2006 TOYOTA SIENNA Complaints

The contact owns a 2006 Toyota Sienna. The contact stated that while the vehicle was at the dealer for a recall repair, the mechanic discovered large holes in the center of the subframe caused by rust. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 218,000.

The TPMS system failed in the ECM or engine computer. It uses the wheel speed sensors on each hub to measure differences in wheel speed and uses this to infer if any one wheel has low tire pressure. (This vehicle does not have TPMS sensors in the wheels.) However, with this failure, it reports a tire pressure problem even though all 4 tires are inflated properly. This problem persists even after cleaning then replacing wheel speed sensors. The problem appears to be in the ECM or engine computer, which is very difficult and expensive to replace. With this problem, the driver is never able to tell if any tire actually has low pressure because the system always reports that a tire has low pressure. Toyota should be required to fix this issue in all affected vehicles.

While driving, there was a recurrent sound like doors locking and unlocking, several dozen times over a half hour drive at 50 miles per hour. When stopped, the passenger side sliding door opened by itself. Luckily, my dogs were in a kennel or they might have jumped out of the car. I closed it and it opened by itself again. At home, the passenger side sliding door opens when my neighbor presses the button on his key fob to open his non-Toyota pickup truck. It will not open or close when I press the button on my Sienna key fob.

The contact owns a 2006 Toyota Sienna equipped Hercules Tires, Tire Line: Roadtour 855 SPE, Tire Size: 215/65/R16, DOT Number: U96VH260H21. The contact stated while driving 35 MPH during a trip, the steering wheel started shuddering. The vehicle was taken to a tire shop, and the contact was informed that the two front tires had sustained tread belt separation and bulges. The two front tires were replaced. Additionally, the contact stated while driving 65-70 MPH, the TPMS warning light illuminated. The vehicle was taken to the tire shop, and the contact was informed that the rear passenger's side tire had sustained tread belt separation, and the metallic belt was poking through the rubber. The contact requested that the rear tires be replaced as a precautionary measure. The rear tires were replaced. All four tires were replacement tires. The dealer and the manufacturer were not notified of the failure. The vehicle failure mileage was 173,414. The tire failure mileage was approximately 16,022. The VIN was not available.

I am contacting you regarding Toyota Warranty Enhancement Program – ZE6. This concerns sticky and cracking dashboard and glare from this. I had no idea this existed. I own a 2006 and a 2010 sienna. I have not received any mailers from Toyota regarding either Sienna's . My van's dashboards are included in this program. Problem is, I never received notice from Toyota about either dashboard. Is there anything that can be done about this?

The contact owns a 2006 Toyota Sienna. The contact stated that while the vehicle was parked, the liftgate was opened and raised; however, the liftgate failed to remain open and raised as intended. The contact stated that when the liftgate was raised, the liftgate independently fell due to faulty liftgate struts. The vehicle was not diagnosed or repaired by an independent mechanic. The manufacturer was made aware of the failure but provided no assistance. The contact was advised to report the failure to the NHTSA Hotline. The failure mileage was unknown. The VIN was unavailable.

My vehicle steering/control has frozen a few times in the past 18-24 mos. This happens for me in wet conditions at slow speeds while trying to turn, usually to the right. The car also seems to slow on its own and pull to the side at these times. This has also happened while reversing out of a parking spot. I do not recall seeing any lights engage but I am more focused on steering the car safely and exterior factors at these times so I haven't noticed the dashboard. It feels like the power steering fails, and I have no control. Thankfully, I have not been moving at high rates of speed, nor been in a position to go into the lane of on-coming traffic or had someone in a lane near me, and have been able to hold in position or manually turn as much as needed. Steering seems to return once the turn is complete. I have been fearful of hitting someone or being hit from behind each time. My mechanic has been unable to recreate the experience and was unable to suggest a direct answer. I see others have had similar experiences and the same lack of answers from even Toyota. Having come across this website and seeing responses here to this exact problem I have had, I am hoping for more information or a recall soon!

Bought the van used last year. Previous owner said mechanic could not diagnose the issue. On slight curves similar to on-ramps while accelerating the Vehicle stability control (VSC) will engage unexpectedly, sound an alarm and jerk the steering wheel. Some times to the point of pulling the vehicle out of its lane. Road speed is decreased dramatically as it feels as though the ABS is engaging. This has happened to me at least half a dozen times since June 2023. The condition will continue for maybe five or ten seconds until the wheel is straightened and speed reduced. Searching the Internet seems it's a fairly common problem. The fix might be to replace the steering rack or disable the VSC system. It's reported by those experiencing the issue get little to no help from the dealerships which strikes me as quite strange... From what I've read it seems to affect 2004-2009 Siennas

The bushing for the gear shift is broken causing the lever to disconnect from the cord preventing the vehicle from shifting gears. This caused the vehicle to become stuck in reverse. The car was stuck in reverse when attempting to shift to drive, nearly causing my wife to crash into another vehicle. There are multiple videos on YouTube demonstrating this problem, it is a known issue. The vehicle/component has not been manufactured. No warning lamps, messages or other symptoms.

Vehicle traction control system will activate around a curve and break the vehicle while the traction control warning system activates. Breaking around a curve in a wet road situation can be very risky. Numerous other Toyota owners have filed similar complaints.
