My truck started throwing ESC, traction, lane assist, limited speed and ... codes after I cleared them a couple times it started with the brake controller and the brakes went out almost completely.
First dealer told me the brake controller need replaced as it was seeping fluid external. When I questioned them they changed it it internal leaking. It would be $3,400 to replace it. No guarantee it would clear all codes. I was having trouble believing it was the controller as the brakes worked perfectly at first.
So I paid the $220 diag. and took my truck to another dealer.
The next dealer came back with the same conclusion, bad brake controller with internal leaking and the repair would be 0.00 and it falls under 7 year 70,000 mile emissions some how.
How could that be ??? I said, "have at it". Truck works like brand new.
