FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY

Manufacturer
BMW of North America, LLC
What Happened
The fuel tank in your vehicle is made of two halves that are welded together. In some 2020-2021 Z4 and Toyota Supra models, the weld between these halves might not be strong enough, which could cause it to fail.
Risk if Unfixed
If the weld fails, fuel could leak out of the tank, and if there's an ignition source nearby, it could catch fire.
Free Fix
Your dealer will replace the fuel tank with a new one that's designed to be safer, and it will be done at no cost to you.

EXTERIOR LIGHTING:HEADLIGHTS

Manufacturer
BMW of North America, LLC
What Happened
The headlight adjuster on your Z4 or Supra is supposed to keep your headlights aligned properly. However, in some 2019-2020 models, this adjuster can be turned too far, making it difficult to adjust the headlight beams correctly.
Risk if Unfixed
If the headlight beams are misaligned, you might blind oncoming drivers or have reduced visibility while driving, increasing the risk of a crash.
Free Fix
Your dealer will check and adjust your headlight adjuster plugs to ensure proper headlight alignment, at no cost to you. You should schedule the repair as soon as you receive the recall notice.

BMW of North America, LLC (BMW) is recalling certain 2019-2020 Z4 sDrive30i, Z4 M40i and 2020 Toyota Supra vehicles. The headlamps are able to be adjusted horizontally. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices and Associated Equipment."

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

Manufacturer
BMW of North America, LLC
What Happened
The back-up camera system in your vehicle helps you see what's behind you when you're in reverse. In some models, a software glitch can cause the camera display to lose its settings, so the image goes away when you put the car in reverse.
Risk if Unfixed
Without the back-up camera image, you could be more likely to not see something behind your vehicle, which could lead to a crash when you're backing up.
Free Fix
Your dealer will update the back-up camera software to fix the issue, and it's completely free. You should contact your dealer to schedule the update as soon as possible.
