Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Regularly maintained 2020 Lincoln Navigator at 78,000 miles experienced engine failure with no warning. No check engine light until we experienced power issues and engine shuttering. We took the vehicle directly to the mechanic within an hour of check engine light. They changed the oil and said to go to the dealer. Dealer assessed the vehicle as follows: Bottom end failure of the short block which caused a knocking noise. Confirmed metal debris in the engine oil. Seals failed and leakage occurred. Recommend complete engine replacement. This is the same issue occurring in newer models. …”
NHTSA complaint #11717154, filed 2026-02“Vehicle will abruptly lose power when accelerating to pass. Typically when travelling between 40 and 60 miles an hour and while accelerating to merge or pass. Vehicle basically stalls. Creates extremely dangerous situation.”
NHTSA complaint #11539842, filed 2023-08“Catastrophic engine failure on 2020 Lincoln Navigator at 93,000 miles. Oil contamination in cylinder 6 caused complete compression loss due to piston ring failure. The engine suffers from failed cam phases and excessive carbon build up which are known failure points of this engine. Ford Technical Service Bulletins 20-2423 and 23-2143 document this as a known manufacturing defect for vehicles in my build timeframe, proving Ford was aware of this problem before production. This is premature engine failure requiring complete engine replacement on a 5-year-old vehicle. …”
