2017~2021 Exploding sunroof...wtf?!

It’d depend on how favorable your Mazda dealer’s report is, and how good his / her mood is at the time when the rep at Mazda North American Operations is facing the case. ;)

Honestly, with only 900 miles and 3 weeks old on your 2021 CX-5 GTR, I’d be surprised if your exploding moonroof doesn’t get covered under warranty unless your dealer found obvious evidence of hitting by the foreign object like this which was happened last night in DFW area:

is there anyone at Mazda Corp I should be contacting in the meantime?

Wow!!! Sorry to hear this. It sure takes the 'shine' off of a new car when something like this happens.

You had the CX towed to the dealership? I personally wouldn't have had it towed but that's just me. I would have taken a ton of pics and then vacuumed up the glass and drove to the dealership myself. Too many bad things can happen during a tow.

They did load it up on a flatbed, right? Did you watch as they did this? What did they hook the winch cable to in the front of the car?

the dealership insisted I get it towed. Probably dumb on my part but I wanted evidence intact. This type of truck came below and they used wheel dollies. I told him 4x it was AWD. The guy didn’t seem like a dumbass.


Wheel Lift

Wheel lift tow trucks also tow the vehicle on two wheels but are equipped with a powerful hydraulic yoke that lifts the vehicle off the ground. This provides better stabilization and less chance that the vehicle being towed will suffer any damage. Wheel doilies will still be needed to use this option on an AWD vehicle, and there is still some danger of collision with ground debris.

It's not the absolute temperature of the glass, but usually uneven temperature changes (non-uniform heating and expansion) within the glass that causse it to shatter. And if there is a significant defect in the glass (non-uniform distribution of tempering), it doesn't take much to shatter them; Anything that causes a rapid temp change to the entire or partial surface. Repeated (even light) vibration can shatter defective tempered glass.

As all tempered glass is under tension and sunroofs tend to be slighting curved towards the sky in deference to the roof shape, so when they shatter, makes sense the natural force drives the shards up, at least in the center.
 
I just really wish I had a picture of it before I closed the door and all the glass fell it was undeniably obvious that it was a defect. It looked like a volcano angled upwards towards the initial hole.

You can always contact Customer Experience Center, Mazda North American Operations and complain the case. At lease MNAO will have more data on exploding moonroof, and may be doing something to make it happening less.

Anybody find it odd that the dealer never heard of an exploding sunroof on the CX-5. They must have just started to sell the Mazda brand last week. SMH
Actually “never heard of such problem” has been a standard answer by the dealer for any car problem when you ask about it. :rolleyes:

True , but just sayin'. It's a brand new car and Mazda will no doubt take care of it, so why don't they just admit that while it's not unknown, it's not a common problem. A little honesty can increase confidence in a dealer. Getting BS'ed from the get go ( and discovering this after first encounter) would make me question any later dealings with them.

That's great to hear. In general, dealerships (not specific to Mazda) have a bad reputation due to so many people having bad experiences with them. Its nice to hear about the good experiences, however rare they may be (y)
