Genesis G80 Common Problems

ELECTRICAL SYSTEM

Owners of the 2018 Genesis G80 frequently report issues with the electrical system, particularly involving the oil pressure sensor, air conditioning, and recall-related concerns. Complaints often describe the oil pressure sensor malfunctioning at idle, causing the oil light to illuminate intermittently, which has led to at least one reported crash. Multiple owners also mention the air conditioning failing to cool effectively during extended use, especially in hot climates. Additionally, numerous reports highlight delays in addressing recall repairs due to unavailable parts, with some owners expressing concerns about potential fire risks. These issues typically arise in vehicles several years old, often beyond the manufacturer warranty period, and can pose safety risks such as impaired visibility, overheating, and uncertain oil pressure status.

Severity signals: 1 crash, 0 fire, 0 injury reports

STEERING

Owners of the 2018 Genesis G80 frequently report issues with the steering system, particularly a sticking or binding steering wheel that does not return to center without manual effort. Typical symptoms include the steering wheel remaining in the turned position during curves and requiring significant driver input to straighten, with some noting this occurs both at high and low speeds. Complaints often mention these issues arising at mileage ranges from around 27,300 to 47,500 miles. Two crash incidents are associated with steering wheel airbag non-deployment, raising safety concerns. Buyers should be aware of potential steering control issues and review the availability of any manufacturer service bulletins or warranty extensions.

Severity signals: 2 crash, 0 fire, 0 injury reports

UNKNOWN OR OTHER

Owners of the 2018 Genesis G80 frequently report issues with the air conditioning system, describing it as failing to cool effectively after extended driving, particularly in high-heat environments, with symptoms including warm air blowing and reduced cooling capacity. Complaints often involve the system shutting off or requiring a reset after the vehicle is turned off for a period. This issue is noted at various mileage points, with some reports around 24,000 to 28,000 miles. Additionally, owners describe problems with the driver side rear door latch failing to open, posing potential safety concerns in emergencies. Tire-related issues are also mentioned, with sidewall blowouts and bubbles forming in Continental tires within the first 1,000 to 6,000 miles, raising concerns about tire reliability. These complaints highlight potential safety implications, such as heat-related discomfort and compromised exit safety, that used car buyers should consider.

ELECTRICAL SYSTEM

Owners of the 2019 Genesis G80 frequently report issues with the air conditioning system, noting that it shuts down after several hours of use and fails to cool effectively, with some vents emitting hot air. Additionally, multiple complaints highlight a recall related to the electrical system, where parts necessary for the repair are unavailable, causing delays in addressing the issue. One owner describes a parasitic electrical drain from the AGM battery, which occurs after the vehicle sits for 24 hours, with the problem recurring despite recharging. These issues are reported at mileage as low as 19,000, and while no crashes or fires are mentioned, the delay in recall repairs could pose a potential safety concern.

WHEELS

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.

ENGINE

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.

AIR BAGS

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.

Severity signals: 4 crash, 0 fire, 5 injury reports

UNKNOWN OR OTHER

Owners of the 2019 Genesis G80 report several issues, primarily concerning the panoramic sunroof and steering system. Complaints frequently mention noises such as crunching and grinding from the sunroof, with concerns about its structural integrity, especially during accidents. Some owners note these issues around 34,000 miles. Additionally, multiple owners describe a persistent and startling warning to keep hands on the steering wheel, even when hands are firmly placed, particularly at highway speeds. This steering issue is reported to occur randomly and repeatedly. Another reported problem involves the power trunk latch failing, which could pose a safety risk if someone were trapped inside. These issues may be important considerations for potential buyers evaluating the vehicle's reliability and safety features.
