Hello. My in-laws have a 2016 MKX. They keep getting error messages for the lane departure, adaptive cruise control, self-parking, etc. saying that none of these systems are working. They have had the car to the dealership three times. The first time the dealer said the camera's were dirty. The second time they said it was because they took the car on shorter trips and the battery needed to charge up more to have enough power to run all these electronics. The third time they said that one of the wires for the front sensor was all rusted out and needed to be replaced. However, tonight, all the warning lights came on again. Monday is a holiday here in Ontario and on Wednesday they are leaving for Florida. The dealer hasn't been so great in fixing anything. I took a quick look online and didn't see any TSB's for this issue. Has anybody else experienced anything like this and if so, do you know how the dealer fixed it? Any help would be much appreciated. Thanks.
