This problem is very awful. Every mechanic I've taken this vehicle to seems surprised that a 2016 Corolla would have such problem at such an early stage and with less than 100,000 miles on it. They've all said its not worth rebuilding, so I have to replace the damn thing, which is not cheap!!! I don't have another vehicle, so I'm forced to use it as it is, to run errands making the problem worse and having other drivers honking behind me cause I'm causing traffic to slow down. Very annoying!!!
