Simon Da Osam Paul Report post Posted August 18, 2016 (edited) got 2015 Mondeo Hybrid (also known as Fusion). It has developed (after 7000 miles) very strange rattling sound, which sounds like relay sound. Usually appears on roundabouts/bends.video attached. my car has fitted Adaptive LED lights. any idea what it could be?

Simon Da Osam Paul Report post Posted August 18, 2016 Is it your Adaptive LED lights moving on the curves?they do, but in this case, adaptive lights are off - DRL lights are ON (DRL - Daytime Running Lamps)) also, it happens only occasionally, while lights move all the time. So, 99.9% of the time, when lights are on, there is no such sound. Quote Share this post Link to post Share on other sites
