Service bulletin N212326940
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Customer Satisfaction Program. Certain vehicles, may have a condition in which the engine oil cooler (EOC) lines may leak and detach from the crimp joints. Exposure to cold temperature may also aggravate this condition. If the EOC lines leak, there may be an oil leak on the ground and if the EOC lines detach while operating the vehicle, there will be an immediate decrease in oil pressure. This will coincide with a warning on the driver information center display (?Oil Pressure Low Turn Vehicle Off?), along with warning chimes. If the customer continues to operate the vehicle, a loss of propulsion is possible. Dealers are to replace the engine oil cooler lines, oil, oil filter and refill the coolant.
