2016 Hyundai Accent Electrical System

The instrumental panel suddenly malfunctioned the abs, airbag, and check engine lights illuminated, and the speedometer dropped to zero. The instrumental panel returned to normal, but the mileage range reset to 0. This was while I was traveling on a highway going 70mph. While it did not cause an accident this time, it was very upsetting. Further it is concerning that there was a recall on the 2014 Hyundai Accent for wiring issues that could cause a fire in the engine also referred to as an intermittent. We had the car inspected and nothing was found to be wrong with the battery/alternator or starter and nothing we could do in regular maintenance to ensure the safety of this vehicle. Note the mileage of this vehicle is 108k which is interesting considering the powertrain warranty was for 100k miles.

During hot/warm weather, typically 65 degrees or hotter, as soon as I turn on my car, the traction control light, the ABS light, and emergency brake light comes on. When this happens, the speedometer does not work. The gas level on the screen will also fluctuate, as well as the odometer stops counting miles. The car will still drive normal with all these specific lights, but is obviously extremely dangerous as the speedometer does not work. Sometimes when this issue is happening, if I drive around for 10 minutes, the speedometer will start working again and all the lights go out besides the traction control light. If I then find a spot to turn off my car and on again, it goes back to normal with no lights illuminated on the dashboard, the speedometer works, and the gas gauge goes back to what it is supposed to be at. However, at the same time, the issue might seemed to have fixed itself, but then will start happening again when I’m in the middle of driving. I tried taking it to Hyundai, as at the time this first began happening my car was under warranty still, and they told me my ABS connection was corroded, so they put in a new one. This did not fix the issue at all and the issue started back up again not even 30 minutes after leaving Hyundai. I had to leave town and couldn’t get the issue checked out again right after. This all started happening when my car was around 57,000 miles. I now have almost 75,000 miles and the problem still occurs. I have noticed that this only occurs when it is hot/warm outside and the car sits for a little, as stated above. I live in NY, so during the colder winter months, this issue never happens. This all is very worrisome when your speedometer stops working out of no where, or having the thought that it’ll get worse somehow when I’m driving at higher speeds, then all of this will put myself and others in danger on the road.

The horn just stopped working out of nowhere, but it’s not the fuses, it’s the actual horn

RANDOMLY THE INSTRUMENT PANEL WILL MALFUNCTION. THE ABS, AIRBAG, AND CHECK ENGINE LIGHTS ILLUMINATE, THE SPEEDOMETER WITH DROP TO ZERO, AND THE FUEL GAUGE INDICATOR FLUCTUATES WILDLY. THIS CAN OCCUR WHILE PARKED OR WHILE DRIVING. IT HAS BEEN HAPPENING RANDOMLY FOR OVER A YEAR. DUE TO THE UNPREDICTABILITY IT HAS BEEN DIFFICULT IN HAVING THIS OCCUR IN THE PRESENCE OF A MECHANIC. I HAVE FOUND MANY POSTS ONLINE OF OTHER PEOPLE HAVING THE SAME ISSUE OVER THE PAST FEW YEARS YET A RECALL HAS NEVER BEEN ISSUED. A MALFUNCTIONING INSTRUMENT PANEL SEEMS LIKE A PRETTY SIGNIFICANT SAFETY RISK. I SUBMITTED A COMPLAINT A YEAR AGO BUT NOTHING EVER CAME OF IT.

WHILE DRIVING ON A HIGHWAY, THE ICONS ON THE INSTRUMENT PANEL FLASH, THE SPEEDOMETER DROP TO ZERO AND THEN REBOUNDS AND THE TRIP MILEAGE COUNTER CHANGES TO ZERO MILES TRAVELED. IT'S HAPPENED TWICE IN THE LAST 12 MONTHS. *TR

MY DAUGHTER CALLED TO TELL ME THAT UPON STARTING THE CAR AND STILL IN PARK, THE BRAKE LIGHT AND ABS CONTROL LIGHTS WERE LIT UP, AS WELL AS THE SPEEDOMETER WAS NOT WORKING. THIS SHOULD BE ADDRESSED BY THE MANUFACTURER AS THIS POSES A SERIOUS PROBLEM FOR A DRIVER.

MULTIPLE TIMES NOW ON THE DASH DISPLAY THE INDICATOR LIGHTS FOR THE ABS, TRACTION CONTROL, AND BRAKES ARE ILLUMINATED. THIS OCCURS WHILE THE VEHICLE IS PARKED. ADDITIONALLY, IF YOU PUT THE CAR IN GEAR AND BEGIN DRIVING, THE SPEEDOMETER DOES NOT WORK AND REMAINS AT ZERO. MANY OTHER PEOPLE HAVE REPORTED THE SAME ISSUES ON VARIOUS WEBSITES. A SAFETY RECALL SHOULD DEFINITELY BE ISSUED BEFORE IT CAUSES SOMEONE TO WRECK.

TL* THE CONTACT OWNS A 2016 HYUNDAI ACCENT. WHILE DRIVING 55 MPH, THE SPEEDOMETER GAUGE DROPPED TO 0 MPH; HOWEVER, THE VEHICLE SPEED DID NOT CHANGE. ALSO, THE PARKING BRAKE, BRAKE, ABS, AND ELECTRONIC STABILITY CONTROL WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS NOT TAKEN TO A DEALER TO BE DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED AND ADVISED THE CONTACT TO TAKE THE VEHICLE TO A DEALER. THE FAILURE MILEAGE WAS APPROXIMATELY 50,000.

WHILE DRIVING THE VEHICLE DOWN THE HIGHWAY, ALL THE DASH LIGHTS STARTED LIGHTING UP AND THE GAUGES APPEARED TO STALL IN A RANDOM PLACE, THEN RESET. I WASN'T SURE IF THE CAR WAS STALLING OR IF IT WAS JUST AN ELECTRICAL GLITCH. THIS WAS A DISTRACTION AND TOOK MY ATTENTION OFF THE ROAD AS THE CHECK ENGINE/TIRE PRESSURE/LOW FUEL/ETC LIGHTS ALL LIT UP AT THE SAME TIME AND THE GAUGES APPEARED TO BE MALFUNCTIONING MOMENTARILY. WITHIN 15 SECONDS, EVERYTHING APPEARED TO BE OPERATING NORMALLY AGAIN. THE CAR NEVER STALLED OR LOST POWER, THE GAUGES JUST MADE IT APPEAR AS IF IT DID. I SCANNED THE CODES WITH THE CAR STILL RUNNING AFTER THIS INCIDENT AND THERE WERE NO CODES (PREVIOUS, CURRENT, PROCESSING). I CALLED THE DEALER AND THEY SAID IF IT KEEPS DOING IT TO BRING IT BY BUT IF IT'S NOT ACTIVELY HAVING AN ISSUE THAT THEY CAN'T DO ANYTHING FOR IT JUST YET (REQUESTED VIA PHONE TO INSPECT FOR LOOSE CONNECTIONS/GROUNDS AT THE LEAST).
