01-002/222022-04-05. Service bulletin. FUEL SYSTEM, GASOLINE.

Depending on wind direction and/or parking environment, the odor may be more noticeable. The odor may be caused by evaporative gas from the gas outlet vent.

01-003-18-34212018-05-07. Service bulletin. ENGINE; FUEL SYSTEM, GASOLINE; POWER TRAIN. Some customers may experience a lack of power with no warning lights illuminated and no related DTCs stored. This concern most likely occurs when the fuel temperature is high and during situations where high power is required. This concern may be caused when the learning value for the low pressure fuel pump exceeds a certain level and the PCM limits engine power to avoid a lack of fuel injection. Even if the low pressure fuel pump has a problem, no DTCs are stored. To eliminate this concern, the PCM control logic has been modified not to limit engine power. After this modification, DTCs P0192:00 or P0087:00 are stored when the fuel injection amount is insufficient. P0192:00 - High fuel pressure sensor circuit low input P0087:00 - High fuel pressure sensor circuit range/performance problem.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
