What a company reports and what the reality actually is are two very different things. I used to handle consumer warranty/lemon law litigation on behalf of several car manufacturers earlier in my legal career and most reported less than 1% lemon rates on new cars, but the actual numbers were much higher because they didn't count voluntary buybacks, exchanges, customer goodwill payments on known defective vehicles, etc...While not perfect, I think this Squaretrade warranty study is probably a lot more accurate:
