Counted from 190 complaints filed in the first three years, of 940 ever. 95% lower bound 0.87.
The model year carries far more information than the badge, so this is the comparison that matters. The bar is how many complaints each rate rests on.
| Model year | Per 1,000 | Complaints | |
|---|---|---|---|
| 2008 | 1.01 | 190 | |
| 2009 | 1.75 | 256 | |
| 2010 | 0.82 | 83 |

Failures arrive late and spread out, which looks like wear. Service history matters more than model year here.
The VIN an owner files names the engine, which places 521 of this year’s 940 complaints. Sales by engine are not published, so these are not rates and say nothing about which engine drew more complaints. What can be compared is what each engine’s owners reported.
| Engine | Complaints | About the engine or fuel system | Of those, before 30,000 miles |
|---|---|---|---|
| 2.2 L 4-cylinder | 395 | 37% | 4% of 115 |
| 2.0 L 4-cylinder turbo | 62 | 3% | too few mileages |
| 2.4 L 4-cylinder | 59 | 42% | too few mileages |
Engines as NHTSA’s VIN decoder (vPIC) reads them from the first eleven characters of each VIN. “Turbo” is shown only where every VIN records one; the decoder leaves it blank on many turbo engines. 424 complaints are not in the table: no usable VIN, an engine vPIC could not decode, or an engine with fewer than 25 complaints.

Complaint records cannot settle that on their own. They count safety problems owners chose to report to the federal government, not every repair. What they do show is how this year compares with the other Cobalt years: for every car sold, owners filed about as many complaints about the 2008 Cobalt as about the typical Cobalt year.
Among years with enough complaints to compare, the 2010, at 0.82 per 1,000 sold. Every Cobalt year, ranked.
