In owners' own words
I was driving the vehicle down the interstate and it started to slow down. The engine was still running. However, the transmission was slipping and I could not maintain the posted speed limit.
Hello, I own a 2011 sienna le V6. In cold weather, it has a problem when braking where the vehicle lurches forward as it comes to a stop.
Electromagnetic coupler on AWD sienna, it seems like a super common problem that costs ~$2,500 us to fix and starts around the 100,000 mile odometer reading.

Recalls for the 2011 Toyota Sienna: 14
These vehicles had their driver or passenger frontal air bag inflators previously replaced under a prior recall using inflators of the same design. The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling. An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
These vehicles are equipped with air bag inflators assembled as part of the passenger frontal air bag modules, used as original equipment or replacement equipment (such as after a vehicle crash necessitating replacement of the original air bags)… An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
If the power sliding door is unable to be opened when commanded, such as if the door is frozen shut, the door may subsequently open unexpectedly, possibly while the vehicle is moving. If door opens while the vehicle is moving, there would be an increased risk of injury to the vehicle occupants.
The electrical wiring in the seat heaters may be damaged when the seat cushion is compressed. If damaged, the copper strand heating element may short circuit, increasing the risk of a fire.
These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules, and used as original equipment or replacement equipment. An inflator rupture may result in metal fragments striking the vehicle occupants resulting in serious injury or death.
The affected vehicles may experience compression of the seat cushion which may damage the seat heater wiring. Damage to the seat heater wiring could cause the wires to short, increasing the risk of the seat burning and causing personal injury to the occupant.
The affected vehicles have a spare tire carrier assembly mounted under the vehicle whose attachment cable may corrode due to high concentrations of road salt splashing onto the spare tire carrier. If the carrier cable is corroded due to road salt, the spare tire may separate from the vehicle, increasing the risk of a crash.
These vehicles were sold with labels that were outside the allowable one percent of accuracy of actual weight added. An inaccurate label could lead to owners overloading their vehicles and tires. An overloaded vehicle can result in a tire failure which may result in a vehicle crash, personal injury, or property damage.
During modification by SET to include accessories such as leather seat covers, seat heaters or headrest DVD systems, these vehicles may not have had the passenger seat occupant sensing system calibration tested. Without passing the calibration test, the occupant sensing system may not operate as designed. If the front passenger seat occupant sensing system is out of calibration, the front passenger airbags may not deploy or they may deploy inappropriately for the passenger's size and position.
These vehicles do not meet the requirement for displaying the correct vehicle capacity weight as the rated load for the combination of cargo and occupants. Incorrect information on the vehicle placard may lead to tire overloading and possibly cause tire failure increasing the risk of a crash.
There is a possibility that the front a-pillar trim panel retention clip may have been damaged during the installation of the aftermarket accessory. A damaged a-pillar trim panel retention clip may allow the trim panel to come loose and injure an occupant in the event of a crash.
There is a possibility that the front, right, drive shaft may break due to insufficient heat treatment. Should the drive shaft break during vehicle operation, the vehicle will lose power without prior warning. Loss of motive power without warning may increase the risk of a crash.
The brake stop lamp switch is mounted on a small bracket welded on the left side of the service brake pedal support assembly. Due to its proximity to the parking brake pedal, in limited circumstances the stop lamp switch bracket could be damaged by the operator's foot during parking brake application. This could result in brake drag with associated brake noise, vibration, and/or illumination of the brake warning light. Braking effectiveness could be reduced increasing the risk of a crash.
These vehicles were sold without the requisite load carrying capacity modification labels. A driver may overload a vehicle which may increase the risk of a crash.
