Service bulletin SSM 51988

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2023 Explorer/Aviator vehicles built on 15-Mar-2023 and through 01-Sep-2023 may exhibit a vehicle vibration felt at 35-80 mph (55-130 km/h) in the steering wheel and/or seat. This may be due to tire flat spotting caused by vehicles being held at the Chicago Assembly Plant awaiting 360-degree camera repairs. Tire flat spotting on these vehicles may be a temporary concern that is resolved, with no repairs required, after the customer drives a minimum of 200 miles (320 km). Refer to Workshop Manual, Section 204-4A if diagnosis or repair is required after the vehicle has been driven this minimal distance.
