CTS Sport Wagon - questions for owners

Hello everyone!

I'm considering picking up a used Cadillac CTS4 Sport Wagon (Not the CTS-V Wagon...I wish...) and I've got some questions for owners of these beautiful cars.

Long story short, I'm thankfully in a position where I may be able to get a fair chunk of cash for my current vehicle, and I've always loved the second-gen CTS, and the Sport Wagon even more so. I'm an average dude who's honestly just kinda tired of driving my orange toaster (a Jeep Renegade) and having a driving experience that lacks any form of enthusiasm, and the cards might be right for me to indulge a little in doing something different for new daily driver.

I'm surprised, when searching them out, that they are surprisingly affordable given how rare they are, and that even high-mileage examples are in seemingly great shape in a lot of cases. Some even appear to have pretty thorough service records.

About half of the wagons for sale have the 3.0L V6, and the others have the 3.6, and I've been told by about half the folks I've talked with to avoid either engine, almost evenly, as one is supposedly more reliable than the other. I'm aware the 3.6L can have timing chain issues if not properly maintained, but have there been significant issues otherwise with either engine?

Many of these wagons are also sitting at or just above 100,000 miles. At a firm I previously worked at, the owner of the company had a 2010 CTS sedan with the 3.6 that he got 295,000 miles out of, with it being a generally reliable, low-maintenance vehicle until around 250,000 miles, when it began stacking major issues upon major issues. It's my understanding that it was running when he sold it, but needed likely $6,000+ worth of work, so he offloaded it cheap to someone who was interested in it. A few people I've talked to have told me they have anywhere from 90-150K on the odometer with almost no issues, and I've had others say the cars are absolute money pits that cost $3-5K per year to keep on the road. I 100% understand there will be maintenance costs on older cars, so I expect to have to have things worked on here and there, but I've found that the testimonials from people I know personally are generally positive, and the ones on the internet much less so.

Is there a general rule of thumb when it comes to when to walk away from a potential deal on one of these cars? Are they generally really that expensive to keep on the road? I'm just getting a lot of mixed opinions, and I totally understand they're used cars and at the mercy of their previous owners and the environment. Are there typical issues to keep an eye out for such as electronics issues that are less reported but growing in frequency due to age?

Just looking for some insight as to whether or not it might be a good idea to consider one of these beautiful machines as my next car. My intent would be to hang on to it as a daily for about 5 years and either garage it afterwards or replace it, but I honestly drive pretty gently and don't really abuse my cars. I also only drive about 10-12,000 miles per year, with about half my driving being on the highway.

Thanks!

Both the 3.0L and the 3.6L use the same timing chains. However, there was a batch of bad (possibly faulty heat treatment) chains used in the 3.6 LLT in 2008 and 2009 causing premature wear and failure. I don't know whether the 3.0L also received the same bad batch of chains, but there seems to be a lower incidence of chain failures on these engines. There is also a lower incidence of the 3.0L engine being installed in the CTS in general. For some reason they're common in the wagons.

If it were me, I would strongly prefer the 3.6L DI for the improved power. But it's your car, so follow your preferences. One should expect to replace the timing chains on the LLT engine as part of regular maintenance around 130K to 150K miles, with the infamous bad batch of chains failing significantly earlier. The later LFX engines have chains that last a little longer, but I would never advise attempting to run a 3.6L V6 to 250K miles without one timing chain replacement. Really, I wouldn't do that with any engine with a timing chain.

I've only had mine since December, but so far, so good. It's a 2012 Premium with the 3.6 engine and AWD... which worked quite well during the recent bouts of snow.

Comfortable, hugs the road quite nicely. Mine has the intermediate FE2 suspension, a good compromise between comfort and handling.

3.0 vs 3.6... I drove both. Both are a bit sluggish coming off the line. The 3.6 develops pretty decent punch as engine speed builds, while the 3.0 doesn't. It's a 4200 pound car after all. I'm averaging 20mpg in mixed city/hwy driving. There doesn't seem to be much difference in gas usage between the two engines.

I was pleasantly surprised by the average condition of CTS wagons for sale... definitely better than most cars of the same age/mileage.

Got mine in Diamond White paint, very pretty, a metallic pearl white. Other colors that really stand out are Diamond Black, Red Tintcoat, and Opulent Blue.

The cam chain situation: the pre 2012 LLT 3.6 engine could have an issue, as the cam chain could lose lubrication and stretch if the oil level got low (but not low enough to trigger a warning light), and the LLT had a crankcase ventilator that was too big, sucked a lot of oil, and consequently, the engine could consume a lot of oil. There was a fix for this by Cadillac, a valve cover gasket that cut down on oil consumption, and the issue was engineered out of the 2012+ LFX engine.

Out of over 40 carfax reports for 3.6 wagons I looked at on the carfax used car site, only one CTS wagon showed a cam chain replacement. A 2010, at 70k miles, sounds like a low oil situation. So this doesn't seem to be a very frequent issue, though the generally better care that CTS wagons seem to get might be a factor.

As these were made in the early 2010's, electronics are a bit dated. Didn't recognize my old iPhone 10, or current Galaxy, though you can put mp3's on a thumb drive and play them. There are 3 sound systems: base, 5.1 surround, and 5.1 surround with nav and a central screen. As the climate controls are built into the sound system, installing aftermarket electronics isn't necessarily a simple operation.

I got the nav system, and DVD-Audio discs will play in it... if you can find them. I just picked up Dire Straits Brothers In Arms in DVD-A from Amazon, remixed for 5.1, and it sounds fantastic.

Have patience... due to the limited number of wagons for sale, it can take a while to find what you want, and you may have to either buy remote or travel some distance.

Finding it is part of the experience.
