How it crashes

NHTSA’s own crash tests, separate from the reliability score above.

NHTSA hasn’t published a crash-test rating for this model year. That’s common for lower-volume or older models. It doesn’t mean the car is unsafe, just that this program hasn’t tested it.

Source: nhtsa.gov/ratings. Star ratings compare vehicles within the same class and size, not across every car on the road.

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.

The fine print: this verdict is computed from public NHTSA complaint and recall records for the 2018 BMW M5 as a model, not for any individual car. A well-maintained example of an “Avoid” can outlast a neglected “Buy”. Informational only, so always get a professional pre-purchase inspection.
