2023 Hyundai Elantra Transmission Problems

Your engine has been sputtering badly and the check engine light came on. A mechanic diagnosed oil blowing by in the engine, which is a serious internal engine problem. The dealership changed your spark plugs and cleared the code, but the sputtering continued, so your independent mechanic advised not to drive the vehicle. Hyundai is currently inspecting your car to determine if the engine needs internal repairs or replacement.

Your 2023 Elantra's low oil pressure warning light comes on during hard acceleration, and you notice a smoky smell from the engine. This matches a known issue where the oil pump controller in the Idle Stop & Go system can fail and overheat. The problem may require inspection and replacement of the oil pump controller or related electrical components.

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 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 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.

The contact owns a 2023 Hyundai Elantra. The contact received notification of NHTSA Campaign Number: 23V526000 (Power Train) however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

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?
