Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2010 Toyota Sienna owners, lightly cleaned up (personal details are redacted by NHTSA).
We recently had a full diagnostic check done on our vehicle (199 point at Parkway Automotive in Little Rock, Arkansas) that listed some components in need of repair. The only part involving the electrical system needing repair was our battery which was testing as no longer holding enough charge. We took the vehicle to Sam's Club in North Little Rock, AR within the last 2-3 weeks and had the battery replaced with a new Duracell with 3 year warranty. We drove away with no issues with the vehicle and used it for local driving without issues for those 2-3 weeks. The morning of Thursday, December 29, 2022 we started the car to drive to our church about 2 miles away with our four young children (1, 5, 8, 10). In the short drive, dash lights were flickering and the nav/audio screen system was turning off and restarting. …
Tl* the contact owns a 2010 Toyota Sienna. When the vehicle was started, the air bag warning indicator illuminated and remained illuminated. The contact also stated that the horn and air bag, along with other steering wheel functions, were inoperable. The vehicle was not diagnosed or repaired; however, the contact stated that the spiral cable assembly in the steering wheel was defective and needed to be replaced. The manufacturer was informed of the failure. The contact was informed by the manufacturer that there were no recalls pertaining to the failure; therefore, they would not assist. The approximate failure mileage was 120,000. The VIN was not available.
Our 2010 Toyota Sienna recently had a CEL go on. No codes were found by local repair shop so took the car to Toyota dealer. Dealer gave us error code u0123, u0124, u0126 and said we would have to replace the ABS actuator pump which will cost $3600+. I searched online and many have/had the same problem. Also read that Toyota has already covered a extension warranty for the camry hybrid with the same problem part. One of the code was for the yaw rate sensor which was also part of a recall on some Toyota and Lexus cars.
Tl* the contact owns a 2010 Toyota Sienna. When the cruise control was activated, it would deactivate independently. In addition, the bumper sensor detected objects that were not in front of the vehicle. The vehicle was taken to the dealer, but the failure was unable to be diagnosed. The vehicle was not repaired. The failure mileage was 100,000. Updated 01/27/17 consumer stated problem is the dynamic cruise control. The cruise control shuts off with a red light and audible chime while operating.

The rear passenger sliding door is automatic. The door motor started making a loud noise when attempting to open the door automatically. Suddenly, the cable wire that is inside the vehicle into the door to operate the automatic mechanism snapped and is sticking out of the area below the last rear window of the vehicle and now the door will not open, even upon attempting to open it manually.
The automatic sliding door cable broke, and we are now unable to open the door. Our children can only exit the car from the driver side door. We understand that Toyota is repairing certain model years with this safety issue, under an extended warranty. If the part is defective, why are some owners covered and others paying $2000 for repairs?
Both power doors broke the same way. The cable frayed and was pulled into the door by the motor. The doors would not open at all until serviced, which caused a safety concern! The fix was estimated at $1,500 per door.
My Sienna has a problem with the rear sliding door- an issue that Toyota is aware of already from its other customers who own a Sienna as far back as 2004. When I received an alert notice from Toyota concerning this issue and also the alert for the corrosion of the spare tire carrier cable back in August 2012, I took my Sienna into my Toyota dealer, on aug. 24, 2012, to have both issues fixed . However, I was told that my Toyota extended warranty, which I purchased for any electrical issues that I May encounter, did not cover the sliding door sensor, which I consider is an electrical problem by the manufacturer, and there was no official product recall for the sliding door problem which obligated them to repair it. My problem with the sliding door is very random, and has no pattern of when (no weather connection) or why it occurs. …
Both back sliding door cables snapped. Have been advised the motors siezed causing the cables to snap. Neither door works. Driver's side door can only open 6 inches. This is a safety hazard in event of emergency. My children can not get out of the car and can not operate the one door able to manually open. Fix has been estimated at $1900 per door. Toyota knows this is an issue. They issued a customer warrantee enhancement for it but it has expired. They refuse to reopen it. There has been a recall for this on the 2004-2009 model year and currently a recall for this for 2011-2018 models but not the 2010. There are hundreds of Toyota Sienna's on the road with this issue and it is completely unsafe and totally unacceptable that Toyota refuses to take responsibility for the 2010's and cover the costs to fix the problem.
We have a 2010 Toyota Sienna xle. The problem is with the automatic doors and key fob and back hatch door. The key will unlock and immediately relock all the doors. If you touch the buttons to activate sliding doors they work off and on. The big problem though is the back door - the trunk. It opens and then as you are going into the trunk you don't know it is closing on you. This has now happened at least 12 times. I am concerned if my child is in trunk getting bags. It seems some "eye" must see and the door starts rising again. But I have been hit in the back and head a few times. My concern is what if the sensor does not activate and you are stuck in the door/bumper area? I am taking car to dealership but they claim to have never heard of a problem like this.
