What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as NHTSA’s summary states it — build dates and equipment as the manufacturer filed them. The dealer checks the VIN and the build date on the door jamb; a vehicle outside the window is not covered by this bulletin.
Certain 2022 Model Year 3.5L GTDI Equipped Expedition, F-150 and Navigator Vehicles Heavy Grey/Blue Smoke and/or Oil from Exhaust Tailpipe(s). In some of the affected vehicles, itâs possible the left-hand turbo oil drain hole was incompletely drilled during the engine block machining process. A vehicle built with an engine block that has an incomplete turbo oil drain hole may experience heavy gray/blue smoke with oil from the exhaust tailpipe(s), which could lead to a malfunction indicator light on the instrument panel cluster.

Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 958 complaints with NHTSA since 2015. 3 of them name Engine — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2022 Ford F-150, the 13 owners who gave an odometer reading for Engine reported it at a median of 12,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
At about 2:30am after hearing some popping noises I went to the vehicle and saw that the engine under the bonnet was on fire. The fire was seeping out from the sides of the bonnet. The vehicle had been parked since 9:20pm the previous night. I called emergency services including the fire department and the police.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford 22U08 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 22U08 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 22U08 cover?
The manufacturer filed it against 3 model years across 2 brands (Ford and Lincoln): 2022 Ford Expedition, 2022 Ford F-150, 2022 Lincoln Navigator. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
