engine light came on. We pulled over and called for a tow to the dealership Superior Chevrolet of Siloam Springs. They found the engine was missing on cylinder #2 and the #2 connecting rod was bent. They found the lifter on #2 exhaust was broken. They inspected the cam and all the lobes looked good. They replaced the right bank of lifters and guides with all gaskets seals and pipes. Changed the oil and filter. Refilled the coolant. Test drove 10 miles and verified operation. It had 58,055 miles when this failure occurred. Our safety was at risk as a result of an immediate loss of power while traveling speeds over 40mph.
