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.

The contact owns a 2023 Hyundai Elantra. The contact stated that while driving 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.

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.

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. 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.

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.
