Recall Details for the 2015 Toyota Prius C
The following 1 recall has been issued for the 2015 Toyota Prius C by NHTSA:
Summary: Southeast Toyota Distributors, LLC (SET) is recalling certain model year 2015 Toyota Prius C vehicles manufactured April 20, 2015, to June 30, 2015. In the affected vehicles, the Tire Pressure Monitoring System (TPMS) may be improperly calibrated and, as a result, the TPMS may fail to warn the driver that the tire pressure is low.

Consequence: If the vehicle is driven on underinflated tires, the tires may fail. Sudden tire failure increases the risk of a crash.
Remedy: SET will notify owners, and dealers will re-calibrate the TPMS, free of charge. The recall began on September 15, 2015. Owners may contact SET customer service at 1-866-405-4226. SET's number for this recall is SET15E.

Car feels like it lunges forward while braking over bumps. I have learned this is a known manufacture defect with the Brake Booster and Brake Actuator which Toyota is refusing to replace outside of 10 years from manufacture date.
