   On August, 2nd around noon, I was driving alone, west on a rural road called 1869 in Liberty Hill, TX. I believe the speed limit on this winding rural road is 55mph, and I was about 1 mile west of 183. While my car was in motion, my active headrest activated (exploded) into the back of my head, throwing me forward into the steering wheel. This happened randomly and unprompted. There were no other cars on the road with me, I didn’t collide with anything, and the road was smooth. I quickly regained control of the car and continued to my destination. The Hyundai dealership confirms the misfired active headrest, and Hyundai does not want to repair it, as the vehicle is out of warranty. There were no warnings prior to the event. I was resting my head on the headrest when it happened.

   Within last two years I've been dealing with random and intermittent headlight flickering/turning off when the light stalk switch is in AUTO mode. Also, the cabin lights flicker and turn off at the same time when headlights do. It is very dangerous when it happens during night driving. Luckily problem can be overridden by switching the stalk to ON modes and the interior cluster lights and headlights come back on again. Problem seems to be happening only when in AUTO mode. I talked to dealer, they tried to replicate the problem without success. Problem happens to me at least once a month. I spent lot of time reading about this problem in forums, and found one same comment on the Equus vehicle and many on Genesis which was sold in much higher volumes. It seems to be the same problem, and Hyundai has issued the extended warranty program (but for Genesis 15-16 cars) 20-BE-009H. I firmly believe it's the same problem, its just not many Equus vehicles was sold as Genesis. Please help - we are hardly driving the car at night anymore and we really like it. And dealer didn't want to replace the stalk without being able to properly diagnose/replicate the problem.

   Active headrest on front passenger side inadvertently deployed while driving on a smooth toll road at normal speed. Any passenger could have been severely injured and there could be risk of driver side deployment that could not only cause severe injury but also collision. There were no warning indicators and the entire unit must be replaced because the plastic retention clips broke. The car is currently in the shop.

   WHENEVER IT GETS HOT IN THIS AREA, MY VEHICLE MALFUNCTIONS. FIRST THE DASH BUBBLED AND HAD TO BE REPLACED. THE LEATHER ON THE DRIVER DOOR BUBBLES UP AND HAS BEEN REPLACED.. IT IS BUBBLING AGAIN ON THE DRIVER DOOR BUT IS NOT COVERED BY THE EXTENDED WARRANTY. BOTH HEADRESTS HAVE POPPED OPEN. ONE HAPPEN WHILE AT THE CAR WASH AND THE OTHER HAPPENED WHILE I WAS IN THE GROCERY STORE. BOTH TIMES THE CAR WAS AT REST AND WINDOWS UP.. IT COSTS $1600 TO REPLACE. THE DRIVER WINDOW SWITCH DOES NOT WORK WHEN HOT OUTSIDE. HAD IT CHECKED BY THE DEALERSHIP AT LEAST 10 TIMES. MAINTENANCE AGENT WITNESSED IT BUT BY APPOINTMENT TIME WAS NOT ABLE TO DUPLICATE THE PROBLEM SO THE WARRANTY REPAIR NEVER OCCURRED. ADDITIONALLY,, THE RADIO GOES OUT AND FRIES LIKE A CB. COMPLAINED TWO YEARS ABOUT THIS ISSUE BUT AGAIN, THE MECHANIC COULD NEVER DUPLICATE THIS ISSUE WHEN THE CAR WAS RETURNED FOR AN APPOINTMENT. ALL EXCEPT FOR 3 TIMES THE MECHANIC WITNESSED THE PROBLEM AND SHOWED ME HOW TO RESET THE RADIO. THIS ISSUED OCCURRED WHEN CAR WAS IN MOTION AND ABOUT 50% OF THE TIME WHEN THE PHONE WAS CONNECTED AND IN USE. I HAVE TO PUSH A HOLE WITH A PEN TIP TO RESET IT ONCE A MONTH. EVENTUALLY,, I COMPLAINED TO GM AND THEY HAD RADIO REPLACED BUT DEALERSHIP PUT IN A DIFFERENT MODEL OTHER THAN THE ONE FOR THE CAR. NOW PHONE SYSTEM HAS TO BE REPROGRAMMED FOR USE WHENEVER I ENTER THE CAR AS WELL AS THE RADIO SYSTEM RANDOMLY CHANGES THE STATION WHEN TRAVELING. I HAVE VIDEO OF THIS ISSUE. LASTLY THE WINDOWS GET STUCK IN THE UP POSITION WHEN IT IS HOT OUTSIDE. HAD THEM CHECKED BY MAINTENANCE MANAGER, BUT HE COULD NOT DUPLICATE THE ISSUE DURING THE APPOINTMENT . PROBLEM STILL EXISTS.

   MAY 4TH 2019 VEHICLE FOUND DEAD AND WOULD NOT START. NO SIGNS OF ANY BATTERY ISSUES IN THE PAST FEW DAYS. THE VEHICLE WAS TOWED DIRECTLY TO THE SERVICE DEPARTMENT AT EMPIRE HYUNDAI LOCATED IN FALL RIVER, MA. VEHICLE CONFIRMED BY SERVICE DEPARTMENT TO TURN OVER, HOWEVER NO LIGHTS OR CLOCK AND NO POWER. THEN ALL WENT DEAD FOR THE SERVICE DEPARTMENT. SERVICE MANAGER INFORMED THAT HE WAS NOT ABLE TO PROVIDE THE ROOT CAUSE FOR THE ONGOING ELECTRICAL ISSUE, AND THE SPECIFIC CAUSE OF THIS INCIDENT. THE SOLUTION THAT WAS PROVIDED WAS TO INSTALL A NEW REPLACEMENT BATTERY. WHEN THE BATTERY WAS INSTALLED, THE 'ISSUE' SEEMED TO GO AWAY. THIS IS A RE-OCCURRING ISSUE RELATED TO THE ELECTRICAL HARNESS, AND THAT IT IS UNLIKELY THAT REPLACING BATTERY IS THE SOLUTION TO THE PROBLEM. EMPIRE'S SERVICE DEPARTMENT HAS DOCUMENTED THE ONGOING ELECTRICAL ISSUES AS THE CAR HAS BEEN BROUGHT IN NUMEROUS TIMES USUALLY 'SHUTTING OFF 'AT HIGHWAY SPEEDS WITH THE WHEELS LOCKING UP. (5 TIMES). WE WERE TOLD IT WAS A GROUND ISSUE AND A 'NEW GROUND BOLT WAS INSTALLED, HOWEVER THE VEHICLE CONTINUED TO 'SHUT OFF AT HIGHWAY SPEEDS 'AND THE VEHICLE IS VERY HARD TO CONTROL AS LOSS OF POWER STEERING AND BRAKING OCCURS. WHEN THIS HAPPENS AND IS DANGEROUS AND CAUSE AN ACCIDENT WITH OTHER CARS OR OBJECTS DUE TO LOSS OF CONTROL. THIS IS CLEARLY RELATED TO THE WIRING HARNESS\GROUND BOLT AND THE FAILURE MODE IS SIMILAR TO PREVIOUS INCIDENTS WHEN THE VEHICLE FAILED DURING OPERATION . COMMUNICATED WE DID NOT FEEL SAFE CONTINUING TO OPERATE THIS VEHICLE WITH THIS ISSUE UNRESOLVED. CASE # 15744270 W/ HYUNDAI COMPLAINT DEPT. ATTN: THERE ARE PREVIOUS COMPLAINTS IN NHTSB DATABASE FROM OTHER EQUUS USERS THAT HAVE EXPERIENCED THE LOSS OF POWER WHILE VEHICLE IS UNDER OPERATION. THE RISK WITH THIS FAILURE MODE IS SERIOUS INJURY OR DEATH AND SHOULD BE ASSIGNED YOUR HIGHEST SEVERITY RISK RATING.

   ON SEVERAL OCCASIONS WHILE DRIVING WITH THE CRUISE CONTROL ENGAGED, AS I APPROACH A VEHICLE FROM THE REAR THAT IS GOING SLOWER, THE AUTOMATIC BRAKING SYSTEM ENGAGES AND DISPLAYS A MESSAGE SIMILAR TO THIS! " SHUT DOWN ENGINE IMMEDIATELY, SERVICE REQUIRED." THE FIRST TIME IT HAPPENED, I DID SO, AND HAD THE CAR TOWED TO A DEALERSHIP. THEY SAID THEY COULD NOT FIND ANYTHING WRONG. I'VE REPORTED THIS PROBLEM TO THE DEALERSHIP THAT REGULARLY SERVICES THE CAR, AND THEY SAY THEY CAN'T RECREATE THE CONDITION. IT APPEARS TO BE A SOFTWARE PROBLEM. ON SEVERAL OCCASIONS RECENTLY WHEN THIS CONDITION APPEARS, THE ABILITY TO RESUME ACCELERATION IS LOST MOMENTARILY, AND THE CAR SLOWS DOWN DRASTICALLY. IT SUDDENLY RELENTS, AND RESUMES TRAVELLING AT THE PRESET SPEED. THIS ALWAYS HAPPENS ON MAJOR HIGHWAYS WHERE CRUISE CONTROL IS ENGAGED. I'M VERY CONCERNED THAT ONE DAY THE WARNING MAY LEAD TO A CATASROPHIC FAILURE OF THE ENGINE
