2020 Genesis G80 Common Problems by Component
10 owner complaints grouped by vehicle system.
UNKNOWN OR OTHER
4 complaintsOwners of the 2020 Genesis G80 frequently report issues with the air conditioning system, particularly on hot days. Complaints describe the AC working initially but then stopping, with airflow ceasing, and heat being emitted instead of cold air. This problem is noted to occur during extremely high temperatures, with some owners mentioning temperatures exceeding 110°F inside the vehicle. Multiple owners also mention difficulties in getting the issue resolved, as dealers are unable to reproduce the problem. Additionally, there is a report of a recall related to a faulty turbo oil feed pipe leading to oil leaks and potential fire risks, with subsequent complaints of coolant leaks after attempted repairs. These issues suggest potential safety concerns due to extreme cabin temperatures and the risk of fire from oil leaks, which could be important considerations for used car buyers.
SERVICE BRAKES
2 complaintsSafety-relatedOwners of the 2020 Genesis G80 report issues related to the service brakes, with one incident involving a crash when the brakes failed at low speed, causing the vehicle to collide with a steel post. Another complaint involves dissatisfaction with a recall fix, where the dealer replaced a 10 amp fuse with a 20 amp fuse in response to an ABS module defect. These reports highlight potential safety implications, including brake failure and concerns about the adequacy of recall repairs. Buyers should be aware that these issues may not be isolated and could affect vehicle safety and reliability.
ELECTRICAL SYSTEM
2 complaintsOwners of the 2020 Genesis G80 report issues related to the electrical system, with symptoms including frequent battery drainage requiring jump-starts and unusual noises when a power source is connected. Some owners mention problems with the car running hot without warning lights and connectivity issues with USB and phone connections, such as crackling sounds. Additionally, there are reports of rodent damage to soy-based wire coatings, leading to repeated repairs for chewed wiring, including the starter wiring. These issues are noted at around 12,000 miles. While no crashes or safety incidents are reported, the recurring electrical problems and rodent-related damage may concern potential buyers.
TIRES (2 complaints)
TIRES
2 complaintsOwners of the 2020 Genesis G80 report issues with Continental ProContact Rx tires, specifically sizes 275/35R19 and 245/40R19.

How We Calculate Reliability Scores
Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.
Key Ranking Factors
Complaint Severity
NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.
Repair Costs
Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.
Recall Impact
Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.
Issue Diversity
Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.
Scores are grouped into four tiers:
- 80–100: Excellent— Top-tier reliability, minimal issues
- 60–79: Good— Reliable with some minor concerns
- 40–59: Mixed— Notable issues, research before buying
- 0–39: Risky— Significant problems, proceed with caution
Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
