Should You Buy the 2021 Infiniti Q50?

The 2021 Infiniti Q50 offers compelling performance and luxury aesthetics for its price, but it's a vehicle that demands attention to maintenance. While the core platform is solid, the powerful VR30DDTT twin-turbo engine carries known risks, primarily with its turbochargers and associated cooling components, which can lead to expensive repairs if neglected. This is not a 'set it and forget it' car, but a rewarding one for owners willing to be proactive.

While the 2021 Infiniti Q50 delivers an exhilarating driving experience and luxury amenities, its specific Achilles' heel in the VR30DDTT engine's turbochargers warrants careful consideration. It’s a rewarding car for those who can afford meticulous maintenance and potential high-cost repairs, but it's not the worry…
