The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. 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 59 model years this bulletin names have filed 14,878 complaints with NHTSA since 2015. 2,131 of them name Electrical 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 2021 Ford Bronco Sport, the 66 owners who gave an odometer reading for Electrical System reported it at a median of 41,426 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Check engine light came on at 24k miles. Alert on Ford Pass app said the engine wasn't heating up to operating temperature fast enough. Had a second Alert come up the next time I drove the car saying there was an electrical issue in the vehicle causing anti lock breaks and other important driver assistance features to not work including…

2019 Lincoln Nautilus · Electrical System · filed with NHTSA Jul 17, 2020
The collision warning doesn't warn sometimes. Nothing goes off when Im approaching and or have slammed on my breaks to avoid a collision. Sometimes it goes off at a great distance when it doesn't make sense to go off. I just bought the car used and have noticed this a lot. Also sometimes lane departure corrects and sometimes it doesn't.
2020 Lincoln Navigator · Electrical System · filed with NHTSA Sep 2, 2025
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 Ford TSB 23-2307 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 TSB 23-2307 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 TSB 23-2307 cover?
The manufacturer filed it against 62 model years across 2 brands (Ford and Lincoln): 2023 Ford Bronco Sport, 2022 Ford Bronco Sport, 2021 Ford Bronco Sport, 2021 Ford EcoSport, 2020 Ford EcoSport, 2020 Ford Edge and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
