2015 Hyundai Sonata Suspension Problems

This complaint concerns a repeat failure of both front CV axles on my 2015 Hyundai Sonata. The CV axles and boots were replaced by Gettel Hyundai of Charlotte County using OEM parts in November 2024. The same components failed again just 7,876 miles later in January 2026; requiring a second full replacement. A CV axle replaced with factory OEM parts by a certified Hyundai tech should not fail within 7,876 miles under normal driving conditions. This pattern of repeat failure indicates either * A defect in the OEM replacement parts supplied by Hyundai * An installation defect at the authorized dealership * An unresolved underlying mechanical condition that causes accelerated CV axle wear The rapid repeat failure represents a potential safety hazard. CV axle failure can result in sudden loss of drive power, difficulty controlling the vehicle, and in severe cases, wheel separation --all of which create dangerous conditions for the driver and others on the road. Chronological Timeline of Events: Nov 5, 2024 55,579 miles; both front CV axles replaced by authorized Hyundai dealership using OEM parts. Labor and parts performed per Hyundai standards. Jan 29, 2026 63,451 miles Same CV axles failed again. Second replacement performed at same authorized Hyundai dealership. Total repair cost $3227.16 paid out of pocket by me. Feb 16, 2026 Hyundai Motor America denied goodwill reimbursement request (Case #XXX), citing the malfunction being out of time in service of the vehicle. Reported to Hyundai Motor, their response did not address the repeated nature of failure, the short mileage interval, or the possibility of a defective OEM part or improper installation. I believe the NHTSA should be aware of this pattern and investigate other 2015 Hyundai Sonata owners have reported similar rapid repeat CV axle failures, which could indicate a systemic defect in either OEM parts or dealership repair procedures.

The contact owns a 2015 Hyundai Sonata. The contact stated while depressing the brake pedal, the vehicle veered to the right. The vehicle was taken to the local dealer and the brake rotors were modified, and the failure was corrected. Additionally, while driving at speeds over 65 MPH, the front driver’s side of the vehicle was shaking and vibrating abnormally. The cause of the failure was not yet determined, and the vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 70,000.

Our 2015 Hyundai Sonata has made a clunking sound when accelerating or slowing down. We took our car to Brandon Hyundai and explained the problem. They had our car for 1 day and said a motor mount and a transmission mount were faulty. They said they did the repairs and that it was covered by warranty. Within a few days the car was making the same sound and we returned it to Hyundai. The next day the car repair was "completed". Again they said it was a motor mount and it was repaired at no expense since it was covered by warranty. The noise returned and we will schedule another appointment to hopefully fix the problem. Our Sonata has 97000 miles on it and we think Brandon Hyundai may be stalling until the warranty runs out. Our family has bought 5 new Hyundai's in the last 10 years and have been very pleased with the cars. I don't blame the vehicle, just the dealer's service department. RVE

2015 Hyundai Sonata 2.4L Hybrid with 35,333 miles has a broken front driver's side strut spring. Contacted Hyundai corporate and was told there is no recall on this year model. Dealer has been contacted regarding repair and they cannot inspect car till Dec. After research this looks the same as NHTSA CAMPAIGN NUMBER: 15V629000 (SUSPENSION). There were no warning indicators and I had noticed a noise and the feeling of suspension issue coming from the front driver's side. Broken spring was found by jacking up the front driver's side wheel.

Vehicle started making a front end noise when turning or hitting a bump.

ON 8/27/20 WHEN I RETURNED HOME FROM RUNNING ERRANDS, I BACKED INTO MY DRIVEWAY. THIS WAS AROUND 3PM AND I DIDN'T USE THE CAR FOR THE REST OF THE DAY. THE NEXT MORNING I WENT OUT AROUND 3AM TO LEAVE FOR WORK. AS I STARTED TO PULL OUT OF THE DRIVEWAY, I HEARD DRAGGING AND STOPPED THE CAR. WHEN I GOT OUT TO LOOK, MY FRONT PASSENGER SIDE TIRE WAS FLAT. THERE WAS NO INDICATION ON MY DASH AT THAT TIME. MY HUSBAND CAME OUT TO FILL THE TIRE FOR ME AND WE ONLY HEARD HISSING AIR. HE THOUGHT THAT IT WAS SO FLAT THAT IT WAS OFF OF THE RIM SO HE JACKED IT UP TO TAKE THE PRESSURE OFF OF THE TIRE. THE AIR WAS STILL BLOWING OUT OF THE TIRE SO HE REMOVED THE TIRE TO CHECK IT AND FOUND THAT THE ENTIRE THING WAS TORN ON THE INSIDE FROM A BROKEN COIL SPRING. I DON'T KNOW IF IT HAPPENED AS I BACKED INTO THE DRIVEWAY THE DAY BEFORE OR AS I WAS LEAVING FOR WORK THAT MORNING. ALL I KNOW IS THAT MY CAR HAS UNDER 63,000 MILES ON IT AND IF THIS HAD HAPPENED ON A HIGHWAY, WHO KNOWS WHAT COULD HAVE HAPPENED TO ME.

THE FRONT LEFT COIL SPRING BROKE WHILE THE CAR WAS PARKED. THE SPRING EXTENDED DOWN SO THAT IT MADE CONTACT WITH THE TIRE.

SOUND COMING FROM LEFT END WITH VEHICLE IN MOTION ON HIGHWAY, WHEN CHECKED, LEFT FRONT COIL SPRING WAS BROKEN.

LEFT FRONT CV AXEL/SHIFT ASSEMBLY NEEDED TO BE REPLACED WITH 61,000 MILES.

MY VEHICLE MAKES A CLUNKING NOISE WHEN I MAKE A TURN AND ACCELERATE SIMULTANEOUSLY, NAPELTON HYUNDAI TOLD ME IT WAS MY AXEL AND MY FRONT BRAKES GRIND WHEN MY CAR SETTLES AFTER I BRAKE OR WHEN I EASE OFF THE BRAKE

I BOUGHT THE CAR IN 2015, CURRENTLY THE CAR HAS LESS THAN 14,000 MILES. WITHIN THIS 3 YEAR AND LOW MILEAGE I HAD EXPERIENCE SEVERAL PROBLEMS 1.- TIRES BREAKS EASILY 2.- ELECTRICAL WIRES INSULATOR HAS BEEN APPLIED WITH VEGETABLES SOLUTION, MAKING FATAL ATTRACTION TO RODENTS 3.- BATTERY DOESN'T LAST OVER 12,000 MILES 4.- SEAT BELTS ARE DEFECTIVES, AND STILL IS 5.- BETWEEN THE TRANSMISSION AND THE TRANSFER CASE THE IS A DRAGGING NOISE 6.- TECHNOLOGY PACKAGE? EXPENSIVE AND MALFUNCTION MAKING THIS SAFETY ISSUE DANGEROUS. 7.- RADIO......PART OF THE TECHNOLOGY PACKAGE STOP WORKING IF YOU STOP HYUNDAI SO CALLED BLUE LINK SERVICE 8.- SCREEN AT MY DASHBOARD WENT BLANK 3 TIMES AT 3,000. 7,000 AND 11,000 MILES 9.- WHILE DRIVING MY VEHICLE ENGINE SHUT OFF AT STOP LIGHT (THANKS GOD IT HAPPENS WHEN I WAS DRIVING LOCALLY) ALL THIS HAPPENS WITHIN THIS 3 YEARS THAT I OWN THE CAR

2 WEEKS AGO, I FOUND IN MY FRONT PASSENGER SIDE TIRE A BAUBLE AND I TOOK THE TIRE TO THE DISCOUNT TIRE TO BE CHECKED. THE TIRE SPECIALIST DISCOVERED OTHER PROBLEMS ON BOTH FRONT TIRES. THE TIRES ARE SEVERELY CUPPED THE INSIDE EDGE. HE RECOMMENDS ME TO CHECK WITH THE SERVICE DEALERSHIP AS SOON AS POSSIBLE, HE NEVER EVER EXPERIENCED THAT TYPE OF PROBLEM IN THE PAST. DEALERSHIP SERVICE WORLD CAR HYUNDAI TOOK THE CAR FOR ENTIRE DAY AND TOLD ME THAT THEY MIGHT THINK IT NEEDS TO BE DONE THE ALIGNMENT. I TOTALLY REFUSED TO DO IT BECAUSE THE ALIGNMENT IS PERFECTLY FINE, MY STEERING WHEEL NOT TURNING IN ANY DIRECTION AND IS NOT SHAKING WHILE I AM DRIVING. THIS IS WHAT I FOUND ON FORUM! HTTP://WWW.SONATAFORUMS.COM/INDEX.PHP?PAGE=ACTIVE_TOPICS

6 ALIGNMENTS WITH TIRE BALANCING, UNTOLD TIRE BALANCING ON OTHER OCCASIONS. THE CAR VIBRATES AT HIGH SPEEDS, MY FIRST SET OF TIRES WORE OUT THROUGH TO THE STEEL BELTS ON THE INSIDE AT 32000 MILES WITH A A GOOD 1/4 IN OF THE TREAD ON THE OUTSIDE LEFT ON THE FRONT TWO TIRES. I'VE COMPLAINED THE FIRST WEEK I HAD THE CAR AND MULTIPLE TIMES SINCE. NOT HUNG VIVIBLE HAS BEEN FOUND. THE TIRE ALIGNMENTS AND BALANCING TO THE NEW TIRES DIDN'T TOUCH THE VIBRATION. MY FEAR IS IT'S A CONTROL ARM OR OTHER FRONT END SUSPENSION ISSUE OR FAILURE THAT'S NOT VISIBLE.
