2021 Genesis G70 Common Problems by Component
4 owner complaints grouped by vehicle system.
UNKNOWN OR OTHER
2 complaintsSafety-relatedOwners of the 2021 Genesis G70 report issues with the engine shutting off unexpectedly, particularly at stops, often linked to the Idle Stop and Go (ISG) system. Some describe the need to restart the car if the ISG fails to engage properly, with one instance occurring at a busy intersection. Another complaint involves the car lurching forward aggressively when put into drive, followed by brake pulsation and failure to stop, leading to a crash over a railroad tie. Both complaints highlight significant safety concerns, with one owner expressing fear of driving the vehicle after these incidents. These issues appear to occur relatively early in the vehicle's lifespan, as one owner mentions the car is only five years old.
ENGINE
1 complaintThe problem occurred while the engine was on, but I was idle in the drive thru of a local pharmacy. The car had been placed in park, but engine still running while waiting at the window. Suddenly, the car began to shake and multiple indicator lights illuminated then the car completely died. No indicator light was illuminated before this issue. I had driven the car on the interstate to and from a doctor’s appointment in a different part of town that morning with no discernible issues. The car smelled strongly of gas. I was able to restart the car to move it to a safe location for towing, but the engine struggled to start and the car continued to shake violently and more gas smell came from the car. It was turned off as soon as possible and it is now at the dealership for diagnostics and repair. There was a recent recall on my vehicle for a faulty high-pressure fuel pump. My car did not have a check engine light on and did not display the appropriate code to have the fuel pump replaced, so I only received a software update. Because the issue with the recent recall was sudden loss of power that could potentially cause a wreck, I feel that this issue is likely related to the same fuel pump problem but was missed under the previous guidance for repair. In this case, I was lucky it happened while sitting still instead of while I was on a major interstate, or I could have been seriously injured.
FUEL SYSTEM
1 complaintThe contact owns a 2021 Genesis G70. The contact stated that while driving at an undisclosed speed or while the vehicle was parked, the contact became aware of gasoline fumes inside the cabin. The vehicle was taken to a local dealer on several occasions; however, no failure was found. The local dealer also performed a pressure check on the EVAP system and no failure was found. The contact started to feel nauseated with strong headaches due to the gasoline fumes. The vehicle was not repaired. The manufacturer was made aware of the failure; however, no assistance was provided. The failure mileage was approximately 72,000.

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.
