Hyundai Elantra slipping problems

Filed Oct 10, 2026 · Electrical, Engine · NJ

Vehicle is still in my possession and available for inspection upon request. My safety and the safety of others was put at risk due to vibration when braking caused by warped rotors, a vehicle that pulls to one side with an off-center steering wheel, abnormal tire wear including a bald tire with a sidewall bubble, and a transmission that has twice failed and recently felt like it was going to stall while accelerating. The wheel bearing/suspension noise was confirmed by an independent repair shop (Firestone) using a listening device at highway speed; however, the dealership's own inspection gave a conflicting finding of no issue. The transmission issues have been reproduced by the dealership in the sense that two replacements were performed; however, the most recent stalling sensation has not yet been independently confirmed. The vehicle has not been inspected by police or insurance. Warning lamps/symptoms included a horn malfunction (tied to Hyundai TSB 25-BE-005H-2) and headlight issues that coincided with transmission slipping on more than one occasion. These symptoms first appeared at approximately 10,000 miles with a wheel alignment flag, and have recurred and worsened over time, including three wheel alignments, two sets of front tires, and two rotor replacements.

Transmission slippage, near failure, unable to accelerate safely past 20mph. Need to floor the gas peddle which causes me to go over the desired speed.

2016 Hyundai Elantra (75k miles) experiences severe, un-commanded Loss of Propulsive Power and a Severe Drivetrain Instability Hazard. At steady highway speeds, the automatic transmission completely loses hydraulic pressure, slips out of gear, and unexpectedly drops into a temporary "neutral." The engine suddenly revs up to high RPM on its own while losing all forward acceleration. After coasting helplessly, it violently slams back into gear, causing the vehicle to lurch forward. This also happens from a complete stop.The vehicle's OBD-II system fails to illuminate the Check Engine Light or store fault codes during these flares, providing zero warning before a loss of propulsion.This dangerous transmission slipping has occurred intermittently for several years. I repeatedly took it to an authorized Hyundai dealership to address this crash hazard. Because there was no active Check Engine Light, the dealership dismissed my concerns, refused to document it, and sent me away without a diagnosis. Recently, the service department acted in bad faith by misrepresenting my warranty terms (falsely claiming it was only 7 years) and refusing a live-data diagnostic scan. The bad faith dealership was Murdock Hyundai of Murray in [XXX], specifically the service manager Tyler as well as Krateton. The car is a verified vehicle under the Hyundai Nu 1.8L Piston Slap Class Action Settlement (TXXK Campaign). An official safety escalation case is open with Hyundai Motor America under my corporate case number XXX. I request a federal safety investigation into premature transmission pressure failure in 2016 Elantras, as this vehicle is entirely unsafe to operate.

I owned a 2021 Hyundai Elantra N Line that experienced a recurring transmission issue. In warm weather conditions the transmission would intermittently slip and stutter, causing a jerky engagement when attempting to accelerate. In cold weather the vehicle operated normally without these symptoms. When the issue occurred, the vehicle would sometimes hesitate or fail to move forward smoothly when pressing the accelerator. This created unsafe driving situations, particularly when pulling into traffic or accelerating from a stop. On multiple occasions this behavior nearly resulted in rear-end collisions because the vehicle did not respond reliably to throttle input. The issue appeared to be temperature related, as the problem consistently occurred during warmer weather while the vehicle operated normally in colder conditions. Because the vehicle could fail to accelerate predictably, this created a safety hazard for myself and other drivers. I believe this may indicate a potential defect in the transmission system.

The contact stated that while attempting to accelerate from a stop, the transmission was slipping, with the check engine warning light illuminated. The vehicle was towed to a local dealer, where it was diagnosed, and the contact was informed that the failure could not be duplicated and that no fault was found with the vehicle; however, metal shavings were found in the transmission fluid. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 100,781.

My 2015 Hyundai Elantra fits the 'window' of Elantras where the engine transmission slips gears without notice. Hyundai dealers have been replacing transmissions at no cost, if the car is still under 100,000 miles, as part of a class action settlement. As the second owner, I have no warranty rights to get Hyundai to fix my car at no cost. This is despite the Hyundai dealer just today (Aug 20, 2025) here in Las Vegas was ready to replace my transmission at no cost until they found out I am the second owner. The car is still unsafe. The need is still relevant. The dealer was willing at first. Now I am faced with an unsafe vehicle forced to possibly pass in excess of $4,000 to fix an issue that has been know and litigated.

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.

At first the car was fine when I bought if off some random guy and it drove a little rough but was good for the mean time. A month into driving the car I come to realize that the timing change needed to be replaced since it would keep turning off on its own in idle. As I was changing gears on the car after the a month of the repair from drive to reverse I realized the car’s gears were slipping and coming to find out we need a transmission change on the car. While looking into this cars reports using the vin number since I found it a little off putting that the transmission and timing chain is already giving out at 188,000 miles I come to find out the car may have a odometer rollback since it was last reported to have 256,500 miles and it that it was possibly altered. So the Timing chain and the transmission were the components that needed change. My safety was put as risk when the gear would not change redlining the car when driving in public roads cause me to limit my speed to be under the speed limit when realization of the issue set it of the car. The issue has not been confirmed only the time change since it was fixed at a service center. It has also not been inspected by manufacturer, police, or insurance since I’m not sure how to report Odometer rollback fraud. There was an engine light at the time of purchase which was the timing chain and a tire pressure light.
