Overview

2015 Infiniti QX50

The 2015 Infiniti QX50, a compact luxury SUV, pairs a potent 3.7-liter V6 engine with rear-wheel drive for engaging performance. Its upscale interior and practical size make it a compelling used option. However, prospective buyers should be aware of its 63 Technical Service Bulletins (TSBs), which, while not safety recalls, indicate areas where the manufacturer identified potential issues. The absence of recalls and complaints is a positive sign, but the TSB volume necessitates a thorough pre-purchase inspection.

Critical Failure Risk

Leaking oil can originate from various seals and gaskets, including the valve covers or oil pan. Addressing leaks promptly prevents potential engine damage from low oil levels.

Early detection can help you avoid a $300-$800 repair.
