Complaints by area

Each bar is the share of this model year's 245 complaints that name that area. A complaint can name more than one area, so the shares add up to more than 100%.

12 smaller areas not shown (56 complaints in total).

Do not compare models by these numbers. NHTSA has no sales count for each model, so a model with more complaints may just have sold more cars. Use them to see which areas owners write about, not to rank cars.
