2021 Hyundai Sonata

A component is listed below if NHTSA records a vehicle recall campaign, a manufacturer warranty extension or service campaign, or at least 10 distinct consumer complaints.

Recall campaigns

NHTSA lists these campaigns as covering certain 2021 Hyundai Sonata vehicles. One campaign can list several components, so adding these counts is not a way to total the campaigns — 4 vehicle campaigns are on record for this model-year.

  • Fuel/Propulsion System2 campaigns34 distinct complaints
  • Power Train1 campaign24 distinct complaints
  • Visibility1 campaign12 distinct complaints

Manufacturer campaigns

The manufacturer filed these with NHTSA as warranty extensions or service campaigns.

  • Electrical SystemService campaignmost recently May 8, 2025

    A service campaign does not establish that this vehicle is included, or that any work is outstanding. Whether it applies depends on the program and the VIN — confirm with a franchised dealer.

Federal law requires the manufacturer to remedy a safety recall at no cost to the owner — by repair, replacement or refund — for vehicles not more than 15 years old on the date the defect was determined.

Parts are sometimes on back-order and some remedies are interim, so a dealer may not be able to complete the work immediately. A specific vehicle’s current recall status is available through NHTSA’s VIN recall lookup.

OAV lists only communications filed as warranty extensions or service campaigns. Hyundai filed 80 other service communications for this model year; those are not listed.

These federal records are not an input to OAV’s price verdict.

These records describe the 2021 model-year, not any individual vehicle, and are not an inspection. One complaint can be recorded against more than one component, so counts do not sum to the model-year total. Service records for any component listed here are worth requesting from the seller.

Complaints are unverified consumer reports submitted to NHTSA. Mileage is self-reported and frequently rounded. Complaint records as of 2026-09-28. Recall records as of 2026-09-28. Manufacturer communications as of 2026-09-28.
