Model-level reading

What changes the warranty calculation

158 submitted complaints appear in the BMW i3 file. They stretch across 7 model years, with the middle annual count at 14.

Report volume peaks at 51 for 2017. Without registration counts or equal vehicle age, the peak cannot serve as a defect ranking.

Among the matching repair categories, EV traction battery replacement tops the parts midpoints at $13,000. That is the system I would locate in both the factory warranty and any proposed service contract.
