Not that I've seen, but when the news media stopped the hype the complaints seem to have slowed down as well. Toyota recalled one model for an accelerator pedal that was subcontracted out. Ford and Nissan both reportedly use the same component, but they didn't recall it. Lots of smoke, not much fire. One report showed that Toyota unintended acceleration events happened at the same frequency (based on car population numbers) as other manufacturers. So, there may never be anything to find.
