Does your engine look like the one in the attached picture? Many new cars have a cosmetic engine cover that would have to be removed in order to do even the simplest service. I think in your case you will have to remove 2 covers to access the spark plugs. You may need a special tool to extract the plugs. I am no mechanic but in my opinion the sparks plugs must be as shown in the picture. 3 at the back side and 3 on the front side. For a four cylinder you should have all four on the front but I think the six cylinders are staggered as opposed to being in line.
The covers are marked with red arrows and the plug in green
I hope this helps.
