BMW M5 problems

The BMW M5 is a high-performance sedan and one of the most iconic sports sedans on the market. On top of that, it is very comfortable and comes with advanced features. However, like most BMWs, the BMW M5 also has several issues that interested buyers and owners should look out for.

What are the common problems of the BMW M5?

Excessive oil consumption

This is not only a BMW M5 issue as it occurs on almost all BMWs. Most old BMW models have this problem. On top of that, most BMWs also leak oil. BMWs use a lot of oil because of the type of engine they come with. They are usually equipped with powerful, efficient, and low-friction engines that use a lot of oil.

Tailgate window failure

One of the first parts to wear out in a BMW M5 is the tailgate window actuator. When this part is faulty or wears out, you will notice water leaking into the tailgate window release actuator. To correct this problem, you will be required to replace the faulty tailgate window actuator.

Failed electric seat

Another common problem with the BMW M5 is a faulty electric seat. In some cases, users have reported that the electric seat or steering column failed to be adjusted. This can be caused by a software problem or a bad multi-control unit. Upgrade the software and if it fails, replace the multi-control unit.

Defective rear coil springs
