2016 Toyota Prius Complaint Log

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

Car was driving fine one day and then while driving down the interstate I had the Pre collision system malfunction error, Brake light came on, Cruise will not operate, ABS light is on. After much research it seems Prius V has a common issue with brake booster faulting.

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.

Driving on the freeway the car stalled and was unable to accelerate. The issue seems identical to the 2020 recall. 2020-06-23 Recall no. 20V369000 Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2013-2015 Prius and 2014-2017 Prius V vehicles not included in recall 18V-684. Excessive voltage in the Intelligent Power Module (IPM) within the inverter may cause the hybrid system to shut down, causing the vehicle to stall while being driven. I was told by the service center that my car is not on the recall list so they are unable to work it as a recall.

Prinx HiCITY HH2 175/65R15 84H Bought this tire in November 2022. About 15000 miles into it, on Aug 6, 2024, the passenger front tire just busted. After swapping with the spare tire, and upon inspection, there was no nail nor it hit the curb, but the side wall is busted. This is a manufacturing quality issue.

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.

While traveling on NHS CA 99 about 80 miles before taking exit 97, there were pieces of tire debri on the center lane. It couldn’t be spotted and my vehicle drove over it making a big thud sound. It shaked my vehicle and left my family scared. It could have been really dangerous if there was a vehicle right ahead or behind my car. This incident broke the front bumper and caused big dent on my right door. This is a big monetary hole in my pocket. This is big concern and should be immediately addressed to avoid incidents further. Kindly let me know if there is a way to file a claim with NHST

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.

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.

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.

See attached document for complaint

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.

Driving on freeway my prius V started shaking violently from what appeared to be overheating of water pump failure or the coolant invertor pump. I believe this to be a known issue Toyota is aware of when I took my Prius into Camelback Toyota in Phoenix they said they could not recreate the issues. I know this was powertrain failure that could have caused me to crash on the freeway.

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.

The original windshield has a “rippling distortion” where the windshield has ripple/bubble from defective glass or installation mistakes, making seeing traffic signs or streets very hard. I just bought this vehicle and noticed the problem. It created poor road vision, especially at night. Toyota needs to recall and replace all these windshields before it causes more accidents due to poor visibility looking through the glass.

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.

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.

While going 70 MPH, I hid a feral hog. Although the front end of my car crumpled up, and we came to a sudden stop, the air bags did not deploy.

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.

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).”

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/

Airbags failed to deploy upon impact with guardrail. Drivers side front corner hit the guardrail at approx. 45% angle at 50-60mph. The vehicle was inspected by an insurance rep. and was deemed a total loss. The car is available for inspection.

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.

WHILE SLOWING AND PULLING INTO A PARKING SPACE, IN FRONT OF THE DENTIST OFFICE WHERE MY WIFE HAD AN APPOINTMENT, THE VEHICLE SUDDENLY ACCELERATED. IT JUMPED THE CURB, AND SHE STEERED HARD RIGHT TO AVOID THE BUILDING DIRECTLY IN FRONT OH THE PARKING SPACE. SHE SIDESWIPED THE FRONT OF 2 VEHICLES PARKED NEXT TO THE SPACE SHE WAS MOVING INTO, AND THE CAR CONTINUED TOWARD THE STREET. IT HIT THE CURB GOING OUT OF THE PARKING LOT AND THE CAR FINALLY STOPPED. A PERSON CAME TO THE DRIVERS SIDE OF THE CAR AND ASKED MY WIFE IF SHE WAS OK, AND SAID SHE SHOULD TURN THE CAR OFF - WHICH SHE DID.

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.

WHEN PUTTING THE CAR IN PARK AND THEN ENGAGING THE FOOT PARKING BRAKE ON A SLOPE, SUCH AS MY DRIVEWAY, AND THEN TURNING OFF THE CAR, THE CAR ROLLS BACK SIGNIFICANTLY. THEN, WHILE EXITING THE CAR, THE REAR BRAKES MAKE LOUD GRINDING AND CREAKY NOISES AS THE CAR SETTLES DOWNWARDS SLIGHTLY. THEN, WHEN ENTERING THE CAR, THE BRAKES MAKE THE SAME CREAKY AND GRINDING SOUNDS. WHEN HOLDING THE BRAKE PEDAL TO POWER ON THE CAR, THEN DISENGAGING THE FOOT PARKING BRAKE, THEN SHIFTING THE CAR FROM PARK TO REVERSE OR DRIVE, THE CAR JERKS ABRUPTLY AND AT THE SAME TIME MAKES A LOUD AND STUCK DISENGAGEMENT SOUND, AS IF THE CAR WAS BEING HELD ON THE HILL/DRIVEWAY SOLELY BY THE PARKING PAWL. IT SEEMS LIKE THE PARKING BRAKE IS NOT HOLDING THE CAR, AND INSTEAD, THE PARKING PAWL IS.

TL* THE CONTACT OWNS A 2016 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING AT A VERY LOW SPEED A SECOND VEHICLE SUDDENLY CRASHED INTO THE REAR OF THE VEHICLE PUSHING IT INTO THE REAR END OF A THIRD VEHICLE POSITIONED AHEAD. DURING THE INCIDENT THE VEHICLE SUSTAINED SIGNIFICANT DAMAGE TO THE FRONT END AND WAS DESTROYED BUT THE AIR BAGS DID NOT DEPLOY. THE FRONT PASSENGER SUSTAINED NECK AND BACK INJURIES WHICH REQUIRED MEDICAL TREATMENT. A POLICE REPORT WAS TAKEN AT THE SCENE AND THE VEHICLE WAS TOWED AWAY. THE LOCAL DEALER AND MANUFACTURER WERE NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 45,000.

BLUE TOOTH CONNECTION VIA PHONE WILL BE DROPPED AFTER 7-10 SECONDS POST CONNECTION TO THE VEHICLE. AUDIO PLAYER CAN BE CONNECTED SEPARATELY BUT ONCE THE PHONE CONNECTS THE DISPLAY CONSOLE RESETS AS IF THE CAR WAS JUST BEING STARTED. CAR CAN BE STATIONARY NOT MOVING. NO DIFFERENCE

I PREVIOUSLY SENT IN A COMPLAINT BUT THERE HAVE BEEN DEVELOPMENTS AND I NEEDED TO EXPLAIN MORE CLEARLY. OUR TOYOTA HAS LESS THAN 18,000 MILES AND HAS BEEN VERY WELL TAKEN CARE OF. DESPITE THIS, OUR VEHICLE HAS NOT BEEN IN OPERATION SINCE EARLIER THIS MONTH. IT STARTED BY FLASHING WARNING LIGHTS 2 WEEKS AGO AND THEN WOULDN'T START UP. SATURDAY WHEN I OPENED THE DRIVER DOOR TO GET SOMETHING OUT OF THE INOPERABLE VEHICLE, THIS INITIATED A VERY LENGTHY TERRIBLE SOUND COMING FROM UNDER HOOD ON DRIVER'S SIDE. IT SOUNDED LIKE SOMETHING WOULD EXPLODE UNDER THE HOOD. THIS HORRIBLE PROCESS APPEARANTLY DRAINED THE WHOLE BATTERY. IT HAS ABSOLUTELY NO SIGNS OF LIFE NOW. ALL OF THIS HAPPENED WHILE THE VEHICLE WAS STATIONARY.

OUR VEHICLE IS COMPLETELY INOPERABLE. THE BATTERY WORKS BUT THE VEHICLE FLASHES ALL KINDS OF WARNING LIGHTS AND WILL NOT START UP. WE BELIEVE THAT IT MAY BE DUE TO RODENTS AS TOYOTA DEALERSHIP POINTED OUT RODENT ISSUE IN CABIN AIR FILTER LAST TIME WE WENT THERE FOR SOME SAFETY RECALL. IT SEEMS TO BE A HUGE ISSUE WITH PRIUS AND WE WOULD HAVE NEVER BOUGHT ONE HAD TOYOTA BEEN UPFRONT WITH THE RODENT ISSUES THAT THEY HAVE WITH THEIR VEHICLES. ARE THERE ANY RECALLS OR CLASS ACTION SUIT RELATED TO THIS RODENT ISSUE AND THEIR USING SOY BASED WIRING AND FAILING TO CLOSE UP RODENT ACCESS TO CABIN AIR FILTER ETC.? THANK YOU FOR YOUR TIME!

I'VE NOTICED A FEW TIMES WHILE DRIVING THAT MY PRIUS STARTED ACCELERATING WHEN MY FOOT WAS OFF THE PEDAL. IT HASN'T CAUSED AN ACCIDENT OR ANYTHING TOO SCARY YET BUT IT IS DISCONCERTING. I NOTICED OTHERS HAD COMPLAINED ABOUT THIS AND WANTED TO ADD THAT I SEEM TO BE EXPERIENCING THE ISSUE TOO. IT'S POSSIBLE IT'S JUST MY VEHICLE SPECIFICALLY; I'VE NOT HAD TIME TO TAKE IT TO A MECHANIC YET.

SPONTANEOUS ACCELERATION INCIDENT. I WAS SLOWLY PULLING INTO A PARKING SPACE IN A PARKING GARAGE. AS I STRAIGHTENED IT OUT TO COMPLETE THE MANEUVER, THE CAR TOOK OFF ON ITS OWN AND HIT THE WALL OF THE PARKING GARAGE THERE WAS SOME DAMAGE TO THE FRONT END. A SIMILAR INCIDENT OCCURRED ONCE BEFORE WITH NO DAMAGE. TOYOTA HAS HAD RECALLS IN PRIOR YEARS FOR THIS PROBLEM - BROKEN THROTTLE RETURN SWITCH - BUT THEY INSIST THIS ISN'T THE PROBLEM HERE. ESSENTIALLY THEY ARE CLAIMING THIS DIDN'T HAPPEN, THAT WHAT I EXPERIENCED WITH THE CAR JUST TAKING OFF ON ITS OWN DIDN'T HAPPEN. THE CAR ISN'T SAFE TO DRIVE WITHOUT GETTING THIS REPAIRED, BUT THEY CLAIM IT DOESN'T NEED REPAIR. IN THEIR RESPONSE LETTER, TOYOTA SAID, "THE EVENT DATA RECORDER (EDR) RECORDED THAT THERE WAS ACCELERATOR PEDAL APPLICATION AND NO BRAKE APPLICATION LEADING UP TO THE IMPACT." OF COURSE THERE WAS NO BRAKE APPLICATION, THERE WAS NO TIME TO APPLY THE BRAKE! THE CAR TOOK OFF LIKE A BAT OUT OF HELL AND RAMMED INTO THE WALL IN 2-3 SECONDS! THIS IS NOT ONLY A DANGER FOR ME AND MY CAR BUT COULD BE FOR OTHER PRIUS OWNERS AS WELL. I HAVE A YOUTUBE VIDEO ON HOW TO DO THE REPAIR BUT I CAN NOT UPLOAD IT HERE.

2016 PRIUS SITTING IN THE DRIVEWAY DURING A RELATIVELY HOT DAY (~95 F TEMPERATURE), APPEARS TO HAVE A BIG CRACK. I LOOKED IT UP AND APPARENTLY TOYOTA IS UNDERGOING A CLASS ACTION LAWSUIT OVER THE SAME ISSUE. NO OUTSIDE DAMAGE TO THE WINDSHIELD, THE DRIVER SIDE WINDOW WAS DOWN FOR THE REASON OF THE HEAT. SHAME THAT THIS HAPPENED. HOPEFULLY SOMEONE FROM THE AUTHORITY CAN HELP WITH THIS.

I WAS DRIVING UPHILL THEN I HAD TO MADE MAKE A STOP SIGN, CAR WOULDN'T MOVE WHEN ACCELERATING, KEPT PRESSING GAS AND STILL NOT MOVING (IT WAS ON DRIVE MODE) DECIDED TO GET OUT AND LOOK AROUND THE CAR. I HEARD UP NORMAL NOISE COMING OUT OF THE EXHAUST. I TURNED ENGINE OFF FOR SOME MINUTES AND IT MOVED. AFTER FEW MINUTES THERE WAS ANOTHER STOP SIGN. SAME THING HAPPENED BUT CAR WOULDN'T MOVE EVEN AFTER TURNING ENGINE IF FOR MORE THAN 15 MINUTES. I HAD TO LEAVE THE CAR SOMEWHERE IN THAT AREA UNTIL I GET IT TOWED. FOLLOWING DAY I TOOK IT TO TOYOTA SERVICE CENTER, THE GUY TOLD ME I WAS THE SECOND PERSON WHO HAD THIS ISSUE THAT DAY. I THINK TOYOTA SERVICE TECH DIDN'T DO GOOD DIAGNOSES AS THE REPORT SAYS I WAS PRESSING THE GAS PEDAL WHEN THE CAR WAS IN NATURAL MODE NOT DRIVE AND THE NOISE I HEARD FROM EXHAUST WAS A RESULT FROM PRESSING THE GAS WHILE CAR IN NATURAL! THAT DOESN'T MAKE ANY SENSE AND I FEEL THAT WAS AN INSULT TO ME. FIRST I LOOKED AT THE CAR MODE TO MAKE SURE IT'S ON DRIVE MODE, I EVEN CHANGED THE DRIVE MODE TO POWER MODE IN CASE IT NEEDED MORE POWER TO MOVE. SECOND. I WAS OUT OF THE CAR, BEHIND THE CAR , LISTENING TO THE NOISE FROM THE EXHAUST SO I DON'T KNOW WHO WAS PRESSING THE GAS PEDAL IN THE CAR, MAYBE THERE WAS A GHOST PUSHING THE GAS PEDAL.

CAR DOES NOT ACCELERATE FROM A STOP WHEN PRESSING THE GAS PETAL WHILE CAR IS IN DRIVE. THIS SEEMS TO HAPPEN ONLY IN THE SUMMER MONTHS. WHILE PULLING UP TO A RED LIGHT I SLOWED THE CAR TO A STOP. WHEN THE LIGHT TURNED GREEN I LET MY FOOT OFF THE BRAKE, CAR MOTIONED FORWARD A BIT BUT WHEN I PRESSED MY FOOT ON THE GAS PETAL THE ENGINE WOULD REV BUT WOULD NOT ACCELERATE IN ANY WAY. I PUT THE CAR IN REVERSE TO TRY AND GET OUT OF MAIN ROAD TRAFFIC BUT CAR CONTINUED TO HAVE NO POWER. I THEN PUT THE CAR INTO DRIVE, PUT MY FOOT ON THE GAS PETAL AND AGAIN, ENGINE WOULD REV BUT CAR WOULD NOT ACCELERATE. THIS IS VERY DANGEROUS AS THE CAR WILL ROLL FORWARD WHEN TAKING YOUR FOOT OFF THE BRAKE, SO YOU CAN ROLL INTO THE MIDDLE OF A HIGHWAY BEFORE YOU REALIZE THERE IS NO ACCELERATION PUTTING DRIVERS AT GREAT RISK OF BEING T-BONED WHILE ATTEMPTING TO TURN (ESPECIALLY LEFT TURNS). I HAVE TAKEN THE CAR TO TOYOTA TWICE AND SERVICE CAN NOT FIND ANY ISSUES AS NO CODES HAVE SHOWN UP. THE SOFTWARE WAS UPDATED AND ISSUE OCCURRED AGAIN AFTER UPDATE.

2016 TOYOTA PRIUS HAS ISSUES ACCELERATING WHEN PUT IN DRIVE AND FOOT IS ON THE GAS PETAL. CAR ENGINE WILL REV BUT DOES NOT ACCELERATE. I REVERSED, PUT THE CAR IN DRIVE AND WENT ABOUT A TENTH OF A MILE AND STOPPED TO WAIT FOR THE GATE TO OPEN. UPON GATE OPENING I PRESSED THE GAS PETAL AND CAR DID NOT MOVE BUT THE ENGINE REVVED. NO WARNING LIGHTS WERE ON AND CAR WAS IN FACT IN THE DRIVE POSITION. SECOND OCCURRENCE HAPPENED AT A MAJOR INTERSECTION, I WAS WAITING AT A RED LIGHT, LIGHT TURNED GREEN I PRESSED THE GAS AND ENGINE REVVED BUT CAR DID NOT MOVE. TOYOTA HAS BEEN UNABLE TO DIAGNOSE THE ISSUE BECAUSE THE CAR DOESN'T GIVE ANY CODES OR WARNING LIGHTS. THEY HAVE BEEN UNABLE TO REPLICATE THE PROBLEM.

CAR ACCELERATING WITH NOT BEING ABLE TO STOP WHEN APPLYING BRAKE, CAR WAS PUT IN REVERSE AND TOOK OFF WITH ENGINE RACING IN HOME DRIVEWAY.
