Deceleration whine

Hi everyone.

I have a 2014 GC SRT in melbourne, Australia and while I love the car it has the dreaded deceleration whine that I have read about before on these forums. Basically once the car is warmed up if you are coasting off the throttle you can hear a loud whistle/whine type noise that disappears the instant you apply any throttle or when the car slows to very low speed.

It had the problem from new and after the car had done around 1500km I took it in to the dealer. A technician went out with me for a drive and noted the noise. I left the car with the dealer and they called me back to say they couldn't reproduce the noise on the dyno. They said they were going to contact Chrysler in America and would get back to me.

They never did. After about 5 calls to the dealer I gave up. Meanwhile the noise seemed to be reducing in volume so I thought hey lets just give it some time.

Now the car has 8500km and the noise is worse than ever. I just find it infuriating and it is ruining my enjoyment. I'm locked into a finance agreement but I don't think I would ever buy a jeep again if they can't fix this.

I read on this forum that some owners in America had front prop shafts changed and this fixed it but it seems this was last year and I can't find any updates. Can anyone confirm this for me? I am planning to go back to the dealer but I want to be armed with knowledge about the problem first.

Many thanks to anyone who can help

Adeel

Re: Deceleration whine

Mine did that too amongst the bumper popping out, hard shifting, exhaust leaks connect issue, steering issue etc.....and got rid of it. Chrysler (Jeep) dealers I went to both wanted to not do anything to fix any of my issues. I just could not take being ignored for paying that much for a vehicle. Will never buy a Chrysler product again. Back to Ford.

Re: Deceleration whine

Hasn't anyone had the propshaft changed? I thought there would be at least a few of you that could tell me about your experiences! I have my car booked in with the dealer in a couple of weeks. I hope this propshaft is the answer and I can get it sorted. Otherwise I'm getting rid of the car and cut my losses.

Re: Deceleration whine

Update. Well I had the car checked over by the dealer. They acknowledged the noise the first time booked it in a month down the line for a check by a "srt specialist". When I turned up a month later I dealt with someone completely different who seemed to have no idea of the previously agreed plan. Anyway they checked it over again (obviously no srt specialist!) and...found no fault.

But at the same time the car was serviced and lo and behold it's much better since. It still makes the noise after very hard use but in day to day driving seems ok now. So I get to keep my sanity.

Although I'm still annoyed at the quality of the dealer experience and the fact that I seem to have some sort of lemon (no one else has this problem in Oz???) it's acceptable now. I would lose so much money if I tried to get rid of the car now so I will just keep it.

I probably come across as some whining retard but I'm just glad it's a lot better now.

Re: Deceleration whine

Seems like it might be normal for an AWD vehicle. The transfer case in my WRX was quite loud and letting off the gas is usually when you hear gear whine.
