Hyundai Genesis key fob problems

Filed Jan 31, 2025 · Electrical, Visibility · WA

The trunk of the car stopped opening with the “open trunk button” from inside the car and also does not work with the key fob option. The trunk now needs to be opened by key from key fob everytime. Water is leaking through the trunk of the car and cause to have mold in the car. An electrical problem with the audio of the car stopped working. The radio or bluetooth no longer works due to the audio no longer working. The driver side front window does not work due to an electrical problem.

Driver's side passenger door lock does not electronically function--either by key fob or by driver's control. Passenger door must be manually locked and unlocked. This defect was present from time car was purchased new but was only discovered after car was out-of-warranty since passenger door had never been used until grandchildren began using back seat. This represents an safety hazard in the event that back-seat passenger needs to exit car quickly via electronic means. We are aware that this defect is quite common among 2012 Hyundai Genesis owners. Hyundai Motors of America knows that this was a manufacturing design defect but thus far, is unwilling to support warranty repair. Warranty repair is quite costly, averaging $700-900, and this is likely the reason why HMA has elected to publicly hide and ignore the issue.

Vehicle shuts off at red lights or when making very low speed turns. Indicator on dash shows 'KEY' symbol and sometimes battery symbol. I then have to shift to park or neutral to push button restart vehicle. Other times I'm parked with vehicle idling and it simply shuts off. This issue puts me at risk because it shuts off while driving on public roads with other vehicles. The repair shop can't find out why this is happening and the vehicle flashes no check engine light and there are no stored codes. This began a couple months after I had a new battery installed in the vehicle and put a new battery in the key fob. Vehicle now, no longer recognizes key fob. I have to manually insert key fob into a key fob slot inside vehicle in order to crank it. This seems to be an issue with the 2012 model Genesis, as I have read on several online forums of other owners experiencing the same problem.

The left rear passenger door does not open from inside or outside. I have looked online and see that this or similar problems affect many Genesis sedans as well as other Hyundai vehicles. We needed to seat two young children in the back seat and realized how dangerous it is if something happens and the car door can't be opened from inside or outside. How would rescue teams extract the passenger? How could the passenger extract him/herself? Many people reported paying a lot of money to the dealership to repair this problem. I believe this is a safety hazard that the company should be responsible for. This problem began recently, with no warning. The key fob does not open the door either.

Front inside door lock switch (driver's side) remains in the unlatched position when I attempt to lock door via lock button from inside of car or via key fob from the outside of the car. All other doors (front passenger, left rear, right rear) lock just fine. Hazard: the door may not be in the locked position and may open while the vehicle is in motion, possibly resulting in injury to the driver.

Parked in parking lot on slight uphill incline. Took phone call as I stopped and forgot to put in park. After call ended, hit "off" button which is hidden behind steering wheel. Thought motor was "off" but really only on "acc". Opened door & started to get out. Car started to roll backwards. Able to get back in and put foot on brake. Car rolled about 10 yards before I stopped it. Happily, nothing was behind the car. The open door could have hit me and swept me under car but I was able to avoid it as I got back in. No harm to me or car but dangerous situation. Reported to hyundai & they said there was no fix other than to be sure car is in park before turning it off. With older cars with a key, could not take key out of ignition unless car was in park. But with key fob and push button ignition, that "fail safe" is no longer available.

After second time another window lift (failed without any use) fell down, went to dealer for repair. [the darkened window films were left scratched with open spaces at each repair.] auto released to customer for a few days until parts would arrive, after recall service. Was told stop lamp switch replacement would fix all previous ESC and transmission lockup complaints. Not! After leaving dealership when slowing to 20 MPH with electronic doors locked and windows closed, tapped brake, caused automobile to lurch violently to a sudden stop in rush hour traffic. Smoke filled the interior and neither doors nor windows would open, and dash lights flashed intermittently on a random basis, with out logic, and died. Auto was immobilized and could not be shoved nor driver extracted by fire department response (2). Eventually was able to cause passenger power window (only) to lower halfway during final flash from lights. With help was able to escape. Trunk was opened with manual key (key fob inoperative) and swelled battery was melting down, with ventilation, did not explode. The oem battery location failed by sedimentation shorts from a "goosey" suspension. Dealer retrieved vehicle, after window lift replaced, demanded customer removal by putting bad battery from another vehicle in for jump start. Drove to nearest after market store for adsorbed glass mat (agm) battery to preclude future fires. Driver's door actuator total failure replaced (37631). Brake light switch replaced again (46704). Brake switch diode recall refused by dealerships that continue to also refuse to adjust emergency free play, at any cost. Porous oem tires replaced for safety. This car is considered unsafe to drive unless one window remains lowered for an escape path.

The car will not start when the temp outside is ~40 degrees f or lower outside. It will crank non stop (push button start) but won't ever start. Car battery is only two months old. Cranks fine when the outside temp raises back up to around 45 degrees f and up. While driving today on the interstate, on the bridge, the car randomly lost all engine power. Trying to step on the gas pedal would result in the car studdering. I turned on the emergency signal and just cruised into the side lane out of traffic. Turned the car off and on and noticed the RPM idled at 1500 RPM which is insanely high. I put it in 1st gear and gave it gas, and nothing happened. The RPM meter wouldn't go up. After a few more times of cutting the engine on and off and the engine wouldn't start a few times also, it finally started and seemed to work normally. Now the car has a check engine light on.
