The glass sunroof spontaneously exploded while we were driving 65mph in lane on a straight section of i-476 between allentown and quakertown pa at 11am on december 31, 2019, constant 40 temp, no recent change in altitude, not near an overpass or close to other traffic. no indication that anything struck the vehicle from any direction. sounded like a shotgun blast. my wife and i were showered with broken glass.terrifying and extremely dangerous, but we were able to exit the highway safely. subsequently read the 2017consumer reports article on such events - turns out this is a thing. insurance covered repair, we were out only the deductible. repair took three weeks. we can provide documents if you like.

There are reports online that mazda3 2014-2016 has a defective infotainment system. screen blacks out and plays one radio station or touchscreen malfunctions. all mazda dealers in houston do not speak of fixing this for free . but throughout mazda forums across the u.s. some people have this equipment replaced for free as mazda knows this is a problem on such vehicle models and years.

The infotainment screen has spider cracks in 2 corners that are starting from the sealed inside of screen. it is spreading and according to the internet blogs happening to other mazda's. see attached photos. the screen has not been damaged and most of the changes happen when i use the command knob and not touching the screen.

The cable controlling the air blower from cold to warm will disconnect. this has happened at stationary and in motion. the bracket controlling connecting the arm moving the blower has broken.

Tcs malfunction. 'transmission control system' symbol is car with skid mark on the bottom. take to dealer right away.

The infotainment center on the dash repeatedly glitches out, will start randomly calling contacts if bluetooth is synced will randomly switch to radio stations, pandora, info on the screen, using the steering wheel controls and center console controls will not do anything. it happens at random times stationary or at any speed, you can't turn it off because the controls don't work, resetting it doesn't work, disconnecting the battery doesn't work it just starts up again as soon as the car turns on, it's an intermittent issue so it may not happen all the time but lingers for days or weeks at a time when it does glitch out.

I was driving down the freeway in the snow/rain mix when i heard a loud bang! i though i was hit by another car but when i looked around i noticed the glass of my sunroof had shattered and some glass fell on me. upon further investigation, the sunroof had actually blew out and upwards from the inside out. i contacted the dealership who then submitted a claim to mazda. although they are aware of latent defects in sunroofs, they refuse to repair/replace mine. it's cold and raining here and i have part of my car roof missing due to a manufacturers defect that i keep reading about all over the internet. this is dangerous to have happen and these sunroofs should be replaced. i could have been killed driving down the freeway thinking i was either hit or shot at! i have images upon request as they are not loaded on this computer.

Sunroof glass shattered in very cold weather. glass actually exploded. vehicle stationary at stoplight on city street

I have 2 issues. the most dangerous one is the entertainment system. it jumps around from phone to radio to contacts to music and randomly makes calls, plays the radio, and cannot be controlled. it is very dangerous as it is distracting to driver. when it make calls it cannot be disconnected and whichever screen is displayed it acts as if someone is constantly making contact with the system. radio stations change and phone calls are made the second problem is that half of the screen is cracked making it impossible to see anything on it. both of these problems have been recognized by mazda but did not repair it when i took it in. they want to change the screen but i'm not sure that is the problem with the uncontrolled system. this happens when the temperature is warm outside. i have read many of the exact same complaints for both of these issues. these issues are mostly when i am stopped but continues when i am moving. since mazda does recognize these problems and have directions for correcting them, they still want me to pay for a new screen and system

Tread separation on two factory-mounted original equipment yokohama tires within 3 weeks at highway speeds, one incident causing significant body damage. incidents occurred at approximately 19,000 miles.

The headrests jut forward at an extreme angle and causing chronic and acute neck, head and back pain. the design of these is a result compliance with the nhtsa's headrest standard. the nhtsa went too far and should reconsider the standard. it is causing misery for thousands or even millions of motorists. to alleviate the pain, i was forced to reverse the headrest...making it far unsafer in the event of an accident. there are thousands of posts about this online.

Car caught of fire on the freeway whole car was consumed started in the front right wheel well area

A few times when starting up the vehicle, the mazda emblem pops up slowly, then fades away, and the lcd system screen will continue to be a blank, black screen with no response until i restart the car. about 7-10 times it has happened where i'm driving and all of a sudden the music will stop, then the lcd screen shows a mazda emblem, and the system reboots itself. i'm taken notes and have tried to find commonalities when this happens, but have not yet. i've mentioned it each time i get a mazda oil service, but the techs never find anything. i also have video recording of one of the instances where it lasted particularly long.
