Summary Verdict
The 2014 BMW i3, as an early electric vehicle, demonstrates good overall reliability, particularly in its core electric powertrain. The primary concerns tend to revolve around the longevity and performance of the high-voltage battery pack, which can be a significant expense if replacement is needed outside of warranty. The optional gasoline range extender, while a useful feature for some, has shown a few minor issues like engine mount wear and oil leaks. Electrical components, specifically the 12V auxiliary battery and charging system, can also present occasional problems. Interior electronics, such as the infotainment system, may experience software-related glitches. Despite these points, the i3 is generally considered a dependable vehicle for its intended urban use, with most issues being manageable or related to the inherent complexities of early EV technology.
