I have the same issue initially with my rear pads. I had that reset and then the front one is showing to be yellow on my navigation screen for "service info". Did the mechanic pull a fast one here? Did they just reset my rears and then trip off the front? Because it was showing green prior to me resetting the rear sensors. They said I have about 1/4 break pad left on the front. Would this set off the brake sensors? ~thanks in advance.
