Catalizador causando bajas emisiones, consecuencia encendido de codigos de luz de advertencia de tablero como luz indicadora de falla (check engine). Luz de advertencia ABS. Luz indicadora de derrape vsc-trac y luz de advertencia de presion de neumaticos. Al viajar por carretera simplemente se apago y sin poder tener control de la misma dicha falla causo que ya no encendiera al tener que solicitar grua para el arrarstre de la unidad hasta la agencia de toyota en cordoba veracruz. Seguro solo intervino con el arrastre de la unidad. Pero la sienna a llevado hasta el dia de hoy y fecha presente todos los servicios de agencia por la cual se llevo de inmediato, pero con la novedad es que ni la misma agencia le a podido quitar la falla. No tienen ni la menor idea de la causa. Su solucion seguen ellos eran los inyectores pero la camioneta volivio a hacer la misma falla y la agencia no da garantia de su mano de obra. Solo aumenta el gasto en refacciones sin solucionar la falla.

Bank 1 sensor 2, ,a/f sensor bank 1 sensor & o2 sensor bank 1 sensor 2, check engine light on along with 2 other lights turn on. It happened in 2017, then went away. The warning lights turn on again in 2020. It costs more than $1000 to fix it. Asked the dealership about this problems. They said it is not normal for this sensor to go bad. We owned several toyota cars so far we do not have any problems. But this sensor issues toyota should recall it to fix the problems

Complaint: toyota sienna 2011 se on 2/3/2016 I took my 2011 sienna to the local toyota dealership because the information display screen indicated vsc system warning and the engine light, trac system light, and warning lights were on. After diagnostics the service advisor explained that fuel emission switch valve was stuck in the off position. The technician report identified the part as p2440 evaporative emission pressure switch valve. The switch regulates the amount of gasoline pumped into the tank through the intake and outtake of air. Vacuum hoses connect the valve to a 'charcoal canister' which collects gas fumes from the tank and routes them to the engine for combustion. Unfortunately, toyota sells these various components in emission system as one unit. The part was $537.92 and $148.88 for labor. The suggested cause was overfilling the gas tank. We have never had a problem filling up tanks (stopping before the point of overflow) with many previously owned toyota trucks and sedans. The core of my grievance is the fact that the owner's manual does not specifically caution the owner that this practice can damage or cause a malfunction of the emission system. The manual only cautions the person pumping fuel 'do not spill fuel during refueling.'(p.150 in refueling section). If this was the real cause for the needed emission part replacement I hope that toyota will write a clear warning about the consequences of "filling up" in their manual or consider redesigning the emission system. Perhaps this complaint will prevent another toyota customer the cost and dissatisfaction of this same experience.

After pulling out of the driveway and driving forward less than 100 yds, the vehicle began to pull left and right as if vehicle stability control were taking over. Very shortly after, the vehicle came to an abrupt stop with brakes seemingly applied on their own (power brake assist?). The screen lit up with the following warnings, "check ABS," "check vsc," and "check brake system," followed by "have your vehicle checked by dealer." the ABS, vsc, emergency brake, and check engine lights on the dash came on as well. Upon taking a look under the hood, we also discovered what appeared to be an oil leak at the head gasket. The vehicle was taken to the dealer and a toyota engineer was flown in to help diagnose the problem. The result was they cleared the codes, wiped up the oil, and said there was nothing wrong with the car. About a day and a half later, the exact same thing happened again with the vehicle pulling, warning lights, etc. This time, the dealership said that they found "hard" codes and that the floor wire harness needed to be replaced. The vehicle has now been out of service for 16 days. We shall see whether the wire harness fixes the problem. The dealer said they put dye in the engine oil to try to detect a leak. Not sure why they didn't investigate the problem while the oil was sitting there. It was very obvious where the leak was.
