Everything below is an owner-reported complaint submitted to NHTSA about the 2015 Hyundai Genesis Coupe, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.

Each component in detail
What the reports in each category say, in the owners' own words
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
The contact owns a 2015 Hyundai Genesis Coupe. The contact stated while driving 10–20 MPH, the vehicle went into LIMP Mode in the first twenty minutes of driving. The vehicle speed was reduced. The check engine warning light was illuminated. The vehicle was taken to the local dealer, but the dealer was unable to determine the cause of the failure. The dealer cleared the DTC codes. The vehicle was not diagnosed or repaired. While driving, the check engine light warning illuminated. The vehicle was taken to another local dealer, Happy Hyundai (9121S Cicero Ave. Oak Lawn, IL 660453), where it was diagnosed that the accelerator position sensor needed to be replaced. The throttle body needed to be cleaned and replaced. The vehicle was not repaired. The manufacturer was contacted. The approximate failure mileage was 34,000.
While driving I noticed an engine noise/rattle about 3000RPM. The engine seemed to run fine but was making this abnormal noise. At 73,083 miles I towed the car to the Hyundai dealer. They found an anomaly in cylinder #5 and recommended engine replacement but refused warranty powertrain coverage because I am not the original owner. They also refused goodwill coverage even though this is a known issue with Hyundai engines.

Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
The differential mounting bolt on the passenger side (the only one on that side) backed out and broke causing that side of the differential to smack the bottom of the car and then sag on the passenger side after letting off the throttle. Once it dropped it made the car come to a compete stop fast. Luckily there was no accident. This exact issue has already been fixed previously under recall, due to this the dealership nor manufacturer is wanting to fix it under the recall again.
