The BMW 3 Series was introduced in 1975 and helped establish small executive cars as having good handling and interior quality. Over time it has improved performance but some issues can still arise. These issues include airbags deploying unintentionally due to a faulty switch, loss of braking from a loose pedal connection, overheating from cooling fan problems, suspension issues from loose ball bearings, fuel injection failures from pump bearing issues, and power steering failures from out-of-spec control modules. The document provides details on these potential problems that owners of BMW 3 Series cars should be aware of.

1. BMW 3 Series

2. The BMW 3 Series
was introduced in
1975 that eventually
created a benchmark
small executive car in
terms handling and
interior quality.

3. Over time, the BMW 3
Series car has evolved
in terms of handling
and performance, but
still there are a few
problems associated
with these cars.

4. Some of the problems
associated with BMW 3
Series cars are
mentioned below.

5. Airbag problem

6. The airbags start to
trigger even if you are
not involved in an
accident.

7. This problem is
mainly due to a
faulty safety
isolation switch.

8. Braking
problem

9. The braking problem
arises due to a loose
connection clip
between the brake
pedal and the brake
servo.

10. When your car is
under extreme strain,
it could result in a
complete loss of
braking.

11. Cooling fan
problem

12. There are various
risks associated with a
problem with the
cooling fan of a BMW
3 Series.

13. Such errors could
cause the electronics
to thermally overload
and get damaged.

14. Suspension
problem

15. The ball bearing in
the front suspension
strut top mounting
may not have been
properly installed.

16. When there is less
weight on the wheel,
the ball bearing could
work loose.

17. Fuel injection
problem

18. If your BMW does not
start, then there might
be issues with the fuel
injection system.

19. The bearings in the
high-pressure fuel
injector pump can fail,
resulting in a stalled
engine.

20. Steering
problem

21. Due to a component
in the control module
not being to
specification, it may
result in failure of the
power steering
assistance.

22. Generally, such a
problem is indicated by
a warning light on the
dashboard.
