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.

On the third day after leasing this brand new car, I was driving at approximately 20 mph, on a normal city street and slowly pressed my foot on the brake as I approached a red light on a standard city street. No cars were in front of me, thankfully, because as I pressed the brake the car accelerated instead of stopping; the engine and parking warning lights (and several other random lights) illuminated and flashed; and at least three text malfunction warnings appeared in the control panel including scbs malfunction. The car was jerking and accelerating forward throughout even though my foot was on the brake. Mazda's tech said that all the malfunctions I observed appeared on the computer readout, but because they could not replicate the problem after a computer reset, they told me that the car "is running as the manufacturer intended." This is terrifying.
