i recently bought the prius gen 3 2010 , seller said he changed the engine and also replaced hv battery, I was ok for first two weeks but now when i start in morning, it drive ok and good acceleration, but after 10min drive , it feel sluggish and steering wheel get heavy like manual, it also feel like stuck and then drive just once but then turn very sluggish and feel heavy. I scanned it with TIS but no code found. I checked all wheels but no sticking calipers. It is really really sluggish and heavy steering after first 10min drive. Really worried. Please advice
Just thinking aloud: It's still unusual for 3rd gen to be needing new hybrid batteries. Doubly unusual, to sell vehicles right after replacing the battery. Maybe it was a budget "remanufactured" battery (if it was replaced), and it's started crapping out.
Maybe a clue in this change of behavior after 10 minutes of warm-up? Strange that even the steering would feel heavy??
