Summary

The 2020 INFINITI Q50 has several common issues. The most concerning issues are related to the engine (turbocharger failure) and transmission (rough shifting/slipping), which can be costly to repair. Electrical issues, such as infotainment system malfunctions and sensor failures, are also prevalent and can be disruptive. Suspension bushing wear is another common issue, leading to unwanted noises. While some issues can be resolved with software updates or relatively inexpensive repairs, others may require more significant and costly replacements or repairs, such as turbochargers, transmissions, or infotainment units.
