2023 HYUNDAI ELANTRA Electrical System Problems

Horn is inoperable due to internal fault. Horn receives power when button is depressed, relay actuates, but horn does not sound. There is no warning system in place for this fault.

This is the 7th time my vehicle has been parked and over night killed a battery. It’s been replaced 3 times and this battery lasted 8 months and now my vehicle is dead again. Also you can’t lock your vehicle if the battery is completely dead.

Low pressure oil light did not come on until the oil drain plug had completely fallen out. Once the light came on, the vehicle was slowed and came to a stop on the side of the highway within 2 minutes. The car completely shut off as if the battery were dead. It had to be jumped in order to put the car into neutral for the tow truck. The safety issue is that the hwy we were traveling on is 70mph. At no time, did we receive a warning until it was almost too late. The car is currently at an auto repair shop as the engine is most likely catastrophic and due to the car having no power, they want to replace not only the engine but also the 12 volt battery and it's module. The low pressure oil warning should have come on way before the plug completely fell out and the battery should not be dead. The mechanics can't even fathom why an engine would fail quickly and drain the battery as well.

I am reporting a recurring issue with my 2023 Hyundai Elantra where the low oil pressure warning light illuminates consistently during strong acceleration. This is accompanied by a distinct smoky odor from the vehicle. Based on my research into recall 23V-859, which addresses fire risks from a faulty electronic controller for the oil pump in the Idle Stop & Go system, I believe my vehicle is experiencing a related or identical failure. The symptoms strongly suggest that the defective oil pump controller is malfunctioning under load, potentially leading to dangerous overheating and a short circuit.

On multiple accounts did I find my 2023 Hyundai Elantra SEL rear camera not working. Now it displays a green screen and I’ve tested it but with someone directly right behind me while in reverse (not moving) the sensors aren’t going off. This is a huge safety concern for a lot of people who own Elantras

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.

Hi horn and low horn stopped working after 1 1/2 years of driving and only 7000 miles. This is a safety recall because it will fail West Virginia state inspection without the horn working. Also, it puts myself at risk while driving because I can't alert oncoming traffic if they are heading towards me. This could cause an accident. Hyundai Service Center will be inspecting the issue on 05/07/24.

While driving in a straight line my brakes and brake pedal were activated without any pressure being applied and maintaining about 45 mph. I pulled over to check the car and see if there was anything stuck in the wheel well and saw nothing. I got back in my car and proceeded to drive 2 blocks where i then went to park and upon turning left to pull into a parking spot my car immediately stopped and indicated that the emergency brake had been activated. I had not touched the brakes or the hand brake whatsoever and using the handbrake to turn on and off the emergency brake did not fix this i had to just wait until it was released. Upon researching this other drivers of the same model and year have experienced this problem in more dangerous situations on the freeways and at high speeds. I believe the problem has to do with the emergency brake being activated due to an electrical problem.

on my new car my backup camera has gone out in less than 7000 miles, and from what i have seen is a known defect that the Hyundai line of vehicles have and i want to make it more know of the defunct camera they are selling.

The vehicle's horn has completely stop working as of [XXX]. I took the vehicle to a toyota dealership because the Hyundai dealerships did not have any available appointments at the time. The Toyota dealership in Ardmore looked at the vehicle to see if there were any issues with fuses and wires. They were unable to find any issues. The dealership recommended I contact Hyundai. I then arranged for an appointment from Hyundai. Several days before the appointment, I was contacted by Conicelli Hyundai. They told me they are not taking any new bookings. I put a bad review on Conicelli's google review. I received a message from Conicelli's customer service department askimg me to call back. I called them back and was told that the service manager will call me back. The service manager called back and I explained that the horn is not working. The service manager told me that they just replaced a horn on someone elses car. He also related that the item is on back order. When I did some google searches for horn issues, I began to see that this is a national problem with their horn failures on various vehicles among different years. I have not driven the car since the horn failure. I believe the horn is on back order because Hyundai is having so many problems with their horn.

My headlights severely fog up during night driving or during rain, damp weather, or after any contact with water. This is an extremely common problem with 2021-2023 Hyundai Elantra (all trim levels) and causes extreme low visibility at night. Another issue is the horn which is also extremely common on 2021-2023 Hyundai Elantra (all trim levels) and mine has gone out completely twice and been replaced twice. My headlights have been inspected with the issue replicated and was told that it will not require any work because it’s “normal to have fog inside headlights” and no warranty work will be done to fix this safety issue

The horn constantly fails and needs to be replaced. This is not only an issue with the Elantra, as I've seen it as a common issue among a range of Hyundai vehicles. Even my local dealership has many horns on hand, as it is so common for them to be replaced, as they stated. I've gone through 2 horns in less than a year. This is complete negligence on Hyundai's part, as the horn is a critical safety feature of any highway vehicle. They replace it knowing it's going to fail, completely disregarding the safety of both the operator and nearby car and foot traffic.

Horn stopped working

I have contacted the dealer. I am almost ready to get a lawyer. This is the 4th lemon I’ve been sold. Seat belt is installed wrong. Software updates are available and screaming at me but the dealership Will not call Me back. Two days now. Hyundai finance has treated me Disrespectfully. I have error messages when I enter the car. The hood looks aftermarket and about to pop up. The NHtsa website says this car has recalls but not mine?? What ?? It smells like something is burning from the console. The brake collision is calibrated off. I would have a wreck. It’s not safe. Period.

The right back and front windows on this car does not work. There are times when all 4 windows do not work and all 4 doors will lock up and cannot be open from inside nor outside. This is a huge safety hazard. I took the car back to the dealer a total of 6 times. They worked on the car 4 of those six times trying to fix the issue which still exist. They finally told me there is nothing more they can do at this point. I said ok then, so it's clear the car is a lemon, so I would like a manufacturers buy back. They have ignored me. This has been going on since March 5th of this year. I took the car to another dealer for a second opinion and was advised the car is a lemon so I should contact corporate. I was provided the contact information for corporate and so I called and made a complaint. Corporate advised they would have reached back out on June 14th of this year, and to this day I have hear nothing back. I am extremely terrified of driving this car because, what is there is a fire or something, and I can't get out of the car? This car is a real safety issue and all I have gotten from the dealer is disrespect over and over and over. At one point I went back to them letting know again I do not want the car and u was asked by one of their sales person if this is about money. How insensitive. I am paying for a car that I can't even drive. I have parked this car since June 25th of this year and have to now be relying on uber or begging persons a ride. Most time it's very inconvenient. I have tried to speak with the dealer numerous amount of times, but to no avail. I don't know what else to do. Please advise accordingly. Anticipating your favorable response.

My 2023 Hyundai Elantra vehicle displays a low oil pressure message when accelerating. Is this related to the recent recall for the electric oil pump assembly that may overheat and increase the risk of a fire?

I purchased a car on December 24th 2022 and from the day I left off the lot there were electrical signals showing that the car was malfunctioning. I told [XXX] (the dealer) what was taking place and the dealership never called me or tried to assist with any problems. For months the signals were coming on and off and my last straw was when my windshield wipers stopped working in the middle of a rain storm after I had just made an in person complaint for the 3rd time about my electrical issues on the car while at the dealership on May 13th 2023. I had just been told there was nothing they could do and I called them upon leaving to tell them I could not see while driving because my wipers were not working. They told me to just go home. [XXX] (New car sales manager) hung up on me 5/17/2023 after telling me I am making assumptions when I was shown proof that the car had issues by the service department when they finally serviced my car about my complaints on 5/16/2023. He told me he was never made aware when I emailed the service manager all of my proof the day prior. I called 5 times before I could actually reach [XXX] who would have been [XXX] supervisor. They even hung up on me prior to speaking to him. I am completely disgusted & I do not feel safe in this car. [XXX] did not want to give me anything in writing that he was saying over the phone. He would not even send me an email. I don't feel valued I feel used. At this point I don't even know or have faith in this company. I am so hurt and as I told him if I were to die because of the issues then maybe he would have took accountability instead of blaming service or anyone else. I even contacted Hyundai corporate and they said there is nothing they can do because the dealership is a family run private Hyundai dealership. I have proof of all records and I will be attaching it. Attached shows different mileage dates, of incidents, official text and emails that were unanswered.
