Chevrolet Malibu 2016 2017 SOP HF214702 1.5L (LFV)
Involved Region or Country North America, Israel
Condition
Some customers may comment on one or more of the following conditions:
• Rough running engine
• MIL illuminated
Some technicians may find DTC P0300 (Engine Misfire Detected) set along with a misfire
low compression in one or more cylinders.
Cause This condition may be caused by a damaged piston.
Correction Repair the engine mechanical concern based on the results of the Service Procedure
testing below.
Service Procedure
Important: This bulletin does not apply to 2017
vehicles built with VIN sequence HF214702 and higher
as they have the updated piston assemblies installed.
Repair the engine mechanical concern based on the
results of the Service Procedure below.
Note: To isolate the source of cylinder leakage to a
valve or cylinder sealing issue, it may be necessary to
remove the intake and exhaust manifolds.
1. Perform Engine Compression Testing in SI.
2. If low compression is found, perform Cylinder
Leakage Testing in SI and record the test results to
isolate the concern.
• If excessive leakage to the crankcase is
isolated, check piston and cylinder wall
condition.
• If the cylinder wall surface has not been
compromised, replace all four piston and rod
assemblies.
3. Fill the crankcase with current specification Dexos
oil (Refer to Corporate Bulletin Number
16-NA-367).
4. Check that the vehicle is up to the latest released
calibration available.
⇒ If not, reprogram the engine control
module (ECM).
An un-metered air leak in the induction system, or an
engine mechanical issue causing rough running, may
cause the ECM to learn an incorrect Throttle Body Idle
Airflow Compensation value over time.
This incorrectly learned value may cause various
symptoms to occur such as MIL on with P1101 setting,
rough or unstable idle speeds and/or engine stall.
Once the mechanical repairs have been completed,
perform Throttle Body Inspection and Cleaning in SI,
followed by Throttle Body Idle relearn and Air Flow
Compensation Reset function in GDS2.

Examples of pistons with varying levels of
damage:

4576909

Bulletin No.: 19-NA-122 June, 2019 Page 3
Examples of light vertical marks visible on the
cylinder wall:
4576902
4573920
4573921
None of the marks in the cylinder walls could be felt
with the fingernail and engine replacement is not
recommended.
Example of a damaged cylinder wall:
4576914
In this example, the scuffing is wide and has removed
the crosshatch from the cylinder wall in the area above
the arrow.
This would result in oil consumption and requires
engine replacement.
