What owners reported
Source: NHTSA complaint databaseOwners of the 15 model years this bulletin names have filed 2,674 complaints with NHTSA since 2015. 1,610 of them name Engine, Electrical System, Fuel/Propulsion System — 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 2016 Acura MDX, the 54 owners who gave an odometer reading for Engine reported it at a median of 66,701 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Our Acura MDX has continued to have Auto Idle Stop issues since we purchased the vehicle. Sometimes the vehicle would not restart after being stopped at a traffic light. Most recently, an accident almost occurred when the vehicle stuck behind us at the traffic light tried to go around us while we were trying to get the engine started and…

The car does not restart after it has turned off during an idle stop. This is part of the start/stop system. The stop/start feature will leave you stranded at stoplights due to a failure to restart the car. To restart, you must put the car in Park mode and hit the start/stop button at least twice to turn it off, then turn on the car.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Acura BTI&03282022903 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 BTI&03282022903 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. Every Honda warranty extension on file lists the ones Honda has filed.
Which vehicles does BTI&03282022903 cover?
The manufacturer filed it against 15 model years: 2020 Acura MDX, 2019 Acura MDX, 2018 Acura MDX, 2017 Acura MDX, 2016 Acura MDX, 2020 Acura RDX and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
