Owners of 2015-2020 Chevrolet Suburban, 2015-2020 Chevrolet Silverado 1500 and 2018-2020 Chevrolet Tahoe vehicles may notice a detent/click at about three-fourths of the way through accelerator pedal travel, with a feel of increased resistance. The accelerator pedal design was changed for vehicles equipped with an eight-speed and 10-speed transmission.
