I have a 2017 Sienna AWD with a UA80 Transmission and the Check AWD System light appeared. I was able to drive it to Towne Toyota in Ledgewood, NJ and they detected the Sienna having DTC Codes P07407E, P27137F and P27567F. They they recommended a transmission replacement costing $9260.84 before tax that I can't afford right now. I am still able to drive the Sienna but Towne Toyota said that the Transmission will eventually fail. After some research, I discovered there is "ZJC UA80 Warranty_Enhancement" by Toyota. I am troubled that the service folks in Towne Toyota did not make me aware of this program! I am afraid to drive the vehicle knowing that the Check Engine Light may reappear. Or worse, the transmission can completely fail unexpectedly that may prevent me or other vehicles from avoiding a collision. It could also strand me on a busy highway and can possibly put my family at risk.

Loss of power highway speeds, jerky shifting, “sealed” transmission leaking fluid. Check engine light and service required light. I have noticed poor performance with this vehicle before and reported it to the dealer to no avail. Toyota has enacted “customer support program ZJC” but the dealership will not honor.

While driving our vehicle on the highway, the check engine light suddenly came on and traction control turned off. Within moments, the vehicle began to stall and would not accelerate. My wife and children were in the car and we were nearly hit by another vehicle as she struggled to get the car to safety. It was a terrifying experience that put my entire family in danger, along with everyone else on the highway. Upon taking the car to the dealership, we were told the transmission failed and would need to be replaced.

While trying to accelerate on an onramp to the highway, the transmission failed to enter into higher gear, and the check engine light came on. The 2017 Sienna currently sits at 112,951 miles. Leading up to this, we had noticed the van jolting when being put into drive or reverse, and acceleration was often sluggish, with a whirring sound. Inspection by the local Toyota dealership found that the entire transmission needed to be replaced. The serial number of the transmission starts with UA02, which wasn't part of any of the existing 2017 Sienna service bulletins.

On Sunday, [XXX] (at 78,793 miles), our MY17 Sienna XLE AWD suddenly displayed a Malfunction Indicator Lamp (MIL) and a message advising "Check AWD System". The vehicle disabled its cruise control system and AWD system, and no longer displays the Eco indicator when traveling at constant speeds on flat terrain. There was no obvious change to vehicle shifting behavior; the shifting has always been sluggish and occasionally "hangs" at higher RPM before downshifting. There were no symptoms or MILs prior to this incident. We consider AWD to be a safety feature when driving with snow or rain, and we frequently traverse Box Elder Canyon where the summit is nearly 6K feet above sea level. We stopped by an auto parts store (O'Reilly) where they pulled codes from the OBD-II sensor. Their reader showed 3 codes: P2714, P0741, and P2757). The vehicle is currently at Young Toyota in Logan, UT. Young Toyota advised that while the vehicle codes are consistent with bulletin [XXX] , that it is not included by Toyota under their list of affected transmissions. The service agent said a solenoid that governs locking the torque converter was "stuck". Since it is outside the 60K miles/60 month powertrain warranty, Toyota is unwilling to provide goodwill towards a fix. The dealer recommended a "software fix", which may or may not solve the issue, and that a transmission replacement would follow. I am simply in shock that a vehicle we purchased new, have carefully maintained (including through Toyota's maintenance plan for 60K miles), could potentially have a failing transmission below 150K miles. This is the UA80F 8-speed automatic transmission, which I believe was first-equipped on the MY17 Sienna, replacing a reliable 6-speed A/T.

While traveling at a high speed, van's power train jerked hard and rapidly slowed on its own, not allowing me to excelerate. Almost rear ended by following vehicle that managed to swerve around to avoid my rapid deceleration. Check engine light came on and was hard to start. Had to allow the van to sit a while before I was able to start. Van acted like it was in limp mode. This malfunction has occurred several times. Mechanic code shows P0087 fault code. Low fuel pressure. Toyota has recalled many of these vehicles in this year for this issue, but mine seems to not be one of them. Very dangerous.

I was driving on the interstate at approximately 65 miles per hour. My 'check all wheel drive system' warning alarm came on shortly followed by the: check engine, battery alarm, collision breaking system, etc. I'm certain there were more alerts going off; however I was trying to steer a car, that had lost power off the roadway. I was able to get the car safely onto the shoulder where I attempted to turn off the vehicle. I couldn't turn the car off until I realized I needed the car to be in park. After I turned the car off I noticed black smoke coming from the engine and could smell something burning. I opened the door & got my three year old son out of the car & noticed more black smoke. I quickly distanced myself from the vehicle & noticed fire coming from the engine. I called 911 but the car was engulfed in flames within minutes. The fire department responded within 5 minutes & were able to extinguish the fire.
