2018 Toyota Corolla acceleration complaints

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 control which was better gas mileage and peace of mind to not speed. The speed does go up 5 miles per hour when this happens. Bottom line is the engineers and their bosses who approved this system are all idiots and should be fired. You would assume you would get better gas mileage when going down hill when the engine would disengage because you would need less power and not more to maintain a certain speed. I was informed by the dealer the cruise control is designed to operate by gearing down, I told him no manufacture is that stupid.he then proved me wrong by showing me the manual proving toyota is that stupid.I would have never purchased this car had I known this feature was designed in this way. Who knows what other systems in this corolla are designed in such a stupid manner. I will certainly never buy another auto from this company.
