Sunroofs can be a great upgrade option for car owners looking to get a little more sunshine on their face and wind in their hair. Most everyone who has had a sunroof make it a must-have requirement for any of their future cars. Sunroofs have come a long way since they first appeared on the market in the mid 20th century. With the advent of panoramic sunroofs, they are not only growing in size but popularity as well.
There are some very rare, but possible downsides to having sunroof though. For instance, a quality issue could mean that a sunroof spontaneous explodes as a car is driving down the road. There have been numerous recalls for these problems from a wide range of manufacturers including Hyundai, Nissan, BMW, Kia and Ford among others. This spread just goes to show that this problem isn’t exclusive to any certain automakers.
The new issue the industry is facing that is not yet (and hopefully won’t be) as widespread as spontaneous sunroof explosion is an issue called sunroof detachment. Sunroof detachments are where the entire glass panel lifts out of the vehicle. Obviously, this can be a major issue if you’re driving down the highway- especially with vehicles behind you. Sunroof detachment is usually caused by a combination of two factors:
Polyurethane is the bonding agent that vehicle manufacturers use to glue the sunroof into place. If the urethane fails, breaking the bond, then the sunroof does not have anything holding it in place.
Once the urethane bond has sufficiently weakened, it won’t take much for the sunroof to detach from the car’s body. A pressure change within the cabin can be enough to launch the windshield into the air. If you’re traveling down the road at 55 miles per an hour and open the windows, the incoming air will create an upward pressure on the inside of a sunroof.
So what happens once the sunroof detaches? Well as you can imagine this could have a wide range of effects depending on the circumstances. If there is traffic behind you, the sunroof could cause serious damage- either striking other vehicles or hitting the ground and scattering debris.
Rest assured that sunroof detachment is a rare issue and it should not deter you from purchasing a vehicle with a sunroof- especially if a sunroof brings more enjoyment to your daily commute.
A handful of makes and models already have recalls for sunroof detachment. They are Mitsubishi, Hyundai, Kia, Land Rover, and Bentley among others. You can use the National Highway Traffic Safety Administration (NHTSA) website to look up whether or not your vehicle has any recalls.
Should your vehicle have an open recall, follow the instructions on the NHTSA site. Most of the time dealerships are responsible for providing parts and labor free of charge to remedy any such manufacturer defects.
