The failure pattern owners describe
Owners consistently report engine failures on 2015 Cadillac Escalades, most commonly misfires and loss of power while driving at highway speeds. The most frequent complaint is a knocking or rattling noise followed by a check engine light and misfire codes affecting one or multiple cylinders. Several owners cite Chevrolet TSB 15-06-01-002F (Engine Misfire/Tick Noise) and question why no recall has been issued, especially given the safety risk of sudden power loss on interstates. Failures occur across a wide mileage range (53K to 201K), with many happening relatively early in the vehicle's life. Other reported engine failures include variable valve timing system failure, lifter and fuel injector failures, crankshaft failure, and complete engine seizure. One owner reports carbon monoxide fumes entering the cabin, resulting in hospitalization. Replacement engines are quoted between $17,000 and $20,000. Extended warranty coverage initially paid for some repairs, but later warranty companies declined coverage, leaving owners facing high out-of-pocket costs. A few owners note a loud grinding noise on cold start that dealerships claim is normal.
