Mechanics will not acknowledge steering problem because the computer doesnt detect it, but the mechanic will re-align the car every 3 Months and charge a lot of money for realignment. Im tired of this problem. One mechanic finally said that it could be a rack and pinion problem because my steering drops and loses tension when steering left, but why cant the computer detect it? The computer compensates and makes adjustments in the steering of the vehicle. But the mechanical problem of the rack and pinion is still there.""

    Anonymous A., NY (2018 Toyota Sienna L 3.5-L V6)

    "It was causing enough of a problem that the Toyota dealer said the steering could just go out at any time. We bought the car in 2023 and 6 months later we noticed the problem in May we had it fixed."
