Cadillac CT6 Things You Should Know Before You Buy 

Having problems with back ventilation blinds not working! 2019 CT6

I have a 2016 base with the 3.6, awd and the 8l45 transmission. I picked it up off a lease with 59K on the odometer. It didn’t take long for me to notice the shudder and I had to do some homework before I knew what it was. There’s a class action lawsuit over the transmission and a few TSB’s - the last which is flushing and changing the fluid to the “correct type fluid” - all done on GM’s dime. I had mine serviced and got about 7,000 miles and felt the shudder beginning again so I brought it back. This time they swapped the torque converter and fluid again. I’m over 20K daily driving and that problem is a thing of the past. Fingers crossed it stays that way. Next: the air conditioning. Summer 2020 in July - I come out of work in Manhattan to zero functioning air conditioning. I drove through the Battery tunnel with the commuter busses in traffic. That sucked. Nothing got it to blow cold until I got to Staten Island at home and disconnected my ground on my battery. I did a “hard reset” - everything worked perfect immediately after. But the issue kept happening an I noticed that the temperature gauge on the dash was bottomed to the lowest temperature and the electric cooling fans were on full blast. Every time I did a reset it fixed it but it would happen again at least 3 times a week. All of the Cadillac forums had people saying they went to the dealership and had to get the air conditioning fixed. I wasn’t satisfied because with the reboot it still worked. So I did more homework. As it turns out - the 3.6 (LGX) is also installed in the same year(s) Camaros. The difference is most Cadillac owners probably don’t even open their hoods, nonetheless work on their cars. They bring the car to the dealership. Camaro owners do tend to “play with their cars” I’m a diehard hotrodder! I have big block toys, GM toys, Mopar toys and I like fixing things. So I went to a Camaro forum and there it was in print. The answers to the air conditioning problem. With the LGX 3.6 engine. The thermostat is the problem. If you start your vehicle and drive off and the engine doesn’t get up to temperature within a time threshold your BCM and ECM will think the engine is low on coolant and put the vehicle into a default limp mode. It shuts off the air conditioning and runs the fans. Now for more fun. The thermostat is in between bank 1 & 2 at the bottom of the V , under the intake manifold so it’s a costly repair not recommended for a novice. I have yet to take the time to do the job myself but for the meantime. I run the vehicle with the remote start twice before I go anywhere - EVERY-TIME. I’ve been doing so for almost 2 years and I never have a problem. Sorry for the long winded comment but I hope it helps someone…

No problem with my CT6 😎

I love my 2016 CT6. I have owned it since it had 6000 miles on it. That was way back in 2017. Only problem I have had is with the turbos and that was covered by the warranty. It now has 175,000 miles. Joe

So there's "nothing wrong with the CT6"..............but the AC doesn't work sometimes, the transmission whines, and there's a "preferred provider" scam that you'll have to pay a premium for. OK.

I have a 2017 ct6 only issue has been a fuel sensor. Smooth ride overall.

I had a 2016 Platinum edition and totally regret to have traded it in. That was a fine vehicle and I've owned many Cads, Lincolns. BMW, MB as well as most American model vehicles

Luv Cadillac)

I need a front headlight for a 2020 Cadillac ct6

I have a 2017 ct6 3.6l and the transmission also shifts alittle rough 1 - 2 gear but is smooth the rest. Does anyone have the same problem and could you recommend a fix?

I bought a brand new 2017 Cadillac CT6 when I 1st got it I had air conditioning trouble I took it back to the dealership and they Flash it and put new coolant in the system it was blow Cold and it blow hot.. that tells me why no cooling in the system so they done that AC works fine Had a probably with the transmission took in 3 dynastic with some different types of code flush the transmission took again late for transmission again. I only problem with these transmissions on a these new cars is that they are SEALED TRANSMISSION NEED TO BREATHE THEY ARE MOVING PARTS other than that I'm keeping my 2017 cadillac CT6 I love it... YOU'RE GOING TO HAVE PROBLEMS OUT OF ALL NEW CARS ...........

I have a 2020 CT6 V8. No AC issues yet. No transmission issues yet. My issues: Sunroof drain leaking / replacement.

I have rough shifts occasionally on my 2017 CT6 in lower gears. I hate to say it guy but the Genesis feels like better quality than the Cadillac.

I have a 2017 and I had the same problem with the transmission

I have found it necessary to put the AC on "recirculat" when the outside temp is above 100. My Toyota does this automatically but my 18 CT6 doesn't do it automatically and it is normally in "fresh air" unless you manually put it in recirculat. I am in TX and it has been over 100 for weeks.

nice vid, I had just traded my 2014 Cadillac xts luxury for a 2017 Cadillac CT6 premium luxury love the car hope I have luck and nice vid again brother much love from Chicago

Are you the Owner of the car? Or paying monthly? I believe if you out right own the vehicle, you, can have anyone work on the car as long as you trust them and agree to it. But if you don't then of course insurance will be picky on how to fix the vehicle.

I have a 2017 CT6 3.0 TT with 36,000 miles.... I have a delayed rough shift from 1st to 2nd gear for about 15mins and after that it smoothes out until I restart the car. The Dealer said 'I would have to deal with it" because GM knows about the problem but will not fix it unless my Transmission fails completely. It has the updated fluid and latest software update also......

I have a 2019 CT6. The only issue I have is that my super cruise stays engaged for maybe 7-10 seconds and disengages. Other than that. I am in love with my CT6. The dealership said it could be several things. But I would have to leave it with them for a few days. Just got to find the time to do that.

I have cadillac 18 cts , had noise from the transmission, took in to the dealer, they changed transmission fluid which solved that problem, no other issues only have over 9,000 miles, a very good car

Damn, those are HUGE problems. You are lucky you didn't have to drop thousands on that Transmission. That's GM for you.

Mine the thermostat housing went bad bringing on the engine light. At 62000 miles Will fix it but don’t know what else will come up

Nonsense I don't believe what he is saying about the body shop & the ct6

Cooling fan slow to turn off

I have a 2018 ct6 platinum edition and 1st and 2nd gear is a rough shift and i hate how the transmission sound when idiling

why is the driver on the wrong side of the driver's seat??

Bro. Do you have steering week on the other size like in the UK? 😅

Any reason to flip the video so it looks like you drive a right-hand steering car?

Thanks for your update - I have the 2018 CT6 - Traans- bumps 2 to 1 downshift common wuththis 8 speed trans - fixed under warranty and refilled with Mobil 1 HP trans fluid @ 30,000 - I will keep this car (now @ 35,000 miles and will buy an extended warranty! Thanks again for your help.

I bought the Cadillac 2018 with 15521 miles took it off the next day after bringing it back I have the brake system fail I haven't get it back over a month now what do you suggest

I have had three Cadillac CT6's. 2 2017's each of which never made it to 4000 miles before I got rid of them. Build quality, electrical glitches and the gawdawful 8 speed transmission contributed to the worse new car ownership ever. My 2019 is the identical car with a better 10 speed transmission, which shifts like a normal car. This is an entry level luxury car and cheaply built. In spite of all this, it's a nice looking sedan but loaded with issues that absolutely require bumper to bumper warranty protection.

Turn off selfie mode - everything is backwards

Is your car somehow right drive?

I’ve had the air conditioning issues seems like after a long trip 4/5hr drive something happens with AC I’ve taken it to dealership they say it’s all good

I liked and subscribed

HI...CADDILAC 😊 MAN ME TO. KEEP YOUR CAT6 CADDY. EVERYONE LOVES MY CADDY & THE RIDE. CT6 3.O TT IS FAST. 😊 ELECT CARS ARE NOT THE WAY TO GO. WISHING THE BEST. 😊

Those are my favorite year and model car

How much was it to fix the transmission?

I have a CT6 2018 Cadillac that top of my reservoir cracked a little 😢 what should I do?

My family gave my grandpa a XTS, and it has the same air conditioning problem, for 8 years, it just never stoped, I thought it was the problem that the car was produced in china so it would have these issue, but according to you, it seems like that’s also the case within states, anyway, even when it’s working, the air isn’t cool enough, and in where I’m from summer can be as hot as Miami, lucky that my grandpa is 70 years old and don’t really need that much cool air, but still the car itself is great, 8 years with very little issue compare to a bmw, and i am now considering to buy a used ct6 as my first car.

Great information! I am thinking of getting me a CT6. How is the car running now?

How to get the ac blowing air directly at you

A/C sensor

This was very informative, I may just get a genisis 🤷‍♂️ I want something to keep for years. Would you reccomend the 2019-2020 ct6 as a daily driver for long term use? Great content and information in your video im happy to have subscribed!

So Onstar does not help diagnose those issues?

👍🏾👍🏾👍🏾

Yes we had this problem with our 2010 Acura Tl. The problem with the AC only happens after an hour or more driving, short trips it works fine.The dealership couldn't find the problem so they changed the blend motor Actuator, after another 6 months the problem came back and they changed the blower motor. Then four months later I same problem I took it back, cuss them out to get it fixed and the finally found the evaporator coil freezing up and replaced it, no more issues now after one year, AC works great

They changed due may work oil in transmission fixed put air cond in auto it started up then cool

Ok

I own a 2017 ct6 3.0tt. I've had shuttering issues. I took it to the dealer. They flushed the transmission fluid and put new fluid in. It still shifts a little hard in 1st gear when you first start up but rides find after that. Thanks for the info. I'm glad I still have warranty. I once own a 2014 cts 2.0t and had no issues at all

As much as I like the CT6, I would NEVER buy a Cadillac thst isn't on manufacturer's warranty.
