I took my 2018 GMC to my dealer in Wallingford CT for an oil change and asked if they could take a look at one sensor (LF) that was not being picked up. They indicated that I need to purchase all four sensors and then turned off the three working sensors so now I have nothing but a continuous tire check light on. Very dissatisfied with customer service and the turning of the three working sensors. Any way to turn them back on?
Much thanks!
