Forward collision avoidance, Nov 25, 2025
On 11/18/ 25 I was driving in highway traffic at 60MPH and car suddenly slowed down to 30MPH. My car would not accelerate no matter how hard I tried. With luck and prayer I moved over two lanes to shoulder...shut off the car for about 10 sec...restarted...and car ran normal again. I When deceleration occurred I saw a notice-symbol light up on the infotainment panel in a black space directly parallel to the total mileage odometer. On 11/21/25 I went to dealer, who checked car out and did not find any problem. I then went online and saw ISLA...Intelligent Speed Limit Assistance...a choice I did not have on my infotainment system. If I had it, I wanted to turn mine OFF. We're scared it could happen again.

While driving in the rain, car reported "Check Forward Safety System". Error has not gone away multiple weeks later. Hyundai dealer's first reaction was "Oh yes, this happens all the time" (!!) but then refused warranty repair because car is in other than pristine condition, despite being only two years old, still under warranty, with pristine front bumper. Without this sensor, adaptive cruise control, collision warning system, and automatic emergency braking do not work.

I was on a delivery yesterday when this first occurred. I put my car into reverse and proceded to back up when my engine cut off suddenly and a loud warning came on , on my dash by the steering wheel it said ... engine off, shift to neutral and restart. That is what I did and it restarted and I continued on with my deliveries. Then the exact same thing happened again today so I called the dealership and they said there is a recall with the isg system that could be the issue but no resolution yet so there's nothing they can do. In the meantime time I can't use my vehicle for work as im a full time food delivery driver and I have to back up into roadways multiple times a day going in and out of driveways and I can't risk my safety or other drivers safety as my car may turn off in the roadway.

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.

Engine, Sep 14, 2025
Vehicle routinely sputters and stalls at slow speeds. This happens once or twice during most times I use the car. This has happened in intersections and on highways at stop and go traffic. The car is not safe to drive. I haves brought the vehicle into the dealer at least three times for this and they have replaced a different valve (don't know what it was) on two of the occasions but the problem continues. I have an upcoming appointment with my authorized Hyundai dealer (the vehicle is still under warranty) and hope I have better luck next time. But a vehicle that stalls on every trip is not safety.

The vehicles horn does not when pressed. Multiple other users have complained of the same issue affecting their vehicle as well.

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

Horn stopped working at at around 30,000 miles. After taking it to the dealership to get fixed it stopped working at 70,000 miles again.

I was driving in completely clear weather on [XXX] . No cars were within at least 100 ft in front of my vehicle. Suddenly the emergency braking system alarm flared and the brake engaged. This could have caused someone tor rear end my car but luckily no one was behind me. The brake also fairly quickly disengaged. I took it to Pearson Hyundai where I had bought the car ([XXX]). They had the car for a couple of days and said they found nothing. They could not duplicate the incident. I would not have wanted to ever drive the car again as is, but the technician pointed out I could leave on the warning but eliminate the braking in settings. I am reporting this because if this happened with a child in the back seat on a road like the 95 it could do incredible harm INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

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.

The rear view backup camera doesn’t show. Some days it works most of the time it’s green and distorted. I know it’s common issue so it should be apart of the 21-22 Elantra recall

Horn just stopped working! Fuses are intact. I see this is a consistent complaint for this model. Cannot pass safety inspection and I’ve only had the car for a year
Power train, Service brakes, Lane departure, Oct 27, 2024, crash
I have been encountering a series of troubling and erratic issues with my vehicle. These problems occur under various driving conditions, including acceleration, steady-state driving, and braking. However, the most prevalent and problematic occurrences seem to transpire during acceleration and braking. During acceleration, I've observed inconsistent behavior. Sometimes, the car shifts smoothly, with minimal torque drop between gears. On other occasions, the vehicle accelerates initially but then abruptly loses all power between gears, resembling the sensation of someone engaging the clutch in a manual vehicle and shifting slowly. This results in a temporary power loss lasting 1-2 seconds, followed by an over-revving and clutch slip, leading to an unintended surge in acceleration. The issues I've encountered during braking typically begin with a chattering noise and vibrations that seem to be an imbalanced or shocked reciprocating mass, I can assume maybe one of the clutches/flywheel . This is often followed by decreased brake pedal linearity, requiring increased brake pedal pressure to stop. This normally results in an unintended aggressive forward jerk just before coming to a stop, akin to someone releasing a clutch on a manual transmission vehicle too quickly when downshifting while the engine speed is too low. One night I went to get diapers for my baby and it was raining and I hit the breaks and the breaks lost control and I crashed into a median wall and my car kept spinning around. Ambulance were called and I was admitted to the hospital with minor injuries.

The vehicle applies automatic emergency brakes when another vehicle passes close by from behind in an adjacent lane, when the Blind Spot Collision Avoidance Assist, feature is set to “Active Assist.” The owner’s manual states that this feature operates when the turn signal is turned on in the direction of the detected vehicle. However, my experience shows that the car applies brakes even when the turn signal is off and the vehicle is driving straight within its lane, without changing lanes. As per NHTSA description automatic breaks to be applied if the driver ignores the warning and tries to change the lane. But Hyundai design applies brakes even if car driven within lane without any warning before applying break

There was a recent over the air software update. Since the update, the speed limit shown on the dashboard, does not match the posted speed limit. This causes the cruise control to change from 70mph, to 55mph. This happened a few times, and always at the same place on the PA Turnpike. Yesterday it did it and there was a tractor trailer behind me. When my car started to decelerate, the driver of the truck laid on the horn because he had to react quickly. I am lucky that he did not hit the rear of my car. This is a safety issue! Also, why does Hyundai feel the need to control drivers speed, especially when there is no government mandate to do so.

Car was breaking hard because of Active Assist despite that no car was in front. It was breaking consistently until I finally was able to disable the Active Assist. Luckily, there was traffic and driving at less than 20mph but this also happened some time last year at the same area where there was no traffic and was going at a minimum speed of 45mph and to have the Active Assist break hard put me at great risk of getting rear ended. I have footage from the dash cam which I unfortunately cannot attach as it's more than the 10MB limit.

The contact owns a 2023 Hyundai Elantra. The contact stated while driving 70 MPH, the vehicle lost motive power and stalled. During the failure the check engine warning light illuminated. The vehicle was taken to the local dealer to be diagnosed. The contact was informed that the cause of the failure was due to faulty motor mount bushings. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 290.

On July 28th 2024, I took my new 2023 Hyundai Elantra to its first oil change at a Take 5 oil change center. They replaced the oil, filter, checked the fluid levels in my car, and topped the fluids off. That evening, I noticed there was a liquid leaking from behind the passenger side tire, and at first thought it was water from the A/C, but in the morning, I noticed a puddle of liquid was under the car. I went back to Take 5 on August 5th and informed them that I believed there was coolant leaking from the vehicle following my oil change. The worker checked and said my coolant reservoir was completely empty, and he refilled the coolant and told me to take it to be diagnosed at a full service auto center. On August 13th I noticed there was a smell of burning metal coming from the engine bay when I turned the car on and took it to a Firestone where they informed me that the radiator cap had failed and was no longer holding the pressure in the radiator, and that almost all the coolant had leaked from my car. I had the radiator cap replaced and kept the original to take to the Hyundai dealership to see if this was a manufacturers defect or the result of improper handling by the Take 5 worker.
