My 2024 AT4 6.2L has been doing this from the day I drove it off the lot. I am at 16,000miles. I will report this issue as a ‘bucking’ upon light acceleration and most noticeable at lower RPMs. GM has replaced the engine at 10,000miles, problem remained, replaced the torque converter, problem remained. I’ve had the service manager take drives with me with laptop plugged in to monitor things. I have turned off all frontal anti collision features and I have gone to the extreme of tapping off my windshield & grill cameras to determine if the anti collision system is to blame, problem remains. It’s going back to the shop for a bad injector when picked up on my last scan.
I will say my dealer has served me well, they are trying to resolve it. It’s an annoying problem because it’s not always there but has increasingly more frequent. Can anyone shed some light on this issue ?
