2013 Ford Escape, 67000 miles 1.6 ecoboost. I have replaced both rear wheel speed sensors about a year apart. After the last replacement the hill assist and traction control warning lights will not clear. The last ford dealer said the speed sensor was bad after the 100 dollar scan. Had my local independent mechanic charge the sensor , but the codes will not clear. I received a letter from Ford describing a software update that the ford dealer said was not necessary. Long story short two different Ford garages can’t seem to iron out the issues. Yes I had a independent mechanic put the new sensor on to save money on the labor. One of the Ford dealers told me that the cars are complicated to work on and that is why Ford is stoping production of most cars due to software issues. Any help appreciated.
