Does a mobile mechanic void your warranty?

Every new-car buyer hears it: “You have to come back to us for servicing or the warranty is void.” It’s one of the most common questions I get from Wanneroo and Perth drivers. The short answer: no. A qualified mobile mechanic can do your logbook service without wiping manufacturer warranty cover, as long as the work follows the schedule and uses the right-spec parts and fluids.

What the law actually says

Under Australian Consumer Law, a manufacturer can’t force you into dealer-only servicing just to keep warranty rights. Independent and mobile workshops can service the car. What matters is that the service matches the logbook requirements and that you keep proof of what was done.

What “done properly” means

That means the correct oil grade, filters and fluids for your model, the inspections listed for that interval, and a clear invoice or service record. Skip steps, use the wrong oil, or leave no paperwork and you create risk — not because the mechanic was mobile, but because the job wasn’t to spec. Same rule applies in a big workshop.

Logbook, without the dealership queue

Westcoast Automotive does mobile logbook servicing across Wanneroo and Perth metro. You deal directly with Ryan, get an upfront quote, and leave with documentation that keeps your service history clean. Handy when you’d rather not lose half a day at a dealer.

Keep the cover, skip the myth

If a dealer told you only they can touch the car, ask them to put the warranty threat in writing — most won’t. Book a proper logbook service with a qualified mechanic, keep the records, and you’re on solid ground.
