I have owned my crossfire since 14,000 miles. It is a 2006 limited. It currently has 23,500 miles.
I have noticed a few strange noises.

-First, When I turn my A.C. on above halfway on fan speed, about 50% of the time, my A.C. makes wierd buzzing electrical sounds. The sounds seem like the originate somewhere behind my vents. The sound goes away as soon as I lower my fan speed to the 1 or 2 chunks.
-Related to this, I was recently showing off my car to a mercedes mechanic who was surprised to see an SLK block in a chrysler, when he pointed out that my antifreeze A.C. line was "sweating". He said that it could have a small clog somewhere in the line, and I should get a mechanic to check it out. He said if I do have a clog, they would then syphon my antifreeze out, removing the clog, then re-inject the antifreeze.

-Second, my car makes a whining sound when idling in drive gear at stop lights. I also notice the sound when I am creeping the 1st and 2nd gears. I always passed the noise as normal car noises, (like loud driveshaft freespin on 350z when in neutral) but lately I have grown worried that this may be the timing belt straining, or not situated correctly. I only hear the noise inside the car. When changing the oil, some spilled from the filter housing along the timing belt. I cleaned it up the best I could but I am wondering if this oil could be causing the sound, or even wearing my belt prematurely.

-Lastly, I have noticed this sound since I owned the car, a quiet high pitched wistling coming from (I think the exhaust) at around 70 mph. I only hear it when I am cruising and giving it only enough gas to maintain speed. As soon as I accelerate, the sound goes away.

Has anyone experienced any of these issues? If so, can you help calm my fears or tell me what I need to do to fix them? Thanks!

 

Not sure about the various noises, but the engine uses a timing chain, so it should be no problem until you near 200,000 miles.

 

Is the whine constant or on/off. Could just be the secondary air injection (pretty loud). I have the MT and it does have a nice tranny whine but not at idle/low speed.

As far as the AC thing does it make the same noise if the car is not running just "on"? May be easier to track it down without the added engine noise.

 

To timing belt sound- I meant the alternator belt, whichever one is in the very front of the engine, right behind the radiator.

To whining, I only really notice it at around idle and acceleration, though it could be there at higher speeds, I just can't hear it due to road noise and engine noise. the sound seems to go in incremants of sound then a quick loss of sound. Then it will pick up again. Repeat cycle. closest sound I can compare it to, is perhaps a belt winding up.

To a.c.- I have only heard it when I was driving. I just tried it now and it didnt make the noise at full blast. But that could be because it is fairly cool right now, or because I only hear it everyonce in a while.

 

I have had my Chrysler Crossfire for going on 3 months now and am noticing the "whining gear" noise. Definitely not something I wanted to deal with but I am about to go to the dealer to use my warranty. I was wondering if anyone may have some tips on dealing with the dealership. What kind of questions or schemes do they use to say the warranty doesn't apply for whatever reason? Any replies would be greatly appreciated!

 

Noises? I just turn up the stereo. End of problem.

 

Honestly I don't know. I purchased my car used 2006 model. So I have no experience with warranties or the like. What I did notice, is that after I changed my oil, the noise greatly decreased if not went away. I think I will change my oil more regularly now. As for the 80 mph whitling sound, I just increase my speed to 90 and the sound goes away
