General Motors has issued two new service bulletins to address a labeling error affecting select units of the 2024-through-2025 Chevy Silverado EV. The issue stems from an incorrectly applied “First Responder Emergency Cut Loop” label, which could pose a serious risk during an emergency by directing first responders to cut the wrong component. GM Authority initially reported on this issue last year.
The new Service Updates are tagged N252503100 and N242451390-03, and both were released on May 6th, 2025. The bulletins state that some Chevy Silverado EV units show incorrect placement of the emergency cut loop label on the 12-volt battery negative cable. This label is intended to indicate where emergency personnel can safely disable the vehicle’s electrical system during a crash or fire. However, the correct location for this label is on the high-voltage service lockout harness, not the low-voltage battery cable.
The mislabeling could lead first responders to cut the wrong cable, potentially leaving the vehicle’s high-voltage system active. The issue may also pose a risk of electric shock, fire, or further injury to both rescuers and vehicle occupants, as well as a potential delay in rescue efforts.
To resolve the issue, authorized EV dealerships have been instructed to inspect units of the Silverado EV affected by the Service Update. If the label is incorrectly placed, technicians will remove it from the 12V battery negative cable and ensure the correct label is affixed to the high-voltage harness. It’s also possible that the label is missing altogether, in which case the technician will need to apply the label to the correct component. The repair is expected to take just 10 minutes to complete.
The labeling fix applies to Silverado EV units currently in dealer inventory, as well as customer-owned vehicles that return to the dealership under warranty.
The issue first came to light in August of 2024 with the release of Service Update N242451390, as GM Authority covered previously. However, the exact number of affected units remains uncertain.

It must be affecting far more than just the Chevy Silverado EV because nearly every pickup truck on the road I see is driving around like there’s an emergency.
They’ve got someone getting paid $40+ an hour who can’t even apply the proper label? Another reason why I’m jumping ship with GM..
You’re kidding yourself if you think these types of issues don’t exist at other automakers when launching new models.
Automakers need to standardize on a “In case of emergency cut everything in this area”.
When it’s in the middle of the night, in the rain, with people critically hurt, the last thing a rescue crew needs is to be finding labels in a mangled vehicle. A standard “chop everything here” location would help everyone.
