NHTSA Complaint #11676295 — 2015 CADILLAC ESCALADE

My 2015 Cadillac Escalade suffered complete engine failure caused by a known design defect involving the Active Fuel Management (AFM) lifters and camshaft. This issue is documented in GM Technical Service Bulletins (TSB #15-06-01-002E and PIP5606C), which acknowledge lifter collapse, misfires, and internal engine damage in 2014–2020 Escalade and similar models. GM-certified dealerships repeatedly misdiagnosed the issue as minor (e.g. spark plugs, oil), allowing the underlying defect to worsen. I am uploading invoices from Cadillac of Cerritos (who misdiagnosed the problem), my trusted local repair shop, and Cadillac of Torrance, who ultimately diagnosed the failed lifters and camshaft, but had originally referred us to Cerritos because they could not take us at the time. The misdiagnoses delayed necessary repair, resulting in catastrophic engine failure and a repair quote exceeding $10,000. GM only offered $2000 towards a new car despite clear evidence of a widespread design defect. I believe this is not an isolated case. Many owners have filed similar complaints with NHTSA, and class action lawsuits (e.g. Mason v. GM) are pending for this exact issue. Despite this, GM has not issued a recall. This defect creates serious safety risks, including stalling, loss of power, and engine failure while driving. My family was placed in danger by a vehicle GM and its certified dealers knew was vulnerable. I urge NHTSA to investigate this engine defect further and require GM to take full accountability.
