2021 Toyota Prius prime problems
The Toyota Prius Plug-in Hybrid (often abbreviated as the Prius PHV and known as the Prius Prime in North America, South Korea, and New Zealand) is a plug-in hybrid liftback manufactured by Toyota. The first-generation model was produced from 2012 to 2016. The second-generation model has been produced since 2016. Production of the third-generation model began in 2023.
The Prius Plug-in Hybrid was the second most sold plug-in electric car in 2012, and became third-best all-time in December 2014. As sales declined after the end of its production, the Prius PHV fell to fifth place in the global ranking by November 2015, after being surpassed by both the Tesla Model S and the Mitsubishi Outlander PHEV. As of December 2017, sales were led by North America with 66,800 units, followed by Japan with 48,800, and the European market with 13,100 units. The U.S. was the leading country market with 65,703 units sold by 2017. As of December 2019, cumulative global sales of both Prius plug-in generations totaled 209,000 units.
Concept and demonstration models
The Prius Plug-In Hybrid Concept was exhibited at the September 2009 Frankfurt Motor Show, the October 2009 Tokyo Motor Show, and the December 2009 Los Angeles Auto Show. The vehicle was based on the third-generation Toyota Prius (model XW30) but outfitted with 5.2 kWh lithium-ion batteries. The selected battery capacity is the minimum required for a vehicle to be eligible for the U.S. federal tax credit of US$2,500, which under the American Clean Energy and Security Act of 2009 is applicable to the first 200,000 plug-ins sold by an automaker.
After displaying the concept version in these three shows, a global demonstration program involving 600 pre-production test cars began in late 2009 and took place in Australia, Canada, China, France, Germany, Japan, New Zealand and the United States. The demonstration vehicles were made available for lease to fleet and government customers, of which, 230 were delivered in Japan beginning in late December 2009, 125 in the U.S. by early 2010, and 200 in Europe in spring 2010. All program vehicles were equipped with data tracking devices to allow Toyota to monitor the car's usage for further development of the plug-in hybrid system.
The pre-production Prius Plug-in used three different batteries: two added batteries to provide all-electric drive and the standard hybrid battery which engages when the first two are depleted, allowing the car to operate like a regular hybrid Prius. According to Toyota, when the vehicle started, it operates in all-electric mode, drawing electrical power directly from the first battery pack. When the first battery was depleted, it disconnected from the circuit and the second pack engaged. When the second pack was depleted, it disconnected from the circuit and the vehicle defaulted to conventional hybrid mode, using the main battery as the sole electrical power source. Pack one and pack two would not reengage with the circuit until the vehicle was plugged in and charged.
According to Toyota, the demonstrator was rated at 1.76 L/100 km (134 mpg‑US; 161 mpg‑imp) on the Japanese JC08 cycle with a combined efficiency based on 43.6% of driving in EV mode, and CO2 emissions of 41 g/km. Fuel efficiency operating as a gasoline-electric hybrid, like the regular Prius, is 3.3 L/100 km (72 mpg‑US; 86 mpg‑imp) with CO2 emissions of 76 g/km.

We had the pleasure of meeting Martha G at 9 am sharp, and she was incredibly professional, friendly, and courteous throughout the entire sale transaction of our Prime XLE. We would like to give a special shoutout to Charlie Park, the Manager, who went above and beyond to resolve an issue. He even said, 'The customer is always right, and you are the customer.' When I thanked him, he humbly replied that there was no need to thank him. This was, without a doubt, the best car buying experience we've had in the last 20 years.

That's a great car! It's perfect for shorter trips, with an all-electric range of up to 25 miles on a full charge.

I had to undertake a major regional search for a 2020 Toyota Prius Prime. But it was worth it! I found a fantastic vehicle - just what I was hoping for. The car basically looks new, has low mileage, and the price was reasonable. That was such a great find!

Hi there! Have you considered the budget for installing a 240-volt charging station at home?
-
The car sounds great! It's impressive that you're getting up to 35 mpg in town and have had no issues with 97 mpg after almost 16000 miles, especially with half of those miles on the interstate. It's good to hear that the economy has stayed the same after 25,000 miles, which is a major concern for many people. I understand your frustration with the navigational system, but overall it sounds like you're enjoying your car.

If fuel mileage is a top priority for you, then this vehicle is definitely worth considering. However, if fuel economy is not a major concern, this car may not be the best option. The driving experience can be unpleasant and there is a high level of interior noise at highway speeds. Additionally, the luggage space is compromised by the large battery that only provides about a 25 mile range. Lastly, the infotainment system could be improved.
Leone Leffler 2024-09-04
The 21 Prius Prime is a comfortable and roomy car, but it has some major drawbacks that should be considered before making a purchase. The price ranges from $28-36k and the fuel mileage is not much better than a plain-jane hybrid that costs thousands less. However, the federal rebate can help offset the cost. The EV-only options are nice, but they come at a premium that may not be worth it. When fully charged, the ride is brisk, responsive, and agile, providing a pleasant driving experience. However, wind and engine noise can be pronounced and may detract from the overall experience. The hatch/boot space is extremely small, limiting the amount of luggage or cargo that can be carried. Additionally, there is no rear window wiper, which can be more annoying than it seems at first glance. Despite these concerns, the LE version (with no adjustable seats, small infotainment, and cloth seats) used and with low miles may be the best option for those looking to save money. A used 20/21 car with a few thousand miles for 18K, with EV-only options, might be the best option if you must have a Prius over an Ionic. Overall, it is important to carefully consider the drawbacks before making a purchase.

I recently purchased my third Prius, the 2021 plug-in model. While my previous two hybrids were great and the service was excellent, I have to admit that I'm not entirely satisfied with this latest purchase. Unfortunately, I didn't receive all the necessary operating information when I bought the car, which made it difficult for me to understand and program the controls and settings. The placement of the controls is also quite inconvenient and even dangerous, as one must look down towards the floor to determine which button is which. The instruction manual is quite lengthy, with 650 pages of confusing acronyms and symbols. However, the local service department is currently working to sort it out. I've been informed that this model has 27 computers, which may be a bit excessive. Despite these challenges, I'm confident that with some patience and assistance, I'll be able to fully enjoy my new car. I would also like to advise others to be aware of the federal tax rebate, which is currently around $2500, rather than the $7500 that some may have been led to believe.

I recently purchased a Prius Prime, my first hybrid or EV, and found it to be more complex than I expected. The initial programming only allowed for basic driving, and I received limited instruction on how to start the car and put it in gear. Unfortunately, there was no gauge for available motive battery power on the dashboard, nor was there any explanation of how the battery would be charged. It seems the manufacturer assumes that drivers will use the battery power until it runs out, and then switch to the gasoline engine until they can learn how to operate the many functions of the car from the Owner's Manual. Speaking of which, the manual is poorly written and organized, and seems to be intended to show off the many complicated ways that the various screens can be programmed depending on the car's features. Operating the car is complicated by its many combinations of motive power, and there is no basic set up installed initially. I have spent hours poring over the manual and am still not done. Proper maintenance of a hybrid car requires a balance between operating the engine and the electric motor, which is not required of the owner of a car with a single motive power. The traction battery requires particular attention, which may be unknown to those who have only operated gasoline-powered cars. While the car may not be ideal for retired persons like myself, it is perfect for commuters. It is important to garage the car, as extreme heat or cold can adversely affect the battery. For local driving, an EV may be more advantageous than a hybrid, as engine maintenance is not a concern. However, for road trips, a hybrid is a must, as the gasoline engine can continue when no convenient overnight charging station is available near a motel or hotel.
