I first felt it at about 19k miles. Bought it with 8k. Thought I got a bad batch of gas at first but with 30k miles on it now and a scanner with live data to pinpoint what I was feeling, that obviously wasn't the case. I'm still going to trade it in simply because even though they have a fix for the issue, that's not to say it hasn't caused excess wear with the timing being pulled as sporadically and as often as it has. I drive an hour one way to work and it does it atleast every 5 minutes.Glad that it's finally being addressed. Never thought it was an issue before until y'all mentioned it.
