Official summary
Certain vehicles, equipped with a 1.4L engine, may have a condition that could cause the turbocharger to fail. If this condition occurs, the Malfunction Indicator Light (Check Engine Light) will illuminate, and a diagnostic trouble code will set. Additionally, the engine may run rough or have reduced power. Dealers are to replace the turbocharger as necessary. The repairs will be made at no charge to the customer.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
