Faults:

I have had to replace the rack/pinion assembly.

I have replaced the coolant reservoir, all 4 wheel hub assemblies, and both tie rod ends and all front bushings.

I also replaced a small rubber gasket on the intake.

To me, all were considered normal wear and tear, taking into account the mileage.

There is minor leather wear on the front 2 seats, but it's expected, and that's about it.

General Comments:

The DeVille is a car you should expect lesser than average gas mileage, (it's big!). It's Cadillac so parts are going to be expensive. When it comes down to it, it's a car you must expect to be a bit spendy, but in turn, you get a beautiful car with curves of yesteryear.

Cadillacs have been offering the smoothest "floating" rides for years, and the DeVille is no exception. Sure there is pricey repairs and not so great gas mileage, however you're treated to comfort, quality steel structure, smooth Northstar engine and more space than you can fill. I still pull 21mpg highway @ 117,850 on the odo with stock plugs and sensors... not bad for a big body.

Faults:

07/2006 shimmy in front end at 49109 miles, dealership blaming tires.

Steering and suspension issues at 51484 miles still having vibration issue.

Rack and pinion replaced. on going issues had to have transmission and left front tie rod repaired at 71726 miles. by then out of warranty and Cadillac's response "will give 2100 toward purchase of new car".

Car using a lot of oil since new and leather seats worn worse then replacment car at age of 13 years.

General Comments:

Nice looking car (package)

But quality no longer with package.

Faults:

Bad catalytic converter which makes a horrible growling noise sporadically.

Passenger side mirror only works when it wants to.

8 inch rear speaker blew recently which sounds terrible... costly to replace $150-200 for one speaker.

Bad emission parts had to replace air pump / $400 dollars it was estimated at $650 - 700 at dealer.

Bad lower passenger side ball joint which made the car vibrate, but with a few select tires and an alignment the car rides smooth.

Radio buttons wear with normal use.

Noisy pistons during warm up in cold weather.

Swallows oil crazily 1 quart every 1000-1500 miles.

General Comments:

Even after all the money I've putout to fix these problem I still recommend this car! very solid design being digital dash which includes all the bells and whistles.

The most comfortable car I've ever driven being I am 6'6 290. recommend getting an extended warranty through a secondary warranty company to cover small repairs others describe such as window regulators, mirrors, tie rods, ect. and I'm still not yet confident with the northstar engines how do others fell about this especially since it eats so much oil? for a $40,000+ car the resale value at this point is around $9000-14000 for the money you can't pass this car up even if you put 2000-3000 in to it it's a beautiful smooth comfortable diamond in the rough.

Faults:

Torque converter solenoid went out at 70,000 miles.

Window regulators broke at various times.

Heater fan quit at 80,000.

Rear speakers blew at 85,000.

Had trouble with brake rotors warping.

General Comments:

This is the second Deville that I have owned, and I would never own another one. I thought that when I bought GM's top of the line car, that I would be getting a car that was well built and reliable. It was a very comfortable car, but the quality was not nearly what I was expecting, and the repair costs were outrageous in my opinion.

I drive about 40,000 miles a year, and pay close attention to all the operating costs of the cars that I owned, and the Deville was by far the most expensive to operate that I have ever owned. I decided that the nice ride was not nice enough to justify the excessive cost. For example, the repair bill on the heater fan was close to $500. I remember when you could buy one of these for $20 and install it yourself in 15 minutes. Maybe I am just getting too old!
