Can a bad radio cause low battery voltage on 2006 Dodge Durango?

Asked by Jun 23, 2015 at 05:43 PM about the 2006 Dodge Durango Limited 4WD

Question type: Maintenance & Repair

Three months ago, the car would jump while accelerating/decelerating. Eventually the
'Check engine' light came on. Took it in, they said it was bad speed sensors. A month
ago, I had the alternator and battery replaced. Last week, the car started jumping again
and the 'check engine' light came on again. Took it to the same place - they said faulty
speed sensors and replaced them again. The check engine light and jumping problems
started again on Sunday. Took it in this morning, they hooked it up to the scanner and
said a 'low battery voltage' code came up. They are now saying it's the radio, which the
screen went black a few months ago, but the radio still works. Is it possible for the radio
to cause all of this?

I have never seen a radio cause a driveability problem. The battery could be getting discharged by the radio, but if the vehicle still is able to crank and start the alternator would bring the voltage to normal upon start up. Find a new place to take you car for repair. Perhaps take it to a Dodge dealership for repair.
