Record by record
12 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.
Work done
How it is said to have ended
- result not stated4
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.

Normal Transmission Shift and Throttle Response Delay
1Fault
- A sag or hesitation may be noticed when coasting at low speeds of less than 24 km/h (15 mph) with a closed throttle and then aggressively applying the throttle.
- With an automatic transmission, after a hard complete stop with a closed throttle immediately followed by an aggressive throttle opening, the downshifts may not be completed by the time the throttle is opened.
- A sag or hesitation may also be noticed while cruising at highway speeds and then aggressively increasing the throttle, forcing a down-shift.
2Finding the cause
Possible causes
- In this maneuver the throttle blade is opened slowly for up to 0.7 seconds, even though the accelerator is applied aggressively, to help minimize driveline lash and clunking.
- As a result, approximately 0.5 seconds of zero torque may be commanded to allow the shift to first gear to occur.
3Correction
Caution
- All of these conditions are a result of Torque Management and should be considered normal; no repairs should be attempted.

Winter Fuel Grade Use in Warm Months 2020 – Drivability Issues
1Fault
- Fuel smell
- Loss of engine power, no acceleration
- Stalls or shuts off
- Warning light
- P0300
- P0171
- P0174
- P228C (general documents only)
- 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.
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.
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.

Open the manufacturer’s document (PDF) ↗ The points above were read from this document.
- 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.
