A few years ago we purchased a new 2016 Charger R/T and a new 2015 Challenger R/T + from a local dealer. Both had an issue with Sirius dropping out in 3-4 locations around town. If we drove fast enough through these spots there were no interruptions. Well, we've since sold the Challenger, but my wife still has her Charger and the problem and she wants it fixed before warranty runs out. I assuming both cars had the same audio systems. Before we take her car to the dealer I'm wondering if anyone else has/had a similar problem.
