While driving my 2017 Mazda Cx-5, the smart city brake support (scbs) indicator illuminates on the dash. This has happened multiple times over the past several months, on clear, sunny days and in rain and/or snow; on city streets and highways. The rate of driving speed varies from approx 10 to 65 mph. The indicator stays on for anywhere from 20 seconds or until the vehicle is stopped (upwards of 20 minutes). Service techs at local dealer were able to pull the fault code from the computer, but it was generic and gave no guidance. Mazda initially acknowledged this was a problem and replaced the camera that controls the system (mounted interior of car at windshield), but when problem persisted with the new camera, Mazda said it's "normal" for the lamp illumination to display on the dash under various driving conditions and referenced service alert sa-052/17, which discusses fog, rain, exhaust gas from vehicle in front, etc. Triggering the scbs. According to this service alert, a dirty windshield will also trigger the warning light to illuminate. This is a safety concern because not only is the scbs not functioning properly, when the light illuminates it distracts from the act of driving.

I bought the 2017 Cx-5 brand new about a month ago. Today, I put the car in reverse and expected the rear camera to pop up on my infotainment screen; however, it didn't. so, I turned off the car to try and reset the issue, hoping it was a glitch. I turned off the car and turn it back on again and it still didn't work. I did this consecutively 4 times and it didn't work. It seems like this problem is either a wiring issue or software issue. The car's rear camera is supposed turn on in the infotainment screen when you put the car in reverse. It wasn't until I turned off the car and waited for more than 5 minutes for it to to start working again. I'm very concerned about this because the rear camera is a safety issue and I cannot have it only working sometimes when I put it in reverse. This problem only started today. I'm worried that this inconsistency may continue and given this is a safety concern, I'm hoping NHTSA will launch investigation to see if they is a automaker problem and issue a recall. The 2017 cx-9 models seemed to be having the same issue (from the Mazda forums I've read). The last thing I'll add was the typical introduction process of the infotainment screen seemed to be off when this issue was happening. When I put the car in reverse, the infotainment screen just stayed on the same page. I really hope you guys take this seriously and investigate.
