I am not knowledgeable about cars so please correct me if I'm mistaken but surely that number isn't useful unless we also have the number of models and vintages are in service? I would think Ford have way more models in play than Tesla for example, and additionally brands with a long history would have multiple years of models. I mean BMW and Ford have been building cars since before WWI and have a very wide range so there are probably at least 10 or 20 years of models that might conceivably have a recall. It's not fair to compare them directly I would think.
