Model-year reading

What the 2021 record can and cannot say

Compared with other BMW i3 years here, the 2021 total is 14 below the median year in this model file. Its raw count is 0, with no denominator for vehicles sold.

No component has enough displayed reports to provide a useful lead signal for this year.

EV traction battery replacement provides the strongest parts-only stress test at a $13,000 midpoint. Local labor raises the bill, while claim rules can lower what the plan actually pays.

Evidence and provenance

Three evidence layers, kept separate

NHTSA signals: 0 submitted complaints, 0 recalls and 21 manufacturer communications. These are report counts, not failure probabilities.

EPA configuration evidence: 2 matched fuel-economy configurations help remove incompatible repair scenarios.

Repair-cost modelling: 37 applicable non-wear scenarios use published benchmarks where available plus parts and independent-shop labour assumptions. These ranges are not dealer quotes, repair-shop quotes or invoices.
