So I just purchased a one-owner 2013 V6 Premium with leather and the shaker sound system and I LOVE it. It only has about 20,000 miles on it and drives great... so far.
Yesterday I was taking someone for a ride and I put it into sport shift mode and did 0-50 letting it automatically shift or by pumping the gas at about 6k RPMs. Well after the shift into third gear all of a sudden the check engine
light starts flashing. It threw me because I'm used to flashing CELs meaning engine damage. I pulled over and turned it off and back on and it was fine.
This has happened 3 or 4 times now, 3 of them I know where in sport shift mode, though I'm pretty sure the 4th one was also. They've happened at different speeds and different gears. The last time I was ready, and I ran a vehicle health report and looked at the information system check in the dashboard control center and everything came back OK - WHILE the CEL was flashing...
Also, the last time it happened, I kept driving it and noticed lack of power when I pressed the gas. After about 30 seconds it went off and I was able to resume driving. This is what it has been doing.
Now, I've researched this quite a bit, and I've found SEVERAL posts that sound exactly like this issue. From everything I'm reading, the issues I'm reading about are a result of misfires. Apparently, there's a TSB out about it and I just need, what, a crank shaft retiming and a PCM reflash? The only problem I have is that EVERYTHING I've found is for the GT. I found literally more than a dozen posts about this and I did all the research, but I have not been able to find even One post about the V6 on any forum.
My question is, does this sound similar to the problem that the V8s are having and if so, has anyone heard about this happening with the V6? Since the computer doesn't store codes for 15 second flashes and since vehicle health reports are coming back clean, I don't have much to go on here, and I know if I go to the dealership, they won't be able to replicate it and will tell me everything's fine. Just trying to figure out what to do here.
