FUEL/PROPULSION SYSTEM
The van has been periodically hesitating, rough idles, and when parked the rpm revs. On 9/13/22, the van was shaking, hesitating, and would not accelerate. It was undrivable and had to be towed. We took it to Toyota of Irving where they charged us $725 to flush the gas and clean the fuel injection system. Despite this, it is still hard idling and hesitating.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was driving on dry road at approximately 65mph. There was a very slight curve in the road and the ABS system engaged without warning resulting in the van power immediately decreasing and fishtailing. Fortunately there was no one immediately behind or beside me or it would have resulted in a collision. I am afraid to use the vehicle. Used a code reader and there are no stored codes.

TIRES:SIDEWALL
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.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
We got into an accident today, and none of the sliding doors would not slide open. It would not even allow us to pull the doors opens. The vehicles electrical was damaged, but that should not prevent the other doors from opening. This is a very bad situation if someone is needing to evacuate the vehicle. The rear passengers would be trapped. Please address this issue with Toyota asap. People who usually have Vans have big families and small children. This would be a very bad situation if vehicle needed to be evacuated asap. The rear passengers would be stuck.

SERVICE BRAKES, AIR:ANTILOCK:ABS WARNING LIGHT
The contact owns a 2006 Toyota Sienna. The contact stated that she heard a strange noise while decelerating and the brake pedal failed to engage. There were no warning lights. The contact continued to depress the brake pedal with force until the antilock braking system engaged but failed. The vehicle was towed to an independent mechanic where the brake pump was replaced but the failure recurred. The contact then had the brake pump replaced for a second time, but the failure recurred. The vehicle was towed to another independent mechanic where it was diagnosed that the ABS needed to be replaced and the contact was advised to take the vehicle to a dealer. The dealer was notified of the failure and informed the contact to take the vehicle back to the independent mechanic. The manufacturer was not notified of the failure. The failure mileage was approximately 90,000.

SERVICE BRAKES, VEHICLE SPEED CONTROL, STEERING
About a year ago the Vehicle Stability Control warning light along with an audible alarm started coming on intermittently while turning on highways going uphill or downhill in dry weather and with no risk of any tire slipping. At first this only happened at higher speeds 65+mph. Over time, it has occurred more and more frequently and can occur at speeds down to 25 mph. At times, the Anti-lock Braking System is also activated resulting in jerky braking and loss of throttle. When people have been following me too closely, this has almost caused accidents. When these symptoms occur, it is always on a curve (of any degree, even slight curves) and while driving at least 25 mph, and even happens on flat turns now. The weather has always been dry with no risk of tire slippage.

ELECTRICAL SYSTEM, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING, BACK OVER PREVENTION: WARNINGS
Wire harness section which controls the Parking Collision Warning and Rear Cross Traffic Warning is frayed, causing failure. This failure was determined by the dealer to be caused by mud packing into the rear bumper cavity. Dealer wanted over $1,000 to fix. Denied warranty, due to the cause being "an outside influence". There is no way to effectively wash the inside of the bumper without removing the bumper. If I pay for a new wire harness, the issue will re-occur. This poses an elevated risk to my family and any occupants of the vehicle, as key safety features must be disabled.

POWER TRAIN
Anyone: In 2013 I bought a new Toyota Sienna from Fiore Toyota in Hollidaysburg, PA. It was advertised with a lifetime engine and powertrain warranty. I thought that I had made a wise purchased. Fast forward to 2022. In early June I noticed a loud humming from the rear differential area and since I had a family vacation planned with my son’s family I decided to take it in for diagnosis to my local dealer, Colonial Toyota of Indiana, PA. They said that it was the electromagnetic control unit but could not get me in for over a week and that it was not advisable to drive long distance. This resulted in my rented a replacement vehicle – an unanticipated expense. When I returned I took the vehicle into Colonial on July 7th and asked if the part would be covered under the lifetime warranty. They said they would check it out. There were several slow responses between the garage and the warranty company. Requests for additional service records, VIN numbers and what not. Meanwhile I am without a vehicle. Colonial had said that the part should be covered under the contract. Also Colonial’s lifetime warranty was a different company than Fiore’s insurer. Who knew? I had assumed that it was all a Toyota thing. Meanwhile after 8 days of no vehicle and another trip to Colorado approaching, (Granddaughter living alone while her husband is deployed in Poland.), I pulled the trigger and said fix the vehicle as I needed it. My thoughts were that it was a Toyota vehicle, serviced by Toyota “certified” techs at a Toyota garage what else would I need? The day after repairs were initiated, the warranty company says that they will need a 3rd party inspection to verify the defect. Just reinstall the broken part so they can hear it and then reinstall the new part or no coverage. Also this was to take place after I should have been half way across the country. Needless to say I didn’t do it. What good is a warranty that doesn’t trust Toyota techs? Out over $2500

EXTERIOR LIGHTING
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.

VISIBILITY:SUN/MOON ROOF ASSEMBLY
The contact called on behalf of her husband who owns a 2019 Toyota Sienna. The contact stated while her husband was driving approximately 65 MPH, there was an abnormally loud bang heard. The driver became aware that the sunroof glass had shattered and that a part of the glass was missing. The driver continued to his destination. The vehicle was not diagnosed; however, the contact spoke with the local dealer; who informed him that a foreign object probably had struck the sunroof for the glass to shatter. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 30,000.
