NHTSA 5-Star Safety Rating
The 2018 Toyota Prius C has 3 recalls, the most serious being a DC-DC converter fault that can cut power to the auxiliary battery and cause the vehicle to lose drive while in motion, raising the risk of a crash.
The two recalls covering this issue describe the same underlying problem: an electrical fault disrupts charging to the auxiliary battery, and if the vehicle keeps running in that condition, it can lose power to the drive wheels entirely. Warning lights, dashboard messages, and audible chimes typically appear before the situation becomes critical. The third recall applies only to vehicles sold in Puerto Rico, where a label covering front passenger airbag use and recommended child seating positions may be missing, which could lead occupants to use restraints incorrectly in a crash.
