Filed Mar 31, 2026 · Engine, Fuel system · CA

11/26/25 at 85,400 miles on the v8 6.2L L86 engine, I began experiencing rough idle, loss of engine power and propulsion, a ticking/ knocking noise at idle and when RPMs increased as well as blinking engine warning light. Diagnostics/Repair work was done by Reliable GMC/Cadillac of Roseville to fix an ignition coil that was giving the engine error code. 2/24/26 At 86,697 miles, I began having rough idle worse than before, loss of power when accelerating and driving, knocking sounds that increased with acceleration in RPMs as well as a blinking engine warning light. All spark plugs and wiring were changed by Cadillac which resolved engine error codes for misfire. Diagnostics/Repair was done by Reliable GMC/Cadillac of Roseville. 3/30/26 at 87,246 (only 549 miles since the previous work up,) the car began to idle rough, and have a audible rhythmic tapping and knocking when accelerating and increasing RPMs. During driving, I experienced flashing engine light, and then sudden loss of power and control of vehicle. 3/30/26 Veh towed toThompson GMC, of Placerville, CA diagnosed vehicle with full engine failure from broken connecting rods and crankshaft of engine. Dealership is recommending full engine replacement, costing approx $23,000. This engine failure occurred on XXX in [XXX] …a dangerous, steep and curvy 2 lane highway. The engine light and loud forceful knocking happened almost simultaneously, without warning. I was forced to perform a dangerous maneuver to exit the highway into a gas station. Had I not done so, the engine failure could have caused full control loss of the vehicle. Traveling approx 50-65mph with my wife, [XXX] son and 2 daughters, an engine failure put my entire family at risk of serious injury or death. Had I not acted quickly, the outcome would have been catastrophic if not fatal. The vehicle is currently at Thompson GMC, [XXX] and available for further inspection. We believe this may be related to the federal safety agency EA25007. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA)

My wife was driving our 2019 Cadillac Escalade to work when the vehicle check engine light came on and started to smoke and shake violently. She avoided injury but the car was not drivable. A local independent service center said that the car's cylinder #1 was full of fuel, the spark plug was wet, reported loud bottom end engine noise and that we replace the engine. This appears to be the same issue that sparked the recall of 2021-2024 models. We have proceeded with ordering a replacement engine as a result. The old engine will be available for further inspection if necessary. There were no warning signs prior to this incident.
