" Under Voltage
Consumer Defective!"

I occasionally get this warning, and it comes and goes
Any Idea??

 

Check out the Alternator/voltage regulator, I've seen this message on other forums before, unfortunately I cannot remeber which ones... you may want to "google" Undervoltage Consumer Defective..... undervoltage would seem to be a lack of proper voltage.

 

bad voltage regulator. get it replaced, before it leaves you stranded
