When you are looking at getting a new car, regardless of whether you are leasing or buying, it’s always good to know what sort of problems you may encounter with the model.

No car is without fault. Some are more dependable than others, that much is true, but there can be problems with every model, regardless of how reliable or unreliable it is. And in recent years, it appears that our cars have actually become less reliable.

So, it’s always good to know the common problems you may have to overcome for the duration of your ownership.

In this article, we are going to look at some common BMW problems, looking at the brand as a whole and individual models.

Common problems with the BMW 1 Series

The BMW 1 Series is a perfect car for small or new families. But what sort of problems might you encounter?

  • Gearbox leaking
    • This is seen on the automatic gearbox and is the gearbox plug sleeve seal failing.

What are the common problems with the BMW X6?

The BMW X6 is larger than the X5, and is perfect for larger families. However, it’s still important that you know what problems you may encounter.

ReliabilityIndex report that the electrics account for 43.48% of the problems, with the axle and suspension accounting for 26.09%. There have been no problems reported for the transmission, braking system or the steering system, which is positive.

The following are some other problems you may encounter;

  • Problems with the engine
    • This is seen on the diesel engines and it’s due to the swirl flap braking. This can let metal debris into the engine and can lead to something much more serious.
  • Handbrake problems
    • This is the same as the X5 and is due to it needing a software update

  • Door rattles
    • If your door is rattling then this could be down to the poor fitment of the door cards. To fix this they will have to be adjusted slightly.
  • Adjustment of the front seats or steering column
    • If you are struggling to adjust the electric front seats or steering column then this is a problem with the switch assembly. They both run on the same switch assembly which is why it can affect both.

And finally, what are the problems that are most widely seen across all BMW models?

  • Door locks
  • Rattling
    • We have mentioned this a few times above and is often heard coming from the doors
  • Electrical problems
    • Electrics have accounted for many problems on ReliabilityIndex. The problems vary from model to model, but they are quite common with BMW’s
  • Check engine light
    • Again, the engine has also accounted for a lot of problems with the BMW. This can be anything from something minor to something a lot bigger.

Those are some of the problems that you might see in all BMW models. Of course, you might not see any problems at all, but it’s always good to be informed of the issues you may encounter. This allows you to compare with other models you may be considering.
