Filing in context

For scale, 1,330 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 6 months.
Defect
Due to inadequate manufacturing process controls for the intake duct on the direct-injection turbocharged engine, some ducts were produced using a material that does not conform to specification. Over time in service, these ducts lose oil resistance and heat resistance, allowing cracks to develop. This causes engine malfunction and, in the worst case, may result in engine stall.
Corrective action
On all vehicles, verify the manufacturing lot number of the intake duct and replace any affected duct with a conforming part.
