NHTSA Complaint #11404166 — 2012 MAZDA MAZDA3

THERE HAS ALWAYS BEEN A MASSIVE VOLTAGE DROP WHEN SLOWING DOWN OR LOWERING SPEED. HAPPENS CONSISTENTLY IN ALL DRIVING CONDITIONS, HIGHWAY/CITY, NIGHTTIME/DAYTIME. THIS LEADS TO ALL INTERIOR LIGHTS AND MORE IMPORTANTLY, HEADLIGHTS DIMMING AND FLASHING WHENEVER THE ENGINE SPEED DROPS. THIS OFTEN MEANS AT NIGHTTIME WHEN GOING AROUND CORNERS VISIBILITY IS NEARLY ZERO UNTIL THE LIGHTS COME BACK ON AFTER A FEW SECONDS. ELECTRICAL SYSTEMS ARE ALL FINE WITH INSPECTION. UPON GOOGLING IT, APPEARS TO BE A COMMON PROBLEM AND SOFTWARE RELATED.
