When driving my 2005 Toyota Sienna van tonight, the Traction Control System engaged suddenly on a slight turn at highway speeds, the ABS System automatically engaged and the van pulled to the right, I had to forcibly muscle the steering wheel to remain on the road, in addition to pulling to the right the ABS braking system suddenly and unexpectedly slowed me down from 55 to 30 mph and the alarm sounded. After stopping to check things out, I proceeded cautiously toward home, the same thing happened 2 more times, so I stopped and turned off the "Traction Control System" button. The same thing happened one more time even with the VSA button off. I got online at home and found that this is quite a common issue that Toyota is aware of. This put me and my family at risk and others at severe risk!This is a critical safety issue! Please tell me how to fix it. Many reports of dealerships ripping people off and not fixing the issue. Should be a simple recall fix.
