Deaths

A complaint is an unverified account by the person who filed it, not a finding of fault. One complaint is one ODI number, which is how NHTSA counts them.

A recall is the manufacturer conceding a defect, and the repair is free. Whether one covers your particular car is a question only its VIN can answer, because a campaign covers a production range rather than a model year.

Crash test ratings

NHTSA New Car Assessment Program

NHTSA crashes a car into a barrier and a pole and measures what happens to the dummies inside. This is what it awarded the 2026 Kia K4, and it is a separate question from what owners report going wrong later.

The defect
Kia America, Inc (Kia) is recalling certain 2027 Kia Telluride and 2026 Kia K4 vehicles. The rear center seat belt anchor buckle in the 2026 K4 and the third-row center seat belt anchor buckle in the 2027 Telluride may not latch properly.
The risk
A seat belt buckle that is not latched properly can fail to restrain an occupant in a crash, increasing the risk of injury.
The remedy
Dealers will inspect and replace the anchor buckle assembly, as necessary, free of charge. Owner notification letters were mailed May 5, 2026. Owners may contact Kia at 1-800-333-4542. Kia's number for this recall is SC364. Vehicle Identification Numbers (VINs) involved in this recall will become searchable on NHTSA.gov beginning March 20, 2026.

If this is your car and a dealer keeps failing to fix it, your state's lemon law may require the manufacturer to replace it or buy it back. How many repair attempts it takes, and how long you have to file, is set by the state you bought in and by nothing on this page.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
