Why is my car loosing all power go down the highway

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. A loss of power that coincides with the loss of electrical functions - such as dash lights and displays - as well as power assist concerns sounds like it could be related to a broken drive belt. If the drive belt is broken, the power steering pump will not turn, causing a loss of power steering. Multiple warning lights will illuminate due to a lack of electrical output from the charging system. It's an educated guess - but there could also be a different cause, such has the battery not providing adequate power, allowing electrical systems to malfunction. Hands on testing is needed, and it seems like the vehicle is not suitable for driving until the concern is resolved. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
