My car has a front radar used in the safety system for Forward Obstruction Warning (FOW) and Mazda Radar Cruise Control (MRCC) but sometimes the system gives a failure warning. I called Mazda USA and spoke to someone in customer relations who says they have no records of this happening to my model or others.
Last month, I dropped the car off for it's first service and told the service adviser about the failures and showed him photos of the warnings that appeared on the dashboard display.
He did a search and said there's nothing in history of this happening to any other vehicles.

Since they need to put the car to a test drive to try to reproduce the problem, I need to schedule an appointment for them to have the car at lease 2 days and arrange a (free) loaner. While I can make arrangements, I wasn't real sure about them being able to find the trouble. For me it starts while I'm on the highway and it's raining happening about 80% of the time.

I spoke to a friend who used to work at a car dealer and he asked "Did you Google it?"

Pretty simple and I found a few Mazda Tech sites where people post questions and get responses from other car owners. I found EXACTLY what I was looking for. It appears on my model and several others current and dating back a few years. Not a new problem.

At this point, I now have the ammunition I need to get back to the dealer for something that should already know about. Making my point, I'll send the service manager some links that explain the issue, with photos so they can get to the source quickly.

Thanks Google!
