A final verdict on reliability will have to wait until the i4 has been in customer hands for sufficient time to allow long-term data to be gathered, but we do have a definitive appraisal of the car's safety credentials in the form of a four-star Euro NCAP score awarded in mid-2022.

BMW i4 reliability & problems

The i4 hit UK roads 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, was on sale for nearly a decade without major issues to speak of, so it’s safe to say the brand knows how to build a reliable electric drivetrain.

In the 2022 edition of the Driver Power customer satisfaction survey, BMW ranked 19th out of 29 brands evaluated, just ahead of key competitors Audi (22nd) and Mercedes (23rd). Meanwhile, the highest rated individual car was the 3 Series which finished 32nd on the list of 75 best new cars to own.


The i4 was evaluated by independent crash-testing experts at Euro NCAP in early 2022 and in July of that year the organisation awarded the car four out of a possible five stars for safety. Individual segment scores were 87% for both adult and child occupant protection, but a somewhat below-par 64% rating for the BMW's safety assistance technology was the main reason it lost a star on the overall rating. In comparison, the Hyundai Ioniq 6 scored 90% in the same category, while the Tesla Model 3 got 94%.
