NHTSA Complaint #11051263 — 2014 CHEVROLET EQUINOX

I PURCHASED A 2014 CHEVROLET EQUINOX IN SEPTEMBER 2015. IT HAD 10 MILES ON IT WHEN I BOUGHT IT RIGHT OFF THE SHOWROOM FLOOR. THE CAR CURRENTLY HAS LESS THAN 1700 MILES ON IT BECAUSE IT'S PARKED IN THE GARAGE 90% OF THE TIME. IN NOVEMBER 2017 I OPENED THE VENT PART OF THE SUN ROOF AND HEARD A LOUD CRACK SOUND. WHEN I TRIED TO CLOSE IT, IT WOULDN'T CLOSE. THE DEALERSHIP STATED THAT IT BROKE BECAUSE THERE WAS DIRT IN IT. IT COST ME $1,000 TO REPLACE THE WHOLE MECHANISM INCLUDING THE WINDOW BECAUSE THEY DON'T MAKE PARTS FOR IT. MY QUESTION TO THE DEALER AND CHEVY WAS 'HOW DOES DIRT GET INTO A SUNROOF THAT IS CLOSED ALL THE TIME? THE RESPONSE HAS BEEN I DON'T KNOW. NO ONE CAN EVEN TELL ME HOW TO MAINTAIN IT SO THIS DOESN'T HAPPEN AGAIN. I BELIEVE THAT IT IS EITHER A DEFECT WITH THE SUN ROOF OR IMPROPER INSTALLATION AT THE FACTORY. THE NEW SUN ROOF IS MADE TO BE MORE HEAVY DUTY BUT I AM CONCERNED THAT IN TWO YEARS I'LL HAVE TO REPLACE THIS ALSO. THE CUSTOMER SERVICE PERSON ASKED IF I DRIVE IT IN AREAS THAT THERE IS A LOT OF DUST. THE ANSWER WAS NO, BUT SHOULDN'T IT BE MADE TO KEEP DUST OUT? AFTER ALL, IT IS ON THE EXTERIOR OF THE CAR.
