    2012 Prius 3 with Solar Roof:



    At mile mark 315 from NEW this problem reared its head and Toyota can not fix it.



    When a full lock U Turn is made the steering Wheel violently shakes.



    Tho a not at full lock u turn is executed without issue.



    Things found by the dealers:



    ABS sensors fire at full lock due to one wheel turning faster than the other, as happens in a U Turn, yet they are baffled as to why a NOT a full lock turn does not fire the sensors under the same conditions.



    Other 2012 Prius have been checked and this problem does not occur.



    Add into the problem, once the suspension unloads I.E. lifting the car for inspection, the problem will not return till the car settles to its normal ride height.

    In all my years of PriusChat reading, I don't think I've ever seen this particular issue except in your two posts today, so (unless everybody else has just been keeping it secret), I think you might have a problem so unusual that no one here will have ready answers, and someone will just have to dig in and diagnose it step by step. Sounds like it could be a challenging diagnosis (and at dealer clock rates, expensive). Do you have a Mini VCI?

    Oh, that's dealer software huh..yea, as stated before the car is under warranty and I will not play with it till all avenues have been exhausted.
    Personally I think the issue is with the rack. As there appears to be no adjustment and the hard stop is with in the rack, one can only assume the rack specs are off.
    That said tho, Toyota's are not my thing and it's just a generic guess and I hate assuming.

    Do you have regular size tires on there? Try rotating tires?
    Both ways of turn?

    Wheels are 15" tires are 195 65 15
    Same issue with stock Good Years, Michelin, and Toyo, all are low rolling resistance type.
    Tire pressure checked weekly and rotated per mileage.
    Right or left hard stop u-turn will end violently.

    Factory asked if the fitt was directional, it's not. Hard stop U turn right or left will cause the problem.

    Same car here, 2012 Model Three with solar roof, 64k miles, and I've never experienced this.
    The basic factory 36m/36k warranty has expired. It seems unlikely that this will fit under the 60m/60k powertrain or 8y/100k traction battery warranties. Any extended warranties you purchased are a separate matter.

    body kit purchased because I though it was funny, it's a Prius not a race car. Only rockers installed as the rear defuser and front spoilers must the riveted to the bumper caps and I for one am not willing to do that, but have all parts.

    Only it yours will trade in better than mine, when/if I trade up to a Prime.
    I believe a 2012 is well beyond any lemon law applicability.

    It's never a good idea to go full lock on the steering on any car and hold it there. Once you hit the stop you should back it off a bit.

    idk exactly how lemon laws work. but my general understanding is that if they can't fix it in three ttys, you get a new car. idk what time constraints are involved. 2012 certainly seems old, but if toyota has been working on it since 350 miles, without success, and still trying, it's worth exploring at some point.

    Both cars I have with electric power steering -- Prius and Forester -- take to it vaster better than the old hydraulic systems.

    You are being too easy on them.
    If you don't apply a little pressure, they will just keep screwing around with you.

    Take it back in to the dealer.
    Tell them you don't want it back until it is fixed......and you expect a loaner in the meantime.
    Call the Toyota warranty help line and tell them the same thing.
    Call your local Attorney General and inquire about "lemon laws" in your state.
    Tell both the dealer and Toyota that you are checking into this.

    In many places, they get THREE tries to fix a critical problem like that.
    After the third failure, they owe you a new car.

    Not if they started working on the problem in 2013 it isn't.
    And not if they are not living up to the provisions of the warranty.......extended or not.
