Date: June 22, 2026 Time of Incident: Approximately 11:48 a.m. Vehicle: 2025 Chevrolet Silverado High Country 6.2L V8 Current Mileage: Approximately 29,500 miles I am documenting the events surrounding the unexpected engine failure of my 2025 Chevrolet Silverado High Country. On June 22, 2026, at approximately 11:48 a.m., while driving at highway speed, the vehicle was operating normally with no warning lights, messages, or other indications of a problem. I began hearing a metallic clanking or knocking noise from the engine area. The noise progressively increased in volume and severity over approximately ten minutes as I reduced speed and looked for a safe location to pull over. My intention was to reach the dealership if possible; however, as I slowed to approximately 15 mph to make a turn, the noise stopped abruptly, the engine shut off, and the vehicle displayed a message instructing me to press the Start button again. The vehicle came to a complete stop at approximately 11:58 a.m. I attempted to restart the vehicle once, but it did not restart. No additional restart attempts have been made. There were no warning lights displayed prior to the engine shutting down, and there were no visible fluid leaks underneath the vehicle after it came to a stop. The vehicle received a routine oil change on June 16, 2026, approximately three days before this incident. I have retained the service receipt and all related documentation. The vehicle will be transported by flatbed tow truck to an authorized Chevrolet dealership for diagnosis and repair under warranty. This email is intended to document the incident timeline and details while they are fresh in my memory. I have not heard back from the dealer yet.

We were pulling a 5th wheel camper on the highway at 62 mph.  We experienced a series of sudden breaking sensations.  Engine RPMs did not change during these events.  We had been traveling for 45 minutes and decided to cancel our camping trip and return home because we were afraid of getting stranded away from home.  The sensation felt like a sudden strong application of the rear brakes.  It was very momentary.  We turn around and shifted the transmission to "L" which limits the highest gear to 7.  We did not have any more incidents. When we were close to home we shifted back to drive and the problem returned.  We were concerned with a complete loss of control or motion if the problem got worse.  We have an appointment to have the truck looked at next week.  There were/are no diagnostics codes visible on the dash.
