About this comparison
What Porsche 911 Carrera 4 Cabriolet years have the most complaints?
Adjusted for years on the road, 2022 drew at least twice the typical rate of NHTSA owner complaints among the 11 model years compared.
Is this a reliability rating?
No. These are counts of unverified owner complaints to NHTSA. They are not adjusted for how many cars were sold, so a popular year can collect more complaints. Use them to find patterns, then read the reports.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
