What the Complaint Data Suggests

Editorial interpretation of NHTSA public complaint data. Source: nhtsa.gov. Complaints are owner-submitted and do not confirm a defect. Methodology

Based on 92 consumer complaints for the 2018 Genesis G80, issues appear concentrated in electrical faults, steering defects, and engine problems. There are 6 recalls and 8 crash-related complaints, but the data is limited to a single model year and low confidence.

Key Findings
  • Electrical faults account for the highest number of complaints (22).
  • Steering defects are the second most reported issue (15 complaints).
  • Engine problems are also notable with 14 complaints.
Top Concerns
  • Electrical faults, including potential wiring or component failures.
  • Steering defects, which may affect vehicle control.
  • Engine problems, which could impact reliability.
Data note: NHTSA complaints are consumer-submitted and do not confirm a manufacturing defect. The confidence level is low, meaning the data may not fully represent the vehicle's reliability. Only one model year (2018) is analyzed, limiting generalizability.
