Chevrolet Cobalt: Best and Worst Years by Complaints
Comparing the 3 Chevrolet Cobalt model years from 2008 to 2010 that have at least 25 NHTSA complaints, and allowing for the era and for how long each year has had to collect complaints, no year has clearly fewer complaints than typical, and none has clearly more. This reflects NHTSA complaint data only.
This comparison uses only NHTSA complaints, recalls and investigations. It is not a reliability verdict: complaint counts are not adjusted for how many cars were sold, and complaints are unverified consumer reports. An open NHTSA investigation is shown separately; it is not a finding.
All Cobalt years compared
Score 0–100, where 50 is a typical Cobalt year: complaints relative to all vehicles of the same model year (which allows for the era and for time on the road), weighted for crashes, fires, injuries and recalls and for how early the problems appear. Model years 2008 to 2023 with at least 25 complaints are compared; newer years are too new to compare. Methodology
