My Audi Q5 2013 3.0T has 55k miles - should I be nervous about the next 50k miles?

It is true that some imported vehicles - such as Audi and other German makes - can develop issues as they age which will cost some money to repair. But there is no way to know. The question you ask is a personal preference -- seek the guidance of a local repair shop to check our vehicle out and maybe give you a sense of its condition if you are concerned. www.repairpal.com/repair-shops
