Can't blame that on a part!


LOL Good, that's really comforting...


Either way, thanks for the reply!

Misfiring Issues

So I've been sitting on my recall notice for Amy, my 2013 R/T, about a month or so because, well, I didn't want to deal with it.

19johned53 I see why the P01 was extended into '13, as that's the old style part that we all were told was replaced with the aluminum unit.


Thanks for posting this.

born2rock I picked my 2013 Challenger from the P01 today. Mine was build September 2012, I have nearly 60000 miles on it, but I've disabled the MDS with Intune at 30000 miles.

Dealer showed me the old tensioner they've replaced, it was the white PA version stamped with 6/2012. It had no visible wear.

08blackrt My car had, I think, 43K on it when it was done, it had no signs anything was wrong, but it was just about ready to go. It didn't seem any different at all after it was done, and the only way I know anything was changed was the water pump was cleaned up and they showed me the chain. I don't think I'll ever get used to that flimsy looking chain that's on most engines now. I remember the Cloyes roller chains I put on a couple of my engines in the past. No worries about them breaking.

19johned53 Thanks for the update, and that's great to hear.


The "tug" went away when I had the P01 done on my '10. Keep us posted on yours.

FWB I picked up my R/T today after the dealer performed the P01 campaign. The car never had any issues with the timing chain, although there was a slight "tug" when the MDS was active at times.

Surprisingly, the guide that was taken off my car was the complete black plastic guide. I thought this was the original design (not being one of the updated parts) and assumed my car had the revised guide from factory? My car was built on October 2012.

The '13s were only recently included in the campaign so I assume FCA figured that the guide might not have made its way on to the late 2012 build cars.

I thought I'd share this in case it might add some information to this thread.

Also checked engine oil (was replaced by the dealer) and coolant (replaced NOT reused) and they were both on spot. Car drives exactly the same with no power loss issues that a few have suffered here after the recall being done due to the timing being a bit off. I will listen to the engine more carefully when it gets into MDS mode to see if I still have the "tug".

Hats off to FCA for fixing this issue

EDIT: The tech said that there were no signs of wear on the guide (I believe he just said that without inspecting and not to have me worried). The guide was on the table and I couldn't take a very close look at it to check for wear signs.

In addition, my car currently has about 41,000 miles on it.

I'm gonna have to somehow find the time to take it to Seattle to get it looked at as that is the closest competent dealer from what I've been told. Dealers here suck. But, I'll do what I have to, to get someone to listen to me.
With the high turnover, maybe it's more the dealership's fault than the service managers'.
