Recalls & safety

Recall history hasn't been loaded for this model year yet.

Whether a recall is still open on a specific car depends on its VIN. Check it free at NHTSA's VIN lookup (nhtsa.gov/recalls), or ask the seller for proof the repair was done.

Pros & cons

Pros

  • Class-leading technology, driver-assist and cabin quality, with a strong 45e plug-in hybrid option.
  • Excellent B58 inline-six, smooth, powerful, efficient and the most reliable engine in any X5.
  • Much-improved reliability and notably lower projected repair costs than older X5 generations.

Cons

  • Still premium to maintain and insure, requires premium fuel, and the V8s are thirsty.
  • 48V electrical and starter glitches plus early software bugs on launch-year cars.
  • 2024 facelift carries a first-year integrated-braking-system recall to verify.
