The Emergency brake light, ABS light, and esc light all come on while driving & speedometer goes to 0. The speedometer also stops tracking mileage when these lights come on. This used to happen on & off, but now it’s almost permanent. Hundreds are reporting the same exact issue online, but mechanics cannot figure out what the problem is. Me and countless others have taken the vehicle to mechanics multiple times with no resolve and thousands of dollars worth of diagnostics that are incorrect and don’t resolve the issue. It is dangerous because we don’t know how fast we’re going, and we don’t know if your abs, emergency brakes, & esc are all working properly. This issue is impacting Hyundai Accents years 2015, 2016, & 2017 based on the multiple threads & posts online. I think it’s related to electrical issues too because my windshield wipers & blinkers will randomly malfunction while this is happening. A random online user said that it is a “SMART Junction Box” issue that needs to be replaced. Please look into this and issue a recall because thousands of people are spending thousands of hard-earned dollars with no resolve.

I Dont no why but my Engine will randomly stall out even in the middle of making a.left or a right-hand turn and it's scary when I a.m. at an intersection intersection and I doll out then I have to shut my car off completely turn it back on and pump the gas. Till it starts . few days later my warning lights came on the meters and lights shot up quick and. Then the car shut down I was so freaked out my husband took it to the dealer ship they stated it was. A tire valve sensor they claimed to have checked all the fluids which i no was not the oil was burnt when i got out and checked old oil they want me to pay before they can repair but tire valve is not the #1 because i had another shop change. Out the stem these random occurrences happen today and warning lights still on. I read these sensor àre covered upto 100,000 miles.

MOST DAYS OF THE WEEK, UPON START UP, I GET 3 LIGHTS THAT COME ON AND MOST OF THE TIME DO NOT GO OFF, THE 3 LIGHTS ARE: BRAKE LIGHT, ABS LIGHT, AND TRACTION CONTROL. WHEN THEN CAR IS IN MOTION, THE SPEEDOMETER DOESN'T MOVE AND MY GAS GAUGE WILL CHANGE NUMBERS WHILE IN MOTION. IN MOTION, I FEEL LIKE THE BRAKES ARE TOUCHY BUT I DON'T FEEL THE BRAKES GRIPPING LIKE THE LIGHTS SHOWN AND DON'T FEEL ANY DIFFERENCE IN SPEED OR GEAR SWITCHING.

I'VE BEEN TO 2 HYUNDAI DEALERSHIPS,...THEY BOTH TOLD ME THEY CAN FIND ANYTHING THEY CANT DUPLICATE THE PROBLEM. IT MAKES ME MAD BECAUSE I TAKE OFF WORK TO GO GET MY CAR TAKEN CARE OF, BUT TO THEM NOTHING IS WRONG. MY CAR LAGS AT TIMES. WHEN I STOP AT A LIGHT OR STOP SIGN, ITS HARD TO GO,..IT STALLS I HAVE TO FLOOR IT AT TIMES TO EVEN GET IT TO 25 0R 30. I KNOW MY CAR DOESN'T HAVE MUCH HORSEPOWER BUT SHOULDN'T HAVE TO FLOOR IT TO EVEN GET IT TO 25. THIS IS A ACCIDENT WAITING TO HAPPEN. ITS LIKE HYUNDAI WANTS YOU ON THE SIDE OF THE ROAD OR AN ACCIDENT BEFORE THEY BELIEVE YOU. I'VE SEE OTHER COMPLAINTS ABOUT THE SAME THING ON CAR COMPLIANT. I GUESS ME AND THOSE OTHER PEOPLE ARE CRAZY. I'M THINKING ABOUT GETTING A LAWYER IF THIS ISN'T TAKEN CARE IF SOON.

I'VE HAD MY 2016 HYUNDAI ACCENT 5-DOOR SINCE FEBRUARY 2016. ON SEVERAL OCCASIONS, I HAVE NOTICED TWO ISSUES. THE FIRST IS THAT COMING TO A COMPLETE STOP, WHEN PRESSING ON THE BRAKE PEDAL IT FEELS LIKE SOMETHING IS HITTING THE GROUND BENEATH MY FOOT ON THE UNDERSIDE. DEALERSHIP FOUND NOTHING BECAUSE THEY COULDN'T DUPLICATE IT. THE SECOND IS WHEN AT A STOP SIGN, ETC., AND YOU START TRYING TO INCREASE THE SPEED, THE ENGINE HAS A HARD TIME GAINING SPEED AS QUICKLY AS IT SHOULD. I HAVE TO PRESS THE ACELERATOR TO THE FLOOR BOARD TO GET MOVING. I KNOW THAT MY VEHICLE ISN'T ONE WITH A HUGE ENGINE BUT STILL IT SHOULDN'T STRUGGLE TO GAIN SPEED EVERY SINGLE TIME! I'M NOT VERY HAPPY ABOUT THIS AND WILL BE TAKING IT BACK TO CHECK BOTH THE BRAKES AND ENGINE.
