NHTSA recall 18V-579 covers certain 2016 to 2018 Prius models. Part of the engine wire harness at the hybrid power control unit can rub its cover, wear and short circuit. That raises the risk of a fire. Dealers inspect the harness, replace it if damaged, and add a protective sleeve or tape, all free.
WE CHECK We check the VIN for an open recall and look at the harness near the power control unit for wear or burn marks.

NHTSA recall 17V-658 covers certain 2016 Prius models. A capacitor inside the hybrid inverter may not have been bolted down, so driving vibration can damage it and shut down the hybrid system. Dealers replace the inverter for free. Recall 21V-734 covers certain 2022 Prius models whose engine computer software may falsely detect an error and shut down the hybrid system. Dealers update the software for free. Both can cause a loss of drive power.
WE CHECK We check the VIN for open recalls, scan the hybrid system for stored codes, and road test.

NHTSA recall 19V-544 covers certain 2019 Prius models. The brake booster pump may fail, which can turn off stability control and cut brake assist. Dealers inspect and replace the pump if needed, free. Separately, a Toyota tech tip for 2016 to 2018 Prius models lists cases with several warnings at once, such as the ABS light, a low brake force message and a brake light that does not work. Some 2016 owner complaints coded to service brakes in NHTSA's file report similar warning lights.
WE CHECK We check the VIN for an open recall, scan the brake and stability systems for codes, check the brake lights, and test pedal feel on the road test.

NHTSA recall 16V-672 covers certain 2016 Prius models built from November 30, 2015 to June 14, 2016. The front passenger air bag inflator may partly inflate on its own. Dealers replace the air bag assembly for free. Recall 18V-085 covers certain 2016 Prius models whose air bag pressure or acceleration sensors may fail, so the side curtain or front air bags may not deploy. Dealers replace the sensors as needed, free.
WE CHECK We check the VIN for open recalls and watch the air bag light.

NHTSA recall 16V-741 covers certain 2016 and 2017 Prius models built from August 6, 2015 to October 3, 2016 with a foot parking brake. The cable may come loose. If the car is left out of Park with the system on and the driver gets out, it may roll. Dealers install a clip on the cable end for free.
WE CHECK We check the VIN for an open recall and test that the parking brake holds.

Toyota bulletin T-SB-0135-19 says some 2016 to 2019 Prius models can leak coolant at the front exhaust pipe heat exchanger. Signs are a low coolant level, a check engine light with code P148F00, or poor heater output. Toyota updated the part. The bulletin says the repair falls under the federal emission warranty of 8 years or 80,000 miles from the in service date, and longer in some states that follow California rules.
WE CHECK We check the coolant level, scan for code P148F00, check heater output, and look under the car at the front exhaust pipe for coolant.

Toyota bulletin T-SB-0241-17 says some 2016 to 2019 Prius models with a NiMH hybrid battery may have reduced power when pulling away from a stop. It can happen after long downhill drives or hot weather, then a 1 to 2 hour stop. The battery gauge may also stay at one bar. The fix is a hybrid control computer update for cars built before a production change.
WE CHECK We road test from a stop, watch the hybrid battery gauge, and read the records for the software update.

Most of the 42 complaints coded to visibility for the 2016 Prius in NHTSA's file describe the windshield cracking, often with no clear impact. The 2017 file shows the same pattern. We found no recall or warranty extension for it.
WE CHECK We look over the whole windshield for cracks and chips, and ask whether it has been replaced and with what glass.

NHTSA recall 19V-876 covers certain 2019 Prius models whose main meter can short out and go blank, losing the speedometer and fuel gauge. Dealers replace parts as needed, free. Toyota campaign J0R reprogrammed the clearance sonar on certain 2016 to 2018 cars because it could apply the brakes in some car washes. Campaign 21TC06 updated the pre-collision brake assist software on certain 2021 cars. Both updates are free.
WE CHECK We check the VIN for open recalls and campaigns, watch the dash for blank screens, and scan the safety systems for codes.

Toyota extended the hybrid battery warranty to 10 years from first use or 150,000 miles for 2020 model year hybrids, and the Prius is on its list. Toyota says it covers later owners too. Other hybrid parts stay at 8 years or 100,000 miles. Earlier Prius models have the older 8 year or 100,000 mile coverage.
WE CHECK We note the in service date and mileage so you know how much battery coverage is left, and scan the hybrid system for battery faults.

A TSB is a note the maker sends to dealers about a known fix. They are not recalls. We check the bulletins so we know what to look for:
Cold-start noise, drivability, and idle issues for this vehicle. We test for each.
Shift quality and transmission fluid updates. We drive every gear.
Locks, wipers, infotainment, and trim items. Small, but good to know.
Bulletins stay with the maker, so we pull the current list for this exact vehicle during the inspection and tell you what applies.
