Engine began sputtering really bad and the check engine light came on. I brought the vehicle to the dealership that I purchased it from and they recommended a fuel system flush and change the spark plugs. I had them change the spark plugs and the check engine was cleared but still sputtered a bit. So I brought it to my mechanic who does most of my work and his diagnosis was that oil was blowing by and to not drive it and have towed to Hyundai cause they've been seeing all kinds of engine problems on Hyundai's and that they since the warranty was 100k miles and I had just reached 104k miles that they may fix it. It is currently at Hyundai dealership being diagnosed. *I was driving on the interstate when engine began shaking in the middle of rush hour traffic making it difficult to pull over to see if I could see anything. *independent mechanic replicated and said to not drive the vehicle. *Hyundai is currently inspecting the vehicle now. *check engine light came on after the violent sputtering of the engine.
The contact owns a 2023 Hyundai Elantra. The contact stated that while the vehicle was at a full stop, the brake pedal was released, and the vehicle surged forward before the accelerator pedal was depressed. The contact stated that the failure was intermittent. There were no warning lights illuminated. The contact had taken the vehicle to a local dealer, who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 15,000.
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.
While driving in a parking lot. The car wouldn't accelerate. Kept pressing on the gas pedal but the car wouldn't move. After about 5 seconds the car shut down. I had to place the car on p then press the start button, pressed the brake pedal and then the start button again and the car turned back on.
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.
I experienced an issue where I was driving the vehicle, and then a "hybrid system fault" message appeared on the driver information display followed by the complete loss of power. This made me have to pull over to the side of the road with no ability to accelerate out of the way of traffic to come to a stop. Once I was stopped I tuned off the vehicle and tried to turn it back on, but the vehicle would not respond so I attempted pressing the 12 volt battery reset button to the left of the steering wheel to see if this would allow me to turn the vehicle on and the car came back to life with no warning lights or messages and drove normally. This happened three more times over the course of ~1. 5 hrs on my way home on the highway. I understand that things happen, I just wish there was more warning before all power was cut and the vehicle went into limp mode as this left me in a dangerous situation. The vehicle has been dropped off at the dealer and is awaiting a new hybrid battery replacement under warranty.
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 contact owns a 2023 Hyundai Elantra. The contact stated that while driving at 55 mph and above, the rpm fluctuated and the engine revved loudly. The transmission then seized in 5th gear, and the vehicle lost motive power. No warning light was illuminated. Additionally, the failure recurred while driving at 65–70 mph with the cruise control activated. The vehicle was towed to the dealer; however, the dealer was unable to duplicate the failure. The failure persisted, and the vehicle made an abnormally loud sound while the transmission was shifted into park (p). The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 20,600.
Horn has now shut off at 11k miles. Jerky shifting transmission combustion engine failed to start several occasions. Many error warnings for the lane keep assist.
Auto would not go into reverse or drive gears at startup in regular parking space. Received a bluetooth message that drive train would not function. Towed to dealership where problem confirmed. Electric engine ordered along with high voltage wires. Upon installation of these parts it was discovered that the assay harness was severely crimped during construction of vehicle at the factory and had crimped (cut) wires. Parts ordered and repaired. Hyundai refused to install new electric motor, only replaced harness and wires. Please note this appears to be a defective auto as built at the factory.

The steady-state symptom occurs less frequently but occasionally involves a momentary loss of power, almost resembling a backfire without the noise. I can only assume that this is related to brief disengagement of the clutches. I sought assistance by taking my vehicle to a local dealership who kept it for a little over a week. Unfortunately, they were unable to reproduce these issues, and no actions were taken to address my concerns. This unpredictable behavior from the vehicle often catches me and my passengers off guard and really makes it hard to trust the vehicle.
Car still jerks forward after their “repair” attempts. Car will also not accelerate on the highway and won’t go past 55 without engine codes and the car going limp.
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?.
On my way home waiting for the green light the car would not respond to the accelerator. . The engine would rev up on the tachometer but would not move. Finally the engine responded and the car took off reaching 83mph in a matter of seconds. After release of the accelerator I was able to get the car under control. At the next traffic light even with my foot on the brake the vehicle lunged forward nearly striking the car in front. I put the car in neutral and was able to use neutral and low gear to get it back home. . . The car was towed to the dealership the next morning.
