Do I have to go to the dealership for repairs to keep my warranty?
No, you don’t have to use a dealership for servicing or repairs. As long as a licensed mechanic uses parts that meet manufacturer specifications, your new car warranty remains valid in Australia.
What are the signs that my car needs mechanical repairs?
Common signs your car may need mechanical repairs include strange noises (knocking, grinding, or squealing), warning lights on the dashboard, reduced fuel efficiency, rough idling, or trouble starting. Other symptoms like vibrations while driving, delayed gear shifts, or a burning smell can also signal deeper issues with your engine, transmission or electrical systems. Ignoring these can lead to more costly repairs down the track, so it’s best to have your vehicle checked by a qualified mechanic as soon as possible.
How much do mechanical repairs usually cost in Australia?
The cost of mechanical repairs in Australia can vary widely depending on the type of repair, the make and model of your vehicle, and local labour rates. Minor repairs, like replacing brake pads or spark plugs, might cost a few hundred dollars. Larger repairs, such as engine or transmission work, can run into the thousands. Getting a clear diagnosis and quote before work begins is key. Some mechanics also offer mobile services and labour-based pricing, which can help reduce costs if only minor work is needed.
