2016 Hyundai Elantra: transmission slipping

Filed Jul 8, 2026 · Transmission · UT

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.

Bought the car a yr ago and transmission started slipping and stalling sometimes even engine shutting off while driving at higher speeds unable to steer and when pulling into traffic is on interstate almost got hit because I could not speed up it's also using double the fuel while driving longer distances I tried to use my warranty 2x before my warranty was up but both neither time did Hyundai in Owensboro check what I booked the appt for. First one was booked to check transmission and power issue then called the day before and added oil change. When I arrived the tech retyped my order and changed the oil. Brought my keys I asked about the power/transmission issues and was told they didn't know to check that but at that point there was no time and had to reschedule... So I did. Waited almost 2 months booked appt for transmission / power issue and also check the fuel usage. Finish the service call quoting me over $1300 to fix the fuel issue because no one could find my warranty eventhough I had my original paperwork showing who warranty was with and also the acct number for the warranty. When I asked about transmission or power issue I was told there was no one to check that and I had to rebook but this time it was going to be 8 weeks and by then my warranty had expired. I feel like Hyundai did this on purpose because they are in cahoots with the lot I bought the car from. Now my car is getting worse and worse and scared to even drive the car im overpaying for. This was my first Hyundai and more than likely will forever be my last because the car I got was a lemon it seems, the customer service was worthless and the service even worse. I'm reporting to BBB and everywhere I can.

My vehicle started to have a slight delay when shifted from park to drive. Within a week's time the delay turned to a very hard shift which made car jump fast and hard making tires screech yet there was no check engine light. Then it started slipping out of gear on highway then it wouldn't go into the last gear and when in stop and go traffic fall out of gear when stopped then thrust really hard burning rubber when accelerating so had to distance myself far behind other cars so I wouldn't crash into them trying to accelerate after a stop. I get home safely let my vehicle rest a few hours before attempting to take car to be inspected. So I back out of drive way and my car doesn't go into drive at all and then the check engine light comes on. Now I have a friend bring scanner and the code P0722 comes up. I am disabled and on a fixed income still paying on the car. Luckily I broke down in front of my house.
