Band new Trailhawk Renegade with ~ 550 miles. When driving at a steady throttle input at about 30 mph a grinding noise starts and then it appears to go away as you speed up, you can actually feel it, like very faint rumble strips. The noise remains when I put the transmission in neutral and let the car coast. Sometimes it will stick around and give a grind down sound as you stop. end quote
mine started after remapping at the dealer at the 30 -39 MPH I get the rumble then when it starts I move the shifter to the manual shift of the auto trans and it goes away not sure if it is a factory fault or something else but that's how I stop the noise...

Anyone try to get this flash yet just for the 30mph whine/grumble? I haven't had the time to badger my dealer yet.

they have had it for 5days and the rascal is behaving tomorrow they will try the Flash as advised by the NTHS people if not gone will be super upset

Faint rumble strips is a good description. The wife and I called it a low frequency hum. Nonetheless it took them forever along with multiple trips in for the tech to replicate the problem even though we felt it immediately. After a back and forth with the engineers they replaced the rear diff. Diff motor goes with the whole unit as we. Noise went away entirely. That was late 2015. With an off the boat date of 4/15 (forgot actual build date) we're on our 3rd diff and possibly a transfer case with an entirely different sound.. something much more horrific!
4WD is unavailable and now functions as a 2wd vehicle. Severe grinding sound when slowing or sometimes rough roads. This noise happened back in November over a year after replacing the diff the last time. So they did it again even though it wasn't the same noise or ultimate outcome as the first incident. Now it's March 2017 and it's back again with that same horrific noise and no 4wd. This time.. dude says it's the transfercase. My theory is that something there could be blowing the diff and that it will need both as there was a shaft broken off in the diff the last time. There is a star case with this reoccurring driveline issue however the 64,000 dollar question is at 40k is it still under the initial claim or is it under out extended warranty which in that case they only cover days of rental.. it's been there almost a week now

Greetings Sports Fans....I had a non MOPAR Mechanic check out my motor mounts top and the lower right strut and it turns out they were both bad and upon replacing engine mount and strut mount I am happy to say no rumble .... I noticed that they updated the mounts both upper and lower the thing interesting my Trail-hawk had the new strut and the Latitude had the old one, go figure all four replaced IF you have a rumble check your mounts instead of the flash-fix it will be easier also google the mounts Summit has the mounts by Anchor and MOPAR website also has them non rebuilds and I saved some coin on the mounts and getting them installed Good luck everyone PLEASE CHANGE YOUR MOUNTS THEY ARE BAD
