16 SRT Cherokee noise on hard launch...

Ok, drove all weekend to get 500 miles on it so I could launch I once or twice, first time I just nailed it from a dead stop, sounded like a mason jar of bb's in the glove box...it's like a scaping dragging sound, if I use launch control u can hear it before u release the brake? Then it does it pretty much thru first gear, almost sounds like a diverter valve on the exaust or something? Idk? I was a tech for Chevy and Mercedes for years, never heard anything like it before...kinda got me concerned after paying $75,000 for it!!! The very last thing I wanna do (and doubt I would regardless) is take it to the dealer and let them do 125 hard launches in my new jeep...any thoughts would be appreciated.

Could it be a loose heat shield?

Re: 16 SRT Cherokee noise on hard launch...

I had a very similar noise. Go down a curvy freeway on ramp and see If it makes the same noise. My problem ended up being a cracked motor mount, under heavy acceleration and high G turns to the right I had that god awful noise.

I figured it out...it was the little brace that bolts under the exhaust...under load the pipe was vibrating against it...put a washer in between brace and body...problem solved.

You wouldn't happen to have pictures do you? Mine is in the shop now after only 350 miles and I'm not sure the dealer is going to figure it out...

Re: 16 SRT Cherokee noise on hard launch...

I had that same problem when I had my 2015.

Ended up being the whole catback system. Ordered a new one and it went away

Did the dealer pay for the replacement?

Of course. lol

These rigs come with a 3/36 bumper to bumper warranty.

And if you are past the mileage and you have an extended bumper to bumper, its covered.
