Seat Swap

if they do fit mechanically, there are the airbag and seat heater harnesses to worry about, and how will you power them?

 

You may also want to consider the issue of whether a seat swap will allow Toyota to walk away from any liability in the case of an injury accident.

 

Take a tape measure to a Toyota dealer and do some measuring. If the 2015-up seats will bolt in, it shouldn't be an overwhelming task to run wires to power them although it will take some inventiveness. It would be a different story if the 2015-up seats had a memory feature that requires one or more ECU's.

Using a tape measure was how I determined that Scion IQ signal mirror covers would fit our Prius v. I parked our Prius by an IQ at a Tpupta dealership and measured the mirrors on both cars. You should be able to do the same with the seats.

The front seats in our 2012 Prius v Five are my number 1 gripe. I can't begin to get comfortable in the manual 6-way adjustable driver seat of our 2012 Prius v but I can adjust the 8-way adjustable power driver seat in the 2015-up Prius v to fit me reasonably well. The 4-way adjustable power front passenger seat in the 2015-up Prius v is just as bad as the 4-way manually adjustable front passenger seat in our 2012.

Frankly, if you like your 2012 Prius v that much, I think you should consider exchanging it for a 2015-2017 that already has power front seats and improved crash worthiness and step up to a "Five" that has the improved version of the LED headlights and the Advanced Technology Package with PCS, DRCC and Auto High Beam.
