I was driving, and all of a sudden, I hear a loud pop above my head. I slow down to investigate and notice the sound of the wind coming from above me. I slide back my sunroof door and the entire glass is shattered. This could-??ve been a very dangerous situation as I was driving on the highway and the loud sudden pop without warning could-??ve affected me to lose control of my vehicle. I-??ve read up on this and have seen that this issue has happened to a number of vehicles and some manufacturers have had a large list of complaints.

I was driving between 40-50 MPH at a consistent speed and I began to have to put the brake pedal to the floor in order to slow down the car. Even when doing this the car does not slow down at the rate expected and stopping distance has increased by more than 50 percent. Have been told there is Cracked/leaking bore diameter to the master brake cylinder housing is causing pressure and fluid loss, into other internal parts of the braking system. Not visible externally. Mechanic states that they have encountered this problem with several of this year make and model with this exact issue. The shop was able to top off the brake fluid which slightly improved performance but the issue still remains. Car is at 104K miles.

Water leak in trunk area leading to about a 2-inch puddle of water accumulation inside the trunk at the location of the spare tire area. Issue was noticed on April 16, 2021. The water accumulated on top and at the bottom of the spare tire. The parts of the vehicle are beginning to be negatively affected --mold, etc. There were items stored around the spare tire 'e.g. flat tire repair kit, emergency blanket, etc. That developed mold due to the accumulated water and were thrown away upon inspection. In addition to the spare tire area accumulating several inches of water, the spare the cover (I.e.plastic honeycomb type that sits directly on top of the spare tire) is affected with the evaporation/condensation of the accumulated water. All other parts of the trunk and vehicle are were not wet to the touch. The source of the water is unknown. And it was not a user error type of issue 'the vehicle has been stored with all windows, doors, trunk, and hood closed. Concern is that the accumulation of water will lead to the development of mold inside the vehicle and an unhealthy environment for the driver and passengers occupying the car. Additionally, it will lead to vehicle corrosion since the area where the water accumulates is not intended to be consistently holding water. Attached are several photos showing the affected area. Note that the photos only show the accumulated water that was underneath the spare tire after the water accumulated on top of the spare tire (inner section of the spare tire metal wheel which lays up when stored in the vehicle's trunk), close to 2-inches worth, was removed along with the spare tire itself. I did not think of taking photos of the issue until after I removed the spare tire and the accumulated water. Please look into the matter and consider issuing a recall that would allow Mazda to correct the problem.thank you.

Driving along a highway (left side of road) I crashed into large boulders of concrete scattered along the road that was caused by a previous accident. Traveling at 60 mph my vehicle launched off the ground slamming back down on all four tires. My vehicle then spun out of control crashing to the side guard rail impacting the side of the vehicle 2X's (right side of road) resulting in disabling damage to my vehicle. To my surprise the airbags did not deploy (particularly my side airbags). Later I learned that Mazda (manufacture) reported a recall for my vehicle relating to a potential malfunction of side airbags. Upon my discovery I learned that Mazda had learned of the defect around August 2019, but had not issued a recall notice on their website until January 1st 2020. My accident took place Dec 4th 2019, and I should also add that as of yet Mazda still has not made any direct attempts (email, mail, phone) to notify me of the potential hazard. Had it not been for my own inquiries I still may have not known that there was a safety issue within my vehicle especially when I needed it the most. I don't want to come off as being dramatic but that accident I was involved in could of cost my wife and I our lives. For that reason I am seeking to retrieve the event data records (edr) of my vehicle so that I may determine if the airbags failed to deploy as noted as a potential hazard or if the impact and damages where simply not substantial enough to cause the airbags to deploy. I asked my insurance company if they could assist me in gathering that data which they first claimed to be possible, but shortly after I was informed that they did not have the sophistication to do so, hence forwarding me to this website. Please advise on how I may retrieve that information, any help would be greatly appreciated. Thank you.

Various software control features transiently stop working. The navigation system has failed to come on several times. The key fob stops working and then works again.the problems are always transient and then start working again. The worst thing that happened was the front sensor failed to work and a small pole was hit and did damage to the front fender.

2016 Mazda 6 had a sunroof that exploded on Jan 11, 2017 while driving. It sounded like a gunshot and I almost wrecked. It exploded upward and out of the vehicle although we had a lot of glass that rained back in on us and the inside of her car. The vehicle was only 8 months old. Mazda replaced the sunroof out of "good will" (as they put it) her vehicle is not the first vehicle to do this - google it! they are refusing to repair the leather seats that the glass got embedded in and ripped and are refusing to fix the paint where the glass flew out and took a chunk of paint off the roof and the trunk of the vehicle. We have been trying to work through this with them since January. I have been on the phone with corporate Mazda who in turn have been trying to get passport Mazda on the phone for 2 weeks to get their side of the story. The have not made a connection with corporate in over two weeks. Isn't that like ignoring your boss? besides the fact that Mazda will not stand behind their product and quality one of my daughter first "adult purchases" has not turned out to be a disheartening experience. They have not heard the last from us as we stand up for what is right! do not purchase a Mazda as their customer service is less then satisfactory and we purchased not one but two Mazda's on the same day! --

I have a 2016 Mazda 6 GT with stock 19" dunlop tires. I bought the car with around 80 miles & at the time of the incident was around 6800 miles. I was traveling to work going around 72 mph & the left rear tire blewout causing an accident on the interstate. Tires should not blowout that quickly with proper care of the vehicle. The tire tread wore too fast.

The sunroof in my car exploded and partially shattered while parked in my work's parking lot. Glass was all over the exterior and interior of the car. What glass was left had cracked completely and was unstable. I was able to get the car to my local Mazda dealer and they are replacing it under warranty.
