What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 104 complaints with NHTSA since 2015. 31 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.
I brought a brand new BMW IX fully electric vehicle in May, 2023. A couple of weeks ago in early September, the “Emergency Call System Malfunction” warning light came on, and I can also smell a chemical burn from the vehicle. I dropped it off to Eastbay BMW in Pleasanton, California. 4350 Rosewood Drive, Pleasanton, California 94588.

I was driving on Single Pedal Drive on a freeway with the 2024 BMW IX, there was a slow down ahead of me. I removed my foot from the pedal and waited for car to slow down, but car didn't slow down enough. Then I slammed the brakes hard, but the brake didn't engage. In fact, brakes were pushed back against my foot.
