IMMEDIATELY AFTER PURCHASING THIS NEW 2019 TOYOTA SIENNA I BECAME AWARE OF THE VEHICLE HAVING ACCELERATION PROBLEMS WHILE ATTEMPTING TO ACCELERATE GRADUALLY IN A LOW SPEED/LOW TORQUE SETTING. THIS OCCURS AT WHAT COULD BE DESCRIBED AS PARKING LOT SPEEDS, 5 TO 25 MPH, PRIMARILY, ALTHOUGH THE VEHICLE HESITATES AND THEN LURCHES ALSO AT HIGHER SPEEDS WHEN DOWNSHIFTING TO GAIN TORQUE IN A 30-50 MPH RANGE ALSO. THIS HESITATION, BALKING, AND THEN RAPID LURCHING FORWARD AT LOW SPEEDS HAS CAUSED PASSENGERS TO COMMENT ABOUT "WHIPLASH" AND BEING PUSHED BACK INTO THEIR SEATS WHEN THE VEHICLE DOES ENGAGE WITH UNEXPECTED FORWARD MOTION. THIS VEHICLE WAS PURCHASED ON 2-18-2019. AFTER DRIVING THE VEHICLE FOR A REASONABLE AMOUNT OF TIME AND MILES I CONTACTED OUR SALES AGENT WHO SET A SERVICE APPOINTMENT FOR MONDAY FEB 25, 2019. ON 2-25-2019 I DROVE THE VEHICLE TO THE DEALER'S SERVICE DEPT WITH "MILEAGE IN" OF 250 MI. AND "MILEAGE OUT" OF 251. SERVICE INVOICE NUMBER 784852 STATES THAT THE ECU WAS CALIBRATED AND RESET. UPON DRIVING THE VEHICLE IT BECAME OBVIOUS THAT THE PROBLEMS WERE NO DIFFERENT AND PERHAPS WORSE. ON MARCH 1, 2019 I RETURNED THE VEHICLE TO THE DEALER AND TOOK THE SERVICE MANAGER AND A TECH-EXPERT FOR A RIDE. THE TECH ACKNOWLEDGED THE STALL AND LURCH PHENOMENON AND SAID HE "HAS DEALT WITH THIS BEFORE". THE TECH AND THE SERVICE MANAGER TOLD ME THEY WERE OPENING A CASE WITH TOYOTA FOR POSSIBLE INPUT TO RESOLVE THIS PROBLEM. I BELIEVE THIS A SERIOUS POTENTIAL SAFETY ISSUE AS THE FORWARD LURCHING OF THE VEHICLE COULD RESULT IN SERIOUS INJURY AS A RESULT VEHICLE DESIGN AND ENGINEERING. OTHER TOYOTA OWNERS HAVE DISCUSSED THIS PROBLEM VIA INTERNET FORUMS. IT WOULD APPEAR TO AFFECT 2018 & 2019 SIENNAS WITH "THROTTLE BY WIRE" DESIGN AND THEIR 8 SPEED TRANSMISSION.

INTERIOR OF VAN WAS CONSUMED WITH FUEL VAPORS. EXTERIOR FRONT OF VAN ENGINE COMPARTMENT ALSO SMELLS LIKE A FUEL LEAK. PROBLEM TAKEN TO DEALER AND THEY COULD NOT FIND THE SOURCE OF LEAK. VAN WAS RELEASED TO ME IN A UNSAFE CONDITION. INTERMITTENT FUEL SMELL BECAME MORE PROGRESSIVE TO THE POINT THE VAN WAS NOT ABLE TO BE DRIVEN TO TO SAFTEY CONCERN OF FIRE. SECOND TRIP TO DEALER THEY COULD NOT FIND SOURCE OF FUEL LEAK. DESCRIPTION OF PROBLEM. WHEN VAN WAS DRIVEN WITH OR WITHOUT AC FUEL VAPORS WOULD BE NOTICED ON THE EXTERIOR OF THE VAN. THIS PROGRESSED TO THE INTERIOR WHILE DRIVING. I ALSO TESTED THE VAN WITH THE ENGINE ON AND BOTH AC ON/OFF WITH THE VAN IN THE PARKED POSITION AND STILL NOTICE A VERY STRONG ORDER OF FUEL VAPORS. THE VAN IS UNSAFE FOR TRANSPORTATION ON PUBLIC ROADS AND UNSAFE TO DRIVE IN WITH MY FAMILY. THE PROBLEM WAS NOTICED WHEN THE VAN WAS STATIONARY OR IN MOTION ON CITY/HIGHWAYS.

I WAS TOLD THERE IS A RECALL UTA VAN UNDER WARRANTY

5/9/2019

I HAVE A CONCERN THAT THE FRONTAL IMPACT SENSOR ON MY VAN MAY NOT BE WORKING. I BOUGHT THE VAN NEW ABOUT 3 WEEKS AGO. IN THAT TIME I HAVE DRIVEN IT AROUND TOWN, ON THE FREEWAY AND MADE A ROUNDTRIP TO CAL. IN THAT ENTIRE TIME I HAVE NEVER RECEIVED ANY TYPE OF AUDIBLE OR VISUAL ALERT THAT A FRONTAL IMPACT IS ABOUT TO HAPPEN. I HAVE THE SENSITIVITY SET TO VERY HIGH. OVER THE COURSE OF THE LAST FEW WEEKS, I HAVE TRIED TO SAFELY SIMULATE THE CONDITIONS IN WHICH THE FRONTAL IMPACT SHOULD ACTIVATE, BUT I HAVE NOT HEARD ANYTHING OR SEEN ANY TYPE OF VISUAL ALERT. I TOOK IT INTO THE DEALERSHIP TODAY AND WAS TOLD EVERYTHING IS FINE WITH IT. HOWEVER, I STILL BELIEVE THAT IT IS NOT WORKING CORRECTLY, SINCE THE VEHICLE HAS NEVER MADE ANY TYPE OF AUDIBLE OR VISUAL ALERT OR WARNING.

June 17, 2022, driving on San Diego freeway north near Sherman oaks California, the Transmission suddenly loses power, however the engine still running feels like the gearbox out of any actions, luckily it’s downhill, managed sliding to the shoulder stopped, The warning light says” turn off traction control”, and “ check engine “ It was rush hour, it was dangerous, after parked few minutes turn off and turn on the engine shift to drive gear the transmission only shifting to lower gears ( 1 or 2) moving slowly, So I managed get of next exit, and stop for few minutes, the I try starting again and driving low gear home, Next morning I turn on the engine the check engine light still on but transmission acted normal, I drove to the Northridge Toyota dealer, which is 2 miles away from my house, Took them 3 day, to return to me, they said it was a coil issue and luckily they didn’t charge me,

6/30/2022

I was traveling on the Capital Beltway (495) during morning rush-hour in my 2019 Toyota Sienna Minivan. Normal Road Conditions: Stop & Go traffic in the right-most lane around 9:30am on December 14, 2022. All of a sudden and without warning, when attempting to accelerate and keep up with traffic after the vehicle was stopped, I found that I was unable to move forward. (There was no indication that my vehicle was suffering from mechanical failure prior to this incident and no visible alert or alarm was triggered) At that point, I powered down the vehicle after turning on the hazard indicator lights. After re-engaging the ignition, I then tried to move forward, and found the vehicle to be unresponsive. A tractor trailer was directly in back of me and was inching closer as to keep up with the rush-hour traffic. I was immovable at that moment and waived the truck around. After finding a break in traffic, I attempted to move out of the right-most lane, but with the transmission not responding to the Drive function, found that my only course of action was to to engage Reverse and move to the Right shoulder of the highway. I then notified triple A and my vehicle was towed to a local garage for evaluation. Upon initial evaluation is was determined that it was either related to where the shift cable goes in to the transmission, or complete transmission failure. It is highly unusual for a Toyota transmission to fail at 71.000 miles (odometer reading at the time of the incident). I currently have two other Toyota vehicles with odometer reading in excess of 140,000 miles. I am concerned for the safety of my family and myself, as this is the primary vehicle used for transport. A 3 year old car with less than 100,000 miles should not suffer from transmission failure. This is a major safety concern. What if this happened and I was not in stop and go traffic or already in the slow lane, on a major highway?

I PULLED ONTO A HIGHWAY AND REACHING ABOUT 25 MPH THE 2019 SIENNA HESITATED FOR AT LEAST 10 SECONDS AS IF IT WAS NOT GETTING GAS. I PRESSED THE GAS WANTING TO GET OUT OF THE WAY OF TRAFFIC AND IT JUMPED SLIGHTLY BUT WOULD NOT GO. THEN IT KICKED IN WITH A FEW HESITATIONS AND TOOK OFF. ANOTHER 100' OR SO, IT DID IT AGAIN. PRIOR TO THIS I HAD ALREADY BROUGHT IT TO TOYOTA COMPLAINING THAT THERE IS A HESITATION WHEN THE VAN IS NOT WARMED UP YET BETWEEN 20-40 MPH. IT IS ONLY SLIGHT, BUT NOTICEABLE AND FEELS LIKE IT IS NOT GETTING GAS. THE VAN DOES THIS EVERY TIME AFTER IT HAS BEEN SITTING LONG ENOUGH TO COOL DOWN. THE LONG HESITATION ONLY HAPPENED TWICE SO FAR (DANGEROUS ENOUGH!), THERE HAVE BEEN A FEW SHORTER ONES, AND THEN THERE IS THE EVERY TIME SLIGHT HESITATION. TOYOTA HAS TOLD ME NOTHING SHOWS IN THEIR DIAGNOSTICS AND THEY DO NOT KNOW WHAT IS WRONG. THEY TRIED CUTTING THE POWER TO THE COMPUTER TO RESET THE MEMORY, BUT THIS DID NOT CHANGE ANYTHING.

11/8/2019

PULLED OUT INTO ONCOMING TRAFFIC AND VEHICLE HESITATED AND WOULD NOT ACCELERATE. DASH LIGHTS CAME ON AND CAR STALLED. ATTEMPTED TO CRANK VAN AND IT RESTARTED BUT WOULD BARELY MOVE WITH THE ACCELERATOR PRESSED FULLY. HAD TO CALL A TOW TRUCK TO HAVE IT DELIVERED TO THE DEALER. I CALLED TOYOTA ROAD SIDE ASSISTANCE NUMBER AND 2.5 LATER NO ONE SHOWED UP. CALLED AGAIN AND DEMANDED A DIFFERENT TOW COMPANY RESPOND AND 30 MINUTES LATER SOMEONE WAS AT THE SCENE. THIS EPISODE STATED 230 PM AND VAN WAS PICKED UP 637PM.

THE FIRST WEEKS SEEMED LIKE EVERYTHING WAS FINE WITH THE VEHICLE UNTIL WE STARTED FEELING LOW LEVELS OF ELECTRICAL SHOCKS. IT WAS MOSTLY ON THE STEERING WHEEL SO WE THOUGHT THAT THE SENSATION WOULD GO AWAY, BUT IT ACTUALLY STARTED GOING WORSE TO THE POINT THAT WE STARTED HAVING DISCOMFORT ON THE SEATBELT AND THE LAST THREE WEEKS BEFORE WE DROPPED THE VEHICLE AT THE DEALERSHIP THE HAZARD STARTED TO INTENSIFY AND GET STRONGER. THE SEATBELT OF THE 2019 TOYOTA SIENNA HAD PROVIDED A LOT OF PAIN TO MY OVARIES (TO THE POINT THAT MY PERIOD HAD BEEN ALTERED DURING THE MONTHS OF OCTOBER TO DECEMBER 2019), IT CAUSED SO MUCH PAIN IN MY STOMACH WHILE BEING A DRIVER AND A PASSENGER SPECIALLY THE LAST THREE WEEKS BEFORE I DROPPED THE VEHICLE AT THE DEALERSHIP. ALSO DUE TO THE FACT THAT I AM FIVE FEET TALL, THE SEATBELT RESTED ON MY NECK WHICH WAS THE MOST UNCOMFORTABLE EXPERIENCE. IN THOSE PAST THREE WEEKS PRIOR TO DROPPING IT AT THE DEALERSHIP, I EVEN FELT SHOCKS FROM THE SEATBELT WHILE IT WAS RESTING ON MY NECK CAUSING NUMBNESS IN MY LEGS. ON REGARDS OF THE STEERING WHEEL, I FELT ELECTRICAL SHOCKS THAT CAUSED TINGLING IN MY HANDS GOING ALL THE WAY UP TO MY ELBOW CAUSING PAIN ON MY ELBOWS (HAVING GREATER DISCOMFORT ON MY LEFT ARM AS I TENDED TO DRIVE MOST WITH MY LEFT HAND) AND MAKING MY ARMS FEEL TINGLING AND EVENTUALLY NUMBNESS.

AS SOON AS I GOT HOME AFTER PURCHASING MY 2019 TOYOTA SIENNA SE, I NOTICED THE POPPING NOISE COMING FROM BOTH FRONT DOOR HINGES.

I own a 2019 Toyota Sienna with 52,200 kms. I bought it January 29, 2021. On Saturday, June 26, 2021, I was exiting the Quebec to Lévis ferry on the Lévis side. As I went up the metal ramp at 10-12 km/hr, ALL the airbags suddenly deployed with a great boom. We hit nothing. ALL The front and side airbags deployed. The front windshield was broken and one of the side windows was totally shattered. In fact it was not there any more. Pieces of broken glass flew all over the car and hit us. The vehicle filled up with smoke. On board was my wife and I and our two special needs sons. We had to hurriedly get them unstrapped and hand them to ferry workers on the outside. I was the only one injured. I received the airbag straight in my face and it hurt my neck. I have had a headache and neck ache ever since (today is June 29). I ignore the reason for which the airbags deployed. But I do know that Toyota has had to recall other 2019 Siennas for spontaneous deployment of their airbags. Maybe it is an airbag defect. My vehicle was still under warranty. The fire department and police were on the scene. The Levis Ferry director wrote a report. The Levis police report is LVS-210626-008. Thank you.

The headlight on the passenger side has LED daylight running lights. A number of the led's are not working of flickering. Toyota refuse to cover this under warranty even though the car was bought 8-31-2019. Not having working daytime headlights is a major safety issue to me.

The contact owns a 2019 Toyota Sienna. The contact stated that the front end of the vehicle would lunge downward towards the road surface when depressing the brake pedal. Additionally, the contact stated while reversing in a parking lot of the Doctor's offices, the vehicle accelerated at high speed independently.

The air bags failed to deploy. An unknown warning light illuminated. The contact sustained bruises on the left arm but did not seek medical assistance. The other occupied vehicle had three passengers including a baby asleep in a car seat located in the rear seats. The contact was unsure whether the other three passengers sustained injuries. The police arrived at the scene but there was no police report filed. The vehicle was towed to the dealer. The dealer informed the contact that they could not diagnose or repair the vehicle as it was involved in an accident that may have injured other individuals. The manufacturer was notified of the failure and informed the contact that a field engineer would contact him for the vehicle inspection. The contact stated the manufacturer took possession of the vehicle EDR but has not informed him of a diagnostic. A case was opened.

The contact owns a 2019 Toyota Sienna. The contact stated that after he entered the vehicle, he depressed the brake pedal to start the vehicle. After the vehicle was started, he shifted into reverse(R) while the brake pedal remained depressed; however, the vehicle inadvertently accelerated without warning. In a desperate attempt to stop the vehicle from crashing into another vehicle, the contact shifted into drive(D) while the brake pedal remained depressed. The contact then stated that he applied pressure to the brake pedal to stop the vehicle from accelerating when the vehicle then jumped the curb and struck a garbage can. The contact then shifted into reverse(R) while the vehicle continued to accelerate to move away from the garbage can and then shifted in neutral(N). The contact then shifted back into park(P). The contact then stated that after he placed the vehicle in park, the inadvertent acceleration stopped. The contact shifted into drive(D) and the vehicle performed as designed; however, the contact was concerned for his safety and carefully drove the vehicle to his residence where the vehicle remained. The contact was unsure if any warning lights were illuminated. The vehicle was not diagnosed or repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 45,750.

This tire separated at the side wall nearest the rim. The last one separated and swelled roughly the size of a ping pong ball, prior to that the same thing. This is the 3rd Pirelli Scorpion Verde All Season tire to fail. After this last one, I realized it's got to be something with the construction of the tire so I googled and found recalls for other Pireeli tire models. I contacted the mfr and they refused to assist. Spoke with very rude individual at Pirelli USA in Rome, GA location who stated 'if I am concerned about the safety of the tire, report it to the NHTSA' and that in order to obtain a replacement I would have to contact the retailer to initiate a return. As instructed, I spoke with the retailer Simple Tire (Trevose, PA), an individual named Shailesh. I was told since there is no NHTSA recall therefore there is no replacement.

The Harness Adjuster Strap (item 5 in attached snip from user manual) loosens while in use. This item was manufactured post-recall 24C002000, using Nuna's new design described here: [XXX] This design change did not prevent the functionality of the strap to fail. There was zero to minimal debris (no food, drink, or water) in the mechanism causing it to fail. The Harness Release button (item 4 in snip from user manual) actuates freely. The adjuster strap, and subsequently the entire harness strap, moves freely, while the carseat is loaded or unloaded. I have a video available showing that the strop in the seat freely moving. We discovered the product failure while loading the child in the carseat and testing it's security by pulling on chest straps. Nuna's response was lackluster and unprofessional. Here is the sequence of events: We immediately reported the issue the first business day available, May 27th, and Nuna responded 24hrs later, informing us they would again respond in 1-2 business days to send us a form and shipping label to send back the defective product. We responded the same day asking them to expedite the process and send us a new product immediately as we had no backup for a carseat and my wife could not leave the home. A little over 48 hrs later they denied our request, and sent us the shipping and RMA form. We are now a full business week past the initial request and now are returning the carseat, with no assurance of when the replacement will be delivered.
