Should You Buy the 2021 BMW X3?

Reliability standing is good, but this year ranks below average among 2021 SUVs and sits in the middle of the eight scored X3 years. Owners filed 10.4 complaints per 10,000 sold. The 2022 rates better with fewer complaints and recalls, while the 2020 rates about the same. Independent repair-cost data puts yearly repairs above the class norm.

Failure to start leads the complaints. Cars click and refuse to start, or will not restart after auto start-stop shuts the engine off in traffic. Many reports involve a starter-related electrical recall, and owners say dealers have no parts. The most serious pattern is unintended acceleration while parking. Cars surge forward at low speed with the brake pressed, and both crash reports involve a tree or a wall. Owners also wait on parts for the rear cargo rail recall, though none report a rail failing.

Ask the seller for proof that the electrical and cargo rail recalls were completed. The 2022 is worth a look as well.

Compared to the 2022 BMW X3, which scored 3 points higher. See also the 2020 BMW X3 for an earlier comparison.

Used Buying Checklist

Key things to inspect or verify before purchasing a 2021 BMW X3.

Run the VIN for open recalls on the starter and rear cargo rails, and confirm both repairs were completed.
Start the car several times from cold and listen for clicking or a failed first start.
Let auto start-stop shut the engine off in traffic and confirm it restarts promptly every time.
Check that both daytime running lights work and the headlights stay steady in the Auto setting.
Inspect the sunroof glass for cracks and check the headliner and footwells for water stains.
Back up slowly in an open lot and watch for sudden brake lockups from parking distance control.
Drive a straight highway stretch with a light grip and note any drift that needs constant correction.
Scan for stored codes and ask for service records showing repeat check engine light visits.

2021 BMW X3 Common Problems by Component

ELECTRICAL SYSTEM

19 complaints

Failure to start is the main pattern. Cars click and refuse to start, or fail to restart after auto start-stop shuts the engine off in traffic, sometimes leaving the car stuck in park. Many reports concern a starter-related electrical recall. Owners worry about fire, but dealers have no parts for the repair. Other reports describe melted daytime running light modules quoted at $4,200, a failed plug-in hybrid battery cell, module communication faults after a DME software update, and a satellite radio ad covering the speedometer.

19 complaints total

UNKNOWN OR OTHER

19 complaints

Sunroof glass shatters or cracks with a loud bang while driving. Leaking sunroof seals let water drip into the cabin in rain. Several reports are about recall delays. Owners under the starter fire recall are told to park outside, and owners waiting on the cargo rail recall say parts are not available. Single reports describe a dashboard that goes dark at startup, false braking traced to a heat-deformed camera housing, repeated windshield cracks, and an engine left idling in a closed garage.

19 complaints total

STRUCTURE

9 complaints

Most complaints here involve the recall for the interior rear cargo rails, whose attachment bolts can let the rails detach in a crash. Owners report that replacement parts are not available and say the wait has gone past a reasonable time. None of these owners report an actual failure. Separately, sunroof glass shatters while the car is moving, and a power tailgate closes on a person without its sensor stopping it.

9 complaints total

VEHICLE SPEED CONTROL (7 complaints)

VEHICLE SPEED CONTROL

7 complaintsSafety-related

Unintended acceleration while parking is the most serious pattern. Owners describe the car surging forward at low speed with the brake pedal pressed, and both crash reports involve hitting a tree or a wall while pulling into a space. In another report, cruise control set at 75 mph climbs past 90 mph on its own. Other complaints cover emergency braking with no vehicle nearby and an analog speedometer marked in 10 mph steps that makes exact speed hard to read.

7 complaints total2 crashes

EXTERIOR LIGHTING (3 complaints)

EXTERIOR LIGHTING

3 complaints

Screen dimming is the main complaint. The instrument cluster and center display set daytime brightness from a light sensor, and there is no manual daytime adjustment. Window tint, shade, or leaving a garage can make the backup camera, navigation, speed, and warnings hard to read. One report also describes headlights in the Auto setting switching on and off by themselves, which becomes a risk if it happens while driving in the dark.

3 complaints total

ENGINE (3 complaints)

ENGINE

3 complaints

Persistent check engine lights are the most common complaint. Cars go back to dealers 2 or 3 times without a lasting fix, including the plug-in hybrid. Owners say not knowing the cause makes them hesitant to drive. A separate report on the B58 engine describes an oil level reading that will not rise above 20%. The owner links it to a failing oil pump and mentions low oil pressure warnings.

3 complaints total

SERVICE BRAKES (3 complaints)

SERVICE BRAKES

3 complaints

Brakes lock up abruptly when backing up because parking distance control reacts to obstacles that are not there. Another report describes a brake pedal that stiffens while approaching a stop light, causing the driver to run the light, at about 50,500 miles. Owners also report loud screeching and a slipping feel under hard braking that gets worse in wet or snowy weather, and repeat dealer visits do not resolve it.

3 complaints total

STEERING (3 complaints)

STEERING

3 complaints

The car wanders on the highway and needs steering corrections every 5 to 10 seconds to stay in its lane, even after a dealer alignment. Owners say repeated dealer visits do not fix it. One car needed both front tie rods replaced at 28,000 miles after loud popping over uneven pavement. Its bushings were worn, and the owner feared it could lead to a loss of steering control.

3 complaints total
