I have 2015 Toyota corolla. it has been in the shop for numerous times for a transmission jerking. the service representative said: they didn't know what it was? . Now, it making all kind of funny noises. They said trade in one year. That didn't happen, also I was suppose to get a better interest rate in one year. That didn't happen and still the car haven't been fixed. I guess today they will say: nothing wrong again. I would take my lawnmower
