2016 HYUNDAI ELANTRA Electrical System Problems

My fuel pump comes up and my check engine light saying that it needs to be replaced when I fill up my car it automatically resets my mileage for AAA and trippy and it will tell me that I have no gas even though I just filled up or it will say I’m full when I know I’m empty so it’s not reliable. It comes and goes. And then for an electrical issue my Car will randomly stop working and then like come back up and it was underneath the positive plug. there is a clip that someone had to extend because it was too short and causing electrical surges so it’s still a problem if I go over a bump it gets loose so that clip under the positive terminal I believe is loose and makes my car shut off in the middle of driving at once and then it came right back on

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 Hyundai Elantra started completely shutting off while I was driving. This happened on multiple occasions like in slow traffic and while going high speeds on the highway. This is scary and dangerous when my toddler child is in the car. I took it to 3 different mechanics and no one can find any codes or anything wrong with it---but it continues to happen and put my life and my daughters life at risk. I have seen so many people complaining of the same thing--but nothing has happened? This last dealership has had my car for 3 weeks (and counting) but still cannot find the issue. I have about 125,000 miles on the car.

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.

Car stutters at low speed.

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.

Mileage: 70,000

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.
