2016 Hyundai Elantra Electrical Problems

Your brake light bulbs (left and center) keep burning out every 3 months or less, likely due to excessive electrical current reaching them. After replacing the bulbs, your battery began draining, and you discovered that removing the brake lamp fuse prevents the battery from dying—but this also triggers your ABS warning light since that system depends on the same circuit. Your dealership quoted $500 to replace the brake lamp relay and ABS components, which you declined. The underlying issue appears to be a short circuit or electrical fault in the brake light circuit that's affecting multiple Hyundai and Kia vehicles across different model years.

Your fuel pump warning light keeps coming on, and your fuel gauge is unreliable—sometimes showing empty when full or full when empty, and resetting your trip meter when you fill up. Additionally, your car randomly shuts off while driving and then restarts on its own, which appears to be caused by a loose clip under the positive battery terminal that was extended to fit properly and now comes loose over bumps, causing electrical connection issues.

Just driving down the road and the drivers side front window fell down. I tried to push the switch for to make it go lback up because it was windy and rainy. It just made the window drop down more. I was wondering if anyone else has had this complaint . It’s pulled back up and taped but it won’t go back up and tape keeps coming loose. It’s expensive to fix . I also fixed my trunk latch which was on a recall because when I called the dealer at that time there was no recall on it. I was stuck at Walmart and it wouldn’t close. The dealer wanted over 700 to fix trunk latch so I bought the part to fix it but I am checking to see if anyone else has complained on the window motor .

Clockspring Failure. 2016 hyundai elantra, 123k miles. Airbag light on, horn does not function. Likely unavailable for inspection due to being replaced soon. Inability to use horn to alert reckless drivers swerving into my lane. Airbag will not deploy if needed in an accident. The dealership seemed aware that the clocksprings go out in Hyundai's and is confident this is the issue. Warning lamp prior/at the same time as the horn stopped working.

My Elantra stalled while driving twice the other day. The first time I occurred on a Highway inter belt and the second occurred in slow moving traffic. I had the car evaluated by 2 different repair shops. Both said they could not reduplicate the problem or find any malfunctioning codes. No warning lights appeared when the car stalled. I had this happen before last fall. I had it repaired. They changed spark plugs, performed engine oil system purge, serviced fuel injector and air induction and realigned tires. Until the day before yesterday, the car performed well. In researching my car issue, I have learned that this is a top complaint of many 2016 Elantra owners.

I was driving my vehicle damages stop accelerating the check engine light battery light and all light all came on in a vehicle just came to a complete stop and did not let me restart the vehicle. This has happened to me a second time.

Engine Code: P0335 Crankshaft Position Sensor 'A' Circuit Severe Issue Consequences of Continued Driving - Rough running - possible Misfire - May not start In my case I was at work and it wouldn’t start at all. It ended up having to be towed. Had the battery tested and it was fine then I bought a “FIXD” sensor and it told me the problem

MY CAR IS A PUSH START N IT WILL NOT TURN OFF .. I OUT THE BOTTOM TO TURN IT OFF BUT THE ENGINE IS STILL CONSTANTLY RUNNING IT WON'T TURN OFF

THE CAR DOES NOT TURN OVER WHEN YOU INITIALLY START CAR YOU HAVE TO TURN THE KEY BACK AND TRY STARTING AGAIN IT HAS BEEN CONSISTENTLY DOING THIS FOR OVER A YEAR AND NO MECHANIC CAN FIGURE OUT WHAT THE PROBLEM IS. OTHER THAN THAT THERE IS NO ISSUES WITH THE DRIVING.

WHEN I ATTEMPT TO START THE CAR THE ENGINE TURNS BUT WON'T TURN OVER. THE CAR DOES THIS MORE OFTEN IN VERY COLD WEATHER. EVEN IN WARM WEATHER IT WILL START SOMETIMES AND SOMETIMES I HAVE TO TRY MULTIPLE TIMES AND SOMETIMES IT WILL NOT START AT ALL. THERE ARE NO CHECK ENGINE OR OTHER INDICATORS THAT THERE IS AN ISSUE WITH THE CAR. THE ONLY OTHER THING THAT MAY OR MAY NOT BE RELATED THAT IS DIFFERENT FROM WHAT I NORMALLY EXPECT IS THAT SOMETIMES THE WHILE DRIVING, THE CAR WILL NOT ACCELERATE IN A TIMELY MANNER. THERE IS A BIT OF A HESITATION AS IF THE FUEL OUTPUT IS NOT INCREASING. THIS HAPPENS WHILE I'M ALREADY DRIVING (FOR EXAMPLE WHEN I'M GOING FROM THE ACCESS ROAD AND ENTERING THE HIGHWAY OR WHEN THERE IS A SPEED LIMIT INCREASE OF SOME KIND). I WAS TOLD BY A MECHANIC THAT THE PART AFFECTED IS CONNECTED TO OTHER SYSTEMS IN THE CAR THAT HAVE AN ELECTRICAL COMPONENT SUCH AS THE FUEL PUMP.

HI... I OWN 11 ELANTRA'S. 4-2013, 3-2016, 2-2018, 1-2019, 1-2020. I OWN A DRIVING SCHOOL. THEY ALL HAVE A PROBLEM WITH BURNING OUT LIGHT BULBS, HEADLIGHTS ,SIDE MARKERS AND TAIL LIGHTS. I AM REPLACING BULBS 2 TO 3 TIMES A WEEK. I ALSO HAD TO REPLACE SOCKETS BECAUSE THEY MELTED. THE PLASTIC HOLDERS FOR THE HEADLIGHTS AND THE CENTER BRAKE LIGHT ALSO MELTED. I WOULD LIKE TO KNOW IF THERE IS A REMEDY FOR THIS OR ONE IN THE PROCESS. I ALSO HAVE A COMPLAINT ON WHY IT SO DIFFICULT TO REMOVE THE HEADLIGHT BULBS.

STARTED ASCENDING OVER A BRIDGE WHEN CAR STARTED TO PUTTER. THEN SMOKE CAME OUT OF THE TAILPIPE. POWER FLICKERED THEN WENT OFF. WAS ABLE TO COAST TO THE SIDE OF THE ROAD. TURNED OFF THE CAR AND IT WAS SMOKING. LOOKED UNDERNEATH THE CAR AND SAW DRIPPING FLUID THEN A SPARK. THAT IS WHEN THE CAR CAUGHT ON FIRE.

WHEN CAR IS SLOWING AT INTERSECTION, CAR WILL SHAKE VIOLENTLY AND COMPLETELY SHUT DOWN. ONCE CAR IS PUT IN PARK AND KEY IS TAKEN OUT, CAR STARTS UP IMMEDIATELY. HAS HAPPENED 5 TIMES OVER THE COURSE OF 2 WEEKS. SEEMS LIKE I HAVE TO PUT MORE PRESSURE ON GAS PEDAL TO GO EVEN SLIGHTLY FASTER.

WHILE DRIVING THE CLOCK WILL START TO FLASH THEN THE HEADLIGHTS WILL FLASH AS THE RADIO/CLOCK FLASHES. IF HEAD LIGHTS ARE OFF THE LIGHT BY GAUGES WILL START FLASHING MAKING A CLICKING NOISE, THE BATTERY LIGHT WILL SOMETIMES COME ON AND FLASH ALSO. IF I TURN THE AIR ON THE FLASHING WILL STOP. THIS HAS HAPPENED ABOUT 6 TIMES IN THE LAST TWO WEEKS. *TR
