HYUNDAI service brakes recall — 21V840000

What does this record mean?

Hyundai Motor America reported recall 21V840000 to NHTSA on October 27, 2021. The record falls under service brakes and covers 1 make-model-year combinations across HYUNDAI, model years 2021–2021.

A recall is the manufacturer identifying a safety-related defect or a non-compliance with a standard in a group of vehicles, and reporting it officially. It does not mean the whole vehicle is faulty: it covers a specific condition found in a specific part, within a specific build range.

This record concerns a brake system defect. Brake recalls can cover longer stopping distances, a change in pedal feel, or a leak in the hydraulic circuit. Whether the defect is present in your specific vehicle depends on its build date and production batch.

What should I do?

If you notice anything unusual in braking — the pedal going deeper than normal, a spongy feel, a brake warning on the dashboard — stop driving the vehicle and contact the dealer. The recall work is free of charge even if you have seen no symptom, so there is no reason to postpone it.

Work carried out under a recall is done at no cost to the owner. This does not depend on the vehicle still being in warranty: a recall is not a warranty claim, it is a separate obligation. The dealer should not charge you for labour or parts.

Whether a record covers your vehicle is determined by make, model and model year — but not every vehicle of that model year is necessarily included. The manufacturer usually covers a specific build date range. Only a VIN-based lookup gives a definite answer.

Where is the VIN?

The VIN has 17 characters and appears in four places: on a plate at the lower left corner of the windscreen, on the label inside the driver's door jamb, on the registration document, and on most vehicles on a label in the engine bay. VINs never use the letters I, O or Q; the similar-looking characters are the digits 1, 0 and 9.

Before you go to the dealer

The work is done at the manufacturer's authorised dealer. Quoting the campaign number when you book shortens the process, because the dealer can order the part in advance. If you are not sure whether your vehicle is covered, verify it on the manufacturer's own VIN lookup page; that link is provided on this page.

Before you go to the dealer, have three things ready: the VIN, the registration document and the campaign number. If you have seen a symptom related to the defect, note when and under what conditions; that speeds up diagnosis. Keep the paperwork showing the work that was done: it is useful when you sell the vehicle or if a second record appears.

The official text on this page is reproduced exactly as NHTSA published it. It has not been summarised, rewritten or interpreted. The rest of the page is written in this language.

NHTSA records cover vehicles sold in the US market. A model with the same name sold in Europe or elsewhere may have been built with different equipment and different suppliers, so whether a record covers your vehicle is settled only by the manufacturer's own lookup.

When a record stops appearing in the source, this page is taken down the same day and the address returns a 410 response; no text is left behind. If you have an objection about a record, you can send it from the correction page.
