Lincoln Engine Recalls Address Fire Risks and Loose Motor Mounts
⚠ 3 carry a park-outside (fire risk) advisory.
Engine compartment fire is the recurring concern across Lincoln's supplied engine notices. Certain 2021 Navigator vehicles may experience a fire while driving or parked, even with the ignition off; a separate notice identifies battery junction box short circuits on certain 2020 Navigators. Certain 2015-2019 MKC vehicles have a battery monitor sensor that may short-circuit and overheat. Two Corsair notices cover certain 2021-2023 vehicles with 2.5L HEV or PHEV engines, describing oil and fuel vapor released after engine failure near ignition sources. The May 2025 notice specifically covers incorrectly repaired vehicles. A separate 2020-2021 Aviator notice concerns motor mount fasteners that may loosen and lead to loss of power.
Warning signs to watch for
- May 2023 Corsair engine fire recall: unexpected engine noises, reduced vehicle power, or smoke.
- May 2025 Corsair engine fire recall: unexpected engine noises, reduced vehicle power, or smoke.
Can you keep driving? What the notices say
Three notices require parking outside: the May 2022 Navigator engine fire recall and September 2025 Navigator battery fire recall specify separation from structures and other vehicles; the May 2023 MKC battery sensor recall specifies separation from structures. Each instruction lasts until repair. The May 2023 and May 2025 Corsair engine fire notices advise parking and shutting off the engine as quickly as possible upon unexpected engine noises, reduced power, or smoke. Otherwise, those notices do not tell owners to stop driving. Neither does the December 2020 Aviator motor mount notice.
What the free repair involves
Navigator notices specify battery junction box inspection and replacement as necessary, plus ground-wire removal. The MKC notice specifies adding an in-line fuse, free of charge. The May 2023 Corsair notice specifies engine long-block replacement for 2023 vehicles. The May 2025 Corsair software update and Aviator motor mount fastener replacement are expressly free.
