2016 Hyundai Elantra problems

Filed Oct 1, 2026 · KS

I am reporting a recall remedy failure involving my 2016 Hyundai Elantra under Hyundai Recall 256 / the federal safety agency Recall 24V‑146 (trunk latch pawl defect). The McCarthy Olathe Hyundai dealership in Olathe, KS marked the recall as “completed,” but the trunk latch still does not open and the defect persists exactly as described in the recall notice. After the recall was marked complete, I returned to the dealership because the trunk still would not open. The dealership told me the issue was “trunk lid damage” from a prior accident and advised me to replace the trunk lid at my own expense. I paid for the trunk lid replacement, but the trunk still did not function. When I returned again, the dealership changed their explanation and said the problem was actually “rear frame damage,” and that they had been wrong to tell me to replace the trunk lid. Which I have audio recordings of but am unable to upload due to format restrictions. Despite these conflicting explanations, the recall defect remains unresolved, and I have been without trunk access for over a year. I contacted Hyundai Corporate (MyHyundai USA), but they responded that this was “not a part issue covered under warranty.” This appears to be a misunderstanding, because this is not a warranty claim — it is a recall remedy failure. The recall was marked complete even though the defect persists, and the dealership’s misdiagnosis led me to pay for repairs that did not address the recall defect. This situation has caused financial loss, safety concerns, and prolonged inability to access the trunk, spare tire, emergency equipment, and cargo space. I am requesting the federal safety agency to document this recall remedy failure and dealership misdiagnosis.

Vehicle stalls while driving which is very dangerous. All dashboard lights go on prior to stalling. No engine light is on. Knocking sound coming from engine. Dealer states engine needs to be replaced. Car has been serviced regularly despite that Hyundai denies engine replacement. The knocking sound that engine does is common between this model and year but mysteriously there has not been engine recalls.

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.

My driver side window has not been working for almost 3 years now. I have taken it to 4 mechanics and they fix it but only last a couple days. They have all say they can’t really do anything about it since they need an original piece. My AC is another issue I have that I have tried fixing 3 times now. The same issue happens they fix it and it last about a week or so. The longest it has lasted was 2 weeks. The mechanics each say it needs a new compressor and I’ve bought 3 new compressor already. I’m not sure what to do anymore.
