2023 HYUNDAI ELANTRA Complaints

When driving in bad weather the car started to slide when my husband tried to turn the steering wheel and the steering wheel locked not allowing him to turn the car to avoid the curb. My husband has driven in snow for years as he was born in upstate NY and he has never had a vehicle lock when sliding.

UNKNOWN I had the lane assist feature on and was taking the second lane from right to turn off to exit when the alarm went off, the wheel turned itself and it started braking. There was nothing where it was trying to avoid and actually almost had me run into another by turning me left back onto the freeway while trying to stop. It’s never happened to me before and I take that way regularly.

The contact owns a 2023 Hyundai Elantra N. The contact stated that there was an oil leak underneath the vehicle. The vehicle was taken to the dealer a total of 4 times. The dealer completed an oil consumption test and found that the engine was consuming one quart of engine oil every 100 miles driven. The vehicle had failed the oil consumption test twice. The dealer diagnosed the vehicle and determined that the engine needed to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the failure and opened a case. The failure mileage was approximately 1,520.

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.

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.

I bought my car April 2023 brand new. I noticed today the horn was not working. I have less that 30k miles on my car. Hyundai is telling me the horn is not included in the warranty. Someone cut me off and I tried to honk my horn to tell them they were close and it didn't work.

Both high and low horns failed and the vehicle has 61,000 miles. Hyundai said this is a “known issue” to the point that they keep these parts in stock and replace them regularly. This is a safety concern, and required for safety inspection.

Code P1326 coming on after car wash. This a known issue across the cars community. Remedy needs to be taken, goes into limp mode on interstate speeds which is very dangerous.

Horn has stopped working. A driver was about to change lanes into my vehicle on the highway, and I went to honk my horn to alert them, but it would not work. It is unclear if the issue is with the sensor in the steering wheel, or with the wiring or horn itself. I have continued to test the horn over the next few days and confirmed that the issue is persistent. The lack of a horn meant I was nearly able to avoid an accident by swerving away from the other vehicle. If there had not been a gap in traffic, I wouldn't have been so lucky. The vehicle is available for inspection. I have an appointment with the dealer on Friday 1/3/25 to have this addressed, likely under warranty. No one else has inspected the vehicle at this time, and there are no warning notifications, etc.

While driving at highway speeds the vehicle will suddenly decelerate forcing vehicles behind said vehicle to make defensive maneuvers to avoid hitting our vehicle. We have taken the vehicle to the dealership twice for this condition. This time we were told it was the EGR valve, but it was on backorder. We are now forced to drive this vehicle until it is repaired.
