Look, I get you're unhappy and I don't doubt you had a bad experience - but you're blowing things out of proportion. I've owned two 2014 QX60s. Test drove a third. Had 2017 and 2018 QX60 loaners. Not a single one that I've driven or owned, has had any problems. Design quirks? Sure. Crappy entertainment system? Oh yeah. But "they don't care about people and someone will get hurt" flaws? Not any of the ones I've been in. I love mine, and I feel very safe putting my family in it. It's why I keep it - I drive a convertible for other moments. But my kids ride in the QX60. My friends are begging me to sell them my car because they like it and feel safe in it, and they had twins.
Lastly, and this is just me being pedantic - even if you were 100% right in what you're saying - this is NOT the thread to say it in.
