Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 2,422 complaints with NHTSA since 2015. 504 of them name Electrical System, Air Bags — 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 2018 Tesla Model 3, the 42 owners who gave an odometer reading for Electrical System reported it at a median of 28,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

My wife was trying to park the car in our garage when the car suddenly sped up and hit our inner garage wall. It then reversed back and hit the wall a second time. Then it automatically reversed and parked on the neighbor's driveway. Both the sterling air bag and airbag near the feet deployed. The car's front was smashed.

Common questions
Source: NHTSA, 49 CFR 579.5Is Tesla SB19-20-003-R3 a recall?

Is the SB19-20-003-R3 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.
