Reports Of Sunroofs Randomly Exploding Are Skyrocketing

The last few years have seen a massive uptick.

If you have a car with a sunroof, there is a chance that it could "explode" at any given moment. No, this is not The Onion.

According to a Consumer Reports indepentent investigation, exploding sunroofs are not such an incommon occurrence anymore. Relative to the amount of cars on the road it is an extremely small percentage, but the number of these strange happenings are on the rise.

Per the above image, we're seeing that most of the sunroof shattering is coming from more budget friendly car companies and models. According to the CR investigation, there are a few factors that could be at play here including glass type, actual sunroof size increase, and safety standards that haven't kept pace with the size increases.

"Our investigation has found that, with a few exceptions, automakers are not acknowledging or resolving the issue. It’s also clear that the safety standards and regulatory oversight of sunroofs have not kept pace with those dramatic size and design changes and that more needs to be done to guarantee they are safe. While experts we interviewed don’t necessarily agree on what is causing the explosions of glass, they align on this: The bigger the expanse of glass, the harder to ensure that it won’t shatter."

A local Florida news station looked in to this problem as well.

As I said, and as CR reported innitially, the ods of this happening to you are extremely low. What's even more interesting is that it has been reported in 208 DIFFERENT models of cars since 1995. That, in my honest opinion, just shows that it truly could happen to anyone.

It likely will never happen to you, but it's something to keep in mind as you're driving and make sure you get with your dealer on these risks. Most have no idea what to do when it happens on both the consumer and the dealer side.

  • Mostly it is related with combination of body stiffness and thermal expansion of the roof.

  • Sunroof is nice at summer but it also reduce 5+ cm head room and adds more weight to you car about 100kg.

  • Not leaving recirculation on would allow expansion by heat .I would say the glass expands in the recess quicker than the surrounding metal and blows out .there is vent flaps behind bumpers and things too allow expansion of the air inside if these are not functioning you will have problems shutting the last door exited it will catch the first lach but not the second it was a recall on the mark 3 fiesta when they first came out.I was working for ford at the time

    • The vents you refer to are to prevent a pressure build up and allow air to pass through the interior without the back windows blowing out. Glass roofs are exploding because they are fitted without expansion gaps and swelling means they’re...

    • That's what I'm saying if the sunroof and metal expanded at the same rate no broken sun roof .when you shut a door you push a massive amount of air into the car that's what the vents are for.if your on recirculation mode no air enters the car...

  • Hyundai have recalled and fitted new sun roofs to all velosters. Fault was due to robot gripping it too tight in assembly. Research correctly please,

    • How would a robot gripping it to hard cause them too blow out .sounds like a bit of manufacturer bullshit for we made it wrong .my researcher is being in the motor trade for 30 years and having too fix these defects
