The short answer

NHTSA received Toyota Motor Engineering & Manufacturing’s report on Oct 4, 2018. Copied from NHTSA on Oct 27, 2026.

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

If the hybrid system shuts down unexpectedly, it can increase the risk of a crash.

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2010-2014 Toyota Prius and 2012-2014 Toyota Prius V vehicles.

Excessive voltage in the Intelligent Power Module (IPM) within the inverter may cause the hybrid system to shut down, causing the vehicle to stall while being driven.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • This recall names only model years before 2015, which have no pages here. Your VIN, at NHTSA, says which recalls are open on a vehicle.
  • How many have been returned or fixed isn’t in the notice.
