In the 2017 Prius Prime when the car switches from Electric power to gas the car frequently fails to allow you to accelerate. It is like you are stuck in neutral on the freeway, taking your foot off of the acceleration pedal and pushing it down doesn't always fix the issue. The accelerator foot pedal can be completely down to the floorboard as you are losing speed. The safety issue is that you are losing speed, and on the freeway and the car doesn't recover losing some control. I have taken the car to the Toyota delearship and when taken in that say it is a software update, but this continues to happen. There is no real notification when this will occur as the battery milage switchover is often misreported by the car.

I have a 2017 Toyota Prius Prime advanced. It has the large infotaiment screen that is where I have to access many items. Often, seemingly randomly, the screen shuts down and reboots itself. During the time it is rebooting I do not have any access to the controls. It gives no warning when it is going to reboot. I have seen other Toyota recalls for a similar problem on the RAV4 vehicles and I wonder if it is related.

During hot temperatures and after coming to a full stop, the car stalls/hesitates significantly (5-6seconds) when pushing the gas pedal. The car eventually proceeds but the issue reoccurs. It can only be intermittently reproduced and no codes are shown on the car dashboard. Mechanics are unable to identify the source of the issue so it cannot be resolved.

Toyota has a very well known issue with head gasket failures right around 140k miles that they refuse to address. This is my second Prius and my second failure right at 140k miles. They refuse to acknowledge it, but the advisors in the service department say that's their "bread and butter." They repair bad head gaskets on priuses for $5k all day long. Toyota needs to do right by their clients.

Background Toyota has received reports of paint peeling on certain vehicles with the original factory-applied Blizzard Pearl or Super White paint colors. These reports indicate that vehicles with these specific paint colors, applied during the vehicle manufacturing process, may experience paint peeling on exterior metal body panels. Although the original factory paint is covered by Toyota’s New Vehicle Limited Warranty for 3 years or 36,000 miles (whichever comes first), we at Toyota care about the customers’ ownership experience. Toyota is providing coverage for repairs related to the condition described above. The following information is provided to inform you and your staff of the program notification schedule and your degree of involvement. Customer Support Program Coverage Details This Customer Support Program provides coverage for involved vehicles with the original factory Blizzard Pearl or Super White paint. The covered condition may occur when sunlight over time degrades the adhesion between the factory-applied paint primer coat layer and the base metal electrodeposition layer causing the paint to peel from the metal body panel. If the condition is verified, the specific panel affected will be repainted. · The Primary Coverage will be offered until December 11, 2022, regardless of mileage. · After the Primary Coverage, the Secondary Coverage is applicable for 10 years from the date of first use, regardless of mileage. My vehicle is a 2017 Toyota Prius prime with Blizzard pearl 070 paint and I am experiencing terrible paint chipping. My hood, roof, and A Pilars are starting to rust. When I tried speaking to Toyota dealerships and corporate about this issue they refused to help and said there's nothing they can do because my vin doesn't match the recall. The fact that this same paint code is showing such wear despite my vehicle being newer that the recalled vehicles should automatically make me a candidate for a paint replacement on the damaged areas.

While driving I heard noises, like “flap,flap,flap”. Pulled over to look at the tire and saw that the tire was peeling. Changed to the donut spare tire and went to “Firestone” 5 days later to have a new tire put on because the original service shop, “Mr King auto services center”, would not take any responsibility for a the tire that was purchased and installed by them 6 months prior. I went to Mr Tire 2 days after this happened and was basically told there was nothing they could do and said it was the alignment. Firestone said my alignment was fine and gave me paperwork to show what was checked. Cooper P215/50R17 (90W)

While driving the speed limit of 70mph on a major highway, the sunroof on my 2017 Toyota Prius exploded. There was no warning of any kind: no other traffic nearby so no rock or debris from another vehicle; no overpass or bridge so nothing from above; it was a mild sunny day of 76 degrees so not a weather factor; and by the angle of the glass that remains being in an outward position rather than inward, reveals to me that it was from inside out, not from outside in as if it were a rock hitting. It just exploded. I was the only person in the car. Thankfully, the visor was shut on it or the shattered glass would have caused injury and of greater serious concern is just the sudden sound of what sounded like a bomb going off over my head was enough to cause a reaction which easily would result in an accident. It was a terrifying experience! I was lucky no other vehicles were nearby and could react and safely get off the road. I called 911 immediately and reported it. I have read many such claims from other Toyota owners online (see ToyotaNation.com and search by "exploding Sunroof") and even from a technician at my nearby Toyota Collision Center that it just happened to a friend of theirs also. This is not a one time issue. When I took the car to the Collision Center for an estimate and inquired about the damage, they could find no recall on it by Toyota. This is certainly a dangerous and hazardous issue that needs to be addressed asap before someone is seriously hurt or there is a fatality.

Dashboard pop up came up saying that the grille shutter is inoperable to visit a dealer. Went online and noticed there were recalls for my Prius year and because emissions is affected I contacted Toyota financial customer service who said to go to a dealer and that they would fix no charge. Went three times to the dealer and they did not want to honor the recall. Charged me $200 to run diagnostics on the vehicle and confirmed that the code that was being recalled matched. They made excuses and in the end did not fix. The pop up appeared March 2024 and since then I now have another pop up appear about the hybrid system overheating due to them not fixing. I went to a local mechanic who said it was the dealers responsibility since there are service bulletins but they do not want to help. The car has stalled out on the freeway almost leaving me to get hit and my fuel has gotten worse.

Jbl touchscreen 11.6 on Prius prime plugin 2017 has capacitive buttons like FM AM SPEAKER/Audio, and resistive buttons like Volume and Sufio not registering a finger touch or pressure. All other icons on touchscreen work and respond. Bluetooth works but no sound when a text message is read from my iPhone. Started when heat index was 107 on June 23. With climate change I am concerned that EV and PHEV touchscreens may need to be recalled to prevent this kind of failure. Mechanic said it WAS NOT FUSES OR BATTERY, and AICHATGBT proffered a software glitch or a neede update

Each time I use the USB port behind the cup holders, my vehicle's electrical system goes through a power-down cycle. This has happened several times over the years while I was driving. I no longer use that particular USB port for safety reasons. I reported this to my Toyota dealer, but they could not replicate the problem while I was there, so nothing was ever done. My younger son was driving the car and nearly had a wreck when the electrical system power-cycled while he was driving. He has been instructed to not use the USB ports.

On 10/16/23 I was turning slowly into a parking spot and my car suddenly accelerated without my pressing the accelerator. I slammed on the break and the car stopped. It was frightening because I could have hit someone or something but luckily the car stopped before that happened. I believe that this was a malfunction of the accelerator. This has not been checked or reported to anyone yet but I will be calling Toyota to have it checked. There have been no warning messages.

My 2017 Toyota Prius Prime has experienced a second windshield crack perhaps hit by a small object, which I didn't notice at all. The crack is a "L" shape, about 15 in at each direction. The firs Windshield crack was happened about a year ago. Toyota dealer replaced it with an original Toyota Windshield. I believe this particular Windshield type isn't strong enough to withstand a small stone hitting it. As I didn't notice any loud popping sound during driving

While filling my Prius with gas, as soon as I started pumping, it spewed gas all over my arms and shirt, as the gas would not go down the pipe into the gas tank. My mechanic explained that gasline exhaust valve was stuck causing the gas to spirt back out the intake opening. This part had to be replaced. Firestone replaced it for a total of $337.08, however, the dealer would have charged more. It was not covered as a defect issue. The experienced mechanic said that he had seen this problem on several Toyotas. This is hazardous and Toyota should repair those that exhibit this problem; also they should change their design so that the exhaust valve does not fail causing gasoline to spill on the person pumping gas and all down the side of the car onto the cement pavement.

Driver side electric Seat rail malfunction after I was hit from the rear end collision. The seat electric adjustment became inoperable. The seat rail has a small gear in the electric seat that got destroyed during the rear end collision. Is the seat designed for damping, if so why does the driver side electric seat become inoperable?
