: WARNING!! Neucleus "X2i Ipod Interface is a POS

12-23-08, 06:31 PM
I have learned the hard way
As many may have read my other posts, I am new to this forum, and a new owner of a 2005 Escalade ESV Platinum.
The previous owner had installed a “Neucleus X2i” Ipod Interface unit.
This interface module hooked into the XM radio box behind the glove box.
I later found out he did not make all of the right connections for it and it screwed up the audio for the Rear Seat Entertainment system.
I later solved that issue by hooking it up properly.
I was happy since the Ipod worked, and the Rear DVD audio worked over the vehicle speakers.
So, I saw my Service Engine Soon (SES) light came on 5 days ago.
Since I had also the steering wheel clunck problem with the Intermediate steering shaft TSB, and now the SES light I decided to take it to the Caddy dealer to get both problems solved.
The dealer kept the truck for 2 days and kept saying they were having problems communicating with the truck’s computer.
They even replaced the Powertrain Control Module (PCM), the main computer, to try and solve it. After 2 other phone calls, I immediately drove to the dealer and told them about the Ipod interface in the truck and told them I wanted to remove it to see it solved the communication errors
It took me 2 minutes to yank it out.
WALA….their programmer now works with the truck!!!
The SES light ended up being a bad fuel cap.

So to make a long story short, don’t put a “Neucleus X2i” Ipod Interface unit in your Escalade.
This POS caused the dealer 6 hours of crazy errors and got me a new PCM module for free, since the truck has less than 80,000 miles. Cadillac replaced the PCM under warranty.
Cadillac also replaced the intermediate steering shaft under warranty also, so I am now happy.

Forum member "shore" warned me about this unit, but I thought all was OK. I know better now.
Thanks "shore"

I read and read about these units.They can cause electrical gremlins.

I'm more curious as how you have a warranty still.

I was under the impression that my 05 with 70k was out of warranty.

Is some of it still covered?

They told me that the steering wheel cluck is a huge problem on all GM trucks 2002-06. He said that they have so many that Cadillac is now covering them under warranty.

And for the PCM module, he said that was covered for 80,000 miles.
I did not argue with him on that. Since they had replaced it, and it did not fix the problem, they left the new one in the truck. However, they wrote the ticket showing that the PCM fixed the comm errors to get it covered by Cadillac.
My 05 ESV has 64,000 miles and I have no extended warranty

I am lucky. The POS neucleus X2i got me a brand new PCM for free.
I am going to try and sell it on EBAY for $20

Here is the history info for my VIN #
See the bold items.
As you can see from the claim history, the previous owner also had the steering shaft replaced at 31156 miles.
That may have helped me get the warranty on the steering shaft replacement today. The same Cadillac dealer did the work back then.

Explain the steering wheel clunk more to me.I do hear/feel a noise like a clunk but it feels like it is more outward from the bigger wheels when turning and going over a bump or rougher pavement.

Remember THIS THREAD (http://www.cadillacforums.com/forums/cadillac-escalade-ext-esv-forum-1999/156080-i-feel-slight-knocking-steering-wheel.html)?
That was my first post after purchasing this truck. I talked about feeling a "knocking" in the steering wheel at slow speeds, like in a nieghborhood.

You told me it was my front differential.
That was not the case, but instead the steering shaft.

If you feel and hear a slight knocking in the steering wheel when you are driving slow and turning on rough pavement, then you have the issue.

Here is the TSB Info.

Steering - Clunking Noises Felt in Steering Wheel
Bulletin No.: 00-02-35-003M
Date: January 31, 2007
Clunking Noise Under Hood and Can Be Felt in Steering Wheel and/or Steering Column (Replace Upper Intermediate Steering Shaft [I-Shaft] Assembly)
GM p/n 19153614.

2002-2006 Cadillac Escalade Models
1999-2007 Chevrolet Silverado Models (Classic)
2000-2006 Chevrolet Suburban, Tahoe Models
2002-2006 Chevrolet Avalanche
1999-2007 GMC Sierra Models (Classic)

2003-2006 HUMMER H2

This bulletin is being revised to update the repair procedure with a permanent fix. Please discard Corporate Bulletin Number 00-02-35-003L (Section 02 - Steering).
Some customers may comment on a clunk-type noise coming from under the hood that also can be felt in the steering wheel. These conditions may be more noticeable when turning at low speeds on rough road surfaces
Diagnostic Tips
Use the information below to help diagnose the source of the noise.
Frame Snap and/or Popping Type Noise - A frame snap or popping type noise can be duplicated on rough or smooth road surfaces with steering wheel input to the left or the right. This type of noise can be HEARD and is typically louder with the windows rolled down. For additional information, refer to Corporate Bulletin Number 03-08-61-002F or newer - Snap/Popping Type Noise Coming from Front of Vehicle (Remove Front Crossmember, Change Fastener Orientation).
Intermediate Shaft Clunk - Intermediate shaft clunk is heard and FELT in the steering wheel and/or steering column area, typically while driving on rough road surfaces with steering wheel input.
I-shaft P/N 19153614 has been designed to replace previous designed dampened and non-dampened I-shafts. The physical difference in the yoke size will accommodate all vehicles listed in this bulletin.
Due to the design of the new I-shaft, it is not possible to lubricate/grease the I-shaft.

Well dang maybe that is what it is.I never really noticed it with the stock wheels on it but after the 22's I heard and felt a slight thump.Turning into my driveway was when I noticed it.Then I started feeling it when turning in parking lots that where not smooth.Almost like something was a tiny bit worn/loose.I'll make an appointment or just run by there and drop it off.

I do remember the thread on it.At 1st I thought you might have a front diff that was binding.

Definitely have them check it out and show them the bulletin info.
Make sure they use the "M" bulletin, which is a new shaft design, part number listed above.

I felt the difference before I left their parking lot.
The steering wheel is smooth as ice now with zero knocking or cluncking.
It is a major improvement for me and thanks to Cadillac, I paid nothing for it.

Boy this thread went off topic.
I hope everyone else sees this steering shaft info.
