  • Estimated Cost to Fix: $500 - $5000+ depending on the extent of the damage.
  • Recalls: None Found

4.6L V8

• Oil Consumption
  • Description/Symptoms: Excessive oil consumption requiring frequent topping off between oil changes.
  • Solution: Check for leaks, evaluate PCV valve function, and consider compression tests to assess the condition of piston rings. Possible solutions may include replacing the PCV valve, repairing oil leaks, or an engine rebuild if piston rings are the issue.
  • Estimated Cost to Fix: $50 - $4000+ depending on the cause and severity.

Summary

The 2012 Hyundai Genesis, while a luxurious and comfortable vehicle, is not without its share of potential issues. Engine problems like knocking noises, oil consumption, and valve train noise can be costly to address. Transmission issues can also be a significant expense. Electrical gremlins, such as battery drain and infotainment problems, are also common. Air suspension failures, if equipped, can add to the maintenance costs. The severity of these issues varies, but some repairs can be quite expensive, making it important to have a pre-purchase inspection performed by a qualified mechanic.
