I bet your right as I saw Hyundai salesman go over a 2013 Sonarta Hybrid but didn't show the window sticker year.I swear I saw this review earlier in the year and it was labelled 2012, not 2013. Now I can't find it. I have a feeling he changed the title to get more views.
I just had my 2011 KOH in for about a dozen TSB services yesterday, and noticed that the car is a bit more responsive after leaving the shop, but I will hold off judgement until I drive it some more and report back. The jerking & jiggling also irritates me as my only major compliant with the car.I think the review is spot on. We now have had our Optima Hybrid a year and it still jerks & jiggles in the lower speeds. We love everything else about the car but the drive train is still unrefined. Kia please do another software update. While the previous TSR's have improved it but only about 60%. The car needs it!
