Common problems with BMW X4

BMW X4 Problems

The BMW X4 is a stylish, powerful, and luxurious compact luxury SUV. But like most cars, this compact SUV also comes with some issues that are worth noting. Nonetheless, what are the common problems with the BMW X4?

Common problems with BMW X4 are malfunctioning airbags, turbo wastegate issues, faulty electrical system, DPF clogs, the engine failing to start, loss of wheel control, and faulty seatbelt lock recognition. These and many other issues make the BMW X4 one of the least reliable BMW models.

What are the common problems with the X4?

Malfunctioning airbags

BMW usually recalls some cars if it detects they have a manufacturing problem. Several 2017 to 2019 BMW X4 models came with faulty airbags. BMW discovered that a screw connection from the passenger’s airbag to the instrument panel may not have been made according to specifications.

Therefore, if the airbag is activated, the panel cover may break into pieces and be thrown against the passenger, increasing the danger of an injury when there is an accident.

Faulty electrical system

Like most BMWs, the BMW X4 also suffers from a faulty electrical system. This can be caused by several things, such as a broken starter, corrosion on battery terminals, immobilizer error, clogged fuel filter, dead 12v battery, blown fuse, or bad alternator. If your car is experiencing electrical issues, ensure to fix the root of the problem.

Turbo wastegate issues

This problem is common in the petrol-engined BMW X4 model. The turbo wastegate becomes noisy, making the check engine light come on and the car will gradually stop. Note that this particular issue is normally brought about by an aging turbocharger. So, if the turbocharger is worn out, you should replace it.

The engine fails to start

The main culprits that cause the engine not to start are electrical issues. We had already highlighted some of the major electrical issues and some of them may affect the engine as well. For instance, corrosion on battery terminals, empty gas tank, bad alternator, and broken starter may prevent the engine from starting.

Ensure to fix the underlying electrical and engine issues if you want it to perform optimally.

The DPF clogs

The DPF or diesel particulate filter clogs when it cannot burn away all the excess diesel particulate matter that they filter from the car’s exhaust. As a result, the car fails to regenerate and the DPF ends up clogging.

If the clog is not excessive, you can try unclogging the DPF by warming up your engine well and driving it at high speed for about 10 to 20 minutes. This should be enough to unclog the DPF. But if the DPF is damaged, you will have to replace it.

Faulty seatbelt lock recognition

Another issue that forced BMW to recall some BMW models is a faulty seatbelt lock recognition. This issue was discovered in some of the 2019 and 2020 BMW X4 models. It was believed that the cable linking the hall sensor with the seat buckle might be extremely short.

As a result, the sensor might detach from the buckle, causing a faulty seatbelt lock recognition, which affects the functioning of the restraint system and deployment of the airbag, thus increasing the danger of injury in case of an accident.

Loss of wheel control

This issue is common in the 2018 and 2019 BMW X4M models. The wheel losses control because of a vibration fatigue failure of the track rod. Besides, the vibration fatigue failure happens because of an exceptional bending load. If this occurs, the wheel will lose control on one side of the car, increasing the danger of an accident.

The good news is that BMW recalled all cars with this defect and fixed them. Hence, if you’re investing in a used 2018 or 2019 BMW X4M, ensure that this problem was fixed before paying for it.
