BMW X4 (F26) Problems by Year
The F26 X4 is a coupe version of the F25 X3, offering a swooping roofline and a slightly sportier suspension setup. Positioned as a stylish, less practical alternative to the X3, it targets buyers who want the commanding driving position of an SUV but the aesthetics of a coupe. It shares all the mechanicals, interior parts, and issues of the F25 X3, meaning diesel timing chains, transfer case wear, and firm rides are common. It suits image-conscious buyers who rarely need to carry tall passengers or bulky items in the boot.

- ✓Carefully check the xDrive transfer case for juddering or binding on tight, low-speed turns, often caused by mismatched tyres.
- ✓On the N47 20d diesel (early models), listen for timing chain rattle from the back of the engine on cold startup.
- ✓Test the rear visibility; the sloping roofline makes the rear window tiny, so ensure the reversing camera and parking sensors work perfectly.
- ✓Inspect the frameless-style windows to ensure they seal correctly against the roofline; wind noise is a common complaint.
- ✓Check the steering column for the infamous 'clunk' when wiggling the wheel, a widespread issue on this platform.
- ✓Verify the DPF isn't clogged on diesel models used purely for urban driving; look for warning lights or sluggish performance.
