Collision Prevention System is dangerous. I was nearly rear ended going 75 mph on the PA Turnpike. I was passing a truck that was in the right hand lane when all of a sudden the brakes automatically engaged hard and I nearly was rear ended by another vehicle that was right behind me. It braked so hard it made the tires squeal. I contacted two dealerships and told them what happened and both told me there haven't been any problems with the system that they were aware of and maybe a software update would help. Neither dealership checked if a update in fact was available. I turned the system off and will never turn it back on because it is so dangerous!

Two things here. One is when using adaptive cruise control; when there is a car in front that is going slower than your speed your car will slow down. But when it goes out of the way the car will just rev up as much as it can and just catch up to speed. My Camry before this had two options of speeding up; one slower than the other so it saves the transmission. Also, my engine would randomly be at higher rpm’s than usual when at park. It would idle higher than go lower than back and forth. I’ve experienced it during cruise control when randomly my engine would be revving up and down; car being a little jerky. I’ve read online that Mazda is known for transmission issues with also their transmission sensors. Something needs to be done ASAP and fix the issue

This feature is only able to be turned off by going through 3 or 4 submenus in settings. This is extremely distracting while driving at highway speeds and poses a safety risk. This change does not persist every time you restart the car like other safety features such as lane keep assist. This leads to needing to then navigate through multiple menus while driving if you forget to turn it off every time you start your vehicle if you prefer not to use this feature.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
