2005 Toyota Sienna acceleration problems

Filed Apr 22, 2023 · Acceleration, Brakes · UT

I was driving on a dry road, going 70mph when my car began flashing the abs indicator and it began breaking and controlling my steering taking me into another lane. The car slowed my vehicle suddenly down to 60 mph and then went off like it never happened. I then had control. There was no reason for the car to do this. There was nothing in the road and luckily no one was to close to me or there would have been an accident. I almost over corrected due to the pulling of the steering and the breaking of the vehicle.

shifter broke at 55 mph wouldn't stay in 5 gear, was easily moved to R, N, and flopped around! won't stay in 4 now when used either, or PARK unless held when turning car off. NO warning, shifted down for a hill, speed limit change, and corner in neighborhood as usual, no lights on in car. just happened but upon research, have found many others with this problem online, same veh and same kind of miles.Toyota knows but won't recall their broken plastic piece and no notification to consumer

While reversing out of a parking spot, felt the van "jumped" then accelerated on it's own while in reverse swiped a parked truck, and did a half circle into the drive-through of a parking lot only to stopped when it hit another SUV. I felt I had no control of the van while this was happening.

Continuous issues with traction control system almost daily. Any time vehicle veers towards the right anti-slip indicator light, alarm sounds and ABS system activates. This happens almost daily, on dry roads, going downhill or on a curve, even while switching lanes now. This happens above 20 MPH. Driving becomes stressful and worry-some when alarm begins to sound and dash light come on. Fear of losing control becomes great, fear for your passengers safety as well as other drivers safety becomes real. During the past 3 months there have been 5 separate incidents in which the vehicle has lost acceleration, pulls steering in one direction and sudden break lock occurs. 2 of which took place on the freeway on ramp at a speed of 35mph, 1 driving downhill, slightly towards the right, at a speed if 20mph and the last 2 while switching lanes, 35 MPH. Vehicle began losing power and slowing instead of increasing speed. There are many complaints regarding this issue with many drivers in many areas. Why isn't this being investigated?

While on the road, infrequently as we start hitting continuous curves, the beeping starts with slip control symbol coming on. The brakes engage on their own. It doesn't seem to matter how fast or slow we take the curves. I have no control over the vehicle at that point and it starts braking itself for few seconds. Very dangerous on the curves and especially if someone is behind you.

Takata inflators - when driving in city 30mph or freeway 50-60mph in curvy path, the unti-skid lock turns off even if the road was dry. When it happened frequently and a motorcycle almost slammed from behind, I brought my van to the dealer and it shows no record of the unti-skid lock being on. I insisted to take precautions and they did a zero calibration, changed new tires and realignment but problem persist. I brought it back with the same complaint but they claimed the they never had any other customer with the same problem. I reached online yet there were many others. I hope you can help me on this. The dealer can't figure out this problem and just washed their hands. This happened multiple times already and afraid to drive my van.
