This is the base model s automatic transmission 1. 4 tsi. This vehicle doesn't have a gauge for measuring the temperature. Unable to make a decision promptly if the car starts to heat is a safety problem. The car apparently has a mechanism to lower the rpms if the car starts heating and has a light indicating that something is wrong with the cooling system but it is unacceptable that in 2016 you can't see the engine temerature. I didn't notice this while testing the car before doing the purchase and thought it was a matter of configuration but confirmed this with the manual. This car has 85 miles and when running through a slope in rural area if it decides to down shift theres a bump or a knock in the transmutation as if you were abusing the car and the motor or transmission mounts can't hold its force. It really feels awful when this happens. This should happen smoothly but it doesn't. I understand that it will make its own decision of what is the best gear in order to provide enough torque to manage the slope but this is not normal. This could be a sing of future failure and of course an accident can occur. Would like this two points to be investigated by NHTSA.
