I have a 2023 GMC Yukon that has been to the dealership 3 times in a weeks time, and as of today, 8/31/26 will be the fouth time. On 2 occasions, the SUV has entered limp mode while driving. I had the SUV towed for the first limp mode, and the dealer claimed it needed recalibration modules. I picked up the car and drove home eight miles, and the check engine light came on. I returned the next day for readings and tcm p0700, p1789, u0101, u220f. The dealer's solution was to recalibrate the gateway module this time. I drove the car about 20-ish miles, and at highway speeds on the freeway, I got limp mode again. Off to the dealership, having the SUV towed again. The dealership has claimed the electrionic car codes clear themselves and because of that they can't re-create the codes to find a solution. I am scared to drive my SUV, I do not feel safe in it let alone my children.
