What to know before buying: BMW X4

From 4 video reviews and 1 press test · updated 23/09/2026

What the reviews say

• The X4 is a sport-focused crossover: owner feedback on the driving experience is overwhelmingly positive, with communicative steering even around town.[3]one source
• The 2014 xDrive30d test praised its performance, excellent eight-speed automatic and handling, and specifically recommended the adaptive suspension.[1]one source
• The cabin feels premium, with strong fit and finish and well-judged ergonomics; owners also report that the leather wears well.[3]one source
• The coupé roofline compromises luggage usability by reducing vertical space, while the loading lip makes heavy items harder to load.[1][3][5]

Typical faults

• For the generation reviewed by ReDriven, owners report sunroof rattles, opening or closing failures, water ingress and, rarely, cracked glass.[3]one source
• The powered tailgate may fail to open, stop halfway or drop after opening; reports were more common on earlier, pre-update cars.[3]one source
• LED headlights on pre-update cars can develop condensation; some cases require replacement of the complete housing in a labour-intensive repair.[3]one source
• The climate-control blower motor can fail prematurely, while temperature fluctuations may sometimes require extensive HVAC repairs.[3]one source
• In hot climates, the roof-antenna seal may deteriorate prematurely and admit water that can damage the TCB communications module beneath the headlining.[3]one source
• The central locking may intermittently fail to lock or unlock; reported causes include actuators, wiring or the control module.[3]one source

Which engine and version to take

• The M40d uses the 3.0-litre B57 straight-six turbodiesel; the reviewer favours it over the 40i for similar performance, more torque and better economy.[2]one source
• The G02 xDrive30i's 2.0-litre four-cylinder was expected to be the best-selling choice and offers a milder alternative to the M Performance engines.[4]one sourceG02

What to check at the inspection

• Fully open and close the sunroof, listen for rattles, check its drains and look for evidence of water ingress inside.[3]one source
• Cycle the powered tailgate several times; it should open fully, remain raised and close smoothly.[3]one source
• Inspect the LED headlights for condensation, particularly on pre-update cars.[3]one source
• Set a fixed climate-control temperature and confirm it remains stable and that the upper vents provide warm air when selected.[3]one source
• Test both keys because the car can forget a seldom-used key, although it can be paired again.[3]one source
• Use the remote to lock and unlock every door repeatedly so an intermittent central-locking fault is not missed.[3]one source
• Inspect the roof-antenna seal and nearby headlining for moisture because water ingress can damage the TCB module.[3]one source
