Re: Jeep feels like it is struggling around 1-2k RPMs

I have tried 89 octane like they suggest, as well as 91. It didn't make any difference. The condition occurs no matter what brand or octane of fuel I try.

Re: Jeep feels like it is struggling around 1-2k RPMs

I am having the "fish bite" problem with my 2011 Grand Cherokee (Hemi) and my garage/dealer says there is nothing they can do about it. This really bugs me since I know the problem is quite common from reading forums. Does anyone know if Chrysler has put out a bulletin/fix for this yet?

Chrysler has put off the update to Q1 2014.

They have also now excluded the 2011s. Make sure your dealer documented it on a work order and you have a written copy of this complaint.

I can not believe the performance of this vehicle. The so called "fish bite" issue with this vehicle is horrible. The vehicle sputters and tugs while driving between 35 and 65 miles per hour. I have had it in the shop three times for the same fish bite issue and everybody starts out denying the issue until you push and prod them into admitting that this problem has been known for a long time now. Chrysler, it seems, has promised a fix for the problem for a year now. They originally told me by August 2013 and as of Sept. 27 still nothing.

It is hard to believe that Chrysler treats customers this way. If you are considering buying a new JGC, I strongly recommend against it. I asked if the new 2014 was any better with the new 8 speed transmission and the service manager told me it was actually worse than the 2013.

Interesting, I have not seen anyone with this concern on the 2014s at all. Trust me we see every problem imaginable... Anyone here have this issue with a 2014?

Yoma, also just a quick question, have you tried running mid-grade fuel for a while in your Hemi? I have the 2011 Durango with this problem I ran premium for a while then switch back to Mid-grade and it is much better. To my knowledge if you have a 2012 or 2013, there is still a fix coming. The updates are always late but ask anyone with the 2014s, reported problems have been seeing updates and resolutions.... Again never heard of this on a 2014.

This is BS I have a 2014 5.7 and it does not have the fish bite issue nor have I read about anyone else having it on here.

I have driven a number of the HEMIs in the 2014 as well, but I also know my experiences don't always apply to everyone, so I was checking.

Thanks JP,

I'm glad you found the Jeep Garage. It's refreshing to see someone who's first post is a slam of the product, followed by inaccurate information.

Re: Jeep feels like it is struggling around 1-2k RPMs

Has anyone with the problem tried a new set of plugs gapped on the tight side of the spec ? Moderate load (but not enough to get into PE) and low rpm in a high locked up gear is classic particularly if it clears up when you push down on the gas pedal far enough to invoke power enrichment.

I have no complaints about the drivetrain on my 2014 Summit V8. Way more responsive than my previous 2012 Overland V8.

I haven't had to dig in to any problems on a Hemi (haven't owned one - yet), but modern engine computers usually store information about how they're running and adapt to what you feed them. The behavior you saw could have been from needing to let the computer "learn" that you were giving it higher-octane gas so the higher the octane the faster it learned. If so, you could probably shortcut that process by clearing its memory or forcing it in to quick-learn mode.
