I drove today, and found the issue happened again at low speed, no matter stop or not before. When I drove at the speed lower than 10 mph, I felt like something pushed the car forward, then pulled it back.
I am not sure whether it likes letting the clutch out a bit to fast. It gave me the feeling like the road is uneven. The car was rolling forward. It lasted for about half minute.
My 2018 mazda cx5, about 1000 miles. When I stop and then press the gas , I felt jerky and stuttering at the low speed sometimes. Is it normal or something wrong with the transmission?
