LANE DEPARTURE: ASSIST, LANE DEPARTURE: LANE KEEP: AUTOMATIC STEERING
The driver seat belt pops out sometimes for reasons unknown. The speakers suddenly stop working at random times so I got lost while listening for navigation directions safely paying attention to the road instead of watching the screen for upcoming turns. And the biggest one, a few times I almost crashed into oncoming cars and guard rails because if the road has a dip the sonata decides to jerk hard to the side and overcorrect itself when lane assist is on. When the road is level it just beeps annoyingly loudly when it can't see the lines or you accidentally cross over it, but does not actively assist even tho active lane assist is on. This is a major safety issue!!!!!

The automatic shut off. When the car is locked I can run it for a total of 20 minutes with auto start, when it's unlocked I can run it for a total of 60 minutes. Sometimes because of my job I need to auto start it and run it for longer to either warm up or cool down and it is unsafe to leave it unlocked. There should be an option for me to turn off the time limit and not have it reset every time I restart the car! When I'm shopping and I need to leave my dog inside for instance and it's 91 degrees outside, I should be able to lock my car and let it run for as long as I need to be in the store without worry it will shut off with him inside and suffocate him in the heat. This is another HUGE safety issue!

POWER TRAIN
The transmission since we got the vehicle has had random hard shifts. The software updates seemed to have alleviate some of the occurrences. How ever when it does happen now. The whole car shakes while at idle and shifts extremely hard. Almost like braking hard. The problem has not been reproduced at a dealership yet, taking it in ASAP for inspection. Noting relating to the power train has been replaced. Just a software update a while back. No warning lights came on the screen when it happened. My wife was going about 20 miles per hour when she tried to accelerate. It was hesitant than shifted hard, lurching forward than accelerated. When she came to a stop at the next light it was shaking the whole car.

ELECTRICAL SYSTEM, ENGINE, VEHICLE SPEED CONTROL
Driving, car started making a weird sound followed by a warning light on dashboard with dinging sound to correlate... car became difficult to gas, vehicle motion was lagging where I just knew I had to pull over Bc this car was going to literally stop began to slowly (Bc that’s all car would allow) to proceed forward and I was forced to come to a haunt as I pulled onto side of highway. I then could no longer move it. Turned car off for minute then returned to try to start again, car would not accelerate at all nor turn on fully.. I was forced to wait hour to get a tow... took to shop, no problem such was found , car started & ran again ... this is 3 days later the car again continued the same exact pattern & I was unable to drive any further and forced to once again to get tow. This has to be something of bearings with engine, this car mode is not on list but IT certainly is an issue that I believe is related & should be rectified by Hyundai.

STEERING, WHEELS
DRIVING ON DRY ROAD, IN MIDDLE LANE OF THREE LANES GOING 65 MPH. SUDDENLY, RIGHT REAR TIRE "POOFED" BUT I KEPT CONTROL, STARTED TO LOOK RIGHT TO GET OFF ROAD. TOOK FOOT OFF GAS, DID NOT PUT ON BRAKE. SUDDENLY, LEFT REAR "POOFED" AND THEN AN EXTREMELY LOUD-METAL ON METAL- SOUND OCCURRED BACK LEFT AND MY CAR JACK KNIFED INTO THE PASSING , FAST LANE. A DUMP TRUCK TRAVELING IN THAT LANE STRUCK ME, FRONT END AND MY DOOR. THE TRUCK HIT ME AND I ROLLED INTO THE GRASSY MEDIUM, ROLLING OVER SEVERAL TIMES. THE SAFETY DEVICES WORKED FABULOUSLY AND MY ONLY INJURIES WERE FROM THE SEAT BELTS WHICH SAVED MY LIFE. I AM LUCKY TO BE ALIVE AND I HOPE THIS DOESN'T HAPPEN TO SOMEONE ELSE. I WAS IN ICU FOR 5 DAYS AND HOSPITAL FOR A TOTAL OF 9 DAYS, I AM WILL BE RECOVERING AT HOME FOR MONTHS. I WOULD LIKE IT INVESTIGATED THAT EITHER A MECHANICAL ISSUE OR TIRE ISSUE CAUSED THE ACCIDENT. I ONLY HAD 2300 MILES ON THE CAR.*DT*JB

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
THE VEHICLE'S FUEL GAUGE (TYPE C) DOES NOT ACCURATELY ADJUST FOR CHANGES IN THE AMOUNT OF GAS IN A TIMELY MANNER. IT NORMALLY TAKES 2-3 DAYS FOR THE GAUGE TO MOVE TO FULL TANK EVEN THOUGH IT IS FULL. SAME PROBLEM FROM 1/4 TO 1/2 TANK, ETC. FOR EXAMPLE, I NOTICED THE PANEL SAID I HAD 11 MILES TO EMPTY ON FRIDAY. THE GAS GAUGE SHOWED OTHERWISE. I WASN'T NEAR MY USUAL FILL STATION, SO I PUT 5 GALLONS OF GAS IN THE CAR. IT IS NOW WEDNESDAY (5 DAYS LATER). THE GAS GAUGE MOVED SLIGHTLY YESTERDAY TO ALMOST 1/4 TANK, BUT THE FUEL TANK WARNING WENT FROM 11 TO 0 MILES LEFT TO EMPTY (SEE ATTACHMENT). I DROVE ON THE HIGHWAY EACH DAY AND IN THE CITY. I PURCHASED THIS CAR JULY 2020 WITH A FULL TANK. THIS PROBLEM BECAME EVIDENT IN AUG 2020. AFTER REFILLING THE TANK, THE READER SHOWED 111 MILES TO EMPTY. I INFORMED HYUNDAI AGENT OF THE ISSUE, WHO HAD NO IDEA WHY THIS WAS HAPPENING. THE GUAGE AND FUEL TANK READER FINALLY ADJUSTED AFTER ABOUT 3 DAYS. I HAD 449 MILES ON THE CAR AT THAT TIME. I NOW HAVE OVER 4,000 WITH SAME PROBLEM. APPARENTLY, SOMETHING IS FAULTY, BUT I DON'T KNOW WHAT. AUTO DEALER IS BAFFLED. THIS ISSUE COULD RESULT IN A REAL FUEL SHORTAGE WHILE TRAVELING WITH NO GAS STATION NEARBY.

ENGINE
ON NOV. 17 WHILE DRIVING APP. 65 MPH ON THE HIGHWAY THE CAR SUDDENLY SHUT ITSELF OFF. ALL OF THE DASHBOARD LIGHTS LIT UP & THE CAR WOULD NOT RESTART. AFTER 10 MIN. OF TRYING TO RESTART THE CAR, THE CAR STARTED AGAIN, & ALL THE LIGHTS ON THE CAR DISAPPEARED. THE FOLLOWING DAY, WHILE WAITING IN THE TURNING LANE AT A RED LIGHT, THE CAR SPUTTERED & TURNED OFF. ALL THE LIGHTS ON THE DASHBOARD LIT UP & THE CAR WOULDN'T START I HAD THE CAR TOWED ON NOV 18 202 TO A HYUNDAI DEALERSHIP. THE DEALERSHIP REPORTED THAT THERE WAS AN INTERNAL SHORT WITH THE ABS MODULE & THE HYDRAULIC MODULE ASSEMBLY WAS REPLACED. ON, NOV 24, I WAS DRIVING THE CAR & THE CAR STALLED ALL THE WARNING LIGHTS WENT BACK ON. I HAD THE CAR TOWED THE DEALERSHIP WHERE IT STAYED UNTIL DECEMBER 11 THE DEALERSHIP STATED THAT THEY COULD NOT FIND ANYTHING WRONG WITH THE CAR. I PICKED UP THE CAR ON DEC 11 & THE CAR APPEARED TO BE WORKING NORMALLY. HOWEVER, ON DEC19, WHILE STOPPED AT A RED LIGHT, THE CAR BEGAN TO SHAKE BACK & FORTH AT IDLE & THE RPMS STARTED TO GO UP DESPITE MY FOOT BEING ON THE BRAKES. THE CAR BEHIND ME SAW WHAT WAS HAPPENING & HELPED ME PULL OVER TO THE SIDE OF THE ROAD. I HAD THE CAR TOWED TO THE DEALERSHIP YET AGAIN. THE DEALERSHIP STATED THAT THEY WERE ABLE TO DUPLICATE THE ISSUE ON DEC 23, 2020. HOWEVER, NO FIX WAS DONE TO THE CAR. THE DEALERSHIP CLAIMED THAT THE CAR WAS IN A 'RELEARN' PROCESS & IT WOULD NEED MORE TIME FOR THE CAR TO 'RELEARN' HOW TO DRIVE AGAIN. EVERYTHING SEEMED OKAY AFTER THE DEC 23 INCIDENT UNTIL FEB 8 2021 WHEN I TRIED TO STOP WHILE IN TRAFFIC & THE BRAKES WOULD NOT WORK AT ALL. I NARROWLY AVOIDED GETTING INTO A MAJOR ACCIDENT & ONCE AGAIN BROUGHT THE CAR TO THE DEALERSHIP. THE DEALERSHIP FOUND THAT THE MASTER CYLINDER ASSEMBLY WAS INTERNALLY DEFECTIVE & WAS NOT HOLDING PRESSURE AND AS A RESULT THE BRAKES WERE NOT WORKING. THE VEHICLE WAS RETURNED TO ME ON FEB 11 2021.

OCCASIONALLY THERE IS A SERIOUS DELAY WHEN TRYING TO ACCELERATE. CAR TENDS TO JERK/BUCK WHEN ACCELERATING, USUALLY IN THE LOWER GEARS. I HAVE NO IDEA IF THIS IS A TRANSMISSION ISSUE OR A FUEL INJECTION ISSUE, BUT MY DEALERSHIP HAS NOT BEEN ABLE TO DETECT AN ISSUE AND KEEPS TELLING ME EVERYTHING IS NORMAL WHEN IT CLEARLY ISN'T. THE CAR ALSO HAS HARSH DOWNSHIFTS ESPECIALLY GOING FROM 2ND TO 1ST GEAR.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: ASSIST
GASES FROM THE DASHBOARD HEATING CAUSE A FILM TO FORM BETWEEN THE WINDSHIELD AND THE CAMERA. BECAUSE OF THIS, IN HEAVY DIRECT SUNLIGHT, LANE KEEP ASSIST TOGGLES ON AND OFF WITHOUT WARNING CAUSING UNINTENDED LANE DEPARTURES WITH OUT WARNING. ALSO, WHEN USING SMART CRUISE CONTROL, THE VEHICLE SLOWS TO A STOP BUT MAY CONTINUE MOVING SLOWLY EVEN AFTER DISPLAYING THE PRESS GAS TO CONTINUE SCREEN. THE AUTO HOLD LIGHT DOES NOT ILLUMINATE.

WHEELS
ON AUGUST 14TH,2020, I PURCHASED A VEHICLE FROM THE SHOWROOM FLOOR FROM CRAIN HYUNDAI OF CONWAY, ARKANSAS. THE CAR WAS AESTHETICALLY PLEASING AND ONLY HAD 46 MILES ON THE SPEEDOMETER. AT THE TIME OF THE PURCHASE I WAS NOT AWARE OF THE TERM "MODIFICATION" NOR THE RAMIFICATION ASSOCIATED WITH HAVING A VEHICLE MODIFIED. I ASSUMED THE DEALERSHIP WERE RESPONSIBLE FOR PROVIDING ME WITH A SAFE AND EFFICIENT VEHICLE. THE CAR HAD ADDED EQUIPMENT: CRAIN CARE PKG: $1,397.00 - WHEEL LOCKS: $89.00 - WINDOW TINT: $189.00 - BLACK OUT PACKAGE: $4,295.00, WHICH I LATER LEARNED THE AMERICAN RACING RIM #AR934 FASTLANE, DOES NOT FIT A 2020 HYUNDAI SONATA, THEY ARE 20 INCH RIMS AND HAD EXTENSA HP 225/35R20 90W TIRES AND THE RECOMMENDED TIRE IS 235/45R18. WITHIN A MONTH AFTER THE NEW CAR PURCHASE IT RAIN AND THE CAR LOST TRACTION AND BEGAN TO SLIP AND SLIDE. I PROPOSE IMPLEMENTING LAWS TO GOVERN DEALERSHIP MODIFICATION OF VEHICLES AND HOLD SAID DEALERSHIP RESPONSIBLE FOR INFORMING THE CONSUMER OF THE NEGATIVE RAMIFICATIONS INVOLVED WITH KNOWINGLY PURCHASING A VEHICLE FOR AESTHETIC DESIRES. AFTER LEARNING OF MY MISTAKE THE HYUNDAI CORPORATION WOULD NOT NEGOTIATE A REASONABLE AGREEMENT WITH ME, AND CLOSED THE COMPLAINT LEAVING ME WITH AN UNSAFE VEHICLE THAT WAS ALTERED BY A THIRD PARTY COMPANY WITHIN THE DEALERSHIP, NAME: MOTOR SPORTS AUTHORITY. THE DEALERSHIP WOULD NOT RELEASE FROM THAT CONTRACT AND THE WORKMANSHIP OF THE BLACK OUT PACKAGE IS UNRAVELLING AND I DISCOVERED THE MODIFICATION HAS DECREASE THE VALUE OF THE CAR, WHEN I THOUGHT IT WOULD INCREASE IN VALUE. I ALSO LEARN THE ADDED EQUIPMENT STATED ABOVE WAS NOT INCLUDED ON THE VEHICLE PURCHASE INVOICE WHICH EFFECTS POSSIBLE REPAIRS AND/OR REPLACEMENT CONCERNING AUTOMOBILE INSURANCE COVERAGE. DEALERSHIP SHOULD BE HELD ACCOUNTABLE AND RESPONSIBLE FOR INFORMING CUSTOMERS OF MODIFICATION AND BE HELD LEGALLY BINDING FOR THE VEHICLE SAFETY

ELECTRICAL SYSTEM, POWER TRAIN
FOLLOWING A FIRMWARE UPDATE TO THE OBC FOR A RECALL, THE VEHICLE TRANSMISSION NOW HAS A SEVERE DELAY RESPONDING TO DRIVER INPUT. THE TRANSMISSION IN THIS VEHICLE HAS ELECTRONIC SHIFT WITH PUSHBUTTONS. PREVIOUS TO THE FIRMWARE UPDATE, THE TRANSMISSION WOULD RESPOND INSTANTLY TO DRIVER INPUT FROM THESE BUTTONS. FOLLOWING THE FIRMWARE UPDATE, THE TRANSMISSION TAKES TWO SECONDS TO RESPOND. THIS DELAYED ACTION PROHIBITS DRIVER EMERGENCY SHIFTING, CREATING SEVERE RISK OF AN ACCIDENT. IN MY VEHICLE, I RECENTLY WAS ALMOST INVOLVED IN A TRAFFIC ACCIDENT WHEN THE DELAYED RESPONSE FROM THE TRANSMISSION CAUSED MY VEHICLE TO REVERSE INTO THE OPPOSING LANE OF TRAFFIC AS ACCELERATION WAS ATTEMPTED THINKING THE VEHICLE HAD SHIFTED INTO DRIVE. UPON ENTERING THE ACTIVE OPPOSITE LANE OF TRAFFIC, EMERGENCY ACCIDENT AVOIDANCE WAS PROHIBITED BY THE DELAYED RESPONSE OF THE VEHICLE SHIFTING INTO 'DRIVE' IN ORDER TO MOVE THE VEHICLE FROM THE OPPOSITE LANE OF TRAFFIC. PREVIOUS TO THIS INSTANCE, THERE HAVE BEEN DELAYS IN VEHICLE SHIFTING WHICH HAVE NEARLY CAUSED AN ACCIDENT WHEN THE DRIVER ATTEMPTS TO PLACE THE VEHICLE IN 'PARK', BUT THE DELAY CAUSES THE VEHICLE TO MOVE FORWARD AS THE DRIVER REMOVES THEIR FOOT FROM THE BRAKE, AND THE CAR MOVES FORWARD TOWARD STATIONARY OBJECTS AND PEOPLE. THIS HAS BEEN REPORTED TO HYUNDAI AND THEY HAVE NOT RESPONDED YET. FURTHERMORE, OTHER OBVIOUS FIRMWARE ISSUES IN THE VEHICLE HAVE BEEN IDENTIFIED, ONE IN A DIFFERENT SAFETY SYSTEM.
