What 305 owners told NHTSA about the 2015 Hyundai Genesis Coupe

While driving approximately 35–40 mph, the steering wheel locked unexpectedly. My [XXX] child was in the vehicle at the time. I was nearly unable to control the vehicle, creating a serious risk of a crash or fatal injury. The vehicle has a long history of electrical problems including repeated battery failures and a prior transmission replacement. Due to the steering failure, the vehicle is unsafe to operate and has not been driven since the incident. No warning lights were observed prior to the steering failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

So there are TWO main points of concern on this vehicle, number 1 being the steering racks. Many other people have had the same issue as myself. Steering rack completely shut down about a year ago on the freeway, rendering my steering completely useless which was extremely dangerous. 8K repair bill that Hyundai will not acknowledge. Now that comes to my 2ND point, the oil pressure sensor switch. It’s more common than the steering racks. Many owners are reporting it as low at 40-50K miles, yet there’s an open recall in Korea for this exact problem. But the USA does not get any acknowledgment for it??? Yet another costly repair due to defective engineering. Might I add as well, the transmissions Prior to 2018 no matter if you’ve had them replaced, they end up failing and people get absolutely 0 help with them. It’s ridiculous and these issue can eventually cost someone their life some day.

My 2015 Hyundai Genesis 3.8 AWD has steering issue. The steering wheel "sticks," not returning to the center on its own when steer more than 20 degrees either to the left or right. For example, on a winding road or on a corner, I would turn or rotate the steering wheel either to the left and right, and the wheel will stay that way rather than returning to the center once the road become straight. I have to yank the wheel back to the center in order to keep the car on the road. On a highway, I have to make constant correction to keep the car center or hold the wheel firm in order to keep the wheel, therefore, the car stady and and safe. THIS IS A SERIOUS SAFETY ISSUE. I had an extend warranty until April 2025, and such brought the issues to 2 different dealers but they did not help. Each dealer attributes the steering issue to 2 separate problems. One dealer pointed to the rotors (which is relatively news) and the other to a suspension. I know about car. I changed the rotors myself and the suspension. A friend no is a master mechanic himsefl inspect the car for this year's annual safety inspection, and he found no issues withe neight the rotors or suspension after I made the replacments. THE STEERING ISSUE PERSISTS. If you would search the web( suchas Genesis Forum and others) other people have exactly same issues, so much so, Hyundai has issue a technical bulletin to deal with the steering issue under the question, e.g., replace entire steering column. Hyundai should replace all vehicle wiht the issue because this is clearly safety issue to me and any body who are on the road, for god forbids, I could lose control of my car and mawn them over! NHTSA has to at least lauch an investigation. The issue is not mine alone, other GENESIS G80 owners are driving unsafe car as of now! THANK YOU.

Electric Assisted Steering sporadically locking up during turns, requiring effort to unlock. Other times it will lock during hwy driving requiring significant effort to steer the vehicle. Once under 60 mph it unlocks and goes back to normal. This has been happening unexpectedly and without any warnings. Stopping and shutting down the vehicle then restarting will also reset the steering.

The steering wheel frequently locks in position during left or right turns at speeds between 30 and 70 mph. A deliberate effort is required to return the steering wheel to neutral. My Hyundai dealer shop would not diagnose the problem due to the problem being intermittent, despite the car being under the bumper to bumper warranty.

Driving and car just quit. Clock turned, wipers went crazy, and then smoke came up the front windshield from the engine. I bailed and left it in the road. Awful and dangerous situation. Dealership wasn’t excepting Genesis anymore. Towed to a dealership 50 min away. Told the engine failed.

Steering wheel sticks in turns, requiring the wheel to be pulled back to center. This is most noticeable on long sweeping highway turns and adds additional effort to operating the vehicle. This is the second time I've had this problem. The first time, at approx. 30k miles, the Hyundai diagnosed and replaced the electric power steering rack, which resolved the issue. Now at 65000 miles, the same issue has returned. There are a number of other people posting on the genesis forums about this same issue.

theres multiple of vehicles like mines that are having the battery terminal issue. and when its loose it cause the car to shut of while at high speed causing the driver to loose power steering and brakes.

NHTSA ODI 11508464

The positive battery terminal has a design flaw where it will wholly lose conductivity with the battery post due to vibrations, stress and age. After numerous dealer visits where "nothing was wrong" I began to diagnose the issue myself. I tracked it down to faulty positive battery terminal, which due to the lack of manufacturer availability I had to correct myself. It seems to be such a widespread but "unknown" issue with the entire vehicle model that I made a repair guide on the subject with photos: https://genesisowners.com/genesis-forum/threads/improved-positive-battery-terminal-box.32768/#post-411757 The primary issue at stake is the sudden, unexpected loss of power steering when maneuvering at low speeds. The vehicle will lose additional safety systems when the battery power is interrupted, such as collision avoidance, parking sensors, airbags and even powertrain control in extreme cases. No manufacturer diagnostic codes will ever be set as the systems in the vehicle do not account for sudden unexpected power loss. Problem is aggravated by objects on trunk floor resting on terminal box. The secondary issue is that when a power interruption occurs while the vehicle is in operation, the vehicle will not properly shut down when the ignition is turned off. Rather than unlocking doors and assisting handicapped drivers via the easy exit seat feature, the car completely dies and does not wake back up. Vigorous door slamming or any other large impact to the body of the car will sometimes bring systems back online, by fractionally moving the positive battery terminal. If systems do not return, the driver is unable to lock the doors or open the trunk. Hyundai does not make the positive terminal a replaceable item, rather, it's only sold as a combined part with a $1400 battery cable (plus 8 hours labor). Dealers and owners alike are averse to replace this part for such a high price, when the battery terminal itself is worth less than $20.

Upon driving many warning lights light up and make warning signals on the instrument dashboard. These warning lights light up at the same time or in succession and include: check bid system, tire pressure, check engine light, skid control, check bsd system, and others. In addition, brakes become sticky and steering is affected. Worse yet, car slows down on its own as it engages crash avoidance system.

ESC failed. I was attempting to make a left turn from a stopped position at a typical intersection. I lost control of the vehicle as it started to fishtail once I began the turn. Brakes did not respond and I ended up hitting the curb on the outer lane with both front and rear tires. Side curtain and passenger seat airbags deployed. Vehicle is now a total loss. I believe the faulty ESC poises a lot more risk that just a fire. From other reports on genesis forums by consumers like me, this problem with Hyundai's ESC seems to be a common and reoccurring problem. Recall should be updated to include that ESC may fail and makes the vehicle unsafe to drive.

SINCE LAST OCTOBER, THE CAR'S STEERING HAS PERIODICALLY FAILED TO RETURN TO CENTER, AFTER TAKING A RIGHT HANDED CURVE. THE CAR JUST KEEPS TURNING. WE HAVE TAKEN THE CAR BACK TO THE DEALERSHIP WHERE WE LEASED IT; HOWEVER, THEY HAVE REPEATEDLY FAILED TO FIX IT. I HAVE LOOKED THE PROBLEM UP ON THE INTERNET AND FOUND THAT IT IS DEFINITELY A SAFETY PROBLEM THAT MUST BE FIXED. WHY NOT FIX THE PROBLEM BEFORE PEPLE GET HURT?

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.
