I have a 2022 Sierra elevation which i bought last year February. The dash lights up with different Warnings: Service traction control, Service transmission, Washer fluid low Add Fluid, Service 4WD,Service ESC, ABS, Fuel gauge fluctuates from empty to full and then it say "reduce acceleration Drive with Care" and I can't go over 64 miles an hour. I have replaced the BCM, checked battery, checked grounds also had transmission checked. I dealt with the dealership for a year and no help so my independent shop is hunting down the problem. It happens randomly. It can happen for a few days in a row or every 2000 miles. I have noticed a hard gear shift right before it does it. Any help would be appreciated. I love the truck but it is unreliable. Here is a list of the codes: U1611, U1610, U0142, U0418 ,U0131 ,U0073 ,U0447, U0146, U0140, U0073 ,U0102, U0403, U0102, U0151, B1981, U0401 ,U0423, U0566, C2A07, U0100, U0121, P0700, P1789, P00FF
