NHTSA Complaint #11630322 — 2017 CADILLAC ESCALADE ESV

Subject: Engine Lifter Failure in 2017 Cadillac Escalade - Manufacturer-Acknowledged Defect Component/System Failure: My 2017 Cadillac Escalade has experienced a critical engine malfunction specifically related to the Active Fuel Management (AFM) lifter system. The lifters are causing multiple engine misfires. This issue directly matches the manufacturer-acknowledged problem detailed in GM Service Bulletin 15-06-01-002M. Safety Risks: The lifter failure creates significant safety hazards, including: Potential sudden loss of engine power while driving Risk of unexpected vehicle stalling in traffic Compromised engine performance and vehicle control Potential complete engine failure The manufacturer's service bulletin recognizes these systemic issues across multiple vehicle models, including my Escalade. Problem Confirmation: General Motors has explicitly documented the problem in Service Bulletin 15-06-01-002M, which covers 2015-2020 Cadillac Escalade models. This indicates a known, widespread manufacturing or design defect. Despite GM's explicit recognition of this critical engine defect, customers must pay for repairs out of pocket when the warranty expires. This places an undue financial burden on vehicle owners for a problem that is clearly a manufacturing defect.
