What's involved
What this repair actually is.
The DC-DC converter does the alternator's job in a hybrid or EV, stepping high-voltage pack power down to run the 12V system. When it fails, the 12V battery drains while you drive and the car can shut down. We confirm the converter is at fault, replace it, and verify charging output across all loads.
Symptoms
How you can tell.
- 12V battery keeps dying even after replacement
- Dash lights flicker or dim while driving
- Accessories cut out on the road
- Multiple warning lights across the dash
- Car shut down or wouldn't restart after driving
If you delay
A failing DC-DC converter will eventually kill the 12V system while driving, shutting the car down without warning.
