2022 Mazda CX-5

I was driving in slow moving traffic with vehicles ahead and behind. The vehicle ahead of me slowed, so I applied brakes and began to slow as well. While I was on the brakes slowing at a normal rate with plenty of distance to the vehicle ahead, my vehicle unexpectedly activated automatic emergency braking. It abruptly applied full brakes and came to a complete stop, even though traffic ahead was still rolling. There was zero chance of collision, with ample following distance, minimal speed differential, and brakes already applied. The audible alert triggered at the same time as the emergency braking, providing no advance warning. The vehicle following me was unable to stop in time and caused a rear-end collision with my vehicle. My vehicle had moderate damage, and the following vehicle had more significant damage with airbag deployment. Collision speed was approximately 5-10mph. There were no injuries.

The contact owns a 2022 Mazda CX-5. The contact stated that while driving approximately 25 mph when another vehicle abruptly stopped causing the contact to need to suddenly stop however, the brake pedal failed. The contact stated that the brake pedal traveled to the floorboard then the emergency braking system began chiming. The vehicle failed to stop causing the contact the crash into the vehicle in front. The air bags did not deploy. There was no police report. There were no injuries reported. The contact had contacted the dealer however the vehicle had not been diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 1,546.

The sunroof exploded while driving 70mph on a rural highway. There were no other cars nearby that could have kicked up a rock nor anything that could have fallen on the sunroof. The window buckled outward, not inward. The glass shattered and flew everywhere endangering the driver, passengers, and the car behind me when the window exploded. There was no warning, just a loud boom when the window gave way. My best guess is that this resulted from temperature fluctuation. I was at about 10,000 ft altitude. It froze overnight. The temperature when the window exploded was about 40 degrees, but the sun was out and strong. There was only about a 2,000 ft change in altitude while driving. I can’t imagine that the car seals well enough for the pressure change due to altitude to cause the window to burst, but that would be my second best guess, though a couple thousand feet shouldn’t have cause that big of a pressure change.
