The short answer: no — when it's fitted properly.
It's a fair question, and the honest answer is reassuring. The Autowatch Ghost connects to your car's CAN data network without cutting or splicing the original wiring. Because the installation is non-invasive, it doesn't interfere with your manufacturer warranty.
Where worry sometimes creeps in is with the quality of the fit. A rushed, untidy installation by someone working to a price can introduce problems — and that's a workmanship issue, not a flaw in the product. It's the very reason approved, professional installation matters.
As an approved Autowatch Ghost dealer, I fit every system myself, integrated cleanly and registered properly, so you've genuine, warranty-safe protection and a record of authentic work. If you've any concern specific to your make and model, ask me before you book and I'll give you a straight answer.
