BMW i4 reliability & safety rating

BMW has been building reliable electric cars for some time now, and while there’s no Euro NCAP rating for the i4 just yet, it should also be safe in a crash

Overall rating

4.5 out of 5

Reliability & safety rating rating

4.0 out of 5

A final verdict in these areas will have to wait until the i4 is independently crash-tested by Euro NCAP and the car has been in customer hands long enough for long-term reliability data to be gathered, but we can say that initial signs are promising in both areas.

BMW i4 reliability & problems

The i4 only hit UK roads for the first time in late 2021, so long-term reliability data is thin on the ground for the moment. However, BMW’s pioneering electric city car, the i3, has been on sale for nearly a decade without major issues coming to fore, so it’s safe to say the brand knows how to build a reliable electric drivetrain.

In the most recent edition of the Driver Power customer satisfaction survey (which was carried out before the i4 went on sale in the UK), BMW ranked 21st out of 29 brands evaluated, with an overall score of just over 85%.


It’s difficult to make a definitive pronouncement here, as neither the i4 nor the petrol-engined 4 Series Gran Coupe on which it’s based have been through Euro NCAP crash-testing just yet. BMW has a decent track record in this area, however, so a five-star score is to be expected when it does get evaluated.
