Hyundai Tucson Instrument Panel Recall: NHTSA 26V400 Covers 96,310 Vehicles

Status, July 1 source check: source-cleared for a BadPD public-safety recall ledger. The official campaign is NHTSA 26V400 / Hyundai recall 304. Hyundai says 96,310 certain 2025-2026 Tucson, Tucson Hybrid, and Tucson Plug-In Hybrid vehicles may have an instrument panel display that intermittently reboots and temporarily goes blank during vehicle operation.

This is recall-record accountability reporting, not vehicle repair, driving, resale, warranty, reimbursement, legal, insurance, software-update, Bluelink, or purchase advice. The official NHTSA, Hyundai, VIN, dealer, OTA, repair-order, and recall-completion records control whether a specific vehicle is included, updated, reimbursable, closed, or still open.

What NHTSA And Hyundai Records Confirm

Hyundai’s Part 573 report frames this as a noncompliance with Federal Motor Vehicle Safety Standard 101, “Controls and Displays.” The instrument panel display may intermittently reboot while the vehicle is being operated. During the reset, the screen can temporarily go blank.

The safety problem is not cosmetic. Hyundai says an inoperative instrument-panel cluster image could mask essential gauges, including the speedometer and fuel gauge, and could also hide certain on-screen notifications. NHTSA’s acknowledgment letter describes the same public risk as failure to show critical safety information, such as the speedometer or warning lights, increasing crash risk.

The affected population is split across three rows. The Part 573 lists 2,819 2025-2026 Tucson Plug-In Hybrid vehicles built from July 9, 2024 through April 14, 2026. It lists 53,886 2025-2026 Tucson Hybrid vehicles built from June 18, 2024 through May 7, 2026. It lists 39,605 2025-2026 gasoline Tucson vehicles built from June 7, 2024 through April 30, 2026.

Hyundai estimates that 1% of the population has the defect. The component supplier is listed as MOBIS in the Republic of Korea. The involved components are instrument-cluster assembly units, including part numbers 940C3-CW070, 940C3-HD000, 940C3-HD070, 940C3-N9000, 940C3-N9700, 940C3-P0770, and 940C3-CW000.

Cause And Investigation Timeline

The reported cause is a communication error between the instrument-panel cluster assembly and the Head-Up Display, rooted in the instrument-cluster software. Hyundai’s source wording matters because it does not describe a cracked screen, loose dashboard trim, or driver preference problem. It describes software behavior that can reset the cluster and temporarily remove required information.

The chronology begins with Hyundai’s North America Safety Office, or NASO, investigating a customer report from July through September 2025. The report involved a Tucson Hybrid with an intermittent inoperative instrument-cluster condition where the display temporarily went blank during operation. Field data and returned parts were collected and reviewed, and multiple field-claim components were sent to the supplier for bench evaluation.

The supplier was initially unable to duplicate the alleged field condition. From October 2025 through May 2026, Hyundai, the supplier, and Hyundai Motor Company continued joint investigation activities through bench testing and vehicle-level validation. The investigation identified intermittent connection issues associated with the HUD external harness that could cause communication loss between the HUD and cluster assembly.

Hyundai says the problem could reset both the HUD and the instrument cluster, producing temporary loss of required telltales and gauges. Validation included multi-vehicle testing under varying environmental scenarios. Testing confirmed that existing software behavior caused simultaneous reset of both systems during a HUD fault. On June 16, 2026, NASO convened its North America Safety Decision Authority and determined that the condition may produce a temporary loss of the cluster display and indicators, resulting in FMVSS/CMVSS 101 noncompliance.

The incident status is clean but still should be dated. Hyundai’s Part 573 states that there are no confirmed crashes, fires, or injuries/fatalities attributable to this condition in the United States. BadPD is preserving that source status as of the June 23, 2026 Part 573 report, while still treating the recall as a public-safety record because the federal file says required gauges and warnings can be temporarily hidden.

Remedy And Timing

The remedy is software. Hyundai says owners will be told to bring affected vehicles to a Hyundai dealer, where technicians will update the instrument-panel cluster software. Hyundai also says it will provide over-the-air software updates, when available, for eligible vehicles whose owners have opted in to receive those updates through Hyundai Bluelink.

The remedy will be offered at no cost to owners, regardless of whether the vehicle is still covered under Hyundai’s new-vehicle limited warranty. Hyundai also says it will provide reimbursement for out-of-pocket expenses incurred to obtain a remedy for the recall condition according to its reimbursement plan submitted to NHTSA on March 2, 2026.

The production correction is dated. Hyundai says revised software was adopted as a production running change on April 28, 2026. VINs became searchable on NHTSA.gov on June 25, 2026. Dealers and owners are scheduled for notification on August 22, 2026, and the acknowledgment letter says owner notification letters are expected to be mailed that day.

That timing creates an obvious watch item. As of this July 1 source check, the federal file shows the recall and VIN lookup, but the owner-letter and dealer-procedure window is still in the future. A vehicle may be source-listed before the owner has received the mailed notice. A complete later record should include owner letters, dealer bulletin, software update instructions, OTA eligibility details, and completion reporting.

Why A Blank Cluster Is A Public-Safety Record

A dashboard display failure can be easy to understate because the car may still move. The public-safety issue is that required information can disappear during operation. Speed, warning lights, fuel status, hybrid or plug-in hybrid notifications, and safety-related telltales are not decorative. They are how drivers know what the vehicle is doing and whether a condition requires immediate attention.

The hybrid and plug-in hybrid rows add a recordkeeping issue. These vehicles can have additional powertrain-state and charge-related displays that owners may rely on. The Part 573 does not say every blank-screen event disables every system, and BadPD is not adding claims beyond the source file. The source-supported point is narrower: the cluster image can temporarily go blank, and that can mask required gauges and notifications.

For owners, fleets, and resale desks, the useful record chain is concrete: VIN lookup, Hyundai recall 304 / NHTSA 26V400 status, whether the dealer or OTA software update was completed, whether the vehicle was eligible for Bluelink OTA delivery, and whether the campaign is closed. A generic note that the vehicle has “current software” is weaker than a recall-specific closeout record.

For used-car and fleet transactions, this recall also belongs in disclosure files because the owner-letter date falls after the VIN search date. A vehicle can be listed, sold, reassigned, or transferred between June 25 and August 22 before mailed notice arrives. The public record should travel with the VIN, not with a vague memory of whether a letter was received.

Plain-Language File Check

The recall is about the driver’s display. The vehicle may keep moving. The display may go blank for a short time. That can still matter. A driver needs speed, warnings, fuel information, and other required signals while driving.

The source file does not say every affected vehicle will fail. It says Hyundai estimates that one percent of the recalled population has the defect. It also says the condition can hide required information. That is enough for a federal recall and enough for a public record.

The clean owner question is simple: is this VIN listed under Hyundai recall 304 or NHTSA 26V400? If yes, the next question is whether the instrument-panel cluster software has been updated. If the update was delivered over the air, the record should show that the update was installed. If the update was done by a dealer, the repair order should name the recall.

OTA status should be handled carefully. The Part 573 says Hyundai will provide over-the-air updates when available for eligible vehicles whose owners opted in through Bluelink. That does not prove every recalled vehicle is OTA eligible. It also does not prove an update installed on a specific vehicle. A dealer or Hyundai record is still the stronger proof.

The date gap matters. VINs became searchable on June 25, 2026. Owner letters are expected on August 22, 2026. During that gap, a vehicle can be sold or transferred before a mailed notice reaches the owner. A buyer, fleet desk, lender, insurer, or dealer should use the VIN record instead of waiting for a letter.

The incident status should also stay exact. Hyundai says there are no confirmed U.S. crashes, fires, injuries, or fatalities attributable to this condition. That is the current source status. If later records change it, the article should be updated with the new record date and source link.

The final completion record is not available yet in this source set. A complete later file should show owner notice, dealer instructions, OTA instructions, and quarterly completion data. The useful completion data is not only a total number. It should show how many vehicles were fixed, how many could not be reached, and how many were removed from the population.

BadPD Bottom Line

NHTSA 26V400 belongs in the BadPD public-safety accountability lane because it involves a temporary loss of required driver information, a federal controls-and-displays noncompliance, a 96,310-vehicle population, and a remedy window that is not complete yet. The records to watch are owner letters, dealer instructions, OTA deployment, completion reports, and any later record that changes Hyundai’s current no confirmed U.S. crash, fire, injury, or fatality status.

BadPD will update this ledger if NHTSA or Hyundai posts owner letters, dealer bulletins, technical instructions, quarterly completion reports, amended Part 573 records, warranty records, field reports, claim records, court records, repair-order evidence, or incident updates tied to Hyundai recall 304 / NHTSA 26V400.
