Why Are Malibu Hybrids Suddenly Losing Power?

The Malibu Hybrid comes with a manual service disconnect (MSD) switch that mechanics can use to shut off the high-voltage battery when working on the car. That’s smart and safe. Can you imagine if that switch could just magically turn itself off while driving?

The sudden stop, the lack of power, the traffic swerving around you, new curse words you never even knew existed. Good thing that never happens, right? RIGHT?

Oh yes, it can happen. And it has.

GM is recalling some 2016 models because the MSD switch can come loose and cut power to your car while driving. The automaker points out it doesn’t affect low-voltage functions like airbags and seatbelt pretensioners, which is good when you suddenly find yourself stopped in the middle of the road.

The affected Malibus were built between 10/27/2015 and 06/03/2016.
