Symptoms of a 12V failure
No response from the key or app, frunk and doors that will not open, a black infotainment screen, warning chimes on wake, or a vehicle that will not shift out of park.

EV 12V Battery Assistance
A dead 12V battery leaves an EV unresponsive even when the main pack is nearly full. Doors may not unlock, screens stay dark, and the vehicle will not power up. That is a job we solve fast.
What we do on site
A provider tests the 12V system, jumps or powers the vehicle to bring it back online, and advises whether the battery needs replacement. 12V assistance starts at $99.
Preventing repeat failures
Repeated 12V faults usually mean an aging battery or a parasitic drain. We document what we find so your shop or fleet team can act on it.

FAQ
Common questions.
- Why does an EV have a 12V battery?
- It powers the computers, locks, lights and contactors that wake the high-voltage system. Without it the car will not start.
- Can you replace the 12V battery on site?
- In many cases yes, depending on vehicle and parts availability. Dispatch will confirm when you call.
- Does a full charge fix it?
- No. A charged main pack cannot compensate for a dead 12V battery.
