When they weather is cold, my 2020 CX-9 dashboard displays: "Front Radar Sensor System Malfunction" and "Smart Brake System Malfunction". Yet if I drive my 2020 CX-9 on a warm part of the day those 2 messages do not display. I have an oil change scheduled at a Mazda dealership in a week. I don't want them to fool me into an expensive repair when this is just potentially a GLITCH?? Please give advice or best guesses. Thank you! Steve

Do you predict the dealership can Un glitch me and do whatever is needed without adding to the cost of my oil change and front brakes bill?

There is nothing you can do, honestly. You just have to ignore it. There is nothing wrong with the car. It's the sunlight projecting on the sensor at a specific angle and upsets the system, causes the malfunction message. If the mechanic is honest, he should tell you the same thing. You're not the first one having this malfunction code, he must have had numerous complaints about this issue.
Yet why did it just show up now at 60,000 miles? Same car...same sunshine.
