In may of 2011 I purchased a Toyota Sienna 8 passenger that has been reclassified in Nov 2011 from 1550 lb cargo and passenger capacity. To 1325 that renders it non compatible, for which I had bought the vehicle for. Therefore it has caused and renders this what was 8 passenger and value to decrease. This is clearly a miss representation of sale,and customers should be compensated or a fix to restore this classification should be issued. I have contacted both Toyota and dealer to my regret no solution for this problem is available but if one were to put 8 passenger and cargo, skip the cargo or luggage 8 x's adults @190= 1520 who would be held accountable????.
Water accumulating in fold-down compartment for third row seats. Standing water noticed under carpet. Dealership unable to replicate leak.
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.
Vehicle was in park on a flat street. I wanted to move the vehicle forward, so I depressed the brake, and began shifting the (automatic) shifter to drive. The gear shift lever never made it to the drive position. As I moved the lever, the car shot backwards, striking a vehicle behind me with tremendous force. I have had the same model car for over 7 years and never had this happen. I cannot figure out how or why the car accelerated (forcefully) in reverse as I was shifting into drive.
2011 Sienna le rear view mirror vibrates while car engine is turned on and when car is in driving vibrate to the point that makes a person dizzy. Spoke to boch Toyota service regarding this safty concern, but we were told that the vibration on the mirror comes with a car design, not a malfunctional part, refuse to replace or attemp to solve the problem.
Purchased a 2011 Toyota Sienna limited on June 25th. Next morning, after the car had been in dry weather and garaged overnight, I pulled it out to find the entire rear storage area by the back door was soaking wet with water standing in puddles and the rear welds corroded. It is apparent the water has been there for some time. After wringing out 4 beach towels, I put an industrial fan on it for 5 hours. It's still wet.
Electrical failure the clock loses time when you turn off engine then when you start engine it will give you warning to check vsc , srs airbag is off , radio is off too. The autimatic lock is not functioning we have to lock doors manually. This is frustrating because we have a brand new car!!!.
We have a 2011 toyata Sienna xle that has acceleration issues. While in cruise control, when the vehicle needs to accelerate to regain speed or up a slope, the engine races to 5000-5500 rpm before speeding up. Also, on some left turns the engine nearly dies. The dealer says the engine racing problem is normal and part of the engineering. Big problem.
Purchased 2011 Sienna le van in October 2010. Almost immediately the power sliding doors intermittently open an inch or less & alarm sounds. You can't open or close door at this point. You have to man-handle it to close. Even turning off the power door with the switch does not help. Took it to the dealer & they said Toyota corp. Knows about it but no idea how to repair. I should just check back at next 5000 miles check. What if door gets stuck open & it's raining. . . . Only option is to shut off the power doors & use manually. I bought this model because of the power sliding doors!.
