    My theory is that the lifter was bad and fell off right away. The reason I think this is when I zoomed in on the picture I see what appears to be the number 15 on the cam lobe which I circled. This would have been worn away and the lobe shiny like all the other ones are. I couldn't see any numbers on any other lobes.

    This is the lobe next to the one with the variable lifter. It appears to have a lot more wear and even seems to have a scratch. In conclusion, if you have an affected car, your lifter is probably already fallen off and you just don't know it. This is purely speculation on my part though.

    I dodged the Honda oil dilution issue because my brother (a mechanic) warned me against new engines, so I did research I would not have otherwise done (I was relying on the CR-V popularity.)

    I dodged the Mazda CD issue only because life issues got in the way when car shopping in the fall of 2018. When I picked up again in February, the turbo had been released. But now there are folks talking about the turbo occasionally not working in certain weather conditions. Like you, I read a lot on these sites and independent reviews, and did not see any major negative issues (except the SCRM paint, which is easily avoided by making a different color choice).

    This is not like buying a $50 drill that does not perform properly. You get much better customer service when spending way less money. And even if you have to eat it, it's only $50.

    A car is not so easy to get out from under...and it ain't cheap. It's this lack of sufficient relief that spikes the angst.
    Yep, Toyota recalling the 2019 Ravs with trans problems, Subara with valve train problems...it's like the late 70s early 80s all over again, car manufacturers putting out crap.

    Wait, I did see Toyota has issued a recall for 3,400 of its 2019 Corolla Hatchback models in the U.S. due to the torque converter problem in its CVT which could fail and result in the loss of power.

    So what's the problem on 2019 RAV4 with its 8-speed transmission?

    I can't find the place where I saw the RAV 4 trans being recalled, maybe a mistake, discount that for now. Anyway, numerous problems and complaints with the 2019 RAV4 transmission with rough shifting.

    I don't think I've ever seen a cam lobe with anything imprinted or just printed on them. All have been smooth.
    Not to say that it's never been done, but the finish on the cam lobe surface is almost as critical as the bearing surfaces.

    I don't think it is as critical with roller cam followers as it was with the old sliders...
