I took my 2016 CRV for maintenance, they did a tire rotation, checked tire pressure, changed oil. Yet, shortly after leaving, an on the highway, I noticed the warning message to check tire pressure. i did not have that message before taking the car in for oil change and regular maintenance, they charged me for supposedly checking the tire pressure! Now, I have the inconvenience of having to take the car in again. Poor quality control is all I can say..
