4.0L Whistle?

SRT-4_&_Nitro said:

Hi everyone,

I've read the TSB for the 3.7L having a whistle noise come from the throttle body, but I was wondering if anyone with a 4.0L had this issue as well?

I've literally just bought my Nitro and I'm taking it in for service because it whistles under acceleration. That and the rear makes a creaking noise when I first drive it, and the front of the roof rack is cracked and warped on the passenger side. Also the exhaust has what I feel is an unacceptable amount of rust for such a new car (was a demo with 6k miles). To say that my nitro isn't making a very good first impression is an understatement. For crying out loud it's a $30,000 car, you'd think they'd have used slightly better materials.

I've driven many dodges before (mostly neons) and have NEVER had any quality issues... go figure?

Welcome!

Have not had the same issues as you, but they should all be addressable under warranty, free of charge, buy your Dealer. The salesman that drove this Nitro should have reported any issues with it to the service department, before it was put back in inventory, for sale!

I recently had my U-connect radio system up-dated thanks to info supplied here (TBS). For some reason Dealers do not seem to address TBS issues when the vehicle is in stock or in your case a Demo. They wait till it is sold! Not smart on their part, and if your Dealer's Service Department is as slow as most around here (lack of work) it would be wise to perform and correct issues on their in-stock inventory, not only for their future inventory owners, but to generate income for their service departments and their mechanics. Keep in mind that Dealers make more profit from warranty repairs, than customer pay.

Make a good record, in writing, of your issues. Give your Dealer a chance to correct them first, then if not pleased, take it back with a printed copy of the TBS from this Site, and ask them if this could be the problem?

Good Luck, and let us know how everything works out.

Here's the whistle, I placed a camera next to my front passenger tire and threw some revs to 2k. Enjoy!

I commend you on your determination to solve yours and others issue of whistling with your Nitro. It appears that no one at present has a definitive solution anywhere since I have seen your posts in several Forums. Is this only a Nitro Issue? A 4.0 R/T issue only? Have you seen or checked with 2008 Jeep Liberty owners Groups or Forums? I am sure you will prevail in your quest.

I have always told people to take their cars to their Dealership for service, after being an Automotive Parts Manager, years ago. When they reply, why would it make any difference, a mechanic is a mechanic? I always tell them first off their work is guaranteed at a Dealership, and second off 99% of the time if you have a problem they know exactly how to fix your model since they have seen it before!

Well at present you are in the 1 %, I guess.

I remember when Chrysler had an issue with their in-dash amp gauge on their New Yorker. Not only would they not charge, but most would not even start. Customers would have their car towed to a garage where a mechanic not knowing of this issue would start replacing the battery, starter, starter relay, voltage regulator, ignition switch and anything else before it ended up being towed to our Dealership. When I asked them why they didn’t bring it back to the Dealer they bought it from, they said it was too expensive! Yes it did require the replacement of the dash gauge, but it was made out of plastic and was not expensive. I even saw customers that were under factory warrant do the same thing.

Lots of strange things cause issues with cars. I remember a high squeal coming from engines with Motorola alternators that required replacing the diode package. I bet that one drove many owners (dogs too) and mechanics crazy until it was figured out! Again Dealers were the first to know and it was not as expensive as replacing the alternator that may have the same squeal and was covered under warranty.

I may be wrong but if this issue has shown up in the new Jeep Liberty I would think there may be a better chance to see a TSB issued by Chrysler as to its repair. I don’t think Nitro is at the top of their repair list at present. You did register your complaint with Chrysler as other have at Chrysler Customer Assistance Center didn’t you? Interesting to see how they respond to several complaints on the same issue! Again good luck!
