We have replaced the front windshield twice now as it is very easy to crack on small road debris. I have other cars that do not experience this and it feels like the windshield was not designed well

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&04092025901 a recall?
No. A manufacturer communication 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&04092025901 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&04092025901 cover?
The manufacturer filed it against 8 model years: 2024 Acura MDX, 2023 Acura MDX, 2022 Acura MDX, 2025 Acura TLX, 2024 Acura TLX, 2023 Acura TLX and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
