2017 BUICK ENCLAVE Forward Collision Avoidance Warnings Problems

On the SVC list, the traction control will turn off unexpectedly & the check engine light will come on. Recently, when this occured, 01/09/2022, the vehicle would start to jerk & lose power. The vehicle eventually recovered after a few minutes at reduced speed. Speed of vehicle during these occurences was any where from 30 to 45 mph, on good asphalt road, driving at a constant speed. Will return to dealer again on 1/12/2022, car will have approxmitely 25000 on it. ADAS list, foward collision warning would not always work. Lane departure warning would sometimes turn off from a few seconds to several minutes. Dealer unable to reproduce problems, no error reading indicating problem, no bulletins from manufacture related to problems. Was told to keep driving the vehicle until something happens again, then bring it in. ( I guess I am not suppose to drive it out of town.)
