My 2011 g37xs coupe was recently hit. Long story short, the body shop failed to replace a bent front left strut. I have been driving on it for a few weeks now and only recently realized the problem when it started making noise and leaking (also deminished ride quality).

My question is what else will need to be replaced as a result of this? (for example should the front right strut also be replaced)

Also what are the hoses hooked up to the strut and what is there function and what else could be damaged?

 

Anything damaged needs replacing, impossible to say what that is without examining the car. Have them check upper and lower control arms.

The hoses you are referring to are the brake line and ABS sensor cable.
