#2798 of 2880 2008 Cadillac CTS Electical Problems
Jul 12, 2011 (10:54 pm)
I have owned my 2008 cadillac for 5 mths and I have taken it to the dealer 5 times all Electical problems replaced driver window motor, amplipher, some brake bracket (IDK), passenger side window won't defrost, door lock would not release, and just picked it up today for the rear defroster. I love this car just not committed to having a relationship with Cadillacs service department. It sucks that I lost my hard earned down payment.

Maybe he didn't make his payments and the repo guys got it.

Sorry it's taken me so long to respond. I had the problem a few months into owning the car.
I took it to Moore Cadillac in Chantilly, VA for wind noise in the sunroof and the speakers. The service advisor told me that I didn't tell him the right noise to look for, needless to say I am never going back to Moore Cadillac. They had my car for 2 days and never fixed a thing. I also had to pay taxes for 2 days on a rental car. Completely ridiculous. Lindsay Cadillac in Alexandria, VA are excellent and have helped me with other issues. I gave up on the speaker issue though. I heard it again this morning. It's when some songs on the radio have more bass than others the speakers rattle.

All OEM speakers do that at a specific frequency, which is why people who have their stereos loud all the time are probably going to want to install a subwoofer to keep the regular speakers from ratting themselves lose from their mounts over time.
Fixing it is usually as simple as taking off the cover or getting into the trunk, putting a lock washer on the bolts/screws holding it in place, and adding a drop of low-strength (not permanent type) loc-tite.
As for the wind noise, all sunroofs eventually do that as the gaskets distort and age from the repeated cycling between hot and cold during the day. Also, the tracks and mounts on these extra-large panoramic sunroofs can sag and distort a bit with age, just like, say, your doors will from wear and tear. The "fix" is usually a small amount of black gasket sealer at the right location - usually it takes just a thin painted-on layer not much thicker than a 3x5 card in a couple of inch area. It might take you a long time to figure out the exact location, though. Sometimes you get lucky and can feel a hole or gap with a piece of paper or similar. Sometimes you have to just get a bit lucky.

I had a GT Mustang for 10 years and never had my speakers rattle like this and of course the system in a mustang is much less quality than a Cadillac (I would think). I also heard others with a similar issue (the dealer said people were complaining about it). I would think a Bose system would work better than that. I'm not blaring my radio, it also happened on just a normal talk radio station so there's something definitely wrong with the way the speakers are installed or some casing around it that's causing it to rattle. It's not a big enough deal to keep getting it checked out for though.
The sunroof was leaking, the drain pipes were clogged so once they unclogged them that fixed the leak issue, but they must have broken the seal in the meantime. This wasn't a normal wind noise, it sounded like the door was open. They fixed the problem though with a new seal like you said, so I was happy
The first year of owning my 08 CTS I had the timing belt replaced too which isn't a normal wear and tear item it was a known problem. There are definite defects in this car, which is understandable since 2008 was the first year the newer body style was out. I just didn't expect to have this many issues with the car this soon. I take care of my CTS and love it so I don't want to see anymore major issues wrong with it. I'm worried I might need a new exhaust if the new hangers they installed don't work over time. I guess I'll keep the car for now

I have an '09 CTS. I don't have the problem with the speakers rattling, but I doubt it is a better system than your Mustang GT. It does have the Bose name and I think highly of their at home systems. I am not sure that their car systems are any better than anything else.

One thing about the CTS to be aware of is that the oil life sensor in them is half as sensitive as it should be. It's a known problem and most mechanics recommend changing the oil when it gets to 50%. If the oil additives fail, the engine has a tendency to eat its bottom end. Since synthetic oil has no natural anti-wear properties, there is no margin for error once the oil fails.
Change the synthetic every 6K miles or 6 months. Don't let it go lower than 50%. It costs twice what normal oil does, but at half the frequency, it equals out.
