What owners report

Owners of this model year most often describe transmission problems — manual-gearbox grinding and gear rejection, and automatic gearboxes that shift or downshift on their own. Brake complaints form the second cluster: a pedal that goes soft or to the floor and stopping distances that grow, in some cases on cars the owner says were left out of a related campaign. A smaller set of reports covers electrical and no-start faults and airbags that did not deploy in a crash. Many transmission reports come in at low mileage, while brake reports tend to arrive much later in the car's life.

  1. Brakes

    Brake pedal goes soft or to the floor

    • 9 complaints (13%)
    • median 68,250 mi at 6.9 yrs old (6 state mileage, few)
    • filed 2011–2023

    Complaints describe the brake pedal travelling to the floor or responding slowly, with longer stopping distances and a need to pump the pedal to stop. In some reports the dealer pointed to a contaminated hydraulic unit or a failed brake booster, and owners note that their car was not covered by a related brake campaign. Others describe a pull to one side or a caliper running much hotter than the other side. Mostly reported between roughly 50,000 and 80,000 miles, sometimes after a recent brake service.

    2 related service bulletins

    What to check: Press the pedal firmly with the engine running and check it holds rather than sinking. Ask for service records on the hydraulic unit, booster and calipers, and check by VIN whether any brake campaign applies.

    2 excerpts from owner complaints in NHTSA records

    “When applying pressure to my brake petal, the car did not stop. I almost was involved in a few rear end collisons. It was very scary! Dealership checked the brakes and nothing is wrong. I need to do a master cylinder change. Unfortunately, my car is no longer under warranty. Currently, it has 53,000 miles only. No recall for my vehicle.”

    NHTSA complaint #10995753, filed 2017-06, 53,000 miles

    “The brakes on my 2010 Genesis Coupe suddenly stopped working while on the freeway, luckily I was able to swerve into the carpool lane and avoid an accident. Upon taking it to Tuttle Click Hyundai I was told a master technician had to review it, which would cost $200 just to look at it. When the technician looked at the car, I was told it needed a new Brake Booster. Hyundai apparently no longer makes this part so the dealership had to locate an aftermarket replacement which costs about $1,100. …”

  2. Transmission and drivetrain

    Manual transmission grinds or refuses gears

    • 10 complaints (15%)
    • median 31,500 mi at 3.0 yrs old (10 state mileage)
    • filed 2011–2018

    Owners of manual cars describe grinding when engaging certain gears, most often second, third and fifth, and times when the lever simply will not go into the requested gear. Several say it is most noticeable when the car is cold, and that a fluid change or a replacement gearbox did not stop it. Complaints describe dealers either replacing the transmission under warranty or telling the owner they could not reproduce the noise. Most reports come in below about 50,000 miles, and several tie the grinding to cold temperatures.

    4 related service bulletins

    What to check: On a manual car, drive it cold and shift through every gear, especially second and fifth, listening for grind and feeling for lockout. Ask whether the transmission oil campaign or any gearbox replacement was done.

    2 excerpts from owner complaints in NHTSA records

    “Transmission is difficult to shift at times mostly into second gear. This can cause a rapid deceleration in traffic and I have seen the vehicle behind me do a nose dive hitting the brakes because my vehicle disrupted traffic flow. Entering fast moving traffic is also a concern for this very reason. Dealer has replaced transmission several times with no change in transmission behavior.”

    NHTSA complaint #10418958, filed 2011-08, 3,029 miles

    “While driving my 2010 Hyundai Genesis Coupe 3.8l track model, I experience severe problems with the transmission. When shifting from 1st gear to 2nd gear whenever the temperature is below 30 degrees fahrenheit the transmission grinds going into gear. Hyundai USA had a TSB about it, and the transmission fluid was changed under warranty. A week later the problem is still occurring. Hyundai has not been helpful in fixing the problem whatsoever since. …”

    NHTSA complaint #10446698, filed 2012-02, 16,000 miles
  3. Transmission and drivetrain

    Automatic shifts on its own or holds revs

    • 7 complaints (10%)
    • median 58,947 mi at 3.5 yrs old (7 state mileage, few)
    • 1 mention a crash, fire or injury
    • filed 2011–2014

    Owners of automatic cars describe unexpected downshifts, getting stuck in a gear, and engine speed rising on its own so the car speeds up or slows without the accelerator being pressed. Some complaints say the dealer found a failed transmission control module or could not duplicate the behaviour; others report repeated dealer visits without a lasting fix. Reported from a few thousand miles up to about 70,000 miles, across a range of driving conditions.

    4 related service bulletins

    What to check: Test drive an automatic through stop-and-go traffic and watch for delayed or harsh shifts and hanging revs. Ask whether any transmission control module work or adaptive relearn was performed.

    2 excerpts from owner complaints in NHTSA records

    “I have a 2010 Hyundai genesis 3.8 coupe 6-speed automatic with paddle and sport shift. I have had an ongoing issue with the vehicle for several months now not shifting properly. Sometimes it wont shift out of 1st gear and when it does it will unknowingly downshift and get stuck in a gear. Since the issue began, I have received several speeding tickets and had near death experiences due to the shifting. …”

    NHTSA complaint #10519502, filed 2013-06, 63,000 miles

    “While driving the car, the car speeds up on its own without me pushing the accelerator. The car also has rev hang and the rpms rise by its self and stays their. Usually between 6500rpm. I have to press the brake in order for the rpms to drop so its doesn't blow the motor.”

    NHTSA complaint #10615778, filed 2014-07, 67,000 miles
  4. Electrical system

    No start, push-button and brake switch faults

    Mentioned in 7 of 60 sampled complaints

    Complaints describe the push-button start going only to accessory mode, intermittent no-starts traced to a brake switch or hydraulic control unit, brake lights that stop working, and warning lights coming on with the car stuck in gear. Several owners report parts replaced more than once without the fault going away, and one mentions the shifter being hard to move out of park. Reported from under 10,000 miles through to around 140,000 miles, often as an intermittent fault.

    Recall 13V113000Recall 24V5620002 related service bulletins

    What to check: Start the car several times from cold and check that the brake lights work and the shifter releases from park. Ask whether the brake light switch campaign was completed and whether the battery has been replaced.

    2 excerpts from owner complaints in NHTSA records

    “I began having this issue 10 days ago with my 2010 Genesis Coupe. The concern I had was not only was the interior flickering but it resulted in my running night brake lights not working. I took the car to the dealer I'm at 62k miles just out of warranty. They ran diagnostic and thought it was a lose bracing for the wires. I picked it up and the issue began again. I took it in 4 days ago they then said it was a fuse switch issue and replaced it but the issue continued. …”

    NHTSA complaint #10627852, filed 2014-08, 62,300 miles

    “This car has been a headache since it went out of warranty (ironically). First it was the car wouldn't start due to an electrical problem between the alarm system and key fob. The starter was the next to go. Most recently the fuel pump went literally while I was driving the car. Fortunate I was able to make my way off the road and avoided collusion and possible physical injury. There were no warnings that there were any issues with the car, no dashboard warnings, no usual performance. The car was fine one second and completely dead the next. …”

    NHTSA complaint #10889130, filed 2016-07, 135,000 miles
  5. Air bags

    Airbags that did not deploy in a crash

    • 6 complaints (9%)
    • median 22,805 mi at 4.3 yrs old (6 state mileage, few)
    • 6 mention a crash, fire or injury
    • filed 2011–2019

    Owners describe collisions and rollovers in which some or all airbags stayed folded, including side and overhead bags and the passenger bag with an occupant seated. Some complaints also mention an occupant-classification or harness issue on the passenger seat. These are reports from individual crashes rather than a described pattern of everyday symptoms. Reported across a wide mileage range, in crashes from low mileage up to about 95,000 miles.

    Recall 16V7220003 related service bulletins

    What to check: Check that the airbag warning light behaves normally and ask whether the passenger seat occupant-classification recall work was done. Moving the passenger seat with the ignition on lets you see if the airbag status indicator responds.

    “In april 14 2012 around 2am nj atco I was rear end from behind about 40mph, I was accompany by my cousin he sat on the passenger side. Most of the damage was done on his side. I drive a Hyundai Genesis Coupe 2010. His side air bag did not deployed.. I can provided pictures if needed. Is there any way can I sue the car company or the manufacture of the airbag for failure to deploy.”

    NHTSA complaint #10464640, filed 2012-07, 22,000 miles

    “I was making a left hand turn onto route 25 in ridge, new york and was struck by a speeding vehicle (I would estimate at 65 MPH +) on the left front quadrant. The genesis (my car) was totaled as a result. My complaint is that none of the air bags deployed.”

    NHTSA complaint #10396305, filed 2011-04, 9,050 miles

Buying note. Check the gearbox and brakes carefully on a test drive: shift through every gear on a cold manual, watch for odd automatic shifting, and make sure the brake pedal stays firm. Ask for records on recalls and service campaigns by VIN, since several owners report their car was not covered by a related campaign.

Example complaints

Transmission and drivetrain: “I bought the car used with 32,500 miles. From day 1 there was a grind going into 5th gear. This was a known problem, but no TSB or recall was ever sent out about it. Just a TSB to change the fluid . At 82,000 miles the 5th gear synchro broke. I had to buy a used transmission from the junk yard and had it installed for $820 total including the transmission, labor and fluid. Why would they claim they have a 10 year/100,000 mile powertrain warranty, when it only covers the first owner. And why would they know about the 5th gear grind and not do anything about it.”

NHTSA complaint #10981101, filed 2017-04, 82,000 miles

Brakes: “My vehicle was parked in a parking spot on a slight incline with the parking brake engaged and the stick left in 1st gear. My vehicle then rolled <12 inches into the vehicle parked in front of it.”

NHTSA complaint #10396003, filed 2011-04, 4,700 miles

Electrical system: “The vehicle brake lights stop working. The car will not start normally and will not shift normally. A fuss will fail over and over again. Hyundai dealer identified that the hecu is faulty.”

NHTSA complaint #11416322, filed 2021-05, 140,000 miles

Vehicle speed control: “When starting the vehicle with foot on the clutch, it lurched forward hitting a parking barrier. Dealer denied mechanical causes. From the time I bought the car, it has accelerated on it's own, going to the max in rpms, at random times. I can take my foot off the gas and it will drive itself. When I try to come to a stop, it will accelerate and I have to counter by hitting the brake. When taken to the dealer, they couldn't replicate it. When I argued with the man, he said he would honor the warranty when they could replicate it, though the warranty is now expired. …”
