2018 Genesis G80 Reliability Report

Owners report frequent issues with the Continental ProContact TX tires on the 2018 Genesis G80, primarily involving sidewall failures and bubbles. Complaints frequently mention sidewall gashes, blowouts, and bubbles occurring at relatively low mileages, often under 10,000 miles, with some reports of failures as early as 6,000 miles. These tire failures are noted both while the vehicle is in motion and while parked, and some owners attribute these issues to road hazards like potholes. The recurring nature of these failures suggests potential safety implications, as several owners express concerns about driving at higher speeds due to the risk of tire blowouts. Buyers considering this vehicle may want to investigate the condition of the tires and consider potential replacement options.

Owners report several engine-related issues with the 2018 Genesis G80. A recurring problem involves engine stalling, where the vehicle shuts off unexpectedly during driving, requiring a restart. Complaints frequently mention an oil pressure sensor issue that triggers warnings, especially in cooler temperatures, potentially obscuring more serious engine problems. Multiple owners describe oil leaks related to previously addressed recalls, with some noting smoke and fire hazards. These issues often appear around 38,500 to 43,628 miles. Safety implications include potential fire risks and loss of vehicle control due to engine stalling.

Owners of the 2018 Genesis G80 report multiple issues related to airbag deployment, particularly during crash events. Complaints frequently mention that the driver's airbag does not deploy, even in severe accidents, while other airbags may deploy inconsistently or only partially. Several reports describe conflicting vehicle identification data from the Event Data Recorder and Genesis systems, which may impact safety-critical information. Typical symptoms include airbag warning lights and increased resistance codes, with some vehicles showing these issues around 126,000 to 127,000 miles. The safety implications are significant, as four complaints involve crashes, resulting in five injuries, highlighting the potential risk to occupants.

Owners of the 2018 Genesis G80 frequently report issues with the transmission unexpectedly shifting from drive to neutral, especially after reversing. This issue is often mentioned alongside symptoms such as the vehicle failing to accelerate after making a turn and requiring multiple attempts to stay in drive. Complaints also describe a concerning incident involving a crash where the brakes failed to respond, leading to unintended acceleration and loss of control. These issues are noted at various mileage ranges, with one owner specifying failures occurring around 25,000 to 31,158 miles. The reports indicate potential safety implications, including crashes and loss of vehicle control.

Owners of the 2018 Genesis G80 commonly report issues with the vehicle's sunroof glass, with multiple incidents of the glass exploding outward while driving at highway speeds. These occurrences are described as sudden, with a loud pop or explosion, and typically happen in clear weather conditions without apparent external impact. The complaints do not specify a consistent mileage range for these incidents, but they do highlight potential safety concerns, such as the risk of flying debris and glass entering the cabin. Additionally, one owner reports a rear passenger door that fails to open, posing a safety risk for passengers needing to exit the vehicle. These issues are important for potential buyers to consider, particularly regarding the structural integrity of the sunroof.

Owners of the 2018 Genesis G80 report several issues related to the engine and engine cooling system. Commonly reported symptoms include the illumination of the Check Oil and Low Oil warning lights while idling, engine overheating, and white smoke emanating from under the vehicle. These issues are often observed at mileages ranging from approximately 45,000 to 72,200 miles. Complaints also highlight problems with the turbo pipe seal failing, leading to oil dripping onto the exhaust manifold, and difficulties obtaining parts for recall-related repairs. While no crashes or fires are reported, potential buyers should be aware of these issues, particularly concerning engine overheating and oil leaks, as they may affect vehicle reliability.

Owners of the 2018 Genesis G80 frequently report issues related to a recall for the service brakes, specifically concerning the unavailability of repair parts. Complaints consistently mention that despite receiving recall notifications, parts required for the hydraulic brake repair are not available, leading to delays in completing the recall work. No actual brake failures are reported by owners, and there are no mentions of crashes, fires, or loss of control related to this issue. The recurring theme in these complaints is the extended wait time for parts, which may be a consideration for potential buyers looking for timely recall resolutions.
