Should You Buy the 2021 BMW X6?
Reliability standing is good, yet this model year sits well below average when set against other 2021 SUVs. Within the X6 line it lands in the middle of five scored years. The 2022 model rates better, with fewer owner complaints and fewer recalls, so it is the obvious car to compare against.
Electrical system failures are the problem owners report with a mileage attached, starting around 49,000 to 53,000 miles. Owners filed 7 complaints in total, and one involved a crash. Federal recall records list 7 recalls, covering visibility, back over prevention, hydraulic service brakes, steering, the electrical system, exterior lighting and tires. The brake, steering and tire recalls are the ones to confirm first.
Ask the seller for proof that every recall was completed, plus repair records for any electrical work. Independent repair-cost data puts yearly repairs for the model at $1206, against $1127 for its class. If a 2022 costs only a little more, it is worth a look.
Compared to the 2022 BMW X6, which scored 6 points higher.
