general problems of the 2016 Chevrolet Trax

I brought this car as is bical auto mall. (the dealership), I took the car to get checked out the first time and it had a weak battery and I had to constantly get a boost to drive my car 2 weeks later I was advised to go to a gm dealer because my engine light was on, the mechanic explained something was wrong with the valve and it was a leakage. A few day later my engine light turned on again and I had the same problem but only this time the car started surging and stalling out every time I stopped. I returned to the gm dealer again & the problem is still ongoing.

My car loses power and will not accelerate up hills, in the cold on the freeway in the morning (6:00am pst). Check engine light comes on. It has been to the shop 6 times since Feb. 2019 for the same issue of check engine light comes on, loss of power, emissions-air leaks which cause loss of power. I will have to upload documents at a later date as I do not have them today. Sending car back to Chevrolet dealership for another check engine light, loss of power on the freeway while passing a slow moving truck.
