Reliability, what owners report, and what it costs to keep.
AVOIR's read: running costs are the problem rather than the car itself.
Owners have filed 151 complaints with NHTSA about the 2015 BMW X5 xDrive35d, and it carries no recalls. These are owner allegations rather than confirmed defects, but the pattern of what people complain about is the most useful signal a used buyer has.

Percentile ranks against other SUVs in the catalog.
What stands behind each score for this car:
Owners have filed 151 complaints with NHTSA for this model-year, and engine is the most reported area with 29 of them (19%). No recalls are on record for it.
AVOIR scores its reliability 70/100 (good) from NHTSA recall campaigns and complaint density. That figure is a raw complaint count, not yet adjusted for sales volume, so a high-volume model scores worse than it deserves.
AVOIR scores its longevity 69/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2015 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: skip unless cheap, because running costs are the problem rather than the car itself. Its overall ownership score is 62/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
