What the bulletin says

This may be due to the suspension sensitivity of the vehicle. To correct this condition, follow the Service Procedure to replace the standard and reinforced rear caliper bushings and apply Kluberpaste to the machined surfaces of the brake caliper and caliper support bracket.

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 7 model years this bulletin names have filed 4,182 complaints with NHTSA since 2015. 978 of them name Power Train, Service Brakes — 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 2020 Ford Escape, the 78 owners who gave an odometer reading for Power Train reported it at a median of 46,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
In three occasions the automatic transmission has stopped working, operating under normal city driving conditions. Turning the car off and on again, it has worked properly. The car has less than 4000 miles. I took it to the Ford repair shop and there is a defect in the hybrid transmission, and it will take 4-6 weeks to be solved.

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 23-2308 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 23-2308 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.

The manufacturer filed it against 7 model years: 2023 Ford Bronco Sport, 2022 Ford Bronco Sport, 2021 Ford Bronco Sport, 2023 Ford Escape, 2022 Ford Escape, 2021 Ford Escape and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
