GM had a recall on their Epsilon extended platform that didn’t fix the problem either. Wires would corrode due to no seals and proximity to HVAC. Safety systems would go off line, brake lights would get stuck on. A Colorado woman actually drove off a mountain because of this defect.

Still not fixed to this day, as the correct fix would involve replacing a computer module in millions of cars with one that has a weathertight interface. US automakers always get the laziest of passes.
