I purchased a 2006 cadillac SRX and the timing chain has failed twice. If anyone else have had this problem please let me know and how did you make a complaint.

For me the repair is not worth it. I paid $30,000 for a luxury AMERICAN car. Now they want me to pay $10,000 more. I still owe on the car. This has been a hard & bitter life lesson. My first american car, and my last.
Thank you for your update. Please feel free to email me with any future questions comments or concerns.

I have an 2005 with the 3.6L that has the noisy chains- no codes yet, just wondering if anyone has oil consumption issues with their V6? (more than 1 qt / 2000 miles)
Let us know how your trip to the dealership goes this week! We're available to do any follow up if you like. Please contact us via email at socialmedia@gm.com (include your name and contact information, the last 8 digits of your VIN and mileage, and a summary of the situation).

No warning, no noise, no problems indicating the timing chain had a problem. I am sick about this. I bought this vehicle because I have neck problems and the car ergonomics helped me tremendously. I was more comfortable in the car than at home! The extended warranty ended the end of November 2012 on the year basis. Is there any way to get warranty coverage? Does anyone know? None of this should be happening on GM vehicles.
I bought a used 2005 Cadillac SRX in Dec 2012. A year and a half later I've had nothing but problems. I've already had to change the coil packs and water pump, the check engine light came on with a code P0420 bank 1 which means I needed to change the O2 sensors. About a week later I starting hearing a loud noise on acceleration. When I came home my husband looked at it and found that the catalytic converters have now burnt out. To top it off the timing chains are rattling and need to be replaced before the engine blows! Its also shifting rough which my husband says may be an easy fix as long as it isn't the transmission. . . .Unfortunately Im stuck with this car since I still have 3 years of car payments left. As soon as I can i will be trading it in for something different.
Question I have is has anyone had any other problems after having this fixed.
The timing chain setup in this car is diabolically complex, and depending on where you live and on what parts they replace, the repair can add up. $2,500 does seem very high (are you in L.A. or some such zipcode with high cost of living?).
Is the car running okay? Are you getting a specific engine light/and-or code?
Keep in mind that if the chain actually brakes, that would be a disaster, so you have to do something pretty soon.
I'm just wondering out loud if the diagnosis is certain.
The other way these experts got consumers to ignore the specification was to try and use the Magnuson-Moss act and claim that all someone had to do was use something that met the specification, "or an equivalent". The problem there was that if a product wasn't approved to meet a specification you had no way to know if it really was the equivalent and the odds were greatly against it being so.
So that leads us to these last six years of these kinds of posts. Today more shops do use products that are approved for correct specification, but even now there are still hold-outs and all you need to be exposed to is someone who pushes a "Good, Better, Best" strategy and you will be somewhere that a vehicle owner who doesn't understand their vehicles needs will make a choice based on price while not understanding that the "good and better" should never have been under consideration because they usually don't meet the vehicle specifications. GM's dexos approval made selecting the right product as easy a can be and yet we still have people who through a lack of knowledge will pick up a bottle of something that a given manufacturer claims meets the specification, but doesn't get their product approved so that you the consumer can genuinely verify that it really does meet your engine's needs.
If a person does not check the oil level on a regular basis, the oil level can get very low (destructively low for the timing chains) before a "change oil" reminder even comes into play. Hence, changing the oil every 3,000 miles is like a band-aid insurance for not allowing the oil level to get to dangerously low levels before the next oil change interval, given the fact that many consumers are not that diligent in checking their oil level, especially since about all we have are self-serve gas stations.
There is also another reason I found on why these LY7 engines have a timing chain problem. Apparently the oil orifices (holes) for the timing chains are pretty small. Of course, my question to the engineers is "why so small?" As a result of the holes being so small, it is much easier for any sludge buildup (happens when the oil additives break down within the oil) to form and begin blocking up the holes, which then starves the timing chains for oil. The more mileage the oil is subjected to, the more breakdown occurs within the oil. So, when you drive on the same oil for 7,000 miles or more, it makes logical sense that the odds of more sludge buildup can occur. Here again, by changing the oil every 3,000 miles or so, the likelihood of having sludge buildup problems lessens. So, another band-aid fix regarding the timing chain problems.
GM has continued to make design changes on newer engines, but what are they supposed to do regarding these LY7 engines? Replace them? NO WAY. That would cost GM too much money. The most financially feasible approach is to simply set back the mileage change interval to (a) lessen the chance of low oil associated problems and (b) lessen the chance for sludge buildup and blockage in the small oil holes regarding the timing chains. Hope this helps regarding the timing chain frustration.
