Hi all,

I have a whining noise in my 15 RT. It only happens when I accelerate.
Has anyone seen this? My warranty is almost up, less than 3k miles remaining.

Any thought would be appreciated. thank you

Check the alternator yet? That's usually it, anything whining with accelerating tends to be pulley driven. I know it's a 15 but ya never know.

The above comment^

See if you can determine the rpm it comes on at or the range that you hear it in. Unless it under acceleration throughout the rpms.

It may also be a water pump, ac condenser, idler etc. Anything on the belt drive.

It could also simply be a whistle from the air intake that sounds like a whine. Park the car and do a steady rev and see if the sound duplicates, if not, most likely something other than on the belt drive.

Are you married? Sorry :) Not coming from the audio? Changes pitch as speed increases/decreases?

great feedback, thank you both. i just installed a new mopar cai. the sound didn't change from before or after the install.
i will check the rpm range the next time i am able to. didn't think of that.

How many miles on the car? What RPM does it start exactly? Is this noise dependent on RPM's only(IE downshift to the suspected RPM's and hold it there WITHOUT accelerating) or does the engine have to be loaded, at WOT producing power for this noise to occur? Is the Whine like a turbine or gear teeth, (smooth) or is it more like a squeal, high pitched but not smooth? Does the noise rise and fall with the engine, changing with the gears or is it a slow rise independent of gear changes? Indicating propeller shaft, differential, half shaft or tire issues.

If you are asking a few thousand anonymous typists for on opinion that you are going to base your, and your families safety on, you need to be very descriptive and precise.

:::RESOLVED:::

After weeks and several attempts to troubleshoot, a resolution has been found!

Three different trips to the dealer. Here's what they tried:

-Removed my after market CAI and replaced with OEM.
Nope (I knew this but they were required to try it)

-Replaced water pump
Nope

-Removed belt, shutting down all accessories
Nope

Mechanic did some research on his own time. Found video of some car owners placing items in their exhaust systems to generate alternate sounds. When I told him that I heard the whine mostly from the passenger rear, he decided to:

-Replace passenger side exhaust
WHAM!

Something in the OEM exhaust must have come loose or freed and was generating the whining sound when getting on the gas.
RESOLVED!

Not to make light of your situation, but when that happens to me, I drop my girlfriend back home.

Edit: Now that I scroll down, I see a few guys beat me to it. :)

Well the passenger side exhaust cat back exhaust is connected directly to the x-pipe. The driver side resonator is the only part of the exhaust that can be remove at the flange. Weird, not sure how the exhaust can make a whining noise? You sure someone did not drop one of these in the tailpipe? :grin2:
