Owner-reported complaints naming the fuel system system, filed with NHTSA

Data refreshed

Fuel system reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

I've been bringing my car to a repair shop over and over for the past month. Myself and the repair shop had to put a quart of oil once a week in the vehicle. I have spent on numerous things to get down to the problem. The engine is leaking oil. I downloadwd proof leading to the problem I need to get fixed. The problem is still there

The contact owns a 2015 Hyundai Genesis. The contact stated that the driver's side mirror failed to adjust properly to view the surroundings on the driver's side of the vehicle. The failure was causing issues and a need for chiropractic care due to the contact needing to manually turn and adjust to safely view oncoming traffic, which aggravated previous neck and back injuries. The vehicle was taken to the dealer, who diagnosed that the mirror had failed and needed to be replaced. The vehicle was not repaired. When having the oil changed, the dealer informed the contact of 2 recalls; NHTSA Campaign Number: 21V160000 (Service Brakes, Hydraulics) and NHTSA Campaign Number unknown (manufacturer number 252) and Service Campaign Manufacturer Number 965 (NHTSA ID Number unknown). The fuel module, fuse assembly, and relay were replaced or repaired. The vehicle was kept for the remedies to be completed; however, approximately 2-3 weeks after the remedies were completed, the vehicle would hesitate when driving at various speeds, the engine would stall without warning, and the vehicle would fail to start on initial start-up, intermittently. The contact used engine cleaner, seafoam, and Lucas cleaner for the engine; however, the engine failure persisted. The vehicle was towed to the dealer, who was not able to provide a diagnosis or make contact for any updates since the vehicle's been returned. The vehicle was not repaired. The manufacturer was informed of the failure and had 2 cases of the vehicle. The failure mileage was approximately 96,000.

The oil low-pressure warning light is frequently on while the engine is operating from idle to approximately 2,000 rpm. Engine operation is normal, including high performance. Complaints of this condition abound on Genesis Forums. Beside the lack of a true low oil pressure warning that may result in severe engine damage, a safety issue is present if that damage occurs on roadways with no way to escape traffic flow.

The fuel door will not open, even with the emergency latch located within the trunk. A cursory search of reddit and other forums has revealed the problem to be widespread among other Hyundai owners, with no solutions offered by Hyundai or Genesis. The safety issue is obvious in that drivers will be stranded in unexpected places.
