My sunroof spontaneously shattered/exploded during a standstill at a stoplight while waiting to enter a freeway. The glass sunroof panel appeared slightly curved upwards (caused by built up interior pressure?) and the shattered hole is right below my roof crossbar. There is no damage to metal roof surface or crossbar. My interior roof slider was closed when my sunroof shattered as it could have compromised my family's safety. After the incident, I drove my vehicle to the nearest dealership (Capistrano Mazda) but they didn't lift a finger besides taking a couple pics and suggested I call their 800 customer experience center number. Since it was a Saturday, I reached out through Mazda's customer experience email. I didn't hear back from Mazda until 4 days later on [XXX] requesting additional information (address, VIN # & mileage). After providing requested information, I didn't hear back from Mazda until [XXX] suggesting I bring my vehicle back to Capistrano Mazda dealership for a diagnosis. Almost 10 days had passed with no action from Mazda while I still had to commute to/from work dealing with loud incessant cabin noise from shattered sunroof open cavity.

The car was running in parking garage without ignition being turned on. When I entered the car, the motor wouldn't catch at all, and message popped up saying the there was a brake malfunction. All the lights were on, so it did not seem to be a battery problem, but the drive function was dead. Several months ago the car started racing while i was driving and i couldnt get it to stop. I finally, while still driving, turned off the ignition and rolled off the road. After a few minutes, i restarted the engine. it had stopped racing and i drove it to the Mazda dealership. They didnt find anything wrong. So this latest incident, Jan. 3rd, involved an uninitiated running vehicle that was parked, and the brake malfunction console notice that said "brake malfunction". Again, the prior incident involved the same vehicle racing on a roadway and necessitated the turning off the ignition while on a major road and rolling the car onto the shoulder. There is something wrong with this car involving the engine and brakes. Triple A came to tow it to the dealership and utilized an alternator to start it, which enabled them to drive it to the tow truck.

On Sunday May 2nd, the bose sound system speakers started emitting an extremely loud static/whistling that I was unable to turn off. My car was parked in the driveway at my shore house when this occurred. I could not turn it off!!! it was extremely damaging to my ears!! had I been driving when this occurred I don't know what would have happened! I can't even think what would have happened if my dog was in the car!! no one should be subjected to that high pitch noise. Luckily, someone heard and saw what was going on and had to pop the hood and remove a chip or fuse that controls the system. Mazda just sent me a recall letter stating that a loud hissing may occur and the car needs to be brough to the dealer. They are completely downplaying the issue when in fact it could have been a very dangerous situation. Mazda needs to stop downplaying the issue and send a letter that reflects that. I've attached the Mazda recall letter.

I want a lifetime bumper to bumper warranty on this vehicle or full reimbursement toward a 2021 model. See image of letter sent. I should not have to worry about the safety of my vehicle with a new model. It is Mazda experiment, not mine.

Last night, after we returned home, my wife removed a cup from our vehicle's cup holder. Shortly thereafter, an extremely loud sound of static began to be heard, emanating from the car's speaker system. Regardless of what we did the sound would not turn off, and remained ongoing for a period of about an hour. Nothing happened when we turned the speaker volume down, or turned the car on or off. It was not only loud, but also quite scary. We had the car towed to the dealership, but they indicated that they could find nothing wrong. They, however, also let us know that when they contacted Mazda Mazda indicated that other cars have been experiencing similar problems. Luckily this did not occur when we were driving, because it would have been quite distracting and could have led to a crash.
