Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I am submitting this complaint to report a serious and potentially dangerous safety defect involving the internal water pump design in the 3.5L Duratec V6 engine used in my 2017 Ford Flex. The water pump in this engine is mounted internally behind the timing chain cover. When the pump fails, coolant is not externally visible but instead leaks directly into the engine oil. This design prevents early detection and warning, leading to rapid and catastrophic engine failure without adequate notice to the driver. …”
