I know those temp sensors tend to overestimate outside temp (because they usually assess temp at the road and not in the air) but mine is 10 to 15 F (7 to 10 C) high. I've never driven a vehicle in which the outside temp on the dash is so grossly inaccurate. That may just be a reality of Volvos and its not a big deal because of the weather app in SENSUS. However, I want to know whether other SPA XC60 owners also have a similar issue. I posted this question in the Facebook Volvo forum and got inconsistent answers. Right now, I don't know whether to go back to the dealer or just live with it (which won't be hard, of course).
