2016 TOYOTA PRIUS Recalls, Complaints & Safety

Found coolant leak from heat exchanger into exhaust pipe. Looks like, T-SB-0135-19.

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!

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.

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. 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.

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.

We were driving in San Diego and had driven oven a bit pothole. About 50 miles after driving over the pothole, the brakes stopped working. We were pressing down hard on the brake, but the brake was soft and did not do its job. We almost rear ended the car in front of us. We brought the car right away to a close by auto shop and they said there were no leaks as the brake fluid was still close to the max and they did not find any indication of a brake fluid leak and sent us on our way. We are still unsure as to why the brake from this vehicle stopped.

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.

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.

The contact owns a 2016 Toyota Prius. The contact stated while driving at approximately 70 MPH, the steering wheel stopped operating and the vehicle began to shut down. The contact stated that a yellow blinking light and a hybrid system malfunction warning light illuminated the instrument panel. The vehicle was taken to an independent mechanic where it was diagnosed that the hybrid battery was low and there was a failure of the engine wiring harness. The hybrid battery was able to recharge but the dealer stated that the electric wiring harness needed to be replaced. The vehicle was not repaired. A dealer was not contacted. The manufacturer was made aware of the failure. The failure mileage was approximately 159,141.

Coolant is leaking. There were no indicator that coolant is low. Suddenly while trying to get on the freeway the car would not get up to speed regardless how much pressure was put on the pedals. On the way back home, all of a sudden the engine temperature light flashed on then off twice. The car operated like normal but it was still concerning and we had it checked out. Coolant was leaking but no where to be found? It seems Toyota had previous recalls where coolant was leaking into the engine. I think my model is also affected.

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.

We were driving kids to camp and the thermometer light went on. It was blinking for a while, then turned off and then turned steadily on. We weren't sure what to do, so we called our trusty mechanic who said "bring it in right now." We did and it turned out that this was a broken head gasket. Our car is regularly maintained by a trusted Prius mechanic and has less than 78K miles, despite its age. From our mechanic: We found the engine coolant was low in the radiator. We filled the system and pressure-tested, found no external leaks. The thermostat and fans operate normally. We found 54 ppm HCs in the radiator initially, and after a test-drive we re-checked and found 110 ppm HC in the radiator. Combustion chamber gas is getting into the cooling system, typically a symptom of headgasket failure. The cylinder head needs to be removed to evaluate. FYI this is the first headgasket failure we have seen on the 4th gen Prius, but it is the same engine designation as the 3rd gen Prius, which has a pattern problem of headgasket failure. The expectation is that the failure is the same, but we need to open the engine to evaluate. Given the low mileage, it might be worth pushing Toyota for a goodwill warranty even though it is out of the official powertrain warranty period. I called Toyota and they refused to pass along a goodwill warranty.

The contact owns a 2016 Toyota Prius equipped with Cooper Tires, Tire Line: Mastercraft, Tire Size: 195/65/15, DOT Number: (Not Available). The contacted stated that while driving approximately 65 MPH, the vehicle began to violently shake and vibrated. After stopping to inspect the vehicle, it was discovered that the passenger’s side rear tire had experienced sidewall steel belt separation. The cause of the failure was not determined. The local dealer and manufacturer were not notified of the failure. The failure mileage was approximately 20,000.

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.

Shortly after having my Toyota serviced, I had an engine coolant warning sign appear. I checked and noted the coolant was gone. I bought coolant and filled the coolant tank. A week later, I see the light again. I have seen no leakage at all on the ground. I refilled the coolant and checked again the next morning. Again the tank is empty. I took the car to a local reputable service person and thus far, he sees no leakage outside of the car. This suggests to him a bigger problem, where the coolant is going somewhere it should not. If it is to the engine, I will have to replace that!!

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.

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.

Overheating light began flashing while driving 5/21/22. Drove to Napa Auto Parts and saw coolant reservoir was empty. Bought anti-freeze and filled reservoir. Upon arrival at destination, reservoir was empty again. Filled it again. Upon the next morning, reservoir was empty again. Took it to an auto-shop which found that the exhaust heat exchanger in my car has failed and is leaking coolant. Please see Applicable technical service bulletin, T-SB 0135-19. While the car is less than 96 months old, it is above 80k miles. I see this issue has been escalated in California, where the warranty is for 96 months and 150k miles. Want to report that the change in miles between states is disappointing. This issue is common and should be handled as a known recall, not just a known issue.

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.

Our car has approximately 65K miles on it. THREE of the door lock actuators have failed already. This is terrifying that we might not be able to lock or unlock doors in an emergency particularly with our kids in the back seat. We have had our Prius serviced regularly by an independent well regarded local hybrid car mechanic and they think it is very odd that these have all failed so quickly.

The active grille shutter system failed due to debris. There is a bulletin already that references error code P05A072 - active grille shutter stuck open. The code I got was P059F73 - active shutter grille stuck closed. Not sure why it wasn’t included in the original bulletin when the cause and part are the same. This seems to be a known problem with this vehicle that can lead to engine overheating. Bulletin referenced was T-SB-0319-17.

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.

Over the course of the last year, I have noticed an increasingly louder clicking noise coming from the front left (driver side) wheel area upon breaking. The noise goes away if I shift into neutral, so I'm nearly positive that this is related to the axle/CV joint. I've also conducted extensive research on this issue and it is a common problem encountered by other Gen4 Prius owners. Toyota even issued a TSB for this issue in December of 2018 (T-SB-0157-18), NHTSA No. 10153229. My car had its powertrain warranty lapse earlier this year, but I know for a fact that this has been covered out of warranty because I've corresponded with other Prius owners who had Toyota cover the repair of this defect/glitch. I am trying to avoid a catastrophic breakdown of my CV joint if I'm driving on the highway and I'd appreciate it if NHTSA would be able to compel Toyota to help with the repair of this issue. I've had no luck dealing with either the dealership, or the corporate office at Toyota. They do not seem to be taking any ownership of this issue nor taking demonstrating any accountability.

Moments ago, I entered my 2016 Toyota Prius to find that my windshield had mysteriously cracked while parked over night. The crack was not present when I last drove the car last night. Based on some online research for windshield replacement cost, I've learned that Toyota was faced with a class action lawsuit regarding 2016-17 Toyota Prius containing defective windshields; in which these windshields are known to unexpectedly crack while parked or under ordinary driving conditions. Furthermore, my Toyota Prius is equipped with safety features (such as pre-collision system, lane departure alert with steering assist, automatic high beams and full-speed dynamic radar cruise control) that require a front camera to function properly. The cracked windshield now interferes with the camera's visibility, line of sight and perceived orientation, thus causing me to feel unsafe while driving the vehicle. I am filing this compliant because I am now faced with not only an unsafe vehicle to operate, but also the cost to fix a windshield that is known to be defective from Toyota.

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.

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).”

Crash

Vehicle stalls for 5-10 seconds when stopped at a red light. Seems to happen sporadically and is difficult to reproduce. There have been other reports of it online here: https://priuschat.com/threads/tsb-nimh-only-reduced-power-when-accelerating-from-a-stop.187455/ https://priuschat.com/threads/2017-prius-2-no-acceleration-movement-from-full-stop.209317/ https://priuschat.com/threads/2016-prius-2-stalling.200606/

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.

THIS ISSUE HAPPENS RANDOMLY. WHEN POWERING THE CAR ON, AND WHILE THE CAR IS DOING ITS ROUTINE DASHBOARD LIGHT-UPS AND THE DINGING SOUNDS, SOMETIMES THE FORWARD SONARS WOULD BEEP AND DETECT THE OBJECT IN FRONT OF THE CAR. THE FORWARD WARNING INDICATOR SHOWS UP ON THE MULTI-INFORMATION SCREEN EVEN WHEN THE CAR IS STILL IN PARK AND WHILE THE NORMAL SYSTEM STARTUP IS TAKING PLACE. IT IS NOT SUPPOSE TO DO THAT, AS THE TRANSMISSION IS STILL IN PARK AND RUNNING THE SYSTEM STARTUP TESTS.
