2021 Toyota Corolla: True Cost, Problems & Verdict
185 NHTSA owner complaints · 1 recalls · data-computed verdict. No opinions — public data only.
Editor's note
The Corolla's record is as flat as its reputation suggests, with two dips. The 2009–2011 cars carry the same oil-consumption and steering complaints as the Camry of the period. Read the full note on the model page. 2021 specifically: a year the record favours — 185 complaints, score 70/100. The caveats in the note apply to other years of this nameplate more than to this one.
