Infiniti QX70 reliability by year
Each year is complaints filed in that year’s first 3 years on the road, divided by however many of those years have passed. A model year younger than 3 years is too early to compare, so it is left out of the years named as having the fewest or the most complaints. Recalls are a separate count. The numbers are for the US-market Infiniti QX70. How we count.

Known issues for this generation
NHTSA owner complaints on 2014-2017 QX70 repeatedly describe brake-fluid leaks onto the ABS actuator circuit board that can melt harnesses or cause an electrical fire (for example ODI 11639483 on a 2015), plus sudden loss of braking effect and pedal fade at stops. Separate filings report transmission fail-to-shift / high-rev bangs on highway and inaccurate fuel-gauge readings that led to unexpected stalls. Confirm ABS module condition, brake hydraulics, and transmission service history on any used example; VIN-check NHTSA for open campaigns. Campaign 14V-683 appears in some QX70 API rows but its Summary names Q70/QX80, not QX70—do not treat that text as a QX70 recall.
