Bmw X4 Years to Avoid

The 2015 first-year X4 leads complaints with timing chain issues in the N20 four-cylinder engine, coolant leaks, and various electronic glitches. The N20 timing chain problem is serious and can cause engine failure if not addressed.

Best Bmw X4 Years

The 2021 and newer X4 models use the B48 and B58 engines, which have proven more reliable than the N20/N55 predecessors. The second-generation X4 (2019+) is generally more refined and dependable than the first generation.

Frequently Asked Questions

Is the X4 timing chain issue serious?

Yes. The N20 engine in 2015-2016 X4 xDrive28i models has timing chain guides that can fail, causing catastrophic engine damage. Listen for chain noise on startup. Preventive replacement costs $2,500-$4,000.

X4 versus X3?

The X4 offers identical mechanicals with a sportier roofline that reduces rear headroom and cargo space. The X3 is more practical. Choose the X4 only if the styling justifies the compromises.

Is the X4 M40i reliable?

The X4 M40i uses BMW's B58 turbocharged inline-6, which has proven reliable with proper maintenance. It's more dependable than the four-cylinder N20 engine. Expect typical BMW maintenance costs.

What's the X4 maintenance cost?

Budget $1,500-$2,500 annually for oil changes, inspections, and brake service. BMW maintenance can be performed by independent shops after warranty. The all-wheel-drive system adds no significant maintenance burden.

Should I buy an X4?

Buy the X4 if its styling appeals more than the X3's practicality. Avoid 2015-2016 models with the N20 engine. The second-generation X4 with B48 or B58 engines offers the best balance of style and reliability.
