About QX50 and QX55
The QX50 began life as the EX35 in 2007, a compact, rear-drive-based crossover related to the G35 sedan. Renamed QX50 in 2014, it was reinvented for 2019 on a front-drive platform and became the debut vehicle for one of the most ambitious engines of its era: a variable-compression turbocharged four-cylinder called VC-Turbo, which could change its compression ratio on the fly to balance power and efficiency. The QX55, introduced for 2022, was a fastback-roofed version that deliberately echoed the much-loved FX.
Both were built in Mexico, at a plant Nissan shared with Mercedes-Benz, and both were praised for their stylish cabins, comfortable rides and distinctive designs. Critics were less kind about their continuously variable transmissions, their fuel economy and the VC-Turbo's real-world benefits, which proved harder to feel than to explain. Sales never matched those of rivals like the Lexus NX and RX, BMW X3 and X4, Audi Q5 and Mercedes-Benz GLC.
Production of both has since ended, and Infiniti's newer QX65 effectively takes up the QX55's coupe-SUV mission. That makes this a page about used cars, resale and ownership: depreciation studies, recall notices, engine reliability stories and buying advice, along with the wider news about Infiniti and Nissan that shaped the pair's fate. For used buyers, a well-kept QX50 can offer a lot of luxury for the money, provided its service records and recall work are in order.
