2006 TOYOTA SIENNA Complaints

The vehicle stability control system randomly engages and activates the brakes without cause. This can happen on a gentle curve going under the speed limit. It is very scary and I am afraid it is going to cause an accident. Internet research shows many owners with this issue and no information on the cause or a fix

Slip light indicator comes on and alarm goes off, while anti-lock brakes engage. This is happening while I'm driving on the highway never in the city. The car starts pulling to the right sometimes almost pulling me off the road. The road conditions are completely normal and dry no gravel in it no reason whatsoever for the anti-lock brakes to start engaging. When this first started happening it only happens on curves while I was driving approximately 35 mph. After a couple of months it started happening also while I was driving approximately 70 miles an hour going straight on a dry road. It almost pulled me off into a ditch. The steering is affected I can barely steer but I have managed to keep the car on the road. This is now happening more frequently. I was almost pulled into another car to my right once. At first it was only every couple of months but now I had it happen twice in about a hundred mile trip. There's no way I can get a mechanic to have this happen because you can't predict when it will happen and many miles it won't happen. It is very very dangerous and I'm afraid to take my Toyota sienna on the highway now. After researching it I have found that many people are having this trouble with their Toyota Sienna's there needs to be a recall or a repair. Apparently Toyota mechanics have replaced all kinds of things in the Sienna's but nothing has fixed the problem.

This is a Braun Side Entry Rampvan Conversion. In 2008 there was a safety bulleting 34238 in which I took the vehicle in for inspection and any corrections. On January 19,2023 the rear axle mount broke off while driving. The vehicle was inspected by my insurance company, who denied my claim saying it was a result of wear and tear. The car fax report states it is a total loss due to flooding, which I am in the process of disputing. The cost to repair is several thousand dollars. Do I have any recourse regarding my vehicle. I had the vehicle serviced at Toyota for some normal mtce December 22 & 14th total cost of $3000.00, and there was no mention from them that there was an issue, which could have caused an accident.

Every time I go around a curve, the ABS TRC and vehicle beeps like I'm sliding. It happens on every curve. Its very dangerous. I have unplugged the sensor under the front passenger seat and all problems go away. i have replaced this part and it still has not fixed the problem. with part unplugged i have no ABS TRC Airbags none of the safety equipment is working while unplugged, but is safer than having my brakes slammed in every curve.

The contact owns a 2006 Toyota Sienna. The contact stated that she heard a strange noise while decelerating and the brake pedal failed to engage. There were no warning lights. The contact continued to depress the brake pedal with force until the antilock braking system engaged but failed. The vehicle was towed to an independent mechanic where the brake pump was replaced but the failure recurred. The contact then had the brake pump replaced for a second time, but the failure recurred. The vehicle was towed to another independent mechanic where it was diagnosed that the ABS needed to be replaced and the contact was advised to take the vehicle to a dealer. The dealer was notified of the failure and informed the contact to take the vehicle back to the independent mechanic. The manufacturer was not notified of the failure. The failure mileage was approximately 90,000.

Vehicle Trac Control/ABS system engages periodically especially on winding roads between speeds of 30-60mph. Trac Control alarm goes off and vehicle pumps brakes automatically, then resolves. This is extremely dangerous especially when roads are wet/icy or when being followed too closely by another vehicle. Tried replacing front right wheel speed sensor but problem persists. Research shows this is a chronic problem with Sienna vans and needs to be repaired or guidance provided by Toyota on how to resolve before someone gets hurt. Please help!

While driving vehicle on dry, non slippery roads with slight to moderate curves, vehicle illuminates Traction Loss light, sounds alarm buzzer, and at times applies brakes and dethrottles engine, even when no loss of traction has occurred. This happens while driving on straight roads with slight unevenness. Had to disconnect wheel speed sensor harness to disable ABS/VSC system. When this happens, the vehicle automatically applies brakes to certain wheels and dethrottles the engine, this can pull the vehicle to one side sharply and can cause an accident.

Airbag warning light intermittently flashes, upon personal research on owner forums this is a common issue that is most commonly fixed by wiggling or disconnecting/reconnecting the airbag sensor wiring below the front seats.

Airbag system warning light due to failing connector under the front passenger seat. Code 44 / B0111. See Toyota T-SB-0069-12. This is a pattern failure in a critical safety system.
