NHTSA 5-Star Safety Rating
Complaints about the 2021 Lincoln Aviator are spread across several systems, with no single dominant failure standing out at high volume. The most-reported category involves the back-over prevention system, where owners describe the vehicle braking unexpectedly while driving, not just while reversing, with the dashboard displaying a message about brakes being applied and power being reduced. A handful of engine and structural complaints round out the top reported areas, though complaint counts are low across the board. Structural reports include front suspension noise and ball joint boot failures. A few owners also mention electrical nuisances, such as interior reading lights cycling on and off randomly while driving. Window regulator failures appear in isolated reports, with both driver and passenger sides described as getting stuck in the down position.

By System
The 2021 Lincoln Aviator has 28 recalls, the most serious involving steering knuckles that can fracture and cause a sudden loss of steering control, engine failures that cut drive power without warning, and a high-voltage battery defect on plug-in hybrid models that can lead to fire or loss of power.
The engine concerns cover two related issues: intake valves in 2.7L and 3.0L EcoBoost engines can break and cause the engine to fail, and the low-pressure fuel pump can fail and stall the engine while driving. On plug-in hybrid models, a prior repair attempt for the battery defect did not fully resolve the issue, and a separate recall addresses vehicles that were incorrectly repaired under that earlier campaign. There is also a risk of fire on 3.0L gasoline models where a wire harness can contact the air conditioning compressor pulley and damage wiring. A loose motor mount can allow the axle to disconnect from the engine and cut drive power.
Occupant restraint recalls cover several areas: seat belt anchor bolts at multiple seating positions may be loose and fail to hold during a crash, curtain airbag attachment welds can break during deployment causing the airbag to deploy incorrectly, and the second-row easy-entry seat switch can cause seats to unlatch or fold unexpectedly while driving. Rear suspension modules with mismatched components can affect handling and braking. Rear door window bar and C-pillar trim can detach and become a road hazard.
Several recalls address rear visibility: the backup camera or 360-
