Asked by liortaxil May 04, 2020 at 08:07 PM about the 2011 Buick LaCrosse

Question type: Maintenance & Repair

Hi, I have a Buick La Crosse
2011, Engine 2.4.  An abs
lamp is on, sometimes off,
sometimes on again.  I was
in a Buick garage in Israel, I
was told that an abs system
had to be replaced, it didn't
seem to me.  What do you
think?

Try cleaning your wheel speed sensors - if the light is coming on occasionally and then going off again, that means that it's getting intermittent erratic readings. Sometimes these wheel speed sensors pick up debris from the road that cause reading to be erratic and all can be resolved by cleaning them up.
