Canada2025–2026 Chevrolet CORVETTE vehicles are affected. A software problem can make the turn signal telltale flash at the same speed as when a rear turn signal bulb fails, so you may not notice a rear bulb is not working, which could increase the risk of a crash. General Motors will notify owners by mail and send a wireless over‑the‑air software update to eligible vehicles, or you can schedule an appointment to have the update performed at a GM dealership.
How to identify it
2025–2026 Chevrolet CORVETTE
The hazard
On certain vehicles, a software problem could cause the turn signal telltale to flash at the same speed as when a rear turn signal bulb fails. As a result, you may not notice when a rear turn signal bulb is not working. Canadian regulations require a change in the turn signal flash rate when a bulb fails.
A turn signal telltale that doesn't work properly could cause you to be unaware when a turn signal bulb fails. Turn signals that don't work may cause a person not to recognize when a driver intends to turn or change lanes. This could increase the risk of a crash.
What to do
General Motors will notify owners by mail and send a wireless over-the-air software update to eligible vehicles to update the exterior lighting control module software. Alternatively, you may schedule an appointment to have the update performed at a GM dealership.
