What's wrong?
The seatbelt-unfastened warning light on the 2020 Trans Tech Roadstar, Sst, and ST Aero buses is part of the instrument cluster. Its job is simple: when the ignition moves to "on" or "start" and a seat belt is not buckled, the light turns on so the driver gets an immediate reminder.
These buses were built on 2019 Chevy Express cutaway chassis affected by a software error. That error delays the seat belt reminder telltale after startup, so the warning light stays off for about five seconds instead of illuminating right away. The hardware is not the issue; the problem is the startup logic that controls the light.
There is no warning sign before failure. What an owner or driver will notice is the delayed reminder: after startup, the seatbelt-unfastened light does not come on immediately when the belt is unbuckled.

What's the safety risk?
Without the seatbelt warning reminder, a driver has less prompt to buckle up, which increases injury risk in a crash. Fasten the seatbelt before every trip and schedule the repair soon. Repair is free at any franchised Trans Tech dealer.
What should I do?
- Check your VIN to confirm your 2020 Trans Tech Roadstar, Sst, or ST Aero bus is included in this recall.
- Contact the GM dealer named by Trans Tech to schedule the free instrument-panel-cluster reprogramming that restores the seatbelt warning light.
- Bring the recall notice if Trans Tech mailed one. If not, reference recall number 20V196 when you call.
- Buckle the driver seatbelt before moving the bus; the warning light is unreliable until the software update is complete.
- Call Trans Tech customer service at 1-845-988-2333 with questions about scheduling or owner notice details.
What happens at the repair
At a GM dealer, the instrument panel cluster is reprogrammed so the seatbelt warning light works as required when the ignition is moved to the on or start position. The software update is free under the recall, and parts and labor are covered. If you paid out of pocket for this instrument cluster repair before the recall, GM's reimbursement plan covers eligible repairs under the plan it submitted for this campaign. Ask the dealer or Trans Tech customer service what documents GM needs for the claim.
