Toyota Prius Prime

The Toyota Prius Prime is for those consumers tempted to buy a fully electric vehicle, but who aren't willing to contend with the range anxiety that typically goes hand-in-hand with owning an electric car. For anyone who can charge frequently and thus maximize the electric drive, it's a compelling car. Otherwise, using it as a hybrid compromises fuel economy. You also get a $4,500 federal tax incentive, at least for now.

Reliability

We expect the 2022 Prius Prime will be much more reliable than the average new car. This prediction is based on data from 2019, 2020 and 2021 models. Select the used car model year to see reported issues with those similar past models.

Reliability indicates how models have performed in the past, providing the basis for predicting how the vehicles will hold up in the year ahead. These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey for over 300,000 vehicles, our reliability history charts give you a rundown on how 2000 through 2021 vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system. NA indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

"once turned on and started usb NOT RECOGNIZED until its gets unplugged and reinserted..THIS ALSO HAPPENS GOING DOWN THE ROAD DURING PLAYBACK...DANGEROUS to reinsert while driving!!"

"Maps inaccurate. More than once have provided very poor directions, resulting in significant time delays and extra miles."

Anonymous, ME (2018 Toyota Prius Prime Advanced 1.8-L 4 Cyl plug-in hybrid)

"It always takes a roundabout route: never takes the most direct route. At times it says I arrived at my destination but it is several blocks away. My map is dated April, 2017, and no updates have been made available to date. I have contacted Toyota about this and never received a reason why."

Anonymous, PA (2018 Toyota Prius Prime Advanced 1.8-L 4 Cyl plug-in hybrid)

"Hard to use, difficult to interface with voice"

Charlie S., MA (2018 Toyota Prius Prime Advanced 1.8-L 4 Cyl plug-in hybrid)

"The menu is screwed up and I am unable to manually enter an address, because the enter address is unavailable (grayed out). I will have this checked the next time I bring the car in for service. I am able to enter addresses using voice. Also, fwiw, when using the bluetooth on a long trip to play music on my iPhone, the screen kept blacking out and the system rebooted. Will have this checked also."

M A., NJ (2018 Toyota Prius Prime Advanced 1.8-L 4 Cyl plug-in hybrid)

Air or water leaks

"Leaked with every rain. Both dealer and Toyota distributor treated us like dirt, refused to talk to us and physically restrained us from discussing problem. Kept car over 30 days, but won't inform us what repair if anything was performed. Refuse to answer our letters asking about repairs. We bought only Toyota for 40 years, bt never again."

Other/unsure

"After a heavy rain, my car started warning me about objects that weren't there. I had a couple of run-ins with the manager. I looked it up and found others had the same problem, and finally filed a complaint with the BBB. There was a recall. It's been fine ever since."

Anonymous, BC (2018 Toyota Prius Prime Plus 1.8-L 4 Cyl plug-in hybrid)

"Because of the sensor problems explained earlier, the forward collision warning was appearing for no reason (in the dark, in the rain...terrifying!) Thank goodness, it's been fixed!"
