- Summary
- SITUATION: An issue has been identified on certain vehicles within the listed Affected Vehicle Range which may have been manufactured away from process and, in some cases, have incorrectly mapped Diagnostic Trouble Codes (DTC) applied to the V8 5.0L S/C Petrol engine variant. Investigations have identified that the V6 3.0L S/C Petrol engine DTC mapping was incorrectly applied to the V8 5.0L S/C Petrol engine variant, which has led to incorrect cylinder identification in a misfire condition. In these instances, the engine Malfunction Indicator Lamp (MIL) would operate as normal but it would be difficult to diagnose the cylinder that is misfiring as all the misfire DTCs are incorrect, except for cylinders 7 and 8 which are not affected.
Owners of these vehicles have filed 16 complaints in the engine category.
