    Default 2019 Sa low voltage warning

    Our 2019 Supra SA 400 had low voltage warning message running at 3500 rpm Message said bring rpms up to 1500. Anyone else had this issue?

    The 2019 moombas and Supras changed to a new alternator, there is a known wiring issue at the alternator, your dealer will fix it.

    Thanks. It was a bad altanator. When voltage is low they replace it and if voltage is high it's the harness is what service reported.

    In the Moomba forums it was recently discussed that 2019-2021 should be running on both sets of batteries (1+2). I guess this is referenced in the owner's manual.

    Here is link to one of the several threads:
