NHTSA has received 26 owner complaints about the 2018 Lexus NX, or 3.0 per year on the road — far fewer complaints than typical (complaint index 0.07, where 1.00 is the average of all tracked vehicles). Among the 76 model-year 2018 vehicles we track, it ranks #4 of 76 by complaints per year (#1 = fewest). Against other Lexus models its rate is 60% lower; against other Luxury SUVs it is 79% lower.
Counts are normalized by time on the road, not by sales volume: a popular model generates more reports than a rare one, and complaints are not verified individually. How we count
Limited data: fewer than 30 complaints, so shares and indexes are unstable.
