2018 Toyota prius prime common problems

The most-reported problem areas across all 15 owner complaints filed with NHTSA — and what to check before you buy.

Power Train
Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.
Air Bags
Confirm the airbag light turns on then off at startup — if it stays lit there's a fault (costly, and a safety risk). Check for signs of prior deployment.
Fuel/propulsion System
Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
Visibility
Test wipers, washers, defrosters and all mirrors. Check the windshield for cracks and any camera/sensor for fogging or faults.
Structure
Inspect for rust, fresh undercoating, mismatched paint, uneven panel gaps and any sign of prior collision or frame repair.
Vehicle Speed Control
Test cruise control and throttle response, and watch for any hesitation or unintended acceleration.
