    I’m in the market to buy a car. I’ve been thinking of getting the second gen CTS for a while now & I’ve been saving to do so. I’m a female who’s not really that into cars & I’m wondering what year is the best to get, & likely to have the lowest amount of issues. I kno maintenance & fixing it is...

    Hello everyone, this is my first post here \:D I have a 2011 CTS performance and I'll start by saying that my car was already the UQS non-nav 10-speaker system, (so that saved me a lot of work), and I successfully swapped in the popup navigation radio. I'm doing this write up because while the...

    Hey guys I just purchased a 2015 CTS 2.0T AWD with low miles. Love the car so far but it is my first Cadillac and I'm learning but don't know all that much about then. My question is has anyone put an aftermarket exhaust system(I see there's not alot of options) or changed their mufflers? If...

    I have a 2007 Cadillac cts with a 3.6LV6 with the more expensive transmission option. I bought it knowing it had timing issues, just not how bad the issues were. The engine no longer runs whatsoever and I'm sure the mechanic I took it to made everything worse because they didn't put the engine...

    2014 CTS4 2.0 luxury I’m trying to narrow down if the problems I’m having are coming from the center stack, or HMI module. Do you guys have any insight? Here are the issues They MAY NOT be related to each other, but I wanted to be thorough in case they send up red flags for anyone...

    I need help with a starting problem. I have an 05 Cadillac CTS having starting issues, I have replaced the alternator the starter and the battery still won't work everyone says it's a grounding problem. (Moderator edit. Sub.)

    Hey everyone, I decided this would be the best spot to get a few answers on an issue I've been having. I own a 2008 CTS, RWD, with the 3.6l LLT. A couple months ago it developed a horrible rumbling/knocking sound around the mid front of the engine. It was summer, so my AC was on just about all...

    Back in February my engine started skipping and shuttering and have reduced power when I would be driving up inclines around 1800-2000rpm. Shortly after, the check engine light began blinking. I took it to the shop and had the spark plugs, engine valve cover gaskets, and engine intake manifold...

    Hello to all CTS Owners, I wanted to share my experience with you regarding the engine swap I performed on my 2013 CTS from the 3.0 LFW to the 3.6 LFX. Despite the considerable effort, challenges, I ultimately achieved success. Before the swap, my car's acceleration from 0 to 100 km/h took...

    My 2014 CTS has 95,000 miles on it and I was just told the rear differential is completely done. I took it to a very reputable transmission shop due to a leak in the back and they gave the awful news. They told me Cadillac no longer makes these for my year? There are none available to be found...

    Cadillac 2009 CTS. The car has been working well, all the doors and windows and seats. One day I pulled up to a gas station and when I went to unlock the door with the key it wasn't working. The only door that was working properly was the passenger side. The driver-side panel window and seat...

    The 6l50 found in the 08 cts is said to be rated at 315hp but the lfx already makes 323 so it has to be more. Furthermore I've seen built 3.6s that do fine on the 6l50. So does anyone have an idea what it actually is able to handle. Reason I'm asking is it would make an ls swap way easier...

    My 2005 Cadillac CTS for a couple weeks has been messing up with many things. As of right now it's: -gas and temp gauge won't move, at E -steering wheel is stiff but movable -service theft system comes on the dash and symbol lights up -key won't come out of the ignition and this caused my old...

    I have an 08 AWD CTS and have got to thinking about upgrading the engine since I would like some more performance out of it. However it is getting up there in age and is burning oil, which got me thinking about swapping the engine for a better performance engine. The engine I had in mind was a...

    Hello, I have a 2010 CTS, and just recently noticed that the instrument gauge back lighting stays on when the car is off, the doors are closed, and the car is locked. I waited about 5 minutes and they just stay on. I had a problem with my door actuator not working with the key fob so I replaced...

Really weird and annoying. Please anyone able to help with what it could be? I have a video but won’t let me...
