Today I'm driving a loaner truck as my beloved 2019 Titan SV is in for repair. Two weeks a go the truck went in for its first service at 5000 miles, the chief mechanic discovered some oil residues, while he suspected that it's remains from the factory he asked that I keep an eye on it. Yesterday I noticed some small/dried oil puddles that were never there before. Took it into the dealer today and early report suggests it's the oil cooler. They've reassured me that it's minor and expecting to have the truck back with me early next week.
