The 2019 Toyota Prius Prime is the plug-in version of the fourth-generation Prius, running the 1.8L Atkinson-cycle four (2ZR-FXE) alongside a larger lithium-ion pack and an onboard charger that the standard hybrid does not carry. Those parts change how the car is diagnosed: state-of-charge behavior, EV-mode transitions and charging faults sit on systems a conventional Prius has no equivalent for.

Known issues on the 2019 Prius Prime. One recall is on federal record for this model year, NHTSA campaign 19V544000, and it covers the electronic stability control (ESC) system. The reported consequence is deactivation of the vehicle stability control system or a loss of braking assist. The campaign was not specific to this car: Toyota filed it across a range of 2019 Lexus and Toyota models together with the 2019-2020 Prius Prime and the 2020 Corolla HV. Owners have filed 11 complaints against the 2019 Prius Prime, and Toyota has issued 85 technical service bulletins for it.
Chasing a stability-control warning that keeps coming back, or doing a brake or hybrid-system job to spec, means working to Toyota's own figures and sequences for this 2019 Prius Prime rather than to generic hybrid guidance.
