Is an Extended Warranty Worth It for a 2017 BMW i3?

Model-year reading

What the 2017 record can and cannot say

The 2017 record contains 51 submitted complaints, 37 above the median year in this model file. Report volume is not a failure probability because vehicle age and sales exposure differ.

Steering leads the displayed component tags with 11 reports, accounting for 21.6% of this year's submitted complaints. Use that signal to inspect coverage wording, not to predict the next repair.

EV traction battery replacement has a midpoint parts estimate of $13,000, before local labor. A service contract only changes that exposure when the part and cause of failure both qualify.

Evidence and provenance

Three evidence layers, kept separate

NHTSA signals: 51 submitted complaints, 3 recalls and 201 manufacturer communications. These are report counts, not failure probabilities.

EPA configuration evidence: 3 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.
