This. Title is trash and another trash YouTube video with an attention grabbing title.
Falling is a little harsh because they're still #3. But its more of a drought of newer vehicles that sounded the alarm. IMO, they've kept their current buyers happy to keep their sales position despite their dropping marketshare (dropped for two straight years, 2016-18), but the need for better refreshed products to sell to conquest buyers and bring back previous owners (They are there) is becoming more apparent.
according to your link, Lexus market share is up in 2019.
I mean, this is getting repeated every week, topic seems to be beaten to death.
Their choice of doing ES and UX before another large suv and IS is already vindicated by 2019 being the best sales year worldwide.
I would guess that 2020 was supposed to be the weaker one, with refreshed IS and LM (China only) but then with covid-19 that wont be noticed at all, you will have IS then best seller NX coming out as soon as anything else from anyone else.
Basically, if their "struggling" year is one that got them record sales, what the heck will happen next year? Cha-ching for Mr Toyoda.
