Chery Tiggo 7Pro 2024 Distinction

My car is in their workshop now and it is for the 4th time now in less than 2 months for the same problem. The car is losing power, the car is jerking while driving and it is a mission to get it started in the morning. I even went as far as replacing the battery. What frustrates me the most is the fact that i took the car to them in 3 times and was told the car is fixed. the following day i experienced the same problem.
