This page covers 4 recalls and 18 owner complaints for the 2015 BMW X4.
Complaints for the 2015 BMW X4 are spread thin across 18 total reports, with engine and electrical system each drawing the most attention. On the engine side, owners describe burning smells noticed while driving, in some cases without any warning lights appearing on the dash. The electrical system complaints cover a range of issues without a single dominant symptom tying them together. A pair of airbag complaints rounds out the higher-volume systems, though the details across those reports don't point to a consistent pattern. One report describes a vehicle fire that started at the front of the car while driving, but that appears to be an isolated account rather than a recurring theme across this model year's complaint set.

By System
The 2015 BMW X4 has 4 recalls, the most serious involving the driver's frontal airbag inflator, which can rupture or separate during deployment and send metal fragments into the cabin, posing a risk of serious injury or death.
A separate but related airbag concern applies specifically to xDrive35i-equipped vehicles, where the inflator can explode during a crash, with the same result: sharp metal pieces striking the driver or passengers. Prior repair attempts on some of these vehicles did not fully resolve the issue, which is why multiple campaigns exist for this airbag system.
On the electrical side, a wiring connector in certain X4 xDrive28i vehicles can develop a short circuit, creating a risk of fire. The defect sits in the low-voltage wiring harness and can cause heat buildup without an obvious warning to the driver beforehand.
The fourth recall affects the rear child seat anchor system. The lower anchor bars that LATCH-style child seat straps attach to can be damaged, meaning a child seat may not stay properly secured in a crash. This recall covers a specific range of production dates, and owners of child seat-equipped vehicles should verify whether their vehicle falls within the affected window.
