Overview

2015 Infiniti Q50

The 2015 Infiniti Q50 aims for a blend of luxury and sport sedan appeal. Under the hood, a potent 3.7-liter V6 engine paired with a 7-speed automatic transmission provides capable acceleration, while its rear-wheel-drive platform offers engaging dynamics. However, potential buyers should be aware of a significant number of recalls and a very high TSB count, indicating a complex service history. The driveshaft fatigue issue, in particular, requires thorough pre-purchase scrutiny.

Critical Failure Risk

A significant recall addresses driveshaft fatigue and potential breakage. This is a critical component that can lead to loss of propulsion or control if it fails.

Early detection can help you avoid a $1,500-$3,000 repair.
