I just got the first scratches under the right corner of front bumper Is there any way which I can fix it by myself.
You have learned how low the bumper is compared to curbs, I would not do anyhting till your used to low level damage. My 2012 has its share, but I'm not ready to replace the entire front end cover for a few dings, tears and scrapes.
Thats all the way down to the bumper, the only way to cover it up is to get touch up paint and paint over it but your still going to have the texture of the scratched bumper behind it. Only real way to fix it is to have it repainted, especially bc its pearl white.
The driveway steep has hurt my heart. It was on the bottom of front bumper. Actually nobody will see it unless I tell t and someone also would have his knees down.
^ There you go then. With something like that, on plastic, only visible if you crouch down, I just leave them be (we have some similar "curb rash").
And, unless you move, it's bound to happen again sooner or later. I vote leave it alone. I take steep driveways very slowly, and at an angle if I can.
I'd forget about it. Short of a professional repair (not cheap), even a DIY repair with touch up paint likely won't look much better, and since you have to go out of your way to see it, I wouldn't bother. Entering/exiting the driveway slowly at a 45 degree would also be my advice going forward. It's worked for me with cars with much worse front clearance.
