Just turned over 10K on my '17, no issues so far either. Curious, how often do you drive yours...daily, 1-2x/week or ?? Reason I ask is that on another thread, someone mentioned that with prolonged sitting, the phasers may be oil-starved at initial start-up or something to that effect. I really only drive mine for fun, I use my Tacoma as my daily driver. But when I do start it after a week or more of sitting (yeah, yeah, I know...), I'll let it crank w/the gas pedal fully pressed (to prevent starting) for 10 seconds to 'prime' the lube system. Let it sit for a few moments, then start normally. So far no issues, but pretty low miles overall as well, and I'm keeping a close eye (Ear??) on their performance. No issues on start-up, no issues at WOT running up to freeway speed + maybe just a little extra...ha.
