2021 Cadillac Escalade ESV Complaints

My wife was driving my kids to their nana and papas house when the vehicle loss power. The vehicle started to have a knocking noise and started to vibrate towards the engine compartment. The dash lit up like a Christmas tree. We took the vehicle to a local mechanic and he suggested that we might need a tune up. We purchased 8 brand new spark plugs, spark plug wires and 8 brand new coil packs. The local mechanic installed all of the new parts and the vehicle acted just like it was before the tune up. We then took the vehicle to Boyd Cadillac in Henderson,NC. Tim, who is our service provider, contacted us and told us that we had severe engine failure. His recommendation was a complete engine install. We have used Boyd Cadillac, Tim on several occasions. We had an alternator replacement done which was not under warranty. We had lifters replaced under warranty around the 50k mile mark.

Since April 2025, my 2021 escalade has been losing oil quickly. No leak externally has been found. The recent recall found "no engine problems" and placed new thicker oil, but the leak continues with us losing significant amounts of oil every 500 miles. This engine remains defective, losing oil internally, and is putting 600,000 drivers+ at risk for engine failure or loss of propulsion. The recall has not solved the issue at all and the protocol to declare an engine OK and change the oil is insufficient.
