Mercedes-Benz MBUX Owners Report Sporadic CarPlay Dropouts - A Persistent Bug?

By [Staff Writer] | March 2025

A growing number of Mercedes-Benz owners are reporting a puzzling and frustrating issue with the MBUX infotainment system: CarPlay connectivity that works intermittently, then fails without warning – even when using a wired connection.

8-58, described a particularly erratic experience. After a system reset, wireless CarPlay stopped working entirely. Then, wired CarPlay – which is typically more reliable – also failed. Without any action from the driver, wireless CarPlay mysteriously returned the next day. During a single drive, the system connected, dropped the connection, then reconnected again.

This on-again, off-again pattern is new; previously, the car either recognized CarPlay at startup or ignored it for the entire trip.

” No single fix has emerged, though some owners have had temporary success with a full factory reset of the MBUX unit. 8-58 as of this writing.

The bottom line: If your Mercedes frequently loses CarPlay mid-drive, you are not alone. The issue appears tied to the MBUX software stack rather than your phone. Until Mercedes releases a patch, a manual re-pairing or a system reset may be your only workaround.
