    Default ASC light flashed over bumps-Why?

    This morning I noticed my ASC light briefly flashing when I was lightly accelerating over a+ rough textured and bumpy road. I was at low speed. The road appeared dry. In 2.5 years of owning this car, I had never experienced this. Not sure there is a problem just a bit curious. Any thoughts? TIA
    Thanks,

    Default Its normal, the tires were losing traction over the bumps and the asc took over to

    prevent wheelspin...

    Default Thanks-Interesting

    I knew that they ASC light would come on when you lose traction. However, I would not have throught this was a situation to have lost any traction.

    BTW, the current tires have over 30,000 miles and have over 1/ 2tread left and recently rotated. I wonder if they are becoming worn enough to consider replacing before winter.

    Or perhaps the rear struts are becoming worn enough to cause excessive wheel hop?

    Thanks again for the reply.
