Car recently is not shifting properly. Drives at high rpms and if i accelerate too quickly say i get up to 80 mph on highway car won't shift into next gear the rpms suddenly drop all the way down to under 1000 and quits accelerating until it jumps back into gear. Have to let foot off the gas for it to shift and cruise control has been not functioning properly either.

The 2018 toyota corolla cruise control is dangerous. When cruise control is on, going down a slight hill, the transmission downshifts but throttle does not reduce causing car to increase speed 10-15 mph with high rpms. At bottom of incline transmission goes to higher gear and brakes are applied very hard causing vehicle to suddenly and violently slowdown 15-20 mph. In this situation if cruise control is not…

They asked me to come to toyota of dallas to fill out an "unintended acceleration" ua report (see below). The technician became very angry about this issue and told me that the manufacturer created the car this way.

The rpm of the car jumps upto 4000 when attempting to slow the car on down hills. Toyota dealerships are refusing to acknowledge the issue but there are cases many people got their car fixed or exchanged. This proves the issue when using cruise control. The ideal intent of using the cruise control is to save gas mileage and effort to drive the car for long distances. I have to travel long distances to work on daily…

When using the radar controlled cruise control, the engine will sometimes rev to over 4000 rpm. A toyota field engineer told me that this is engine braking, but this occurs when the car is on a level stretch of highway at the set speed and no other unusual circumstances. This exact same problem occurs with my wife's 2017 corolla. I've read a number of comments on the toyota owners website…

The cruise control system is designed so the engine and transmission down shifts when the system is engaged and going down hills. This puts much more wear and tear on both the engine and transmission. In addition to the down shift the rpm goes to over 4000 in an attempt to slow the car. This is completely unnecessary and drastically reduces gas mileage, which is exactly opposite of the original intent of the cruise…
