What owners reported
Source: NHTSA complaint databaseOwners of the 10 model years this bulletin names have filed 732 complaints with NHTSA since 2015. 40 of them name Structure — 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 2019 BMW X3, the 14 owners who gave an odometer reading for Structure reported it at a median of 5,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
I was driving and had just entered into hwy. I was traveling approx 45-50mph. There were no other vehicles around, when I suddenly began hearing a popping or clicking sound, followed by what sounded like an explosion. I could hear glass shattering above my head, but was protected from injury because the sunroof shade was closed.

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW 6520900300 a recall?
No. A warranty extension 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 6520900300 repair free?
A warranty extension is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 6520900300 cover?
The manufacturer filed it against 10 model years: 2020 BMW X3, 2019 BMW X3, 2020 BMW X4, 2019 BMW X4, 2020 BMW X5, 2019 BMW X5 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
