CTS frame rust

I just recently bought my 03 cts. It is very clean and has barely signs of wear and tear. No rust on body but the other day I was doing an oil change and saw that where the unibody is welded to the subframe is almost completely rusted out. It is exactly in the same place on both sides, right behind the front wheels when it starts to curve up. The rest of the underbody has no rust issues at all! It is past the mileage for the rust warranty. Anyone come across this or have any suggestions?? Please help!

I just repaired mine last week (650$). I could do a hole with my finger just by pressing the rust.

The problem is simple: the ac compressor is just above the frame on the driver's side. When condensation is dropping, its dropping on the frame and gets inside from the upper part. The passenger side is okay. The rust starts inside of the frame btw.

Bad conception...

The a/c condensation theory doesn't explain both sides. I was thinking it was from road salt/deicer/whatever crap they put on the road. The front wheels kick it up and it lands where you describe the rust. The previous owner should have had it fixed under the corrosion waranty. I wonder if you have a branded title i.e. salvage. Its hard to have ignored something that bad, especially while it was under warranty. As soon as it was in the air for service it would have been seen. My 2 cents.

Its extremely unlikely, but you could have RippyPartsDepartment run your VIN through "Global Warranty Management" for any corrosion repairs. If it was fraudulantly claimed from Cadillac, it would be listed there or it didn't happen. Carelessness is the likely suspect. Or it might not have been so bad under warranty that it needed repairs, as noted above.

I just checked my Global Warranty Management printout and I have unlimited "Corrosion Limited Warranty" I don't know what 2003 had, but you'd have to do the math to see when was the last time yours was covered, and then figure out how bad it had to have been back then.

If you become certain that it should have been covered, you could complain to Cadillac Customer Service, maybe. You need to talk to Rippy. He works at a dealership and knows the ins and outs.

I have the exact same problem with my 03 CTS, but it has gone much worse, to the point I can actually put 4 of my fingers right through the frame :S.... I'm in the process of dealing with the Cadillac Headquarters here in Canada, and their consumer claims department at the moment. My local dealership took pictures of my car and the damaged frame, and passed them on to claims as well.
From what I can grasp the dealership tells me that they cannot just repair or replace a section of the frame in the front, due to the stress from the weight of the engine and such. They would have to replace the entire frame rail, which would cost thousands in labour, or if the car isn't worth it, then they'll deem it a total loss :(.... I know my car isn't worth the extensive repairs having 210,000kms, I just hope they'll come back to me with a settlement.

Have you head back from anyone yet?

Not good if the car spent a substantial time being operated in the rust belt are in a similar climate where salt was used on the roadways and it was also regularly parked in a heated garage. Those conditions would certainly have accelerated the corrosion process too.
These are definitely the reason why.
Up here this problem would not have made it through a safety check before being sold. (very strict here) I can't believe as others have stated that the service techs did not spot this. Seems strange. I just had my Old's LSS go because of similar problems too. I feel your pain!
Who did you by this from?? Can you get the vendor to make good on it or did you purchase in "as is condition"

I bought my CTS used from a Mazda dealership about 2 years ago when it had 140,000kms, I didn't buy it "as is" I was told it went through a 5-point safety inspection :s.... Over the passed two years the car has been in and out of Cadillac dealerships, and not once has anyone.. until now, told me about the frame rusting out. and its passed rusting out its completely gone :S....Its had to believe that none of these certified cadillac dealerships didn't spot it, because its pretty evident and in your face when under the car.
Still waiting on Cadillac to get back to me, crossing my fingers they are willing to help out.... but not holding my breath :/

To me, it reeks of incompetence & negligence. Hopefully you were given a written copy of the Safety Inspection Report, especially if you plan to make a formal compliant to them or even through the BBB.

Then it was passable when you got it from Mazda but I bet the rust was already started and has excelled over the last 2 years.
So either the cadillac guys never mentioned it or they took the attitude that "it's not their problem". Hope you get some help but I'm with you, don't hold your breath!
Anything can be fixed, it just comes down to how much! You may need to start hunting for frame repair people.
