: Northstar reliability...

So at work today a guy came in for a new blinker relay for a '99 DeVille.... So I go out to the car to look for the relay (never found it.... not under the dash where GM had them for decades) but upon walking into the parking lot... I noticed alot of stickers on the DeVille... and a thing on the roof....

It was a taxi! I was surprised, as I really never seen a DeVille taxi. It was white with black leather, in really nice shape... so I open the door and look for the relay...

they key was in the on position, as he was showing me the problem with the blinker....

I coudln't help but notice the 247,xxx miles on the car! I confirmed that was in fact true milage, I asked if it was the origanal engine and tranny and he said yes... its his own personal car that he uses as a taxi.

247k and it was still running great.... I was really happy to see that.... but these things will definitly last that long if given the chance, I just still find that really interesting.

Blinker didn't get fixed, I didn't know if it used the electronic or mechanical type blinker (computer listed both) and I didn't know where the damn thing even went. I did tell the guy aobut the site though and to give it a shot...

still, 247k, '99 DeVille, origanal engine and trans... and still runs great.... makes me wonder just how many are running around with 250k+ that are troublefree....

Great thread. Before I bought my car back in Nov 2004, all that I ever heard about the N*, was stories like you posted. I never heard of headgasket failures and the like. That right there was good enough for me. Now if the N* was truly a piece of crap, as some on this board will have you believe, I am sure that I would have heard about it, before Nov 2004. Just like any engine, there will always be some bad ones. There will also be some great ones, that get severely neglected, that turn into bad ones. Then there will be ones that you cannot kill, no matter what you do to them. The N* is a great engine. it has been around for at least 15 years. I love mine, and have plans of owning more in the future.

It's all about the maintenace.

Just remember, people don't come here just to say how great their engine is... they come here when there is a problem.

My Factory Service Manual says that there is a "Commercial" version of the Deville.

Well, commercial chassis.... thats what they made herse and limos from.

This is a regular '99 base DeVille, it was his personal vehicle, that was a taxi, all the graphics and the taxi sign on top etc...

Ooops...I means to say "Commercial Series". Different than "Commercial Chassis". My FSM has exceptions all over it for the CZ (Commercial Series) Devilles.

Anyways, doesn't matter.

Your STS is just a baby. My Deville has 298,000 miles on it.

Hasn't everybody here agreed 1,000 times that the long troublefree life of a Northstar depends on regular coolant changes (w/tablets)? :highfive:

The regular flasher is for the hazard lights. The electronic flasher is for the turn signals. They ARE under the dashboard, and somewhat hard to get to. The hazard flasher is easier. The signal flasher clips to the inside of the panel. I zip tied mine instead to a bundle of cables, quieting it significantly.

I live in upstate NY and I know in the city, New York City that is, there are thousands and thousands of DeVille taxis. It's really all they use around the airports and stuff. They're big, comfortable and reliable.

I think after 2000 most of the leaking problems had been resolved and at that point there were only a few faults. The lower valve body in the Trans sometimes goes bad and the TCC solenoid goes bad.

Other than that, the recent N* and trans have proven to be very very reliable and almost maintenance free, which is what the N* campaign was originally about. Low / No maintenance with reliability.

It's the same thing. It's just wording.

Is that the secret? I saw that in the book. What is considered regular and what do the tablets do?. I think the manual recomend every 100k

I am glad everyone is so happy with their Northstar engine. I just found out that my 2000 DeVille, 8 weeks out of the six year/100K warranty, with only 86,000 miles, has a blown headgasket and a transmission failure. All maintenance had been done by the dealer.

The unanimous advice from Cadillac customer service, the dealer we took the car to when it failed, and an independent mechanic, was that the car was not worth fixing.

No one can tell me that the dealer who serviced the car its entire life didn't know it was on its way out. It had an unexplained antifreeze loss for months, and chronic rough idle long prior to expiration of the warranty. They just waited it out.

Dealer integrity issues aside. Cadillac's solution is to give us a credit for $4,000 to buy a new car from them.

Call me bitter, but should my replacement car have a Northstar? Fool me once, shame on you...

If you have documents and can prove that the car was in for a problem while it was still under warranty, it should still be covered. I'd press the issue. The squeeky wheel gets the grease.

See my post on how many miles on your N*
Also heard of some Auroras with over 300K
