    2013 Toyota Tundra Platinum v8 4 wheel drive with 137,099 miles.

    my 4 Lo lights started flashing, with check engine and Trac off light on. Started a couple of days ago and was running fine. Called and left a message with my mechanic about getting it looked at, then before he could call back it went off. Well on the way home they all came on and right before I got home, the overflow for the antifreeze blew it’s top, then I started getting messages that coolant was hot. I was only about 3 miles from the house, so I rushed home.

    I refilled the coolant and noticed it bubbling as the motor idles up and down.

    Any ideas? Would it be safe to drive to my mechanic which is about 35 miles away.

    Your first issue with the lights can sometimes be from just a dirty/bad wheel speed sensor. For your coolant issue if you have coolant boiling in the expansion tank or similar change your radiator cap. Super easy first step. Just make sure the pressure rating is the same.
