Cruise control suddenly ceased operating and I believe that is disabling the automatic collision avoidance system.

When I drive 100 to 150 fest the front camera blocked warning light come on. The only way to reset is to stop turn of car and restart, only to have it happen again and again. The main thing is when and if I can get into cruise control and I am on a major highway and have the cruise set unannounced the warning comes on and turns off the cruise control. If there is someone close they run up on me. I have had it back to the dealer and have called Mazda, all they said was maybe the sun was setting it off, I guess I can only drive at night. The dealer had the car for over 2 weeks and did not fix it. I have recently discovered that if I keep the cruise control on it will not do it, it is very frustrating and now it is off warranty.

The contact owns a 2018 Mazda CX-5. The contact stated that while driving at various speeds with the cruise control and the auto distance features activated, the vehicle would not accelerate while depressing the accelerator pedal. On several occasions while attempting to accelerate overtake a second vehicle, the speed suddenly decelerated instead. After turning off and restarting the vehicle, the vehicle operated as designed. During the failure, the Automatic Braking and Back Over Prevention camera was displayed. No further information was available. The vehicle was taken to the local dealer who performed a software update and later replaced the throttle body however, the failure recurred. The manufacturer was not yet notified of the failure. The failure mileage was 15,154.

Nist campaign 19v497modifications were made. The vehicle now decelerates up to 6 MPH on hill ingress; on egress the vehicle goes at least 3 MPH over setting. When passing cars on a hill, the car slows down when relying on cruise control to resume driving, thus causing us to step on the gas to hold a safe distance from the passed car. We have lost at least 3 mpg fuel efficiency. We have returned to the dealer and they indicated that the vehicle is operating as expected. This fix is a safety concern.

On two separate occasions in the last month, during key on/startup/initialization, I will get an adaptive cruise control/aeb/lane keeping system failure. This is due to a fault in the camera module. Adaptive cruise control still works above 20 MPH indicating that the failure is in the camera module. Failure is latched for the key cycle and but will recover after a long key cycle. 1st time the failure set, it was very warm out so I believed this was due to an overheat. The second time the failure set the temperature was in a normal range so my hypothesis is wrong. No unusual situation is occurring at startup except the failure. Have not taken to the dealer yet.
