Inarguably, BMW has carved a niche in the luxury automobiles market. Nonetheless, the brand also has its problems that you should watch out for, especially when buying a used BMW 3 series. For example, the low profile tires and large alloy wheels may produce more road noise because of the significantly firmer ride.
Some Expected Problems with the BMW 3 Series
Seat Belt Mechanism
The seatbelts in high-performance vehicles such as the BMW 3 series are complex devices. They are connected to airbags and other safety features, and this may give rise to other problems.
There is a possibility that the seat belt mechanism on the driver side for BMW 3 series manufactured between 2014 and 2015 is faulty. This makes it a bit difficult to use in cold weather, leaving you stuck for a few minutes at home in the morning. Check if the current unit is affected and have the mechanism replaced if it is.
For vehicles manufactured between 16 May 2018 and 7 June 2018, a fault with the crankshaft sensor could limit its performance. This problem causes the engine to transition into an emergency reduced power mode.
A certified technician should confirm if your vehicle has this problem and recommend a crankshaft sensor replacement.
Sometimes on your way to work, your BMW 3 series engine may decide to stall, mostly due to fuel pump issues. Just before the engine cuts out, you will notice an error message and a warning lamp.
Check with your trusted mechanic or BMW dealer if your car is affected by fuel pump issues and determine if a replacement is necessary.
