NHTSA Complaint #11658100 — 2008 LINCOLN MKX

I am reporting a serious mechanical defect in my 2008 Lincoln MKX involving the internal water pump. This vehicle uses the Ford 3.5L V6 Cyclone engine, where the water pump is mounted inside the engine and driven by the timing chain. My water pump failed unexpectedly, causing coolant to leak into the engine oil. This design flaw poses a serious safety risk due to potential engine failure while driving. This could lead to the engine seizing without warning, loss of power steering and braking, and increased risk of a crash. Ford and Lincoln are aware of this issue, and many owners have reported similar failures, but no recall has been issued. Repairs cost thousands of dollars and often require full engine replacement. This is a known design defect that puts drivers and passengers in danger. I urge NHTSA to investigate and mandate a recall before someone is seriously injured or worse. This failure is unpredictable, dangerous, and affects many vehicles using this engine platform
