My 2017 Jeep Renegade is at a dealership for the third time. When I am accelerating at around 29 MPH, there is a sudden jerk. It also occurs around 53 MPH. It startles me every time this event occurs. Each time, I pay a deductible and the problem isn’t fixed. Retirement isn’t conducive to $500 repair bills. Can you help? This is definitely a problem with this model and needs to be rectified.
