So right after installing new rear tires i go to drive off the lot and esp/abs malfunction. Basically traction light turns on flashes a few times and then you get esp/abs in the center. He is saying its sbc unit, im thinking its a speed sensor. Other then the steering getting stiff the car drives perfect. Not sure if the sound is normal or not.

Start the engine and turn the steering wheel full left, full right, full left, full right, center.

I did that and nothing happened.

SBC is covered for 25 years/unlimited mileage have MB dealer check it. Might get lucky if SBC is fine, in their attempt to make a sale they may offer suggestion to resolve.

Without the appropriate scanner tool both you and your mechanic are just guessing.

Gotta just take it in and get it properly scanned at the dealer.

Did you recently get an alignment? If you get a bad alignment your car will turn on traction control and other warning lights. This happened to me several times with dumb *** people at Merchants Tire. The steering angle sensor detects something is wrong. Just a thought!
