Owners have filed 127 complaints
about the 2017 Toyota Prius with NHTSA between 2017 and 2026.
The largest single group is the windows, mirrors & wipers.
Across this model's run it ranks 13 of 25 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 10
Against the median year of the Toyota Prius. 50 means typical for this

When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2017 Toyota Prius
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Recalls on the 2017 Toyota Prius
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

Recall 202172355,683 units in Canada
Electrical
Issue: This recall is for certain block heater kits installed on certain vehicles or sold as accessories at Toyota or Lexus dealerships. On certain vehicles, the engine block heater cable may not have enough heat protection and could be damaged by high temperatures. If this happens, the cable could short circuit while plugged in, and cause the wiring to overheat or melt. Note: This recall only affects the following block heater/cord part numbers: C014003034 PK5A408J09 PU14000904 C014003151 PK5A408J13 PU14000905 C014000885 PK5A489J11 PU14000907 C014000888 PK5A489J22 PU14000909 C014000907 PK5A410H00 PU14000911 C014100904 PU14000900 PU14000913 C014100907 PU14000901 PU14003571 C014100911 PU14000902 PK5A489J14 PK5A408J05 PU14000903 Safety Risk: Engine block heater wiring that overheats or melts could create the risk of a fire. Corrective Actions: Toyota recommends that you should stop using the engine block heater immediately. Toyota will notify owners by mail and instruct you to take your vehicle to a dealer to disable the engine block heater. For some vehicles, the corrective actions for this recall are under development. For others, a new engine block heater cannot be installed, and the owner will receive a refund of the purchase price of the engine block heater.
Recall 20194341,226 units in Canada
Electrical
Issue: On certain vehicles, a connection in the main wire harness may have been damaged during assembly. This could cause hybrid drive system to shut down, and result in a loss of power to the drive wheels. If this happens, an error message will display on the instrument panel and a warning chime will sound. Note: This recall only affects vehicles which had the seat heater installed at the port facility. Safety Risk: A loss of power to the drive wheels could increase the risk of a crash. Corrective Actions: Toyota will notify owners by mail and instruct them to take their vehicle to a dealer to repair the wire connections.
Recall 20184777,200 units in Canada
Electrical
On certain vehicles, the hybrid vehicle Power Control Unit connector cover could come into contact with the wiring harness and could cause wear on the wiring insulation. If bare wires become exposed, an electrical short circuit could occur, which could increase the risk of fire causing injury and/or damage to property. Correction: Dealers will inspect the wiring for damage and, as necessary, install protective tape or replace the wire harness assembly with a new one, which includes a protective sleeve.
Recall 201736339,189 units in Canada
Electrical
On certain vehicles, the electrical power cords of some dealer installed block heaters may have been improperly manufactured, causing the wires to contact each other, resulting in a short circuit. A short circuit could lead to a fire which would increase the risk of injury and/or damage to property. Correction: For vehicles where the subject block heater was approved for installation, the dealer will replace the block heater assembly with a new one of an improved design. For vehicles where the subject block heater was not approved for installation, dealers will remove the block heater assembly. In the interim, until the remedy can be performed, dealers will cut the plug end from the block heater cord to disable the block heater's operation.
Recall 20165012,780 units in Canada
Brakes
On certain vehicles, the parking brake cables may disengage from the crank lever at the rear caliper. This could cause the parking brake to become inoperative. If this occurs and the transmission is left in a gear other than ‘Park’ while the ignition is on and the driver leaves the vehicle, the vehicle could roll away, increasing the risk of a crash causing injury and/or property damage. Correction: Dealers will install a clip at the parking brake cable end to prevent the cable from disengaging from the rear brake caliper crank lever.

For the second time (first in 2019) I was seconds and maybe two feet from stopping the car to park when, with my foot on the brake, the car suddenly and without warning lunged forward at what seemed like full throttle. The first "crash" was in my driveway. The force was shocking and took off the front of the car. I insisted Toyota investigate and they ultimately denied any liability. After the car was allegedly repaired, I started noticing another phenomenon: every time I would slow down to brake--approaching an intersection or stop sign, etc.--the car would briefly lunge forward before the brakes engaged to stop the car. I reported this to the dealer 2-3 times and each time I was assured that this was "normal" for a hybrid transitioning from gas to electric at a lower speed. Two weeks ago, with a friend in the car, I was pulling into a parking space, foot on the brake and about to stop, when the same thing occurred: without warning, the car lunged forward, at what seemed like full throttle, and crashed into a low concrete wall. Had it been seconds later, we would have had our seatbelts off and gone into the windshield. There were injuries. FYI, I have a pretty much perfect driving record and log thousands of miles each year. I had ZERO problems with the Prius I owned prior to this one. I will never drive this car again.

I DROVE UP AN INCLINE INTO THE "DRIVEWAY" OF THE HOLIDAY IN IN DOWNTOWN SAN DIEGO, PULLED UP INTO A SMALL CIRCULAR AREA/DRIVEWAY WHERE YOU CAN REGISTER FOR YOUR ROOM OR PICK UP OR DROP OFF PEOPLE. MY FOOT WAS ON THE BRAKE, I WAS STOPPING THE CAR TO PICK UP MY DAUGHTER AND HER BOYFRIEND. AND THE CAR TOOK OFF ON IT'S OWN. I TRIED DESPERATELY TO USE THE BRAKES, BUT THEY WOULDN'T WORK, SO I KEPT DRIVING AROUND THE CIRCULAR DRIVEWAY TO KEEP CONTROL OF THE CAR WHILE I KEPT TRYING TO STOP THE CAR TO NO AVAIL. THE CAR KEPT ACCELERATING AND SCREECHING AROUND THE DRIVEWAY AND THEN I FINALLY LOST CONTROL AND THE CAR HIT A WALL TO MY RIGHT, THEN MOVED A BIT FORWARD AND BUMPED INTO A CURB ON THE LEFT AND FINALLY STOPPED.MY OTHER DAUGHTER WAS IN THE PASSENGER SEAT.WE WERE BOTH TERRIFIED! I CONTACTED TOYOTA AND FROM THE TIME OF THE ACCIDENT (10/28/19) TO THE TIME I WAS ABLE TO TALK WITH A PERSON IN THEIR CLAIMS DEPT OR RATHER RECEIVE AN EMAIL RESPONSE, IT WAS 64 DAYS LATER (10/31/19). AND THAT IS ONLY BECAUSE I CALLED THEM. I TALKED TO SEVERAL CASE MANAGERS ON DIFFERENT DAYS WHO SEEMED UNHELPFUL UNTIL FINALLY ONE OF THEM GOT IN TOUCH WITH THE CLAIMS DEPARTMENT AND TOLD ME THEY WOULD CALL ME. TOYOTA WILL NOT TAKE ANY RESPONSIBILITY FOR THIS AND I AM REALLY UPSET THAT NOW I WILL HAVE AN ACCIDENT ON MY RECORD AND MY INSURANCE WILL INCREASE SIGNIFICANTLY FOR SOMETHING THAT ISN'T EVEN MY FAULT! I AM AN EXCELLENT DRIVER AND HAVE NEVER HAD AN ACCIDENT THAT WAS MY FAULT. I WAS ALERT AND COHERENT AS WAS OBVIOUS TO ALL OF THE PEOPLE I SPOKE TO DIRECTLY AFTER THE ACCIDENT. MY DAUGHTER, IN THE PASSENGER SEAT, WITNESSED ALL OF MY ATTEMPTS TO USE THE BRAKES TO STOP THE CAR.

The catalytic converter heat exchanger failed internally, causing coolant to leak into the exhaust system. Symptoms included white smoke from exhaust and coolant loss with no visible ground leak. This is a documented factory defect per Toyota Technical Service Bulletin T-SB-0135-19 affecting 2016-2019 Prius models. Toyota has denied warranty coverage despite the vehicle was originally bought & spent its entire prior operational life registered in New York, a state covered under Toyota's full 15-year/150,000-mile emissions warranty. Defect was confirmed by an authorized Toyota dealership, in PA. Vehicle had approximately 83,104 miles at time of diagnosis. Manufacturer denied coverage and is forcing the customer (me) to pay a huge amount for this very well known & defective case. MOST IMPORTANTLY ITS dangerous and unsafe for all the cars our there too, since it is very well known that at a certain point this will happen, but despite TOYOTA never sent a RECALL. Due to this, engine light goes on & off, refrigerant is flammable and leaks in the exhaust pipe happens with this specific case, which ultimately could catch on fire, while the vehicle is moving or stalling. Lots of white smoke comes out of the car that directly impact the environmental aspects, and above all, people owning such vehicle, will be running into this issue, which will 100% put the safety of owner and anyone close in proximity to their vehicle at RISK. PLEASE ADD RECALL WITHOUT CAP for ALL SUCH TOYATA PRIUS due to flammable refrigerant leak inside the car engine components, and proven via strong white smoke coming out of exhaust that has the potentially to put the entire car on fire, specifically.

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.

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.

Several unknown warning lights were illuminated. The vehicle failed to restart, and was towed to the dealer, where it was diagnosed that the head gasket was blown, causing damage to the engine. The dealer informed the contact that the engine needed to be replaced. The vehicle was not repaired. The vehicle was taken to an independent mechanic, where the same assessment was made. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that they could not assist because the vehicle was out of warranty. The failure mileage was approximately 80,000.

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.

When filling gas, a near-empty Prius overflowed almost immediately, splashing fuel over the car, the ground, tires, and my feet! Gas is flammable and not good to get on one's skin. Firestone experienced/certified repairman said that he's repaired many Toyotas with the same problem. No advanced warning was presented. Last time I filled it before this incident it worked fine. Technician said that the air-exhaust that permits air to escape while gas is being delivered to the tank had failed to work properly, causing the fuel to spew back up the gas line and on to the car/ground. He had to order a part from Toyota and replace it. This cost me $337 for part and labor. I believe this is a malfunction that Toyota should cover. This part should not fail as it could start a fire and contaminate the car, ground and put petroleum on people.

ELECTRICAL SYSTEM
For the past year or so we have had issues with the vehicle not starting properly. If we leave the radio, wipers, heater, or air conditioner in the ON position when we shut the car off, or a window down a little on a hot day, a sensor triggers a Low Battery error code. We have had the battery checked and it is NOT low. When this happens to start the car we need to get a jumpstart from someone. This limits where we feel safe driving to as in a remote place where not many other people and cars are it would be more difficult to find someone to give us a jumpstart. On occasion, we have had to call a towing service to come to help us, which requires sometimes a long wait. The car starts right up once the connection to the other vehicle's battery is made. We should not need a checklist to make sure everything is turned off before we leave the car to avoid this non-starting issue.

SERVICE BRAKES
On 9/14/22 I was almost a hundred miles from my home in Sherrill, NY on Rte 81 south, approaching the bridge in Binghamton, NY when I heard a loud ringing noise. At first I thought it was my phone; then I thought it was a police vehicle; then a construction noise. I finally faced the fact if was coming from my 2017 Prius which had just reached 20,000 miles. I was in heavy traffic but managed to pull over and walk around the car as the noise seemed to be coming from the rear. I saw nothing amiss. I managed to drive another twenty minutes to Great Bend, PA and just before I pulled into the parking lot at McDonalds the noise stopped. I called Nye Automotive in Oneida, NY which had sold me the car and talked to a mechanic who said he had no experience with a ringing noise. Proceeding cautiously I drove 135 miles to Quakertown, Pa where my son diagnosed the problem as the brake pad on the drivers side rear wheel that had tilted and was banging against the rotor. My son replaced the brake pad and next day we drove to Long Beach Island, NJ, stopping to check for heat coming from that wheel. It was fine. When I got back home to Sherrill I could found the email of Mark Templin, CEO of Toyota who gave me the number of [XXX], a Toyota executive. I have been driving for sixty years and had never encountered a tilted brake pad. I am so easy on brakes that mechanics marvel that I can get to over 50,000 miles before work needs to be done. I am concerned that the ringing-clanging noise alone could cause an accident. Having had a bee and a mouse in the car previously I remained in control but could have reacted badly. I told [XXX] that I thought perhaps Toyota would like to see who had made the brake pads. I had heard of airbags and other components purchased by many car makers having caused problems in the past. Mr. Wilson didn't seem interested. Also, since my car was beyond the 3-year warranty he felt Nye wanting to charge me to look at the car was appropriate.

SEATS
The driver's side car seat automatic seat adjustment (backwards/forwards) failed all of a sudden with no warning. It was working when I parked the car to go into an office for an appointment. When I came back out to the car, it wouldn't work and was making strange noises. I called the dealer and they said to bring in the car to be looked at. This is a safety issue because it was hard to reach the pedal to drive the car without pillows pushing me forward in the car seat. The car was taken to the dealer twice and I was finally told that the track the car goes forward and backward on was worn out and the motor would need to be replaced. I was quoted $3K for the repair because the warranty had expired and the car seat needed to be removed to make the repairs.

VEHICLE SPEED CONTROL
I had just changed from the right-hand lane to the center lane of a six-lane expressway when my vehicle lost power and i was able to move over to the right hand shoulder of the road. The accelerator pedal did not work and I just coasted to the side of the road. I noticed that a red warning saying something about RADAR flashed on the instrument panel when this happened. I turned off the vehicle and tried to restart it, but nothing happened. I then texted the person who was expecting me and explained the problem. Since I had just taken the car to the dealer for its regular 40,000 mile service four days earlier, I intended to call my dealer to ask them what to do. All of this took about 10 minutes with the engine turned off. Before doing this, I again tried to restart it. It started and I inched it forward on the shoulder of the road. Since I did not feel safe parked on the shoulder, I merged into traffic and took it to another Toyota dealer. They said that they could not look at my vehicle to diagnose what might be wrong because all their technicians were going home at 4 pm. I drove to my son's house and he suggested that I report this to you. Something similar happened to him when he was driving this same vehicle about six month ago. He was driving on a city street, did not notice any dashboard warning, and took it to this same dealer. They were not able find anything wrong. I felt I should report this since this is the second time this vehicle suddenly lost power. My incident happened when I was driving at expressway speed and could have caused a serious accident had I not been able to coast to the shoulder of the road.
