Any updates?

Anything yet? I can't take much more of this ticking.

Hi everyone!

I am having the same problem. Glad I came across this thread! I have an early build 2008. It was like it when I bought it, having already been to a dealer for unsuccessful servicing.

I am going to bring in the car in a week or two.

Here is what I wrote on my paper for my Caddy dealer:

=====
Ticking Noise coming from back of engine compartment, in front of middle of dash.
Rate of ticking occurs slightly at idle, increases with RPMs, even while vehicle in Park.
Mont Pleasant Cadillac thought it was the timing cover (there is a TSB) but it was not that.
They are sure it is the fuel pump, Part #12626234, but it is backordered.
Over to you...
======

Any further insights, etc, that may help point my dealer in the right direction?

Thanks!

From your description, it certainly sounds like it might be the high pressure fuel pump. I believe it is located at the rear of the engine in front of the driver.

Still have the ticking noise. Its not as loud now because the weather is warmer. The dealer said there is nothing they can do because they have no TSB to work with. They said its the nature of the high PSI fuel pump on DI engines. Corp doesn't know squat either. This is my first and last DI engine! Very annoying and embarrassing for having a luxury car.

[Michael 514]

Wow.

I just read the other thread about this!

I cannot believe that the ticking is 'normal'. Perhaps we are talking about different types of ticking or varying degrees of loudness, depending on the build date/batch of the high pressure fuel pump.

I am starting to get a little annoyed, because before I bought the (used) car, the Chev dealer told me to wait a week to come see the car, because it has a bad ticking noise, and he'd rather get it fixed beforehand, before I came to see the car.

Then after a week, he told me about the fuel pump being on back order from that Caddy dealer, but that I can come to see the car, and just bring it in to my Caddy dealer for the fuel pump, after I buy it.

This ticking noise is quite pronounced, and extremely annoying. I don't think it could be normal. It also happened when it was hot outside this weekend. I showed off the car to two car buffs, and they both knew something wasn't right.

My girlfriend said there's no way a $50,000CAD car could sound like that.

I guess I won't jump to any conclusions.

I will tell you this, fellow forum dwellers... If indeed this sound cannot be muffled, I am going to attempt to resiliate the contract of sale, and return the car. I will also accept a substantial price reduction. Although these types of contracts are not my area of expertise, I happen to be an attorney, and will not hesitate to exercise my rights as a consumer, against misleading or incorrect statements by a professional seller.

Again, the GM sales rep was SO adamant about trying to get it fixed before me seeing the car, that it would be remarkable for him to want me to accept it the afterward as normal.

Very interesting....!

I will keep you all posted!

My 94,95,97 vettes all had the ticking noise all the time and it was rpm dependent. My neighbor; a GM/ Corvette field rep said it is the nature of the fuel injectors, they just can't make a mechanical device that does that much work, silent. On my 99 vette they added a lot of sound deadners and it became barely audible. I suspect Cadillac has done the whole engine shroud to quiet the fuel injectors, fuel pump and anything else from the engine bay. I know it must be annoying to those who want a dead quiet car, but in the total realm of things that could be wrong, this one just isn't too bad. Try adding a whistling D3 airbox, or a high performance exhaust then you'll never hear the ticking anymore. I suppose it's a matter of what noise bothers you and which ones don't. Just don't condemn the whole car line to bankruptcy for a mere annoyance.

[Michael 514]

I would never condemn the whole company to bankruptcy for the sound of the fuel pump. I will, however, condemn the company to bankruptcy based on all the other creaks and rattles in the car , along with the lackluster service at two local Cadillac dealers.

It's amazing how poor the service was. I called GM and complained. The dealer was not happy!

It's just so funny to compare and contrast GM's P.R. (How many "you are special!" mailings/brochures/emails did I get as a CTS 04 owner?.... and funnier than that... I just love that list of 10 silencing features GM mentions in their press release, measured against what the cabin/sunroof/dash really sounds like.

Bottom line, it's all about managing expectations.

If you're going to send out PR clips about 15 breakthrough noise dampening features... and mailings about just how amazing I am to be part of the Cadillac family, well, the company should follow through. Ditto for the Chev salesman from whom I bought the car. Had he said, "Notice those ticks? That's the high pressure fuel pump, prevalent in all DI engines. Please consider it before buying.." then I would NEVER complain. But he clearly said numerous times that it would disappear. So imagine my slight 'panic' to be in this situation.

In any case, no use jumping to conclusions! Let's see what my local Caddy can do with the noise! Perhaps all will be solved. Let's give GM the benefit of the doubt.

I did want to wait before bringing in the car for my first servicing, because every day, depending on the weather, there are more things added to the list.

For starters.... Condensation in one headlamp after rain; passenger mirror doesn't move left or right; Passenger mirror gets stuck in reverse mode; driver's window has an awful squeal when closing; the rubber trim around the engine compartment keeps coming loose; the sunroof rattles more than it should; the passenger seat ventilation is quite loud.. louder than the driver's seat; and a few other things.

But I will "close up" the list, and make an appointment today.

In addition to all the PR, I also think my expectations were higher, because my 2004 CTS pleased me so much more (despite the plastic dash! )

I'll keep you all posted about what I learn about the ticking noise!

[exm22psu]

Nicely stated, Michael 514. Let us know how it goes . . . I have the stuck mirror sometimes in reverse mode and my driver's side mirror "shimmies" on the highway, but none of the other things you mentioned . . . also to be taken care of eventually . . .

Hi guys!!

I am soooooo ANGRY at my Cadillac dealer!

I brought the car in on Monday with a list of 12 issues, and got a call from them today.

Sure enough, as anticipated, the morons at my dealership confused my ticking noise with TSB 07-06-04-025.

I explained to them the following (already typed up for my meeting with the service manager tomorrow)

===========================
1. When I was interested in purchasing the car, Dyson & Armstrong said not to come this week, because there is a bad ticking noise coming from the car.

2. After one week, D&Y explained to me that Montplaisir Cadillac noticed the loud noise, and established it was the high pressure fuel pump, Part #12626234, but it was on backorder, therefore I could come buy the car and bring it to my preferred Cadillac dealer

3. During the test drive, the sales manager, Mr. Billy Evans, repeatedly informed me to ignore the ticking noise, and we commented on how annoying it was, but to overlook it.

4. I was specifically informed that this is not an issue with TSB 07-06-04-025 (Document ID 226-3327). This TSB deals with ticking and clicks during (a) cold start; (b) is more evident when around the vehicle, or (c) when the hood is open, and (d) it lessens once the engine is warm. The present TSB also indicates that the fuel pump will (e) continue to tick at a lower rate of approximately one tick per second during idle.

5. My issue occurs (a) throughout the drive, cold/warm, even after driving for three hours (b) is not evident outside the vehicle (c) is not heard when the hood is open, (d) does not lessen once the engine is warm, and (e) never ticks at a rate of one second during idle.
===================

I just spoke to the sales rep where I bought the car, and to the technician from that other Caddy dealer who tried to order the fuel pump.

They were both FLOORED that my dealership said this was normal.

Well, I am ready for a fight tomorrow.

GTPprix... do you have ANY information that can help point my service dealer in the right direction??

Thanks!

PS Some excellent news, though... The dealer managed to fix my washer fluid cap that keeps popping off, and they managed to properly affix the rubber seal around the engine compartment that keeps flopping off. Awesome! Great technicians!

I just heard from a friend, that he came up with a simple solution to the noisy fuel pump. There is a thermo shield that was used on Corvette engines to isolate some component; he couldn't remember which. It is a piece of insulation material backed by a silver thermo barrier material. He got a piece similar to this from the local parts store. he neatly wrapped the fuel pump insulation side facing the pump and secured it with nylon wire ties. No more noise. Once again, the back yard mechanic comes up with an inexpensive solution that the dealers and factory have missed.

[Michael 514]

This is great information. Thanks!

By the way, after several phone calls and lots of waiting, I FINALLY sat down with the dealership manager.

We pulled in a red CTS DI next to mine. He was in it, then I stepped in it, too.

The first thing I said was, "Is it on?"

It was sooooooo quiet.

Then we went into mine.

They still have a hard time believing that the TSB in question doesn't apply to my ticks.

Unreal.

But I am just happy both the manager and the technician heard the noise!

I'll post more when I get the car back!
