My husband drove my Sequoia 2 days ago on the ice/snowy road w/no problems. Today I attempted to drive it myself but the VSC light shows off & every time I attempt to change it over to 4HI or back to even 2wd my 4Lo button flashes & beeps continuously until I change it back to 4Lo. My vehicle acts like it doesnt want to go & has a winding sound if my speed gets 30 or over. I have owned this veh for 3 Winters & never had an issue. HELP!
