Hyundai Elantra electrical problems

The transmission is slipping to the point that I have almost gotten in several accidents due to impatient drives and the car not engaging in gear like it should. Vehicle also has several electrical faults reverse braking system engages at random with nothing in its way,the key not in vehicle warning will sound randomly while key is in vehicle,horn stopped working out of nowhere,while washing vehicle with keys in pocket vehicles key warning system will sound about every 30-60 seconds only when washing vehicle,random front collision warning system with nothing in front of vehicle,seat height adjustment randomly stops working but the rest of the electric seat adjustment works then seat will start working again at random. When taken to dealership for diagnoses the dealer refused to diagnose electrical issues unless I paid out of pocket even though vehicle is under full warranty and all systems listed are warrantied.

Horn stopped working! I bought the car in January of 2024 brand new off the lot in June my horn just stopped working the fuse was blown so it was replaced and within 2 months the horn went out again I contacted the dealership and horn replacement was ordered finally came in and changed out in November not sure why my horn went out but I need my horn I was almost hit 3 different times and a horn would have let the other driver know I was there so too close for my comfort!!

The HORN has been replaced on 4 separate occasions through Hyundai under warranty and it can not be fixed. This seems to be a wide spread issues involving the 2023 and 2024 Hyundai Elantra models and there are multiple TSB's at the dealerships. Hyundai has not done a recall or come up with a fix and it renders the horn useless and can cause a major safety problem or accident.

NOVEMBER 2023: PURCHASE VEHICLE. SEPTEMBER 2, 2024: DRIVING ON HIGHWAY 50-55MPH IN RIGHT LANE. NO ONE/NOTHING IN FRONT OF ME. CLEAR DAY. VEHICLE COLLISION ALERT STARTS BEEPING, VEHICLE ABRUPTLY BRAKES AND STEERS ITSELF INTO THE LEFT LANE. I FEARED FOR MY LIFE AND ALSO FOR THE PERSON WHO WAS BEHIND ME. SEPTEMBER 16-17, 2024: DROP OFF VEHICLE AT DEALERSHIP FOR OIL CHANGE. NOTFD SERVICE ADVISOR OF SEP 2 INCIDENT, REQUESTED INVESTIGATION. WAS TOLD I'D HAVE TO PAY FOR DIAGNOSTICS AND THEY WOULD LIKELY NOT FIND ANYTHING WRONG. I WAS ALSO TOLD IN SUMMARY: "NOTHING SEEMED WRONG, INCIDENT COULD HAVE BEEN A GLITCH, WE CAN TALK ABOUT TURNING OFF THE ENTIRE SAFETY FEATURE." -- I FELT COMPLETELY DISMISSED. SINCE EARLY 2024 (SHORTLY AFTER PURCHASING): • VEHICLE RANDOMLY DISABLES ALL SAFETY FEATURES WHILE I AM DRIVING. YELLOW ICONS APPEAR ON MY DASH, AND DINGING NOISES KEEP ALERTING. THIS HAPPENS ALMOST DAILY! I SHOWED PHOTOS AND VIDEOS TO A SECOND DEALERSHIP, AND SENT THEM TO HYUNDAI CORPORATE (DEC 2024). NO ONE HAS MADE ANY RESOLUTION FOR THIS. • NOTICING MOISTURE BUILD-UP IN WINDOW CREVICES. REAR WINDOWS HAVE ROLLED DOWN WHILE VEHICLE WAS PARKED OVERNIGHT ON SEVERAL OCCASIONS. NOVEMBER/DECEMBER 2024: • VEHICLE MAKING HIGH PITCH WHISTLING NOISE. PROBLEM DIAGNOSED AS CRACKED HEATER CONSOLE. SEALED/REPAIRED TWICE, IN TWO DIFFERENT SPOTS. WHY WOULDN'T THEY JUST REPLACE IT?! • HORN NOT WORKING. I WAS UNAWARE UNTIL DEALERSHIP TESTED IT. • REAR DOORS BARELY OPENING. THIS IS A SERIOUS SAFETY HAZARD. PEOPLE NEED TO BE ABLE TO GET OUT (AND IN). BROUGHT VEHICLE IN, WAS TOLD THEY "LUBED IT UP", YET THE DOORS ARE NOT OPENING FULLY AGAIN AS OF DECEMBER 2024-JANUARY 2025. DECEMBER 2024: • CONTACTED CORPORATE TO FILE COMPLAINT. SINCE I FILED IN DECEMBER 2024, WHICH IS 13 MONTHS AFTER PURCHASING VEHICLE, I WAS TOLD I DON'T QUALIFY FOR ILLINOIS LEMON LAW BUYBACK OPTION. ONE MONTH TOO LATE?! DANGEROUS AND ANNOYING PROBLEMS, AND I'M STUCK DEALING WITH THIS? MY VEHICLE IS A DEATH TRAP!

I had just drove back home from work and I was driving to pick up my child from his basketball game. I was able to pull out of my driveway and get through two stop signs before I came to a third and needed to make a left hand turn. I stopped and let the cars from the highway pass until it was my turn to go. I was proceeding through the sign and started to turn and in the middle of the turn my vehicle cuts off acceleration and stops moving in the middle of the street and turn. No lights. No warning. Just loses power. I pressed the gas and my rpm’s just reved extremely high. I couldn’t move out of the middle of the street. I pressed the gas again and the car started moving approximately 5-10 mph. Luckily the car driving by didn’t hit me as I was sitting in the middle of the road. I finally got to the side of the road and put the vehicle into park for a couple minutes and tried to take off again. I couldn’t go faster than 5mph at this time. I had to drive back home and by the time I got back I had lost reverse capabilities. Dealer said no recalls and mechanics said not much they can do because there isn’t a code or light on for them to check. I just have a new car that doesn’t drive or go into reverse. I’m going to the original dealer to see if they can help now. I believe this is possibly the transmission but I am not sure.
