2015 Hyundai Genesis

The vehicle exhibits a severe vibration and shaking at normal highway speeds, most notably around 70–80 mph. The condition is repeatable and occurs during steady freeway driving. The vibration is strong enough that the vehicle feels unstable and unsafe to operate at typical highway speeds. This condition significantly affects safe freeway operation. Due to the severity of the shaking, I no longer feel comfortable or safe driving the vehicle at or above normal traffic speeds, which increases risk when merging, maintaining speed with traffic, or responding to road conditions. The problem has been reproduced and confirmed by authorized dealerships. Multiple inspections and repair attempts have been performed over several months for the same vibration concern. Major drivetrain components, including the rear differential and driveshaft, were replaced, but the vibration remains unresolved. The servicing dealer has stated they do not have a further diagnostic path and are unable to continue addressing the issue. The issue has been ongoing since approximately November 2024 and has not been resolved despite repeated service visits. No warning lights or messages are present. The vibration is speed-dependent rather than engine-speed-dependent. The vehicle remains available for inspection upon request.

WHEN DRIVING DURING HEAVY RAIN ON THE EXPRESSWAY THE CAR BEGINS TO FISHTAIL OUT OF CONTROL. IT FORCES THE DRIVER TO DROP THEIR EXPRESSWAY SPEED TO ABOUT 45 MILES PER HOUR. ALL THE OTHER TRAFFIC CONTINUES TO PASS BY SAFELY AT SPEEDS OF 60 TO 65 OR MORE. THIS IS A DEFINITE SAFETY ISSUE. WHEN IT BEGAN, I WAS NEARLY REAR-ENDED BY A SEMI WHEN I WAS FORCE TO DRIVE SLOWLY IN THE RIGHT LANE AT ONLY 40 TO 45 IN A 70 MPH ZONE. IF I DARED TO EVEN TRY TO GO ANY FASTER THE CAR WOULD BEGIN FISHTAILING. NONE OF THE OTHER TRAFFIC HAD ANY ISSUE GOING FASTER, AND I NEVER EXPERIENCED THIS IN THE 2013 GENESIS I HAD PREVIOUSLY. I HAVE READ OF SIMILAR COMPLAINTS AND HAVE BEEN TOLD THAT THE CAR IS REACTING TO ITS FRONT SENSOR BEING 'BLINDED'. THIS IS DEFINITELY A DESIGN FLAW, AND THERE DOES NOT APPEAR TO BE ANY WAY TO DISABLE OR INFORM THE CENSOR TO IGNORE THE PRESENT SITUATION.

HYUNDAI IS TELLING ME THE PROBLEM WITH TIRE TREAD WEAR IS A PROBLEM WITH THE TIRE MANUFACTURER. THE TIRE MANUFACTURER IS TELLING ME THE PROBLEM IS WITH A DESIGN OF THE 2015 GENESIS SEDANS SUSPENSION. INSIDE REAR TIRE WEAR IS EXTREME, AND HAD I NOT COMPLAINED ABOUT VIBRATION AND CABIN SOUND, ULTIMATELY SEEKING PROFESSIONAL HELP IN SEEING THE WEAR AT A TIRE COMPANY, WE MIGHT HAVE VERY EASILY LOST OUR LIVES. LOOK AT 2015 HYUNDAI GENESIS BLOWOUTS / SAUDI ARABIA. MANY, MANY POSTS ON-LINE ABOUT THIS TIRE WEAR HAPPENING HERE IN THE U.S. OUR MICHELIN TIRES ARE WARRANTED TO 45 K MILES, WE WERE ADVISED BY OUR CARS DEALER (HYUNDAI OF EVANSVILLE) TO REPLACE AND ALIGN THE 4 WHEELS, AT A LARGE COST, THIS IS AT 22,914 MILES ! RABEN TIRE, A MICHELIN DEALER, HERE IN EVANSVILLE TELLS ME THE CAR MAY VERY WELL HAVE A SUSPENSION-ALIGNMENT PROBLEM. IT WILL COST US OVER $1000.00 TO BE SAFE FOR A WHILE WITH TIRE REPLACEMENT AND ALIGNMENT. HYUNDAI WILL NOT EVEN GIVE US THE SATISFACTION OF A RETURN CALL. IT IS A BLATANT CASE OF 'DAVID VS GOLIATH' ! EXTREME CABIN SOUND @ 45 TO 50 MPH, AS WELL AS SEAT AND STEERING WHEEL VIBRATION WHILE IN MOTION, UP THROUGH HIGHWAY SPEEDS.

I TOOK MY CAR TO DEALER DUE TO EXCESSIVE NOISE IN FRONT OF CAR WHEN DRIVING. I THOUGHT IT WAS A WHEEL BEARING NOISE. DEAL,ER SAYS NOISE IS DUE TO TIRE WEAR. CAR ONLY HAS 40,700 MILES AND THERE WAS A RECALL AT AROUND 12,000 MILES WHEN HYUNDAI REPLACED ALL FOUR TIRES WITH MICHELIN TIRES "DUE TO COMPLAINTS OF EXCESSIVE ROAD NOISE". MY CAR HAS BEEN REGULARLY SERVICED AT HYUNDAI DEALERS. I TOLD THE DEALER THAT IT WAS IMPOSSIBLE FOR MICHELIN TIRES TO WEAR OUT IN LESS THAN 28,000 MILES. I BELIEVE THE CAR HAS A SUSPENSION DESIGN PROBLEM. THE DEALER REFUSED TO DO ANYTHING ABOUT IT. I CALLED THE HYUNDAI FACTORY LINE (DEALER GAVE ME PHONE NUMBER). FACTORY REP TOLD ME I WOULD BE CONTACTED WITHIN A WEEK BY FACTORY REGIONAL MANAGER. I HAVE NOT BEEN CONTACTED YET. I BELIEVE THE CAR HAS A SUSPENSION GEOMETRY OR DESIGN PROBLEM IN THE FRONT END OF CAR. NO NEW CAR WITH LESS THAN 28,000 MILES SHOULD WEAR OUT A SET OF TIRES UNLESS SOMETHING IS WRONG WITH THE DESIGN OR GEOMETRY. THE FACT THAT HYUNDAI RECALLED THE CAR WHEN NEW (ONLY 12,000 MILES) TO REPLACE THE TIRES TELLS ME THEY KNOW SOMETHING IS WRONG.

AFTER TIRE RECALL AND COMPUTER UPDATE WE FIRST NOTICED A VIBRATION OR SHUDDER FOR THE FIRST FEW MILES. DEALER EVENTUALLY CHANGED 23 SEPARATE TIRES AND PROBLEM PERSISTS. M. STAHL OF HYUNDAI STATES THIS IS A CHARACTERISTIC OF LOW PROFILE TIRES. ELECTRICAL PROBLEMS BEGAN SHOWING UP ON A ROTATING BASIS. INCLUDING, PARK ASSIST NOT WORKING REGULARLY. VENTILATION CHANGING ON ITS OWN. BLIND SPOT INDICATORS NOT WORKING. REAR WINDOWS NOT WORKING. HEATED SEATS NOT HEATING. DASH DISPLAY CHANGES ON IT'S OWN. FOLDING MIRRORS NOT FOLDING AS THEY SHOULD. CAR WENT DEAD ONCE. ZERO ACCELERATION TWICE WHEN MERGING INTO TRAFFIC. SMART TRUNK NOT FUNCTIONING. VENTS BLOWING ICE COLD AIR WITHOUT AC BEING ON. MOST OF THESE HAVE BEEN PHOTOGRAPHED OR VIDEOD. DEALER EMPLOYEES HAVE ALSO WITNESSED MOST OF THESE. OCCURRENCES HAVE BEEN IN ALL DRIVING CONDITIONS FROM STATIONARY, BACK ROADS AND HIGHWAYS. I HAVE ALL REPAIR ORDERS DOCUMENTING OVER 60 DAYS OF LOSS OF USE WHILE CAR WAS AT THE DEALER.
