Lane Departure Warning Question.
 

Hi, I have a 2014 Impala 2LT with 6300 miles on it. I recently took it in for the seat wiring harness recall. When I got the car back the LDW didn't work. So I called the service guy back and asked if anything else was done and told him that the LDW wasn't working and he said nothing else was done to the car. I was wondering iof anyone has any opinions on anything else that could cause it not to work. I was thinking maybe they done a PCM reflash but he keeps telling me no. It was working fine on the way to the dealership. Thanks..

which recall was it

They had to replace/reroute the wiring harness under the drivers seat. The call I got said the wiring harness could possibly get caught up in the seat track and cause a short.
