We expect the 2024 Prius Prime will have about average reliability when compared to the average new car. This prediction is based on data from 2023 and 2024 models and the Toyota brand score.
The Reliability score is based on our latest subscriber survey of 2021 Toyota Prius Prime owners. The owner comments describe problems respondents experienced with this vehicle.

"For 4.5 months out of the year, this car is driven only once every two weeks while the family is away. It is garaged inside an uninsulated garage in a warm climate (Florida) during the summer. The battery has failed three times, in two instances requiring a tow, and has been replaced twice. The solution seems to be to keep it plugged into a battery tender when not in use. This problem does not occur when the car is driven more frequently (like every day or every other day), even over a short distance. We found that the battery would lose its charge and fail to start even if not driven for as little as 14 days. We're not certain if the summer heat or humidity (or both!) is causing the battery to age prematurely, or whether there is some other electrical issue in the car that the Toyota mechanics have not been able to identify, but keeping the 12 volt battery on the battery tender seems to do the trick at this point. It's a very big negative for me, and a challenging one because I really do love this car."
