Bulletin Summary
Region Letter: The involved vehicles are equipped with an engine oil cooling system. The oil cooling system could experience a small leak due to a manufacturing issue. If a vehicle is continuously operated with this condition, it may result in abnormal engine noise, illumination of the Malfunction Indicator Light (MIL), and an engine oil level low message. Over time, an oil pressure warning message may be displayed on the multi-information display and/or a buzzer may sound.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
