What's wrong?
The instrument cluster in a 2025-2026 Tern RC8 is the driver display that shows key vehicle information, including air brake pressure. On an air brake vehicle, the pressure sensors read the primary and secondary air systems and send that information to the display so the driver can see whether the brakes have enough stored air pressure.
On affected Hexagon Purus vehicles, the sensor readings are translated incorrectly before they appear on the digital display cluster. That software scaling error makes the pressure gauge show the wrong air pressure and can falsely indicate a brake system failure. The interim decal overlay changes the gauge markings, and the later software update corrects how the primary and secondary pressure readings are scaled on the display.
There is no warning sign before failure. The issue is in the display information, so the driver sees the incorrect pressure reading or false brake system failure message when the cluster shows it.
Who's affected?
The scope covers the same instrument panel decal issue in the 2025 and 2026 model years.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific truck.
What's the safety risk?
A display that shows inaccurate information can fail to alert the driver to an actual brake issue, increasing crash risk. If your VIN is included, keep the driver display in mind and arrange the software update as soon as it opens. Repair will be free at any franchised Hexagon Purus dealer once available.
What should I do?
- Check your VIN to confirm your 2025-2026 Hexagon Purus Tern RC8 is included in this recall.
- Watch for Hexagon Purus owner notification letters expected to be mailed May 31, 2026, because the software remedy is still under development.
- Contact Hexagon Purus customer service at 1-949-359-8168 with questions and reference recall number 26V253.
- Ask Hexagon Purus how to handle a brake display warning or incorrect air pressure reading until the software update opens.
- Schedule the free software update once Hexagon Purus says the remedy is available; the update fixes the display-cluster error that can show incorrect air brake pressure.
What happens at the repair
Hexagon Purus is still developing the software update, so the final dealer repair is not open yet. Once available, a Hexagon Purus technician will update the software that links the digital display cluster with the air brake pressure sensors. The recall repair is free once it opens. Out of pocket repairs already paid are handled through the manufacturer's limited warranty, not through a separate reimbursement program. Because any condition before the owner notice would have been addressed under that warranty, no separate reimbursement claim is available for this campaign.
