2026-09-18, Fuel/Propulsion System
The vehicle was brought to an authorized Hyundai dealer to have Service Campaign TBH and 94B completed. These campaigns were explicitly designed to prevent known mechanical defects (cracked EHRS assemblies and high-voltage battery errors). The software patches failed to protect the vehicle. The physical hardware has now catastrophically failed exactly as predicted by the campaign, resulting in extreme engine overheating and a physically swollen high-voltage battery pack. Hyundai is refusing to cover the cascading physical damage caused by their own failed campaign remedy, leaving me with an active safety and fire hazard.

2026-09-18, Power Train
​My Lincoln Nautilus (~9,180 miles) logged 6 "Powertrain Malfunction / Reduced Power" alerts in the [XXX] telematics system between XXX (XXX at 7:59 PM and 8:16 PM; XXX at 1:07 PM and 1:39 PM; XXX at 11:16 PM; and XXX at 10:56 AM). Out of the 6 logged events, I experienced severe loss of motive power during two of them. On XXX, while driving 70 mph on I-95, the vehicle completely lost all propulsion. Coasting without power, I was unable to pull fully onto the shoulder, leaving the car partially stuck in active traffic and narrowly escaping a high-speed collision. Once stopped, the vehicle failed to recognize that it was in Park, causing the electronic parking brake to lock without releasin

The vehicle experiences sudden, complete electrical power loss while driving at speed on highways and city streets or on the parking. All digital displays turn off, the engine shuts down, and power-assisted steering and braking are instantly lost without prior warning, presenting an extreme collision risk. The issue first occurred in August 2025 at approximately 48,000 miles and was taken to an authorized Hyundai dealer in Michigan for warranty repair. The dealer held the vehicle for over 30 days but failed to correct the defect. The identical power failure has continued and recently escalated to daily occurrences. A second Hyundai dealer (Pacifico Hyundai, Philadelphia, PA) diagnosed an in

2026-06-22, Electrical System
I purchased this vehicle pre-owned approximately two years ago and have since developed concerns about its reliability, particularly related to the electrical and hybrid systems. In hindsight, I suspect these issues may be part of the reason the original owner traded it in to a CarMax dealer. Shortly after purchasing the vehicle, I began experiencing recurring problems with the 12V battery, including frequent instances requiring battery resets. Interestingly, these issues were significantly less frequent during colder weather. More recently, as temperatures have increased, the problem has worsened considerably. For about the past month, the vehicle loses power and dies immediately after ea

2026-05-22, Electrical System
The vehicle’s 12-volt electrical system repeatedly loses power within about 1 hour of sitting. The car becomes completely unresponsive (cannot unlock or start) and requires use of the built-in 12V battery reset button to restore power. This occurs frequently and makes the vehicle unreliable and potentially unsafe, as the car may become inoperable without warning. This appears to be an electrical system defect or parasitic power drain. The issue has been ongoing.
