Would your 2005 rear right turn signal be covered by warranty The car is 14 months old and you have a 5 year 100000 km Powertrain Warranty?

No, the rear right turn signal would not be covered by the Powertrain Warranty. The Powertrain Warranty typically covers major components of the drivetrain, such as the engine, transmission, and driveline. A turn signal is not considered a major component of the drivetrain and would therefore not be covered under the Powertrain Warranty.
