2011 Toyota Sienna Problems

What owners report

Complaints on this model year cluster around the power sliding doors and the front airbag inflator recalls, followed by reports of oil leaking from the engine oil cooler line and unusual transmission or throttle behavior at low speed. Many door and airbag complaints are filed at moderate to higher mileage, while brake and tire reports tend to come in earlier. Owners also describe premature tire wear at low mileage.

   Body and structure

   Power sliding doors fail, stick, or open while driving

   • 121 complaints (20%)
   • median 77,329 mi at 5.7 yrs old (88 state mileage)
   • 8 mention a crash, fire or injury
   • owner-quoted repair $1,556 (median of 9 quotes)
   • filed 2010–2026

   Owners describe sliding doors that stop partway open with a warning beep, doors that will not close electrically or by hand, doors that open unexpectedly while driving, and doors that will not latch. Several mention broken hinges, cables or motors and repairs done under a customer support program or a recall, with some saying the problem came back afterward. Dealers reportedly replaced hinges, cables, motors and latch actuators, and in some cases told owners the correct part was not yet available. Reported from very low mileage up to about 300,000 miles, with many reports between 70,000 and 160,000 miles; some describe trouble in icy or snowy weather.

   Recall 16V858000

   What to check: Cycle both sliding doors several times, power and manual, and watch for hesitation, beeping, or a door that only opens partway. Ask whether the sliding door remedy under the 16V858000 campaign was performed and whether hinges, cables or motors have been replaced.

   “Sliding door opened as usual, with a van full of 3 children, age 8 and under. Pouring down rain, the door decides to malfunction, and would not close electrically or manually. I had to drive home w/ the door open. The problem has since been ongoing and now we just don't use the door.”

   NHTSA complaint #10816998, filed 2015-12, 64,800 miles

   “Left sliding door won't open electronically or manually. Right sliding door is making a clunking noise when opening electronically. I went to my Toyota dealer and the service manager filed a complaint with regional Toyota in chicago. They told my dealer to drop his price from $3,600. To $2,600. And they paid $1,500. Of it. I had to pay the rest. $1,100. Plus tax. Been back to dealer 4times since for the doors not working properly. I had to pay $244. To replace the left door bearing.

   Transmission and drivetrain

   Sudden revving or lurching at low speed

   • 57 complaints (9%)
   • median 24,500 mi at 2.2 yrs old (44 state mileage)
   • 15 mention a crash, fire or injury
   • owner-quoted repair $4,300 (median of 6 quotes)
   • filed 2010–2025

   Owners describe the engine revving or the van surging forward while braking, at low speed, or when shifting into gear, sometimes with the engine racing before the vehicle moves. Some say the behavior fades once the van warms up, and others note it happening while parking or maneuvering. According to complaints, dealers often could not reproduce the condition or described it as normal. Reported from a few hundred miles to about 130,000 miles, several noting cold weather or the first minutes of driving.

   What to check: Test drive from a cold start and pay attention to idle quality and any surge or rev flare when braking to a stop or shifting between drive and reverse. Ask whether the transmission or throttle behavior has been diagnosed or reprogrammed.

   “I pulled into a relative's gravel driveway which has a very large parking area to the side. I pulled up to about two feet from their grassy area, got into position to back up into a parking space, stopped, and put my 2011 Sienna into reverse, and as soon as I gently touched the excelerator to begin backing up the van sped forward at a high rate of speed crashing into and over an 8 inch railroad tie that had a steelbeam on top that separated the driveway from their yard. …”

   NHTSA complaint #10790549, filed 2015-11, 15,600 miles

   “I was trying to park my van inside a campsite, driving at approx 1.2 MPH when my van took off like a rocket. I couldn't stop the car even by braking. Luckily my van went into a ditch, airbags opened up, van went down the ditch and came up at an angle and stopped. I was badly hurt and passed out for few minutes, taken to a local hospital emergency room. The 16 page report ordered by Toyota thru' a 3rd party clearly showed that the car went from 1.2 MPH to 31.5 MPH, engine RPM went from 800 to 4800 RPM in 4.2 secs. …”

   Tires

   Premature front tire wear

   • 38 complaints (6%)
   • median 25,000 mi at 2.4 yrs old (27 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2011–2024

   Owners report front tires wearing out much sooner than expected, in some cases reaching the cords, even after alignment checks and replacement tires. Some connect the wear to towing and to the tire information label, and one owner says the dealer declined to provide replacement tires. Complaints also describe tires losing air suddenly on the highway. Mostly reported between about 5,000 and 24,000 miles on the affected tires, with some later reports past 100,000 miles.

   Recall 14V273000Recall 11V560000

   What to check: Inspect front tire tread depth and inner and outer edges, and ask about alignment history and towing use. Check the door-jamb tire label and confirm the load information campaign 11V560000 was addressed.

   An excerpt from owner complaints in NHTSA records

   “The tires on my van have excessive wear and need to be replaced after only 20,000 miles. I installed a hitch on the car myself shortly after purchasing the vehicle and used it to tow. I received a safety recall notice from Toyota for my 2011 Sienna awd minivan that reads the tire and loading information placard does not state the correct vehicle capacity weight as the rated load for the combination of cargo and occupants. …”

   Air bags

   Airbag inflator recall and airbag warning light

   Mentioned in 4 of 60 sampled complaints

   Several owners write about the Takata inflator recall, describing delays getting the passenger-side inflator replaced and difficulty getting answers on timing. Others report an airbag warning light that comes on intermittently and goes off after a restart, sometimes together with other warning lights. Complaints also describe water from the air conditioning housing dripping onto the module area, which owners say a dealer described as a reason not to drive the vehicle. Reports range from vehicles under 10,000 miles to over 160,000 miles, with no single mileage pattern.

   Recall 19V741000Recall 19V005000Recall 16V340000

   What to check: Use the VIN to confirm which open airbag inflator campaigns still apply and whether they were completed. Watch for a warning light that flickers, and check for dampness or water stains near the passenger footwell and under the dashboard.

   2 excerpts from owner complaints in NHTSA records

   “The air conditioner housing is leaking water onto safety-critical parts. This housing is made of plastic parts that are glued together. Water is condensed during the cooling cycle, and it then collects at the bottom and exits the vehicle through a rubber hose. The glue holding the housing together has failed. Water is leaking from the housing and running onto the computer module that deploys the airbags. …”

   Engine oil cooler line leaks oil

   Mentioned in 4 of 60 sampled complaints

   Owners report oil loss from the engine oil cooler line, with oil seen across the lower part of the engine, smoke, and in some cases a tow after the vehicle was found leaking. Some describe the line as rubber that hardens and breaks and say a later version uses a different material. Complaints mention a warranty extension for this part rather than a recall, and one owner reports engine noise afterward. Mostly reported between about 75,000 and 170,000 miles, often noticed while parked, idling, or pulling into a lot.

   What to check: Look under the engine for oil residue or drips near the oil cooler lines and check the oil level. Ask whether the oil cooler line has been replaced and whether any extended warranty coverage on that part still applies.

   “While driving I heard a noise coming from the engine. I stopped and park the vehicle, opened the hood an noticed oil all over the bottom part of the engine. (oil leak or seep from the engine oil cooler pipe).I purchased this vehicle from a Toyota dealership in stanford ct. And I was never advised of this issue, nor from Toyota or the dealership itself, even though a communication was sent to all Toyota dealer principals, service managers, parts managers. …”

   NHTSA complaint #11373151, filed 2020-11, 108,250 miles

   “Toyota has a known failure issue with the engine oil cooler hose on this model. With this issue, a defect in the hose causes oil to leak rapidly from the hose. A search of the internet can find many instances of this issue, with catastrophic engine failure resulting in certain cases. Toyota has issued warranty enhancement ze2 to cover this. The warranty term for this item is extended to ten years and 150,000 miles. I experienced this failure last week. It occurred as I was pulling into a car wash. …”

Buying note. Have a pre-purchase inspection focus on the sliding doors, airbag campaign status, and the engine oil cooler line, since those account for most of the reports here. Confirming open recalls were completed and reviewing service records for door and oil line repairs gives the clearest picture of how well a particular van was maintained.
