Problems owners report
Owners have filed 11 complaints with NHTSA about the 2021 ILX. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
