Read by machine from the document NHTSA serves (5 pages), read Sep 30, 2026. A part number is shown only where it matches Audi’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 21 model years this bulletin names have filed 1,205 complaints with NHTSA since 2015. 8 of them name Visibility/Wiper — 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.
Panoramic roof glass exploded outwards while driving on the highway. No sign of rock damage or debris hitting. The glass is deformed outwards. The glass was sent towards the interior of the car. The sunroof shade was closed and many pieces of glass were caught by this otherwise the driver would have been hit by glass shards
2019 Audi SQ5 · Visibility/Wiper · filed with NHTSA Aug 30, 2024 · ODI 11611752
Two large windshield chipping in less than 3500 miles. Very bizarre considering the cost of the car. I own another vehicle, similar size (VW touareg 2012). It was hit many times and there are barely any marks left on the windshield. Is acoustic windshield (which my car is equipped with) less resistant to cracks and breaks?
2017 Audi Q7 · Visibility/Wiper · filed with NHTSA Dec 30, 2017 · ODI 11057683
While driving the rear half of the sunroof exploded. With no warning there was a sudden, very load "pop". The sunroof pane had completely shattered and was only held in place by the aftermarket tint layer that had been applied. The mesh shade that sits below the sunroof kept any pieces from falling on us while driving.

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 Audi A8723372055257_6 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 A8723372055257_6 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 A8723372055257_6 cover?
