If you notice that your vehicle seems to have developed a fault or is playing up, you will need to take it to a garage or have a mechanic come out and look at it. Depending on what the issue is, you may not be able to drive it so have to get it revived or use a mobile mechanic.
Unless you have a good mechanical background, it can often be very hard to know exactly what the fault is and therefore what fix is required. This is where you need to be able to find a garage or mechanic that you can trust as you are going to have to go with their recommendation as ti what needs ti be done.
If you have not lived in the area long or only just owned a car you have probably not had the opportunity to find out about the local garages. Asking on social media sites such as Facebook for recommendations is a great way to get real feedback from the community as to who is good to use. You could also ask around to friends and family as even if you have to travel a little further afield it may be worth it to know you are going to be looked after.
