The VIN an owner files names the engine, which places 394 of this year’s 426 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 |
|---|---|---|---|
| 1.8 L 4-cylinder hybrid | 366 | 12% | 24% of 29 |

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. 35 complaints are not in the table: no usable VIN, an engine vPIC could not decode, or an engine with fewer than 25 complaints.
