My 2011 with 195,000 miles that never gave me a problem finally bit it. Engine suddenly started shuddering and threw a PO301 code. The next morning the coolant level was a couple inches lower in the expansion tank and was running rough. I limped it to the dealer and got $2000 for it on a trade in on a new Hyundai Sonata. No regrets, it was a great car. Don’t drive enough anymore to justify paying the premium on a hybrid.
