2019 Toyota Prius: engine and transmission complaints
NO ELEVATED SIGNAL
21%
7 of 33 relevant owner complaints are about the engine, transmission or fuel system
No elevated drivetrain complaint concentration in the available NHTSA records for the 2019 Toyota Prius. Engine, transmission and fuel system account for 21% of relevant complaints.
Better than 85% of the 1,230 model years we track (2010–2023).
Excludes 5 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 18%).
Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.

This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2019 Toyota Prius
No elevated drivetrain pattern for this model year. That describes the model, not the car in front of you.
Get an independent pre-purchase inspection from a mechanic you choose.
3 recall campaigns on this model year. Whether a specific car still has one open depends on the VIN; the report checks that.
