2012 elantra repairs
 

I have 76k on my car. Is there any common replacements I could do before I have a break down on the road?
Thanks Emmy

Buy a new car .... LOL

It is impossible to say exactly what needs to be replaced in order to avoid break down
Sometimes new parts aren't as good as the old part
And really shouldn't go replacing parts unless it is part of the tune up process.

Oh, does your car have a timing belt or chain??
If it is a timing belt then it is a good thing to change at the right intervals.
Inspect your accessory belts. Check your radiator hoses.

Well, that depends. Are you doing the work or taking it to a mechanic?

Like Avisitor stated above, make sure the timing belt is good and check all the other hoses and belts. Then I'd suggest inspecting/replacing the fluids. Brake, coolant, trans, oil, etc. Then check the brakes, tires and other suspension parts.
