The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Record by record

6 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

How it is said to have ended

  • result not stated1

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

    Winter Fuel Grade Use in Warm Months 2020 – Drivability Issues

    1. 1Fault

      • In rare instances customers may complain of a fuel smell, longer starts, hesitation and, in extreme cases, engine stalls.
      • Any combination of DTCs P0300, P0171, P0174 and P228C may be set.

    2. 2Finding the cause

      Possible causes

      • Using winter fuel in summer weather may cause drivability concerns.

      Steps to confirm (in the document’s order)

      • The concern should not be a single event but multiple occurrences associated with hot days.

    3. 3Correction

      Caution

      • No repair is required; the vehicles are not damaged and will recover.
      • There is no other remedy until summer fuel and/or cooler weather is available.

    Remedy
    This Preliminary information communicates the use of Winter grade fuel during the warm months of 2020 and the potential rivability issues that it can cause. The ongoing Coronavirus (COVID-19) pandemic has caused significant reductions in driving and fuel use.  Due to the surplus of winter grade fuel sitting in storage (pipelines/stations) the EPA is waiving the fuel vapor requirement.  This will extend the use of winter fuel into the summer months. The drivability concerns should not be single events but should be multiple occurrences associated with hot days.
