There are autosar specs well defined for CAN,LIN,Ethernet. Why are these specs unavailable for UART and I2C? Is UART and I2C not used in automotive?

Automotive has some unique safety requirements and it would be hard to implement them in such protocols as UART or I2C.
They are not used by the auto industry for inter-ECU communication and therefore they are not part of the standard.

Correct. As per AUTOSAR no specs are mentioned for the I2C. So if you want to write an I2C, you can write in CDD layer.
