Summary
The Toyota Prius V has 7 recalls spanning the 2012–2017 model years, with the most serious being a hybrid inverter defect on 2014–2017 models where excessive voltage in the Intelligent Power Module can shut down the hybrid system without warning, stalling the vehicle in traffic and raising the risk of a crash.
A closely related issue affects 2012–2014 models, where a component inside the inverter assembly can overheat and force the vehicle into a reduced-power mode, leaving the driver with only enough propulsion to travel a short distance. On 2012 models specifically, inverter damage under certain driving conditions can cause warning lights to appear and cut drive power to the wheels entirely. Because these inverter issues overlap across the 2012–2017 production span and involve the same core system, owners of any model year should be aware that the hybrid drivetrain has been the subject of repeated attention. On 2014–2015 models, the passenger seat sensor that determines whether to activate the front passenger airbag can be miscalibrated, meaning the airbag may not deploy in a crash when it should. Finally, certain aftermarket replacement tail lights sold for 2012–2013 vehicles have the brake light and tail light circuits reversed, so the brake lights glow continuously at rest and switch off when the pedal is pressed, removing the braking signal that following drivers rely on.
