Record by record
11 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.
Component named as the cause
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.

Manufacturer communication2005–2006 GMC YUKON ・ 2006-10-01
Intermittent stall, misfire or crank no start: Ignition 1 feed wire broken near C148/C149
1Fault
- The engine may intermittently stall, misfire, or crank without starting, and there may be no trouble codes set.
2Finding the cause
Possible causes
- The pink Ignition 1 power feed wire may break inside the insulation near connector C148/C149.
Steps to confirm (in the document’s order)
- Complete the SI diagnostics first; if they are inconclusive and the concern can be duplicated, inspect for a loss of Ignition 1 voltage to the ignition coils.
- Wiggle test the ignition coil harnesses to see if the concern can be duplicated.
- Inspect splices S160 and S159 for loose connections, and connectors C148 and C149 for wires breaking near the connector.

Fuel Rail Crossover Tube Retainer Screws Recall
1Fault
2Finding the cause

Not stated
What the documents say to do
Engine fuel rail crossover tube retainer screws may break (5.3L RPO L59) - recall 04V-376Confirm
- Check for leaks: ignition ON with the engine OFF for 2 seconds, ignition OFF for 10 seconds, ignition ON with the engine OFF, then visually inspect for fuel leaks.
Repair
- Dealers inspect the fuel rail crossover tube and replace the retainer screws if necessary.
- Hold the fuel crossover tube retainer to the bracket on the fuel rail with locking pliers, using enough force to keep the retainer from moving without damaging any parts.
Caution
- The GM bulletin lists Tahoe and Yukon models because Canadian vehicles are included in the bulletin.
Read the sentences of the record
- Cause
- On certain vehicles, the fuel rail crossover tube retainer screws were not manufactured to specifications and may break. If a tube retainer screw breaks, fuel could leak from the fuel rail crossover joint, the engine may stall and, if an ignition source were present, an engine compartment fire could occur. Correction: Dealers will inspect the fuel rail crossover tube assembly and, if necessary, replace the two tube retainer screws.

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.

- 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.
