I had the front brakes and rotors replaced a few weeks ago. This past weekend all 4 tires were replaced. When driving off the dealer after the tire replacement, I noticed the abs and vsc lights were on. Turned back and took the minivan back to the dealer. Next day service mgr said according to the mechanic, the abs actuator needs to be replaced. This is a $2500 part, plus labor.
