    I got a message on my display while driving to work this morning saying that the Antilock Brake System has a malfunction. The ABS light and VSS light also went on. I taking it to the dealer tomorrow morning but was wondering if anyone else has had a similar problem. I bought my car in September and it has less that 4,000 miles on it.

    Thanks,
    Jake

    That looks new and like a first. Please keep us updated with what you learn from the dealer. Thanks! :)

    The lights didn't go on the morning I took it to the dealer. They didn't find any codes from the previous day and everything tested out fine.

    So the same thing happened again and I took my car back to the dealer. The lights and messages were still on when I got there the next day but again they didn't find any codes indicating there was a problem. Now they are telling me that this is what is supposed to happen when the car senses a skid. Does this sound reasonable? Why would the lights and messages stay on? What have other people experienced when either the ABS or VSC system is engaged?

    I know in the snow video somebody posted in another thread, the traction light just came on momentarily when the car sensed lack of traction. The user did not have a full skid, though.

    The issue has been happening on a daily basis lately. I brought the car in for its 5K servicing this morning and was told that they need to replace the brake master cylinder. Hopefully that will resolve the problem.

    Really!!! Sounds a bit excessive to me, but if they're doing it free under warranty.... (n)

    Yes and since they have to order the parts I don't get my car back until Friday. It all makes me feel a little uneasy.

    You have a loaner, right? That is covered under the free ToyotaCare since the expected repair time is overnight or longer.

    So I pick up my car on Friday with the new brake master cylinder and before I can even drive out of the dealer's parking light the ABS and VSC warning lights go back on! I brought it back yesterday and was told that a bracket on the brake pedal is causing the problem and they need to replace it. They have to order it so I won't get my car back until tomorrow.

    From the get go, I thought they were guessing. One more thing and I'll be totally convinced!

    This reminds me of my doctor visits. Go in with a little complaint, they bat me around between multiple specialists. Some of the consultations/visits REALLY bald money grabs, follow up visits to let you know: they're stumped. Nothing really resolved, buty they're all a little richer.

    You either pay through insurance premiums or taxes. The money comes from the same paycheck regardless.
