Usually it is ok that you follow the the user's manual to do service (e.g. 8000km or 6 months whichever comes first, depends on your model and brand). For some items, you may check it yourself frequently, e.g. tire pressure.
You only have your car for one year and I assume your car warranty is between 3-5 years, depends on the car, in that case, you should visit your dealer and while they are servicing your car, they will be able to fix or replace defective parts for you as it is under the warranty.
One more reminder. If your vehicle is new and in warrenty, you must go to dealer regularly for service as required in the user manual. Otherwise your warrenty will be broken.
