I drive a 2001 ML320 and bought it used about six months ago. I had a recall done on it in September which was "supposed" to turn the BAS/ESP indicator light off. Ever since, my car's front right tire will occasionally lock while driving. There is no consistency as to when it will happen, it doesn't matter if I'm going 75 on an interstate or 5 mph in a parking lot. Sometimes this happens after the BAS/ESP light is on. Other times, it just happens with no warning. Any idea what could cause this?
