Known issues on the 2023 QX80. The federal record holds 1 recall for this model year. It concerns certain 2023 QX80 vehicles equipped with 22-inch wheels, whose certification label printed the wrong gross axle weight rating; an owner trusting that figure could load the SUV beyond what it can carry and raise the risk of a crash. The fix is a corrected label. Owners have lodged 2 complaints, one on the electrical system and one on forward collision avoidance. For the suspension, the electrical system and the forward collision avoidance system these touch, the manual supplies specifications, wiring diagrams and diagnostics.
