The OG teslas had FOMOCO e-throttle pedal assemblies from Ford.
The problem is that Tesla is constantly changing parts during a model run, sometimes for the better (reliability, simplicity) other times for cost cutting and that is why I’d never own one. Because there are a million iterations finding parts to repair them, and I only buy 10+ year old cars (possibly nothing after 2010 at this rate).
Teslas are built like one time use smartphones. Only good for parts recycling after they fail.
