2020 BMW Z4 recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-18. Recalls apply to specific VINs — run your VIN to confirm.
6 safety recalls, most serious first
1. Lights
What's wrong, in plain English: Headlights, tail lights or turn signals may not work, making the car hard to see. The headlight control units may fail causing a loss of one or both of the headlights.
What could happen: Headlight failure can reduce the driver's visibility, increasing the risk of a crash.
The fix: BMW will notify owners, and dealers will replace the headlight control units, free of charge. The recall is expected to begin January 17, 2020. Owners may contact BMW customer service at 1-800-525-7417 or Toyota customer service at 1-888-270-9371.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2020 Z4.
- Book a repair at any authorized BMW dealer. Quote NHTSA campaign 19V850000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-525-7417.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

2. Backup camera
What's wrong, in plain English: The rear camera may not show an image when reversing. The back-up camera and display settings can be adjusted such that the rear view image is no longer visible and the system will retain that setting the next time the vehicle is placed in reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rearview Mirrors."
What could happen: The lack of an image in the back-up camera display increases the risk of a crash.
The fix: BMW will notify owners, and dealers will update the back-up camera software, free of charge. The recall began November 8, 2019. Owners may contact BMW customer service at 1-800-525-7417 or Rolls-Royce at 1-877-877-3735. Toyota owners may contact Toyota customer service at 1-888-270-9371.

Engine starter safety recall came out in September 2025, with no remedy or parts existing for fixing it. 5 months later, and no timeframe is provided for a remedy. This is a major fire risk given the amount of rain now that could corrode the starter and lead to a fire.

BMW'S LANE DEPARTURE SYSTEM ACTUALLY PULLS THE CAR'S STEERING LEFT OR RIGHT, AND COULD CAUSE THE CAR TO COLLIDE WITH ANOTHER VEHICLE OR RUN OFF THE ROAD. I EXPERIENCED THIS WHILE DRIVING ON THE FREEWAY IN SOUTHERN CALIFORNIA. THE LANE DEPARTURE SYSTEM ALMOST PULLED MY VEHICLE INTO THE ADJACENT LANE.
