2012 HYUNDAI GENESIS Unknown Or Other Problems

Submitted complaint of unsafe fumes /gas smells emitting from engine and into cabin of car to site on 10/23/2023 for my vin the complaint I see is under Tires This should be under engine I said nothing about tires it's a 2012 Hyundai Genesis BH 4 door sedan battery wasn't holding charge engine idles high and low poor gas mileage and sluggish brake light always on even after repair

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...

MY VECHILE STALLS WHILE DRIVING AT VARIOUS TIMES. THIS COULD CAUSE A SERIOUS ACCIDENT IN WHICH LIVES COULD BE LOST . THIS EEMS TO BE PROBLEM WITH THE GENESIS FROM 2012 TO 2016 FROM MY RESEARCH. I AM NOT THE ONLY OWNER WITH THIS PROBLEM . THE DEALERS CANT FIND THE PROBLEM OR WHY IT IS OCCURING . THE DEALERS GIVE YOU NUMEROUS REASONS AS TO WHAT MIGHT BE THE CAUSE OF THIS PROBLEM, BUT THEY ARE NOT SURE . THIS COULD COST A CONSUMER $1000 OF DOLLARS JUST TO FIND OUT WHAT THE PROBLEM IS . THIS OCCURS WHEN JUST DRIVING DOWN A STREET, ON CURVES OR GOING STRAIGHT. I HAVE NOT HAD AN ACCIDENT YET! IM TRYING TO AVOID THIS .THIS OCCURS WHEN MY GAS TANK GETS LOW , THAT IS WHAT I HAVE NOTICED .

COMPLETE LOSS OF ALL POWER SUPPLY AND TOTAL MECHANICAL SYSTEM/ENGINE NO LONGER OPERATIONAL

CAR SHUT OFF FULL POWER OFF WHILE ON A RESIDENTIAL ROAD AND I WENT ACROSS THE ROAD UP A SLANTED SMALL HILL AND RAN OVER TREE AND YARD DEBRIS.

NAVIGATION DISPLAY FAILURE RESULTING IN NO BACK-UP CAMERA, NO A/V FUNCTIONS, AND HVAC CONTROL MALFUNCTION. DEALER REPLACED WITHIN APPROXIMATELY 8 MONTHS OF PURCHASE. SYSTEM HAS FAILED AGAIN AND CORPORATE ADVISED THAT THE PART WAS ON BACKORDER AND WE WAITED FOR A REPLACEMENT PART FOR 8 MONTHS. NOW CORPORATE HAS ADVISED THAT THE PART, A-V MONITOR ASSEMBLY PART #965633M851, IS UNAVAILABLE/DISCONTINUED. NO WAY TO REPAIR OR REPLACE THE PART. VEHICLE HAS 44,000 MILES ON IT. SUNROOF FAILED WITHIN FIRST 20,000 MILES AND WAS SEALED TO AVOID EXPENSIVE REPAIR. MOST RECENTLY THE CAR DIED WITHOUT WARNING WHILE STATIONARY. IN FOR EVALUATION NOW. THIS CAR HAS BEEN A CHRONIC PROBLEM SINCE WE FIRST PURCHASED IT AND CORPORATE HAS TOLD US THAT WE ARE AT A DEAD END REGARDING THE A/V MONITOR ASSEMBLY - THERE IS NOTHING THEY CAN DO. A/V MONITOR ASSEMBLY ISSUE OCCURRED IN JUNE OF 2020.

AT APPROXIMATELY 10:30 PM. WHILE DRIVING ON HWY AT FAIRLY GOOD SPEED OF 73-75 MPH, WHILE ON CRUISE CONTROL, THE ENGINE DIED AND STEERING BECAME DIFFICULT TO NONE AT ALL, ALL WHILE ENGINE WAS COMPLETELY OFF. CAR COULD NOT BE STARTED AGAIN. VEHICLE IS CURRENTLY NON-OPERABLE AND PARKED. IT APPEARS I AM THE THIRD OWNER OF THE IS VEHICLE. YOUR ASSISTANCE IS APPRECIATED.

WHEN IN MOTION, THE VEHICLE STARTS TO MAKE A CLANKING SOUND REPETITIVLY AS IF IT WAS ON A ROTATION. IT'S LIKE A METRONOME BEST AT 128BPM

AFER 45000 MILES, THE BRAKE PEDAL SEEMS LOW -- IT TAKES LONGER TO STOP!

I PUT IN A NEW BATTERY AND SOME OF THEM THE MEMORY DOESN'T WORK RIGHT.

TL* THE CONTACT OWNS A 2012 HYUNDAI GENESIS. THE CONTACT STATED THAT THE BRAKE PEDAL TRAVELED TO THE FLOORBOARD WHEN IT WAS DEPRESSED. THE FAILURE OCCURRED SEVERAL TIMES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THERE WAS A CORROSION BUILD UP CONCERNING THE BRAKE FLUID, WHICH AFFECTED THE HYDRAULIC ELECTRONIC CONTROL UNIT. THE MECHANIC REPLACED THE BRAKE PADS AND MASTER CYLINDER, BUT THE BRAKE PEDAL CONTINUED TO TRAVEL TO THE FLOORBOARD. THE DEALER (ALLEN HYUNDAI, 624 E PASS RD, GULFPORT, MS 39507, (228) 539-5555) WAS CONTACTED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE VEHICLE WAS NOT INCLUDED IN NHTSA ACTION NUMBER: PE13033 (SERVICE BRAKES, HYDRAULIC) AND NHTSA CAMPAIGN NUMBER: 13V489000 (SERVICE BRAKES, HYDRAULIC), BUT THE FAILURES WERE SIMILAR. THE MANUFACTURER WAS NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 74,380.

FOLLOWING A HARD TURN WHICH ACTIVATED MY ELECTRONIC STABILITY CONTROL (ESC), I LOST ALL PRESSURE IN MY BRAKE PEDAL AND IT SUNK TO THE FLOOR. THIS IS FOLLOWING A NEAR-ACCIDENT IN WHICH I HAD TO ENGAGE MY ABS SYSTEM BY SLAMMING ON THE BRAKES TO AVOID AN ACCIDENT. EVER SINCE THAT ABS ACTIVATION, MY BRAKE PEDAL HAS NOT FELT THE SAME. IT TAKES MORE EFFORT TO STOP NOW AND YOU HAVE TO PUSH THE PEDAL FARTHER THAN USUAL TO GET BRAKE ACTIVATION. I CAN RECREATE THE PROBLEM BY GETTING THE ESC TO ACTIVATE AGAIN IF I SPIN THE TIRES ON A HARD TURN. IMMEDIATELY AFTER DOING SO, I WILL NO LONGER HAVE ANY BRAKING POWER OR PEDAL PRESSURE. HYUNDAI REFUSES TO ACCEPT RESPONSIBILITY FOR THIS BECAUSE EVEN THOUGH MY VEHICLE IS WITHIN THE AFFECTED PRODUCTION YEARS, THEY CLAIM MY VIN DOES NOT QUALIFY FOR THE RECALL. THE RECALL WAS CAMPAIGN...

WHILE BRAKING AT A STOP LIGHT, THE BRAKE PEDAL WENT TO THE FLOOR AND I LOST ANTI-LOCK FUNCTION AND HAD TO PRESS HARD ON THE PEDAL TO STOP. THE PROBLEM PERSISTED FOR A DAY OR TWO, THEN WENT BACK TO NORMAL. AFTER ABOUT A WEEK, THE SAME PROBLEM OCCURRED. AFTER RESEARCHING THIS ISSUE, I FOUND NUMEROUS CARS HAD THE SAME PROBLEM, YET IT SEEMS HYUNDAI REFUSES TO TAKE RESPONSIBILITY. THERE IS A RECALL NHTSA CAMPAIGN NUMBER: 13V489000, HOWEVER WHEN I RUN MY VIN #, NO RECALLS ARE LISTED. MY CAR IS A 2012 HYUNDAI GENESIS.

THE VEHICLE WAS IN MOTION IN A BUSY COMMERCIAL AREA. WHEN THE BRAKES WERE DEPRESSED THE PEDAL WENT TO THE FLOOR AND SLOWING OF THE VEHICLE WAS IMPAIRED. TO STOP THE VEHICLE REQUIRED PUMPING THE BRAKES TO RETURN SOME PEDAL PRESSURE. THE CAR WAS DRIVEN HOME AND OVER THE COURSE OF SEVERAL STOPS (PUMPING THE BRAKES) THE PEDAL FORCE RETURNED TO NEAR NORMAL. I AM MAKING AN APPOINTMENT TO HAVE THE CAR SERVICED BY A DEALER.

BRAKE PEDAL BEGAN TO REQUIRE MORE AND MORE TRAVEL TO ACHIEVE BRAKING EFFECTIVENESS. THERE WAS NO EVIDENCE OF A BRAKE FLUID LEAK. THERE WAS NO REDUCTION OF BRAKE FLUID IN THE RESERVOIR. THE ABILITY TO MODULATE BRAKING FOR CONDITIONS SUCH AS SLOW SPEED (PARKING LOT) DRIVING IS SIGNIFICANTLY IMPAIRED. THE ISSUE ALSO HAS REQUIRED A VERY HEAVY PRESSURE ON THE BRAKE PEDAL TO ALLOW THE ENGINE TO START (PUSH BUTTON IGNITION SWITCH). I HAVE LEARNED THAT HYUNDAI HAS IDENTIFIED AN ISSUE WITH BRAKE FLUID THAT FAILED TO PROTECT THE HYDRAULIC ELECTRONIC CONTROL UNIT (HECU). RESULTING CORROSION WITHIN THE BRAKE SYSTEM LEADS TO THE FAILURE MODE I AM EXPERIENCING. THIS ISSUE HAS HAPPENED ON A CAR DRIVEN BY AN 86 YEAR OLD WOMAN. THE SITUATION CAME ON OVER TIME, BUT BECAME VERY NOTICEABLE WITHIN THE LAST 6 - 8 MONTHS. THE CAR ONLY HAS 21.4K MILES ON IT.

MY BRAKE PEDAL BECAME SOFT AND SPONGE WITHOUT ANY WARNING SIGNAL. I HAD TO PRESS BRAKE PEDAL ALL THE WAY DOWN TO FLOOR IN ORDER TO STOP AND IT TOOK MUCH LONG DISTANCE TO STOP. HYUNDAI RECALLED MY CAR BACK ON 2013 AND CHANGED BRAKE FLUID. AT THAT TIME I HAD NO BRAKE PROBLEM. I THINK THEY MUST RECALL FOR THIS TERRIBLE MANUFACTURING DEFAULT BEFORE ANYONE GET INTO ACCIDENT.

BRAKE PEDAL GOES TO THE FLOOR WITH VERY LITTLE STOPPING POWER. IN AN EMERGENCY STOP SITUATION, THE CAR WOULD NOT BE ABLE TO STOP TO AVOID AN ACCIDENT.

WHEN APPLYING BRAKES WHETHER ON RESIDENTIAL STREETS, BACKING OUT OF THE GARAGE OR ON THE HIGHWAY THE BRAKE PEDDLE CONTINUES TO SINK TO THE FLOOR AND ONLY PROVIDES VERY LITTLE STOPPING POWER (SOMETHING LIKE A COASTING STOP). SINCE THIS RECENTLY STARTED HAPPENING I HAVE DISCOVERED THAT PUMPING THE BRAKES HELPS TO GET BETTER STOPPING RESULTS BUT IT IS NOW SCARY TO DRIVE. I HAD THE BRAKE FLUID REPLACED AS A RESULT OF HYUNDAI'S CAMPAIGN 114 RECALL IN JULY OF 2014, HOWEVER I AM NOW EXPERIENCING WHAT APPEARS TO BE CONSISTENT BRAKE FAILURE. I HAVE CONTACTED HYUNDAI CONSUMER AFFAIRS AND THEY BASICALLY STATED THAT BECAUSE I HAD THE CAMPAIGN 114 RECALL DONE THAT THERE IS NOTHING ELSE THEY CAN DO REGARDING THE POSSIBLE HECU MODULE FAILURE AS A RESULT OF DETERIORATION DUE TO THE DOT-3 BRAKE FLUID EXPOSURE. I ALSO FIND IT HARD TO ACCEPT THAT THE HECU MODULE WAS TAKEN...

HYUNDAI ISSUED A TECHNICAL SERVICE BULLETIN FOR THE BH GENESIS SEDAN HECU INSPECTION AND BRAKE FLUID REPLACEMENT (RECALL 114). THE DEALER TOLD ME THIS SERVICE WAS PERFORMED ON MY CAR IN 2014. MY HECU HAS FAILED AND BRAKING IS VERY LIMITED. IT APPEARS THAT THE RESOLUTION TO THIS RECALL DOES NOT RESOLVE THE PROBLEM. MY CAR IS NOT SAFE TO DRIVE. SHOULD THE RECALL BE ISSUED AGAIN REQUIRING REPLACEMENT OF THE HECU?

AFTER DRIVING STEADILY AT 35-40 WITHOUT BRAKING, APPLIED BRAKES APPROACHING CARS STOPPED A LIGHT. THE BRAKE PEDAL WENT NEARLY TO THE FLOOR AND THE CAR ONLY SLOWED MINIMALLY. AFTER SEVERAL PUMPS, BRAKING RETURNED AND I WAS ABLE TO STOP BEFORE COLLIDING WITH THE STOPPED TRAFFIC. AFTER THAT, THE CAR BRAKED NORMALLY. THIS WAS THE 2ND TIME THIS HAPPENED, THE FIRST TIME BEING JUST A FEW DAYS EARLIER. THE INITIAL EPISODE WAS LESS DRAMATIC. THERE WERE NO WARNING LIGHTS BEFORE OR AFTER THE EVENT. THE CAR IS AT THE DEALER FOR SERVICE NOW. THIS WAS INCREDIBLY SCARY; I COULD HAVE PUSHED THE CAR IN FRONT OF ME THROUGH THE INTERSECTION INTO 60MPH HIGHWAY TRAFFIC. THE BRAKE FLUID HAD BEEN REPLACED UNDER A TSB AT 6,502 MILES DUE TO CORROSION ISSUES RELATED TO THE HYDRAULIC ELECTRONIC CONTROL UNIT (HECU). IT'S FRIGHTENING TO THINK THIS PROBLEM MAY BE RESPONSIBLE FOR A SERIOUS BRAKE...

BRAKE PEDAL WANTS TO GO TO THE FLOOR NEARLY AT TIMES, BEFORE THE CAR BEGINS TO STOP, WITH LESS THAN 48,000 MILES ON THE CAR. ISSUE JUST STARTED DOING THIS, RIGHT AFTER MY LAST SERVICE APPOINTMENT, WHERE I WAS ADVISED THAT MY FRONT BRAKES NEEDED TO BE REPLACED AND THAT MY WARRANTY HAD ENDED A MONTH EARLIER. THIS PROBLEM POINTS TO A POSSIBLE $2600 HECU UNIT PROBLEM. AMAZING HOW THIS STARTED RIGHT AFTER I HAD SERVICE PERFORMED. PLEASE INVESTIGATE AND HAVE ALL 2012 HYUNDAI GENESIS VEHICLES RECALLED TO HAVE THE BRAKE FLUID CHANGED, NEW BRAKE BOOSTER, AND THE HECU MODULE REPLACED AT THE SAME TIME, BEFORE SOMEONE GETS KILLED.

THE HYDRAULIC ELECTRONIC CONTROL UNIT (HECU) IN MY VEHICLE NEEDS TO BE REPLACED PER THE HYUNDAI DEALERSHIP SERVICE DEPARTMENT, AT A COST OF $2600 ($1900 PART/$700 LABOR). THE BRAKE PEDAL PRESSES ALL THE WAY TO THE FLOOR AND DOES NOT STOP THE VEHICLE RELIABLY, NEARLY RESULTING IN ACCIDENTS ON MORE THAN ONE OCCASION. THE CAR IS NO LONGER SAFE TO DRIVE. I HAVE READ COUNTLESS COMPLAINTS IN HYUNDAI GENESIS OWNER FORUMS REGARDING THE FAILURE OF THESE HECU MODULES IN 2009-2012 MODELS, WHICH HYUNDAI HAS CLEARLY BEEN AWARE OF SINCE 2013, BUT AS FAR AS I CAN TELL, HAS DONE NOTHING TO ADEQUATELY RESOLVE. THIS IS A SERIOUS PROBLEM THAT AFFECTS THE SAFETY OF THE OWNER AND THEIR FAMILIES, AND IT SEEMS OUTRIGHT CRIMINAL THAT HYUNDAI HAS NOT BEEN FORCED TO REPLACE THESE HECU MODULES ON EVERY MODEL PRODUCED WITH THESE FAILING PARTS. NHTSA CAMPAIGN 13V489000 ADDRESSING THE INTERNAL CORROSION OF...

I WAS DRIVING TO MY WORK. I SAW RED LIGHT SIGNAL AND STEPPED ON BRAKE PEDAL. BUT THE PEDAL JUST WENT DOWN VERY SOFTLY WITHOUT STOPPING MY CAR. MY CAR STOPPED AFTER I PRESSED FULL FORCE ON BRAKE PEDAL. BY THE TIME MY CAR STOPPED IT ALREADY PASSED 15 FEET FROM THE STOP LINE WHERE I HAD TO STOP.

TROUBLE WITH PUSHING DOWN HARD ON THE BRAKE PEDAL AND CONCERNED WITH BRAKE EFFECTIVENESS. AND SAFETY. FORCED TO PUSH BRAKE ALL THE WAY TO THE FLOOR IN ORDER TO STOP.

INTERMITTENT BRAKE FAILURES. SEEMS THERE HAS BEEN A RECALL FOR BAD BRAKE FLUID ON THIS MODEL YEAR HYUNDAI GENESIS SEDAN. HYUNDAI WOULD NOT COVER THIS VEHICLE UNDER THE RECALL WHEN CONTACTED. THE VEHICLE HAS AN INTERMITTENT SOFT BRAKE PEDAL WHICH GOES ALL THE WAY TO THE FLOOR UNDER HARD AND SOFT BRAKING CONDITIONS, WHETHER MOVING FAST OR SLOW AND IN ALL WEATHER CONDITIONS. THE BRAKE PADS AND ALL 4 ROTORS ARE IN GOOD REPAIR. THERE IS NO AIR IN THE BRAKE LINES. IT APPEARS TO BE THE ABS MODULE THAT IS FAILING AND CAUSING UNSAFE BRAKING CONDITIONS WITHOUT WARNING. THERE ARE NUMEROUS ONLINE FORUM COMPLAINTS ABOUT THIS MODULE WHICH SEEMS TO BE A FAULT IN DESIGN BY HYUNDAI. MY HOPE IS THAT NHTSA CAN INFORM OTHER OWNERS OF THIS MODEL YEAR THAT UNSAFE BRAKING CONDITIONS CAN HAPPEN AT ANY TIME FROM FAILURE OF THIS ABS MODULE. *TR

SPORADICALLY THE BRAKE PEDAL GOES ALL THE WAY TO FLOOR. PEDAL HAS TO BE PUMPED 2-3 TIMES BEFORE BRAKES ENGAGE. THIS HAS HAPPENED ON 3 DRIVING OCCASIONS OVER 10 DAYS. TOOK IT TO DEALER THIS MORNING WHO SAID UNLESS HE COULD REPLICATE ISSUE, HE WILL NOT REPAIR DESPITE PRIOR RECALL FOR SAME ISSUE. YESTERDAY ON PHONE, HE SAID HE WOULD INSPECT AND FILE CLAIM WITH HYUNDAI. APPARENTLY BRAKE FLUID WAS REPLACED IN 2013 DUE TO RECALL BY PRIOR OWNER. NOW SAME THING IS HAPPENING. PROBLEM OCCURS UNTIL ENGINE IS TURNED OFF. 3 TIMES IN 10 DAYS IS FRIGHTENING. FORTUNATELY, I WAS FAR ENOUGH BEHIND CAR IN FRONT TO HAVE TIME TO PUMP BRAKES. *TR

I WAS DRIVING AND WENT OVER A SLIPPERY AREA AT AROUND 40 MPH IN THE CITY WHILE BRAKING AND MY BRAKES WENT DOWN TO THE FLOOR. THERE WAS NO CAR IN FRONT OF ME SO I WAS ABLE TO SLOWLY COME TO A STOP. HOWEVER, SINCE THEN MY BRAKES HAVE NOT BEEN FUNCTIONING PROPERLY, THEY SLOWLY GO DOWN TO THE FLOOR UNDER ANY BRAKING CONDITION. AND WHEN I STOP AT A STOP LIGHT THE PEDAL CONTINUES TO DEPRESS UNTIL IT'S AT THE FLOOR. IN THE PAST I HAD THIS ISSUE WHEN I WENT OVER A LARGE DIP WHILE BRAKING. HOWEVER IT RESET ITSELF SHORTLY AFTER AND I DIDN'T HAVE THE ISSUE AGAIN UNTIL TODAY. MY CAR WAS PART OF THE LARGE RECALL FOR THE GENESIS IN WHICH THE BRAKE FLUID WAS REPLACED. *TR

TL* THE CONTACT OWNS A 2012 HYUNDAI GENESIS. WHILE DRIVING APPROXIMATELY 25 MPH, THE BRAKE PEDAL WAS DEPRESSED AND TRAVELED TO THE FLOORBOARD. THE CONTACT COASTED TO THE SIDE OF THE ROAD TO A COMPLETE STOP. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, BUT THE FAILURE COULD NOT BE DIAGNOSED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 87,000.

MY WIFE AND I HAVE A 2012 HYUNDAI GENESIS 3.8 SEDAN. MY WIFE IS THE PRIMARY DRIVER. SHE CAME HOME ONE EVENING AND TOLD ME THAT THE CAR FAILED TO STOP AND WENT INTO THE INTERSECTION AS SHE ATTEMPTED TO STOP FOR A RED TRAFFIC SIGNAL. I IMMEDIATELY DROVE THE CAR DOWN THE STREET AND OBSERVED THAT YOU HAD TO PUMP THE BRAKES TO STOP AND THE PEDAL WENT TO THE FLOOR. I ADDED SOME BRAKE FLUID AND PUMPED THE BRAKES. I DROVE THE CARE THE NEXT FEW DAYS AND NOTICED THAT OVER TIME THE SAME THING HAPPENED WITH THE PEDAL GOING TO THE FLOOR. I TOOK THE CAR TO MY MECHANIC AND HAD ALL THE BRAKES CHANGED. THAT COST ME OVER $320.00. THE MECHANIC ADVISED ME THAT THE CAR HAD A FAULTY MASTER CYLINDER. TO SHORTEN THE STORY. DUE TO THE DEALER COST OF FROM $275.00 TO $365.00 FOR...

WHEN DRIVING ON FREEWAY AT 65MPH THE ENGINE MISSED THEN STALLED. I LOST POWER STEERING AND POWER BRAKES. MULTIPLE WARNING LIGHTS ON. DEALER IS NOT FINDING ANYTHING USING COMPUTER DIAGNOSTICS. LOSS OF STEERING AND BRAKES AT HIGH SPEEDS IS NOT GOOD!!!!
