AIR BAGS:FRONTAL
Hyundai Motor America (Hyundai) is recalling certain 2016 Genesis Coupe vehicles. The mounting bolts securing the driver-side frontal air bag may have been insufficiently tightened, potentially causing the air bag to detach from the steering wheel.
AIR BAGS:SENSOR:OCCUPANT CLASSIFICATION
Hyundai Motor America (Hyundai) is recalling certain model year 2010-2016 Genesis Coupe vehicles manufactured December 12, 2008, to June 11, 2016. The electrical harness connector for the front passenger seat Occupant Classification System (OCS) may dislodge when the seat is moved.
SUSPENSION:REAR
Hyundai Motor America (Hyundai) is recalling certain model year 2013-2015 Genesis Coupe vehicles manufactured December 28, 2011, to April 6, 2015, equipped with manual transmissions. In the affected vehicles, if the differential and the suspension rear crossmember were not properly aligned during vehicle assembly, the bolts that secure the differential may loosen.

The concentric slave cylinder (CSC) in manual-transmission Genesis Coupes fails prematurely, causing soft or spongy clutch pedal feel and eventually inability to disengage the clutch. The internal seal leaks, allowing fluid to contaminate the clutch disc. Replacement requires tra… Repairs typically run $500-$2,000. Severity: high.
The 2.0T Theta II turbo in the Genesis Coupe suffers the same connecting-rod bearing wear mechanism that drove Hyundai's wider Theta II engine campaigns: machining debris left in the crankcase and oil journals restricts oil flow to the rod bearings, the bearings wear, and the eng… Repairs typically run $3,500-$8,000. Severity: high.
The ABS hydraulic module on 2011-2015 Genesis Coupes can leak brake fluid internally past a degraded motor-shaft O-ring, shorting the module electrically and igniting an engine compartment fire. Hyundai's Part 573 report describes certain ABS motor shaft O-ring material formulati… Repairs typically run $0-$0. Severity: high.
On manual-transmission Genesis Coupes built December 28, 2011 through April 6, 2015, improper alignment of the differential to the rear crossmember at assembly meant one or more of the three differential mounting bolts was not properly fastened. Launch torque then walks the bolts… Repairs typically run $0-$1,500. Severity: high.
The stock dual-mass flywheel on the manual-transmission Genesis Coupe is a well-documented wear item that fails well short of the clutch disc on many cars. Owners on gencoupe.com report broken internal springs, stretched or sheared rivets, and excessive rotational play, producing… Repairs typically run $1,200-$3,300. Severity: high.
The most consistently reported mechanical failure on the 3.8 Lambda V6 is a rattle on cold start from the timing chain system. Forum diagnosis converges on two causes: timing chain tensioners that bleed down oil pressure after the car sits, letting the chains slap until pressure… Repairs typically run $1,500-$3,600. Severity: high.
The electrical harness connector for the front passenger seat Occupant Classification System can dislodge when the seat is moved fore and aft, or when objects and debris under the seat contact it. With the OCS disconnected, the airbag control unit defaults to deploying only the f… Repairs typically run $0-$0. Severity: high.
The banjo-fitted oil feed line that supplies the turbocharger on the 2.0T Theta II engine is a very common leak point on the BK Genesis Coupe. Owners on gencoupe.com describe oil weeping or pouring from the feed line where it meets the turbo, in some cases losing a liter in rough… Repairs typically run $200-$700. Severity: high.
The 3.8L Lambda V6 in the BK2 Genesis Coupe consumes oil at an excessive rate, often 1 quart every 1,500-2,500 miles. The issue is related to piston ring design and valve stem seal degradation. Some engines require a quart of oil every 1,000 miles. Hyundai acknowledged the issue… Repairs typically run $50-$4,000. Severity: medium.
The rear differential on the Genesis Coupe develops a whining noise, particularly under load or deceleration. The pinion bearing and ring gear wear prematurely, especially on vehicles that have been driven aggressively or used for drifting.

Typical complaints are the transmission grabbing third early while revs… Repairs typically run $0-$2,500. Severity: medium.
Water in the trunk is close to universal on the BK Genesis Coupe. The body channels rainwater around the trunk opening and down the sides so it runs directly over the taillight housings, and the OEM foam taillight gaskets are not up to the job - forum consensus on gencoupe.com is… Repairs typically run $20-$400. Severity: medium.
The 2013 facelift switched the 3.8 Lambda V6 from port injection to gasoline direct injection. Because GDI sprays fuel straight into the cylinder, no fuel washes the back of the intake valves, and crankcase vapor routed through the PCV system bakes onto them. Owners report rough… Repairs typically run $300-$1,200. Severity: medium.
The Genesis Coupe develops a clunking noise from the steering system, traced to either the steering rack mounting bushings wearing or the intermediate steering shaft U-joint drying out. The noise is most noticeable at low speeds or when turning from lock to lock. Some owners also… Repairs typically run $5-$1,400. Severity: low.
