What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2024 Nautilus vehicles may exhibit a condition with condensation in the rear body mounted or decklid lamp assemblies that does not affect the function of the lamp. This condition is currently under investigation and replacement of the lamp assemblies may not resolve this condition. Parking the vehicle outside in the sun over several days or in a warm garage may help dissipate the condensation. Continue to monitor OASIS for additional information and schedule service appointments for customers once a repair becomes available.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lincoln SSM 52321 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the SSM 52321 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does SSM 52321 cover?
The manufacturer filed it against 1 model year: 2024 Lincoln Nautilus. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
