[@bbsal4031]

I'm with you, I am always looking at the DTS. I would be willing to pay good money to have everything fixed on it if need be just so I could drive something like this. And we have a good mechanic one that we trust.

[@chemwrite]

I owned an '08 Performance DTS that I bought used, and here were my issues: One of the rear brake calipers seized and cause a problem that made the brakes shudder whenever the brakes were applied. It took a lot of looking until finally an independent shop correctly diagnosed the problem and fixed it. It was not costly, but it was miserable before it was corrected. The Magnetic Ride rear shocks needed to be replaced (they are sold as a pair) and they were really costly. My thermostat stuck and caused a number of problems and like the brakes, it took forever to get it diagnosed and corrected. The engine required a major rebuild that was covered under warranty, but it was caused by stretched timing chains. This was a wonderful car, but it nickle-and-dimed me to death. Lovely ride, quiet and just a joy to own...but it took some time to sort out.

I have a 2008 DTS. Bought it at 138k miles with the entire service history in the glove box back to nov of 2008. Replacing the power steering and plugging a tire is about all I’ve needed done to it so far in the last 4k miles. Next week is the oil change

I have a 2010 DTS with only 160,000 miles on it. I have the oil leak and the transmission cooler line problems just like what you said. I really liked the car and it runs well. Have a feeling it’s probably gonna cost a lot to get all of that fixed.

[@Michiganrox21]

I just got a great deal on a 2010 DTS. It’s been garaged and maintained properly only has 70k miles. Seeing this video kind of made me second guess my purchase but this car is simply amazing. If anyone has any tips for making it last for a long time please let me know.

[@jimsmith8797]

Check your oil and coolant every time you fill up. Check tranny fluid regularly as well.

[@bradleynelson5915]

To be honest, the best way is keep it low mileage, only use it for special occasions like I do mine. I use an old Impala daily .Replacement parts are alot cheaper on my Impala.

First Generation DTS would be 2000-2005. 2006-2011 would be Second Generation, or Last Generation since they were sadly discontinued afterwards.

[@dennisglodoski6365]

Yeah unfortunately the North Star has a bad reputation, but if you keep up with your coolant flushes every 2years you can definitely help avoid water pump and head gasket issues otherwise it’s a damn good engine in my opinion because by the 03 to ‘10 engine design GM changed the head bolts into a longer and coarser thread pitch design to help with the head gasket issue due to aluminum stress from heat expansion.

worst-case scenario try to bypass it with a new switch you can control-but if its a fuse that keeps blowing, check all your wires to ensure there is no opening or damage wires. if you are putting in a new motor and new switch there have to be almost ZERO issues, if you have a dead motor with few hours of new usage....maybe you may have an open wire somewhere for sure, carefully inspect your door hinge areas, your interior panel (deep Door Inspection)... try to do a test on the motor itself to see if it actually works, then the switch and work back to your harness then lastly your fuses.

How many cars has he owned?!

[@francisgillan504]

Owned a 2007 DTS that I bought special ordered new and owned for 11 years. I put 124,000 miles on it. I special ordered my car to have the adaptive cruise control option, which is rare for this model. My engine started leaking oil after 5 years. The only way to really fix it was to spend $2k+ to remove the engine to replace the leaking seals. I had my mechanic tighten up everything on the engine that he could without removing the engine. I placed mats under the engine to catch the oil and added a quart of oil about every other month. I did this for years. Luckily the car had an accurate low oil indicator sensor that allowed me to monitor this. I also had the problem with rear door latches. The most annoying problem I had with this car was a vibration in the front end at 60-70 MPH. I rebalanced the tires, rotated tires, replaced tires and had the front end aligned and inspected multiple times. After several years I replaced the front wheel bearings and that finally solved the problem. When I went to sell or trade in my car I found that it had virtually no resale value primarily due to the Northstar. GM fixed the head gasket failures in the Northstar by 2006 but the Northstar still leaked oil after 2005. I also owned a 2006 Buick Lucerne with the optional Northstar, which I owned for 10+ years and put 100k miles on it. It also leaked oil. Neither engine failed while I owned them but I will never get the oil stains up from the floor of my garage.

I found one super clean only 70000 Km on it 7500 Canadian maybe I can get it for 6 v8 4.6 litter grey colour just looks sick and I’m very into old cars I just wonder how is the comfort in this anyways long story short I was looking at this car on Kijiji and loved it maybe I can get it for 6k with only 70000 Km on it I wonder how is reliability and how is comfort from 1 to 10 this car I’m not very familiar with American cars but I do love them and I’m starting to get into American cars I’m from Iraq so in Canada I wanna support North American products and I want them to be great again they are good now days changed a lot but anyways the more people support them the better cars they can make and I was always into American cars is just reliability however after 2015 American cars became really nice and good and advanced so long story short my heart still goes into old cars some cars were reliable some weren’t now most are reliable but before some were good some weren’t and I wonder how this car is sorry for long message lol I like to go into details hehe

Don't forget about the Cadillac converter

[@zarstar1576]

What about converter....I had code...but put cats clean in it.

[@davyd4355]

It’s actually called a catalytic converter

my 06 Dts is acting funny almost like it's stuck in valet mode I can't control my headlights,blinkers don't work and trunk wont open at all anyone have any suggestions ??

[@mikehall737]

Im swapping out my Northstar with a ls4 5.3 it's cheaper more durable and I can work on it before drop.

[@modelotime3608]

If you can make it fit. My caddy doesn't even fit a 5.0 coyote properly

[@tstahler5420]

We owned a 2002 DTS, it was most definitely a 1st gen car.

[@djizzal20]

I had the oil leak problems from the oil pan gasket and timing chain gasket. Cost me $2800 to fix 😣 Cadillacs definitely not for the weak. If u don't have money to fix them or not a mechanic u maybe want to stay away 😹

[@rickrodriguez5875]

What year?

[@robertthomas5906]

$2800 sounds like a normal service call for a BMW or Audi.

[@livdouglas3410]

I have a 2008 red DTS... Iv has lot problems... Paid lot money on several things to get fix Now check engine light on again Hesitate to start... then it finally catches and start.. my battery is almost new. Wondering what could it be???

How did you not include the engine killing head gasket for the northstar? Only way to fix is to remove the engine from the car. Terrible engine design. GM got this one horribly wrong, but they learned and stopped making it.

[@DMoney505]

Head gasket issues weren’t as common in these years. It was a head stud issue, The older generation had the issues. Not so much for the new gens, otherwise an amazing engine!

[@joerubbo583]

@@DMoney505 An amazing engine that they stopped making on 2011 and haven't made a similar one since

[@seanpeacejohn889]

I'm not saying you're wrong but what would you have to say to the people who've exceeded 200,000+ miles on their DTS.... Maybe the design is bad and not ideal for changing out parts but like but I believe the motor it self run strong.

[@FenrisTheMannis]

He didn't mention it because DTS were never more prone to head gasket failure than any others car with aluminum blocs. GM solved the head gasket problem during the 2nd half of 2004 by using longer, bigger head bolts with coarser thread (the same as the LS1, if I remember correctly).

[@TeeroyHammermill]

@Joe Rubbo: Just flush the coolant according to schedule and use the dexcool. The headgasket problem wont happen.

That's the very last generation of Deville Touring Sedan DTS. Definitely not the 1st.👍🏾

[@caddyguy5369]

They changed it from DeVille to DTS in 2006. 2006-2011 was indeed the first body style of the DTS model. It replaced the DeVille. It was also the last body style for that model. Yes, the previous DeVille's did have a DTS trim package, but the model was still DeVille. Pretty much the same car though for the most part. Some differences other than appearance.

[@TeeroyHammermill]

DTS means Deville Touring Sedan so this car is essentially a Deville

[@LeeBo318]

@@caddyguy5369 no they didn't, because my dad has the very first one that was released in 05, so what we have here is definitely the last gen.

[@k.c.marshall921]

2006-2011 is actually 2nd generation DTS.

[@alanholmes2366]

GM is horrible about having the failure modes always in a position where half the car has to be taken apart to repair the car. Oil leaks 75.00 in parts but 1000 or more in labor to fix 😳 Ridiculous. Might as well buy a BMW or a Mercedes and have a top level luxury car. At least then the high cost of repairs would be worth it to have a real premium luxury car. I’m a previous owner of 3 Cadillac’s never again!!!

[@toothrestorer6588]

Mercedes and BMWs have many issues when they get to a similar age and their values fall similar amounts due to the cost and likelihood of repairs
