oilconsumpitiom in a 2011 terrain will gm fix the cars motor or not

If there is a recall, yes.
What you failed to include in your question:
The rate of oil consumption.
The number of miles on the vehicle.
Maintenance of the vehicle, I.e. was correct oil and filter used, were oil changes performed on time.

If you wish to have a GM dealer perform the “fix” at your expense-yes
