Bulletin No.: PIP5472F Published date: 03/4/2019 Preliminary Information PIP5472F Short Duration Mis re - Rough Idle - MIL On During Cold Start - P050D Models Brand: Model: Model Years: VIN: from to Engine: Transmissions: Buick Encore 2016 - 2018 All All 1.4L (RPO LE2) All Chevrolet Cruze 2016 - 2018 All All 1.4L (RPO LE2) All Chevrolet Equinox 2018 All All 1.5L (RPO LYX) All Chevrolet Malibu 2016 - 2018 All All 1.5L (RPO LFV) All Chevrolet Spark 2016 - 2018 All All 1.4L (RPO LV7) All Chevrolet Volt 2016 - 2018 All All 1.5L (RPO L3A) All GMC Terrain 2018 All All 1.5L (RPO LYX) All Involved Region or Country North America Condition Short duration cold start rough idle, MIL on, P050D with or without P0300 at ambient temperatures between -10C and +5C (14F to 41F). Cause If the SI diagnostic fails to isolate a fuel system component concern, then one or more exhaust SHLA's (Stationary Hydraulic Lash Adjuster) may not bleed off the cold, thick engine oil, causing the exhaust valve not to seal the cylinder for a short duration during cold starts. Correction: If you encounter the P050D with misfires that occur only during the first 15 to 30 seconds of cold start, perform the P050D diagnostic in SI. If the diagnostic fails to isolate a fuel system component concern, perform the following steps. The engine Unit Number Label is located on the engine front cover. Example Engine Unit Number: The first digit = engine plant. The second digit reflects the shift, in this case 1 = First Shift The third and fourth digits reflect the model year, in this case 18 = 2018 The fifth, sixth and seventh digits reflect the day of that calendar year 026 = 26th day of 2018 calendar year (build date) If the engine you are working on was built on or after 17135, the SHLA's (Stationary Hydraulic Lash Adjuster) should not be replaced for this concern. 17135: 17 = 2017 calendar year, 135 = 135th calendar day. May 15th. If the engine you are working on was built before 17135, then replace all Exhaust SHLA's. (Stationary Hydraulic Lash Adjuster) Do not replace the intake side SHLA's as a slow leak rate on the intake side will not cause this issue. Repair Verification requires a cold start. After SHLA replacement, following a cold soak at ambient temperatures between -10C and +5C (14F to 41F) start the engine and retest for short duration misfires or the P050D.
