Hi, I have the same exact car to help solve the steering wheel squeak I used wd40 in the crack where the wheel turns also
down where the steering column goes through the floor. I didn't use much but it did work it out. This fix lasts about 2 months.
The real fix involves a steering shaft removal and lubed. My chevy also has this problem. also hyundai has the issue also.
Hope this helps you out I know its annoying as heck.
