Cadillac needs a gas/electric hybrid like the Lincoln MKZ Hybrid. I recently bought a 2011 MKZ Hybrid. Very nice, but it does lack a few features my former '05 STS has, such as: 1. You need a key to unlock and start. There is a keypad; however, it is really nothing more than a backup way to unlock in case for some reason key is locked inside. I have to physically lock door because it does not have automatic door locking system and no fob that allows easy access; 2. THZ audio system is not as good as Bose; 3. I like Cadillac's navigation British lady who gave me driving direct

Put a new radio in my 08 CTS now it won't start
MAC replied to sethc1020's topic in General Cadillac Forums
By the way, maybe the problem is the amplifier. Did you try removing positive and negative battery cables and touching them together to reset electronics? This was one suggestion I read about radio problems that may or may not work. It seems to me that your best bet is to try to figure out what the problem is with the original radio. -

Here is a link to a website that fixes Cadillac OEM radios. Cadillac Bose Amplifier / Speaker and Stereo Repair Here is a link to same website's homepage: Factory Car Stereo Repair, Inc. I suggest you call and/or submit a request for a quote to see if your radio is one that can be fixed. It may be something minor. No power and glitching out may be nothing more than a defective switch. You will never know unless you give it a try. -

I would see if the radio can be fixed. When the dealership told you the radio was no good were you given a specific reason? Was there a trouble code, such as a communication code or something that could be related? -

I'm not sure what the problem is with the original radio but here is a link to a short discussion about the 2008 CTS radio and one possible fix. It seems the best way to deal with this situation is to fix the radio. -

2005 cts 3.6 engine

Below I quote information I found regarding the 3.6L CTS engine, which says it is indeed an interference engine: -

If radio fuse is removed and then reset anti-theft, maybe it will start. Below is a procedure I found for resetting anti-theft: 30 minute GM relearn procedure: 1-Turn ON the ignition, with the engine OFF. 2-Attempt to start the engine, then release the key to ON (vehicle will not start). 3-Observe the SECURITY telltale(this is the security light), after approximately 10 minutes the telltale will turn OFF. 4-Turn OFF the ignition, and wait 5 seconds . 5-Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes (the vehicle is now ready to relearn the Passlock(TM -

I did some research on this topic. From what I saw, it appears that intermittent radio and/or loss of navigation indicates a problem with the radio or a problem with one of the pins at the harness. I will see if I can find it and post either a link or quote it. But one person said that it was narrowed down to a faulty pin at the harness connection.

I haven't tried adding upper engine cleaner. I have used Marvel Mystery Oil figuring it may clean internal parts including rings. I also did a bit of research and someone said 15W40 did not increase oil pressure--at least anything worth noting. As far as 20W50, that may be a different story?
-
If it's better to use 10W30, then I will use it. I just want to curb oil burning and hopefully oil leakage. I am now looking to maybe buy a STS AWD-V8. I have been looking for a few months. But I have said that I want to run and run the STS I have until it can't run anymore. But the V8 Northstar in it just keeps going and going. If I solve the oil leaking chances are oil use will be cut quite a bit. I just haven't had the time to get underneath and see what's going on with oil pan bolts--maybe they are loose. Then again, oil leaking is a problem with these cars, so it is likely that I

I drove almost 800 miles over Labor Day and, so far, no issues. Thanks Jan. I will probably use either 15W-40 or 10W-40 during winter.

I decided to give 20W-50 oil (Mobile 1 Full Synthetic) a try in my '05 STS. I'm dealing with leaking, plus no doubt burning oil with almost 300K miles. I know that some will tell me that I am looking for trouble; however, my high mileage engine no longer has tight tolerances, so this heavier weight oil should lubricate. The oil pump should handle it. I recently put in 4 quarts of 15W-40 and it seemed to me the car ran better. Probably less oil burning helped? I will see how it goes, particularly if I have to top off less. Between oil leaking and burning, I was topping off too much. In f

V8 Northstar 2005+ models
MAC replied to Mr Slimm's topic in Cadillac CT5, CTS, STS 2005+, 04-09 SRX, CTS Sport Wagon (Sigma)
Traction control is very sensitive--actually, too sensitive, in my opinion. It can be downright dangerous on roads that are not smooth because hitting a rough patch during acceleration will cause traction control to engage causing brakes to engage. Many times I have been annoyed by traction control. I would not be surprised if a bad mount would cause traction control to engage since engine hop would likely effect suspension and trick the computer to think something was going on traction-wise. -

I have almost 300K on my '05 and it runs real good. However, there are issues as follows: 1. Oil leaks; 2. Power steering pump is susceptible to failure (A pain to replace but a home mechanic can do the job); 3. Rear differential bushing will eventually fail causing clunking sound, which means it must be replaced. 4. This particular design can eat batteries due to too much heat since it is placed at the rear near at the passenger side firewall. I finally insulated the battery after going through 3 of them in about 4 years. 5. If you have different size front and rear
