Mitsubishi Diamante — Years to Avoid
Reliability breakdown of every Mitsubishi Diamante model year. Based on NHTSA owner complaints, federal recalls, and safety investigations.
How we calculate this
Each year receives a composite risk score based on NHTSA owner complaints, federal recalls, safety investigations, and technical service bulletins. Years scoring more than 2x the model's average are flagged as “years to avoid.” Years in the lowest risk bracket are marked as “best years.” All data is sourced from the National Highway Traffic Safety Administration (NHTSA).
