Is an Extended Warranty Worth It for a 2018 Mazda CX-3?

Model-year reading

What the 2018 record can and cannot say

Compared with other Mazda CX-3 years here, the 2018 total is 5 below the median year in this model file. Its raw count is 10, with no denominator for vehicles sold.

At 2 reports, Back Over Prevention is the most common displayed tag. The 20% share describes submitted complaints only; it does not describe the fleet.

Engine replacement or major internal repair provides the strongest parts-only stress test at a $7,000 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: 10 submitted complaints, 1 recalls and 475 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: 32 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.
