Visibility
Reports naming windshields, glass, wipers, defrosters and mirrors.
From owner reports, verbatim
I reported issues with this car in 2018. Clicking sounds under the car which is still happening, peeling paint on exterior and inside door areas, substandard windshield that spread in a very unusual pattern when hit by a small rock. The NHTSA ID Number that was assigned to these complaints is [XXX] . None of these problems have been addressed. There are other owners that have experienced the same problems, apparently their issues have not been addressed. These problems should have been sent by you to the Toyota Corporation, but apparently was not. I have owned many Toyota vehicles and have not experienced these problems. I also own a 2012 Toyota Prius which I drive when I when I am traveling on the interstate, because I feel that the clicking noises on the 2016 Toyota Prius is a safety issue that seems to be coming from the steering section underneath the car. When traveling the speed limit on the on Interstate highways, what would be the outcome if the steering mechanisms underneath the car did not work properly. It is a shame that this safety issue has not been addressed by you, and it is also a shame that I have to drive my older toyota at these times to feel safer when driving. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
At the beginning of this week, I was checking fluid levels and upon dropping my hood, I watched a crack in the windshield extend up from the base of the windshield. Then, while I was driving, I watched the crack extend and branch into a second crack. Upon further inspection, it appears cracking started under the windshield wiper and arched downward to the base of the windshield and another a new crack extend upward. I am the only person who drives this car. I do not park under a tree or anything that might fall on the windshield. I have not experienced any rocks hitting the windshield recently. I have not driven in the rain in several weeks. The only time the windshield wipers moved recently is when I cleaned my windshield over the weekend and lifted the wipers to reach underneath. Best as I can tell, the crack started due to the windshield wiper being picked up and let back down. This concerns me a great deal considering that is not a great amount of force.
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
During summer months when temperatures are above 100 degrees when accelerating from a complete stop I can hear the engine rev and the RPMs increase but the vehicle will move at 1-2 mph. Even if the accelerator is to the floor. After 3-4 seconds the tires will squeal and the vehicle will be jolted forward then it will slowly accelerate. This happens occasionally and I have taken it to a Toyota dealership and a chain mechanic shop, neither have been able to recreate the problem. There are no warnings and no error codes. I have been stuck in the middle of intersections trying to turn left, I have not been hit, but I fear it will happen. There is a recall out for this issue on other Priuses and I believe the issue needs to be investigated further as there is another complaint on this site for the same issue and I have found it on other sites. I bought the car in fall of 2019 and this problem has been occurring since summer of 2020.
While driving vehicle on the freeway it stated braking power low, stop in a safe place, antilock brake system malfunction, pre-collision system malfunction, lane departure alert malfunction. I was almost in a major scary accident.
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
The contact owns a 2016 Toyota Prius. The contact stated that while the vehicle was on and running, the ABS and traction control warning lights illuminated, and the messages "Braking Power Low - Stop in a Safe Place”, “See Owner's Manual", "Braking Power Low - Visit the Dealer", and "ABS Malfunction - See Dealer" were displayed. The contact stated that while driving approximately 35 MPH and depressing the brake pedal, the brake pedal was firm. The vehicle was taken to a dealer, and DTC: C14B6 was retrieved, indicating that the brake booster needed to be replaced. The vehicle was not repaired; however, the code was cleared. The vehicle was then taken to an independent mechanic, where the information from the dealer was relayed that the brake booster needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 100,028.
Second time !!!! during ownership of car that brakes fail. Same problem as before Brake Actuator/Booster Failures: Multiple reports indicate issues with the ABS actuator or brake booster pump, leading to warning lights ("Braking power low", "ABS system malfunction").
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
Water pump failed without warning and caused irreparable damage to the engine ("blown" engine requiring replacement). Vehicle began to stall and not respond to attempted acceleration while traveling on 4 lane divided highway, 55 mph speed limit. One "Maintenance Required" message was received the previous week, but disappeared. This is the same message that appears for routine oil changes. No other warning messages were noted at the time of the incident, no unusual noises, and no smoke or other sign of overheating. Driver was able to steer vehicle to safety, but this failure could result in stranding on a busy, dangerous interstate highway. For such a critical piece of the vehicle (i.e., the water pump), there should be obvious warning message(s) and dedicated monitoring of the equipment.
Refer to TSB 0135-19 dealer denied repairing under the California emissions defect and performance warranty.
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
On September 2022 (at 46K) Dealer did TSB related fix on my 2016 Prius. PFA for service record. They replaced Exhaust Front Pipe, which is suggested work from Toyota PFA for Toyota Technical Bulletin. T-SB-0135-19 At 51,747 on March 1st 2023 around 8 40 am, while we are driving on highway at 70 mph suddenly Check Engine Light, Coolant light, Hybrid related lights were on Vehicle lost the control, speed was dropping luckily we could safely stop the vehicle on the shoulder no Vehicle hit us from behind. Sudden stop of engine while driving on highway at 51K miles is safety issue. Toyota dealer could not provide additional details except Engine is over heating.
When the battery cooling fan is running, the car is slow to accelerate or will not accelerate at all. The incident has happened multiple times over the past year when the temperatures are above 90. If at a complete stop, the car will not accelerate, it will only jerk forward. The car has to be turned off and restarted to be able to accelerate. If braking or reducing speed, the car will be sluggish, and I have not been able to get the speed over 40 mph. I have taken it to the dealership, but they said they could not recreate the issue, though I do not believe that they followed the directions I gave them to recreate the problem. No warning lights appear when the issue occurs, so they did not have an answer. The first time the incident occurred, I had just had the scheduled maintenance completed two days earlier and they did not find anything in the inspection that needed to be repaired. The first time the incident occurred, I was at a stop light trying to make a right turn. The incident has occurred twice when trying to pull on to the highway and accelerate up to speed.
Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
My car suddenly stopped in the middle of the road with message "Hybrid system stopped steering power low". Safety concern to this happen on the middle of road during rain or cold.
During summer months when temperatures are above 100 degrees when accelerating from a complete stop I can hear the engine rev and the RPMs increase but the vehicle will move at 1-2 mph. Even if the accelerator is to the floor. After 3-4 seconds the tires will squeal and the vehicle will be jolted forward then it will slowly accelerate.

Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
Paint is starting to peel around trunk, clear coat has peeled off of black triangle areas by rear passenger windows on both sides of vehicle. Other 2016 Prius have had a paint recall. My vehicle needs to be included in the recall.
Starting in about 2019, the exterior black panel behind the rear right mirror began peeling. Soon, the blue exterior paint on the car began to show damaged spots, lining up with the parts of the car most exposed to the sun: the roof most of all, but the top panel behind the rear window and the top of the trunk showing signs of damage as well. The beginnings of this damage are also appearing on a couple of parts of the side doors, making it clear that the underlying problem applies to all of the blue exterior paint. It seems as if the exterior layer - some sort of sealant or finish - is not holding up properly in the sun. By contrast, our red-painted 2014 Prius, which has been exposed to the same conditions but for a longer period of time - shows none of this damage. The damage is quite extensive and visible, and it's unclear to what extent the protective qualities of the paint are now compromised. The service department at the dealership has inspected the paint, as has a third-party shop, and all agree that there is a serious paint problem. The issue is available for further inspection. The safety issue here is the potential for corrosion of the body due to the compromised paint integrity.
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
My steering wheel controls, including odometer, cruise control, horn, and airbag light is on. I took it to the dealership and they said it is the spring (clocking) cable in the steering wheel. Looking up a recall there are quite a few years and models where this exact issue has been recalled on Toyotas, but the dealership says my 2016 Toyota Prius is not cover (same exact issue). I submitted a ticket through Toyota customer service but they have done nothing about this safety issue for the 2016 Toyota Prius. I see lots of blogs and complaints because the airbag default warning light stays lit, so I assume airbag is not functional. I found a site that says to put the complaint through here.
I was hit when someone ran a stop sign. Pushed into oncoming traffic and hit a truck. My Toyota Prius was totaled. No air bags deployed. Seatbelt did not tighten either. I have contacted Toyota. Someone retrieved the data from recorder. I have a copy but it was to long to send with pics. Toyota claim # [XXX] (sorry for one pic I couldn’t delete) INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).”

Suspension
Reports naming suspension components — springs, struts, shocks, control arms and related hardware.
From owner reports, verbatim
REAR SHOCK NUT COMES LOOSE AND TOYOTA HAS ISSUED TSB 0144-16, TO TIGHTEN THE NUT. THIS IS COMMON AMONG PRIUS. THIS MUST BE A RECALL OTHERWISE IT IS DANGEROUS IF THE SHOCK BECOME LOOSE. INITIALLY THE DEALER TOLD ME TO REPLACE SHOCKS BUT FORTUNATELY I FOUND OUT ABOUT TSB AND THE DELEAR FIXED IT FREE.
2016 TOYOTA PRIUS VIN#[XXX] I PURCHASED THIS CAR IN JULY, 2017 AND I AM HAVING PROBLEMS WITH A CLICKING OR POPPING SOUND UNDER THE VEHICLE ON BOTH THE RIGHT AND LEFT, REAR AND FRONT. I HAVE TAKEN MY CAR IN FOR REPAIRS 3 TIMES AND THE TOYOTA REPAIR SHOP CAN FIND NOTHING WRONG. THE CLICKING AND POPPING NOISE IS GETTING WORSE AND I AM VERY CONCERNED ABOUT THE SAFETY OF THIS CAR. I HOPE FOR THE SAFETY OF THE TOYOTA CUSTOMERS THAT THE TOYOTA CORPORATION IS TAKING THESE COMPLAINTS SERIOUSLY. I ALSO HAVE A COMPLAINT REGARDING THE WINDSHIELD. WHILE DRIVING A PEBBLE HIT THE WINDSHIELD AND IN A AND WITHIN 5 MINUTES THE LINE SPREAD AND A WINDSHIELD REPAIR COMPANY TOLD ME THAT IT COULD NOT BE REPAIRED. THERE IS A MAZE OF CRACKS COVERING THE WINDSHIELD. IF THE CAR WAS INVOLVED IN A COLLISION, I FEEL THAT THIS WOULD A DISASTER BECAUSE OF THE SUBSTANDARD QUALITY. I HAVE PURCHASED SEVEN TOYOTAS IN THE LAST 20 YEARS AND HAVE NEVER EXPERIENCED THESE TYPE OF PROBLEMS. THE PAINT ON THIS VEHICLE IS ALSO VERY POOR QUALITY, THERE ARE AREAS WHERE THE PAINT HAS COME OFF AND GRAY AREAS APPEAR. I WOULD LIKE TO KNOW WHY THERE ARE NO RECALLS AND IF THESE COMPLAINTS ARE BEING SERIOUSLY INVESTIGATED. I SUPPOSE THAT WHEN LIVES ARE LOST BECAUSE OF SUBSTANDARD WINDSHIELDS OR OTHER PROBLEMS ASSOCIATED WITH THIS VEHICLE, THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION AND THE TOYOTA CORPORATION WILL ADDRESS THESE ISSUES.

Interior & seats
Reports naming seats, latches, locks, linkages and interior fittings.
From owner reports, verbatim
The contact owned a 2016 Toyota Prius. The contact stated that while switching lanes, the vehicle was rear-ended by another vehicle driving at 30 MPH. The contact's front driver's side seat backrest inadvertently moved backward, which caused her shins to hit the dashboard under the steering wheel during impact. None of the air bags deploy upon impact. The contact later received medical attention at the hospital for injuries to her shins. A police report was filed. The vehicle was towed to a tow yard and deemed totaled by the insurance company. The manufacturer was not made aware of the failure. The failure mileage was approximately 88,000.
THERE IS AN ONGOING ISSUE WITH THE HEAD RESTS ON THIS VEHICLE. THE DEFAULT SETTING IS MUCH TOO FAR FORWARD, CAUSING A FORWARD HEAD AND NECK POSTURE, RESULTING IN HEADACHES, NECK PAIN, ETC., AND MAKE IT VERY UNCOMFORTABLE TO DRIVE, AND DIFFICULT TO CHECK BLIND SPOTS. IT ALSO FORCES THE DRIVER'S HEAD VERY CLOSE THE AIRBAG, WHICH IS SUPPOSEDLY VERY DANGEROUS. IF YOU MOVE THE SEAT BACK, THEN YOU ARE TOO RECLINED TO DRIVE ATTENTIVELY. ONLINE SEARCHES AND COMPLAINTS TO THE DEALER TELL ME I'M NOT THE ONLY ONE COMPLAINING ABOUT THIS, AND IT IS SUPPOSEDLY THE RESULT OF NHTSA REGULATIONS. THIS IS TERRIBLE IF TRUE.

Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
The headlights are either too bright or aimed poorly that it blinds oncoming traffic, who frequently flash their high beams at me. This occurs without any load in back and without me using the high beams. Can Toyota either adjust the bulbs or place a film on the headlights to prevent blinding oncoming traffic? Thank you!
CONDENSATION BUILDING UP IN PASSENGER SIDE HEADLIGHT. THE CAR HAS ONLY 31,200 MILES. NOT CRACKS VISIBLE FROM OUTSIDE ON HEADLIGHT ASSEMBLY. CONDENSATION DISTORTS THE LIGHT BEAM AND DIMMING THE LIGHT INTENSITY.

SEATBELT ON DRIVERS SIDE DOES NOT RETRACT, GETS CAUGHT IN DOOR WHEN EXITING THE CAR. DEALER WON'T FIX IT. IT'S A SAFETY ISSUE IN THAT THE DRIVER WHEN EXITING HAS TO STOP DEAL WITH EXTENDED SEAT BELT CAUGHT IN DOOR, COULD BE HIT BY ANOTHER CAR IN A PARKING LOT OR THE STREET. IT'S BEEN LIKE THIS FOR MONTHS. VERY ANNOYING.A GOOGLE SEARCH SHOWS THIS IS A COMMON PROBLEM FOR TOYOTA CARS.

Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
My car suddenly stopped in the middle of the road with message "Hybrid system stopped steering power low". Safety concern to this happen on the middle of road during rain or cold.
I bought my 2016 Prius brand new in November of 2016. Over the past 2 years or so my OEM leather like steering wheel wrap started to wrinkle. it is now cracking and starting to peel. it hasn't caused any stealing control issues, it is just ugly an slight distracting on the palm of the hand. I do worry that if might start causing gripping issues on that side of the steering wheel if the wrap becomes loose.
