Sonata Limited 2.4L Dohc

This was causing my power to drain from my battery and thus had trouble starting the car. Plus there was no way to shut it off.

Sonata SE 2.4L

  • Automatic transmission

The dome light came on independently and I've not been able to get them to function correctly ever since.
