Complaints for each year on the road
Each model year's NHTSA complaints divided by the calendar years it has been on sale, counting this one (a 2018 model has had 9). Older cars have had longer to collect complaints, so raw totals flatter the new ones. Blue bars are the years to avoid. Too new to judge: 2025.
Within one model, sales change less from year to year than they do between models, so a jump here is mostly a jump in problems. The call: the years to avoid are the (up to three) highest at 1.5 times the model's median rate or more, and the best are the (up to three) lowest at two thirds of it or less, from 2016 on.
