Odd Electrical Fluctuations 

Weird electrical fluctuations can occur depending on what else your hybrid battery powers. This can range from model to model of Prius,’ and you should seek professional help if you notice electrical fluctuations that aren’t normal. 

Quick Battery Depletion 

If your battery’s charge is depleting very quickly, it could be getting on and needing replacement or to be repaired. Be sure to take your car to a mechanic if you are worried about battery depletion. If the car is still under warranty, get in touch with Toyota too, as there could be a battery fault that needs to be looked at. 

Battery Not Kicking In

If you notice that your battery doesn’t kick in when it used to, it could be starting to fail or die. In these cases, take your car to a mechanic for an inspection where they can check the battery for any faults and make the necessary repairs. 

Clunky Driving Conditions 

As the hybrid battery can sometimes drive the wheels, a bad or dying battery can impact your driving conditions. It might feel clunky or similar to bad transmission.

Be sure to take your car to be checked if you notice any issues too. Addressing and rectifying them straight away avoids them becoming bigger complications down the line.
