I've been running a '05 STS with 4.6L North Star and MRC since Aug. '07. I have done all of the work except a major head gasket repair.... meaning I know the car extremely well over these 14 years. It is now at 172K miles. 1) I have never had an oil leak and my car has been on the road for 16.5 years now. 2) I have never lost my clock on my radio. You can buy a Nav update disc pretty cheap to update your maps if that is the issue. I had my NAV replaced under GMPP at year 5 due to losing screen calibration. The replacement NAV system has the same problem the past 3 years. Calibration comes back on a restart usually. Things that I would mention to potential buyers.... A) the 4.6L NS with MRC is an absolute blast to drive. Sorry that you got bypassed on MRC. Note, under that electrical tape on the connector you will likely find a $5 resistor to fool the BCM (otherwise you would have suspension errors). If you plan to keep your STS remove the resistor and go back to MRC struts. There is a reason that this technology was ported to the Corvette and even Ferrari. B) matched front and rear staggered tires are getting hard to find C) I run on 87 octane 98% of the time D) MRC struts and springs cost me $2,200 just for Delco parts E) the transmission is sealed and very, very difficult to access the fill port F) if you have fun with the 4.6L you WILL wear out your differential carrier bushing and need to replace it to get rid of the torque thump. It is a $23 part but 4 hours of labor.

Thanks for your videos. I got an 05 STS earlier this year. I love it. Your Caddi run downs have been very helpful, sir.

Got an 07 v6 STS, had timely oil changes and routine maintenance. She still runs beautifully and is quiet as a hybrid. Timing chain problems were/are caused by poor oil quality and long time between oil changes. And all aluminum blocks burn oil. This ties into the poor oil change routine.

My Dad gave me a 2005 sts garage kept with 20k miles! Hope none of this happens to it like this! Checked for recalls

I used to own a 2005( bought in 2009) V8 AWD with the 18" staggered wheel set up, HUD and adaptive cruise. The issues I had were with the transaxle( replaced with a rebuilt unit under warranty). I also a issue where the display on the Nav was very dim on cold days for about the first 20 minutes of driving. There was also a cover for the power driver seat controls that came off and the lamination peeled off the front door handles I sold that car in 2015. I think it had about 80K miles at the time

Thank you. l just got a 2005 Deville and it helps to hear the things to watch out for

Dealing with that headlight issue, Seal it with some clear silicone. Believe me it will get the job done!

My 09 sts had two timing chains in four years. They had a manufacturer warranty up to 90,000 miles

Another good video man, well done. One head's up though, the '08-'10 Northstars don't require premium fuel. It's recommended but not required.

Bro this is exactly wtf i was looking thank you so much man shit just got a 05 v8 a few days ago

I wanna put a aftermarket stereo on ig but one I got told these cars are speical and needed to buy a 100 dollar piece I have the 2005 Cadillac STS v8

Good on ya bro. Appreciate the video. My last caddy was a dts. First this I did besides a fresh tank of Premium was Bull Horns strapped to the front. Gosh darn did she fudge up with the head gasket & torque converter. Paid for it loved her. But at the end of the day... I'd do it again cuz she was gorgeous. Got it it in Cashmere gold. Got mercedes E320 in champagne gold 2 day before. It's like when ya get a dog. It needs a lil buddy right! Anywho, cheers

What year is yours? Because your front end is from the 2008-2011 but the rear and interior are from the 2005-2007. I had a 2007. I loved my STS best car I ever had. I got it when I was 24. Traded it in for a newer Malibu tho. Way toooooo many issues.

Hey Dan great video! Good discussion about the STS & Northstar, etc. I’m shopping for an STS myself.

had a v6 sts 92k miles bought for 3k shit was amazing

Got an 09. Tuned. I beat the shit out of mine. V8 naturally aspirated, safest way to burn gas.

I bought an 05 cadillac sts and the timing chain went out after 6,000 miles. So yes he is correct

What you guys think about 2009 sts northstar awd 95k miles for 5k . Fully loaded

great looking car

I just bought a 2009 sts4. V8 all wheel drive with 120,000 miles. Got it for $1300. Paint is flawless and interior is super clean. What are your thoughts? Should i sell it or keep?

I own a 07 , spot on truth.

I have a 03 Seville STS . I live driving it.

I wouldn’t recommend the 3.6 V6 for any General Motors product. Pretty much any first gen High Feature V6 is known for timing chain failures and oil consumption.

I love theSTS ,so fast! Lol

I was about to buy a 2007 v6 sts 70000miles what u think about it?

Thank you for the video.

had to drill a hole in the brake light assembly top and bottom to slide the motorcyle led strip in there, 15bucks amazon, had to get the old school crew clamp because all pressure fitting conflict with after market items. thermostat i had to grab my baby hands out the tool box to reach, dont forget to pump 2 gallons of transmission until it pours out. loll dont by for grand pa noted 09 sts

I had 2002 Seville sts v8 ride was so reliable! Until I put it in the ditch and knocked my rack and pinion off but wasn’t to expensive only a 300$ fix

NorthStar Performance has all the mods you need bro!

Thank you!!

What about hard to turn power steering ? Like turning the wheeling at start up pulling out of drive or parking space have to wrestle with it but once going is fine.

You’re lucky you got the 2nd gen and v8. I’m looking for one but I want the sts4. Would you know which v8 is better? The 1st gen or 2nd?

Good information. Thanks.

I might get a sts v

I had timing issues!!!

If you love electrical problems a sts is a perfect one for you 😂

I bought an 08 STS in 2009. Overall it was not an Expensive Car to own. Warranty replaced the Steering Wheel, Heater Core, Water Pump, Timing Chains. My Repairs were 2 Ignition Coils, Motor Mount, Differential Mount Bushing, Rear Wheel Bearing, Gear Shift Control. Changing the Headlamp Bulbs is a real Bitch, I really would like to meet the Bastards that designed this Car Rode like it had no Springs, My Kidneys still hurt, and it had the Soft Suspension. Some Bitch went thru a Red Light, while I was turning Left. Car was drivable with a Bent Headlamp, and busted Bumper Cover. I waited 2 yrs before filing the Insurance Claim, and the Car was written off, about a Month ago. I kept it, sold it to a Friend and he is going to repair it and get inspected.

When he said get a Northstar I left the video feed .

thanks for the info. I have a 2011 cadillac sts. i think i have a timing chain problem because every 600 or so miles i get a check engine light for code p0008

how is the leg room space in the back seats

The cover doesn't have to be there???

Aye bro I’m thinking about gettin a 2005 StS with 3.6L V6 and it only has 90,000 miles , should I get it ?

You know no we don’t that’s why we’re watching it you know

Steering wheel *

Bro that kato!

Haha the 2005 to 2011 LH2 Northstar V8 didn't have these problems. The 3.6 V6 were junk with timing chain issues.

And use Seaform every 2 months run good

Northstar no mager problem

But im goin STS V

YA Know YA KNOW 🛑

Do a racing video or a burnout one 🔥

You know if you're going to do a video rehearse your stuff first. I have this car and believe me I know what's wrong with her. Just stopping by to check out what you had to say and you took too long to bring it out of your mouth you must know before you get behind a camera what you're going to say

Ta Know Uum NO

Those Northstar V8... are notorious for the head bolts pull themselves out of the block!!.... then...they sell you the same bolts for replacement!!.... same problem!
