What owners say
X3
Overall
Sentiment is sharply divided and heavily dependent on model year, powertrain, and ownership phase. For newer models (approximately 2018-2024), owner feedback is generally positive, praising the X3 as a well-rounded, sporty luxury SUV with excellent driving dynamics, comfortable seats, good fuel economy for its class (low 30s MPG for the turbo 4-cylinder), and a high-quality, quiet interior. The B58 inline-six engine (in M40i models) is frequently highlighted as a standout for its power and reliability.

The X3 M40i with the B58 turbocharged inline-six engine is the most recommended version for those seeking performance and reliability. For the four-cylinder models, the xDrive30i (all-wheel drive) is preferred over the sDrive (rear-wheel drive) for its all-weather capability and resale value.

- ⚠Sunroof leaks: Reported in multiple model years, with water ingress noted through the hands-free microphone above the driver's seat. Frequency: recurrent.
XT4
Overall
Mixed sentiment with a clear generational divide. Feedback on the 2019-2023 models is notably more negative, centering on significant powertrain reliability concerns, particularly with the 9-speed automatic transmission, and various electrical/infotainment gremlins. The driving experience for these earlier models is often described as uncompetitive, with an underpowered and unrefined 2.0L turbocharged engine.
Best version to buy
For the 2024-2025 refresh, the Sport trim is frequently mentioned as the desirable configuration, offering a more complete feature set. The Premium Luxury trim is also noted for its value.
Known issues
- ⚠**Transmission failures (9-speed automatic)**: Complete failures, torque converter issues, valve body problems, harsh shifting, and slipping, primarily reported on 2019-2023 models. One owner cited a $13,000 repair quote.
- ⚠**Infotainment/Apple CarPlay connectivity problems**: Intermittent failures to connect, system reboots randomly while driving, unresponsive screens. Issues persist even after dealer replacement of components in some 2019 models.
- ⚠**Underpowered and unrefined 2.0L turbo engine**: Engine runs out of breath at higher RPMs, sounds unpleasant, lacks passing power, and is described as "abysmal" compared to GM's larger naturally aspirated engines. Frequency: recurrent.
