About the 2018 Infiniti QX50
The 2018 Infiniti QX50 is a suv that earns a Carivo score of 6.9/10 — rated Good. Its strongest dimension is Safety at 7.9/10, while Performance at 6.1/10 is where it trails the competition most noticeably. It's a capable but unexceptional suv — stronger alternatives exist if you're willing to shop the segment carefully.
Reliability and safety are the two dimensions that matter most for long-term ownership costs. At 6.9/10 for reliability, this suv trails its segment. That doesn't rule it out, but go in with eyes open on running costs. Safety lands at 7.9/10 — solid, though some rivals offer more advanced driver-assist features as standard. Confirm official results for your trim at nhtsa.gov/ratings.
Performance at 6.1/10 is a genuine liability and a score that should factor heavily into any buying decision. The powertrain and chassis dynamics trail class rivals by a meaningful margin — don't overlook it. At 7.1/10 for technology, the infotainment and driver-assist package does its job without setting benchmarks — check which features cost extra on lower trims.
Priced from $33,415–$40,361, 20 MPG, seating 5, the Infiniti QX50 sits in the mid-market bracket of the suv segment. The value score of 6.6/10 is a red flag — comparable alternatives offer meaningfully more for the same outlay. Shop the segment before deciding. At 8 years old, resale value, parts availability, and whether a successor model has improved on its weak points are all worth investigating before committing.
Verdict: The 2018 Infiniti QX50 sits in the middle of the field. Until its reliability and value and performance scores improve, stronger options exist at this price. Worth a look if it fits a specific need; otherwise use our compare tool against the segment leaders first.
