2010 Volvo S40 Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

I WAS DRIVING 65MPH ON HIGHWAY 101, JUST SOUTH OF WILLITS, CALIFORNIA, WHEN MY SUNROOF EXPLODED. I HEARD A LOUD EXPLOSION SOUND AND IMMEDIATELY PULLED OVER TO FIGURE OUT WHAT JUST HAPPENED. I COULD SEE THAT MY SUNROOF WAS MOSTLY GONE AND THERE WAS PIECES OF GLASS FALLING ON ME. I CALLED MY HUSBAND TO HELP CALM ME DOWN, AS MY HEART WAS RACING AND I WAS SHAKING. I PUT MY HAZARDS ON AN PULLED OVER A LITTLE MORE FOR SAFETY. JUST THEN I NOTICED A MAN WALKING TOWARD ME FROM FURTHER UP THE HIGHWAY. I GOT OUT OF THE CAR AND COULD HEAR THE CONVERSATION THAT THE MAN WAS HAVING WHILE ON HIS PHONE. WHEN HE HUNG UP THE PHONE, HE STATED THE HE CALLED 911. THE MAN EXPLAINED THAT HE WAS PASSING ME AND WITNESSED WHAT LOOKED LIKE ICE COMING UP OUT OF MY SUNROOF AND IT HIT HIS CAR. THE MAN WAS VISIBLY UPSET, BUT COULD SEE THAT I WAS NOT AT FAULT, AND ACTED APPROPRIATELY. THE MAN SAID THAT THE GLASS HAD CHIPPED THE CAR THAT HE WAS DRIVING. HE APPEARED AS SURPRISED AS I WAS ABOUT THE SITUATION. THE MAN HELPED ME TO PICK UP THE LOOSE GLASS AND THE GLASS ON MY SEATS. HE THEN SUGGESTED MOVING UP THE ROAD A FEW HUNDRED FEET WHERE HE WAS PULLED OFF, AS THE HIGHWAY PATROL WERE IN ROUTE. THE HP MADE SURE THERE WERE NO INJURIES AND ASKED THAT WE EXCHANGE INSURANCE. WE BOTH TOOK PICTURES, I GAVE MY INFORMATION TO ONE OF THE CHP OFFICERS AND DROVE HOME. I IMMEDIATELY CALLED MY INSURANCE COMPANY. WHEN EXPLAINING WHAT HAPPENED TO THE AGENT HE STATED THAT HE HAD NEVER HEARD OF THIS HAPPENING, WHICH PROMPTED ME TO RESEARCH "EXPLODING WINDSHIELDS" AND LED ME TO SEVERAL ARTICLES ON THE MATTER. I AM NOW RESPONSIBLE FOR NOT ONLY FIXING MY CAR, BUT ALSO THE PAINT JOB ON THE CAR OF GENTLEMAN WHO WAS PASSING ME ON THE HIGHWAY WHEN IT OCCURRED.

MY HUSBAND AND I BOTH OWN 2010 VOLVOS. MINE IS S40, HIS XC60. WE HAVE BOTH HAD LEAKS RELATING TO FAULTY SUNROOF DRAIN. DEALER REPAIRED AND REPLACED FOR MY HUSBAND AT NO COST, BUT FOUGHT WITH ME - BECAUSE I AM A WOMAN - UNTIL MY HUSBAND CAME WITH ME TO DEALERSHIP. EVEN THOUGH THEY ULTIMATELY FIXED THE SUNROOF DRAIN, THERE IS STILL THE STENCH OF MOLD OR MILDEW IN MY CAR. MY HUSBAND ALSO HAD A LEAK DEVELOP IN HIS WINDSHIELD. DEALER TOLD HIM THAT THERE WAS A FAULTY COATING ON WINDSHIELDS THIS MODEL YEAR AND THEY REPLACED HIS WINDSHIELD AT NO COST. JUST NOW, I WAS OUT DRIVING, IT STARTED RAINING, AND WATER STARTED POURING IN THROUGH MY WINDSHIELD. (LUCKILY I WAS JUST ARRIVING AT MY DESTINATION, AND I WAS ABLE TO WAIT UNTIL THE RAIN SUBSIDED BEFORE DRIVING HOME, BECAUSE THERE WERE MULTIPLE STEADY STREAMS OF WATER POURING ON TO ME AND THE STEERING WHEEL WHEN THE RAIN WAS AT ITS PEAK.) APPARENTLY MY WINDSHIELD HAS THE SAME PROBLEM THAT MY HUSBAND'S HAD. I KNOW THERE IS ALREADY A CLASS ACTION LAWSUIT BREWING ABOUT THE LEAKY SUNROOF DRAIN, AND I SEE THAT THERE ARE HUNDREDS OF PEOPLE ONLINE COMPLAINING ABOUT THIS. I ALSO SEE THAT THERE ARE LOTS OF PEOPLE ONLINE COMPLAINING ABOUT THE WINDSHIELD LEAK. THIS IS RIDICULOUS. HOW CAN VOLVO KNOWINGLY LET BUYERS OF ITS CARS DRIVE AROUND KNOWING THAT THEY ARE IN DANGER OF HAVING RAIN POUR IN ON THEM AS THEY ARE DRIVING? OR THAT THE INTERIORS OF THEIR CARS WILL BE SOAKED AND POLLUTED WITH MOLD AND MILDEW? IS NHTSA GOING TO DO SOMETHING ABOUT THIS????

I got into a car accident today. The electrical wiring is constantly giving out and I had no idea my airbags wouldn't work until today when they did not deploy. My car hit the other car enough to move it several feet and no airbags.

The adhesive and seal on the entire top of my windshield has failed. The glass is shaking while driving and rattles severely if a small bump is driven over on the road. This is a huge safety concern since my window could break or fall off at any given moment.

The windshield is coming unglued at the top center and right . I am concerned that the windshield could come out on the highway, I plan to contact a windshield shop and see if they can repair it.

THE SEATBELT BUCKLES STICK WHEN TRYING TO EJECT. THE BUCKLE CLASPS HAVE TO BE PUSHED DOWN AND WIGGLED A FEW TIMES TO UNCLASP. THIS IS A SERIOUS SAFETY ISSUE BECAUSE IT'S IMPOSSIBLE TO EXIT THE CAR QUICKLY. THIS IS ALL BELTS IN THE CAR. THIS HAS HAPPENED SINCE THE CAR WAS NEW AND HAS GOTTEN WORSE. *TR

I WAS PROMPTED TO ADD AIR TO MY FRONT TIRE DUE TO THE LOW TIRE PRESSURE LIGHT COMING ON. AFTER I ADDED AIR I ATTEMPTED TO PUT THE TIRE VALVE CAP BACK ON THE WHEEL AND IT BEGAN FORCEFULLY BLOWING OUT AIR. I ATTEMPTED AGAIN TO SECURE THE CAP AND THE VALVE STEM SENSOR CAME OUT OF THE VALVE STEM COMPLETELY. THIS IS A HUGE SAFETY RISK, AND I AM NOW CONCERNED THIS COULD HAPPEN AGAIN. I URGE VOLVO TO HONOR THE REPLACEMENT OF THEIR FAULTY TIRE STEM VALVES IMMEDIATELY
