Horrible sound when accelerating....

Lately I've notice that if I am at a dead stop and punch the gas, I get this absolutely horrible grinding noise from under the car. It doesn't sound good at all. I'm guessing it has something to do with the transmission. It doesn't make the sound if I punch the gas while already out of first gear. I'm going to see what the dealership says but thought I'd see if any of you had this same experience. Thanks.

Re: Horrible sound when accelerating....

Yeah, sounds like something you'll want to take to the dealer for.

Are you sure it's not the ESC/traction control kicking in? I've had this happen twice and it sounds like very rapid clicking. For me the noise came from the front left of the car but I imagine based on what wheel(s) are slipping that would vary.

I wish it were just that but this sounds like metal on metal. Almost like a rock in a garbage disposal.

Did you ever fix this problem? Because I believe I have the same issue.

Re: Horrible sound when accelerating....

Mine sounds like this if the wheels slip. I think it's the traction control engaging. Usually happens when I punch it turning left out of my driveway when the road is wet.

Re: Horrible sound when accelerating....

I guess the true test would be to turn off traction control and get on the gas from a stop to see if you still hear it.

Just don't do it anywhere you'll end up in a ditch if the back end comes around on you.

Re: Horrible sound when accelerating....

I have a 2014 Hemi and I have the exact same sound. It's metal on metal grinding/vibration.

See this TSB for our problem.

http://www.wk2jeeps.com/tsb/tsb_wk2_1600213.pdf

I'm convinced this is what is wrong. However, I'm having trouble convincing my dealer this is the problem with mine because this TSB only covers build dates before March 16th and mine is March 22nd.

Do you have a Hemi and what's your build date?

Re: Horrible sound when accelerating....

Well so far its been a horror story, my cars been with the dealer for over 12 days because of manufacturer defect paint on my bumper and fender. So I also asked them to please take a look at the rattle, at the moment I have been getting very impatient and only had the car for a little less than a month. So far after tons of research and constant forum searching, it can either be the drive shaft or U Joints. I really do not have the patience to hear the dealer say some bs to me saying there not able to find it, or thats normal bs.

Re: Horrible sound when accelerating....

Shortly after my original post, I took it to the dealer and they said they couldn't replicate the issue. It's now getting worse and seems to be doing it even without heavy acceleration. I'm dropping it off next Monday to have them look at it again. If they say they can't replicate it again, I will make them get in the Jeep with me to show them. I'll keep you guys posted on what I find out.

Re: Horrible sound when accelerating....

Sounds like time to make a video with your cell phone and record the noise.

Re: Horrible sound when accelerating....

I will here in about an hour. I hate trying to replicate the sound because it's so horrible and I'm afraid I'm doing more damage.
