2015 Toyota Prius V

Brake-related complaints dominate what owners of the 2015 Prius V report. The most common pattern involves the brake system warning, ABS, and traction control lights illuminating together, often accompanied by noticeably harder brake pedal feel. Several owners describe this happening in wet conditions, with some reporting reduced braking effectiveness when it occurs. A specific hardware failure that comes up across multiple reports is the brake booster pump and accumulator, owners describe these components failing during normal driving. Some owners also note a cycling motor sound from under the hood tied to these warning light events. Vehicle speed control draws a smaller cluster of complaints, and a couple of powertrain reports describe an intermittent loss of drive power at highway speeds alongside a check engine light, sometimes paired with a knocking sound from the engine compartment.
