1999 Cadillac DeVille Owner Comments

I am very pissed about this car. Previously I had a Mercury Grand Marquis. I loved that car but I totaled it in a snow storm. Insurance gave me $2800 for a new car. I bought a Cadillac Deville, without doing much research (I am young and stupid I know, but regardless still pissed off).

Two days after buying it (this is around December) I get into an accident and rear-end someone. Insurance gives me another $2800 dollars and totals out my car. We buy the car back. We wait to get it repaired because we wait for our money to arrive. My car begins having coolant problems. We take my car to a mechanic he tells us its a water pump problem. It takes the f*cker TWO weeks to even begin working on my car. Another week to fix it.

He calls tells us to come pick up the car. I get the car. Hes not there left the keys on the seat. So I take my car go home. I call him. I have not heard back since and I started calling around March. Right after he repairs the water pump I take my car to a family friend and for 2200 dollars he repairs my bumper. I get my car back from him and the coolant issue starts again. Because we had not heard back from the first mechanic we take it to someone else. He tells us that what the real problem all along was a broken water pump AND the gasket heads were coming loose.

Because the first mechanic told us nothing, we spent insurance money fixing up a broken car and I continued to drive my car making things worse because i was in desperate need of a car. Overall had I had known that this model of car had such a huge issue I would have never bought it. I am very pissed.

DeVille LX 4.7L V8

December 2011 purchased vehicle used didnt know nothing about it until a few days later i noticed it was loosing antifreeze and oil. Using 1 gal a week of antifreeze and some oil. Took it too mechanic and he didn't want to mess with it and recommended taking it to the cadillac dealer. they really didnt' want to look at it they stated they knew what the problem was without looking at it. They told me that this make and year is real bad for having this problem after they reach 100000 miles. They said that it wasn't worth fixing because the repair cost more then what the car is worth.I think that its unfair that if this is so common then this should be considered a recall or some kind of defect. They should have to replace or fix problem. Now we have a nice car that is costing us lots of money just to drive. Most of the time I am forced to use a different vehicle.

DeVille Northstar

  • Automatic transmission
  • 88,000 miles

I have been a faithful Cadillac owner, for nearly 20yrs, After buying a couple of use Cadillac, on Sept/1999, my wife and I was finally able to now afford a new Cadillac. We purchased a Brand New 1999 Hunter Green Cadillac Deville, off the show room floor, with a $55,000 price tag. After financing the veh., the monthly notes were $770.00, for 72 months. plus $7000.00, cash down payment. The reason we made such a huge investment, was because of the quality service provided, any complaints were quickly addressed, but the main reason was because of the highly advertisement of the "Northstar Engine", no major maintenance until 100,000 miles, only Required Maintenance, and if the veh. runs hot, you were still able to drive several miles to safety.

DeVille LX

  • 65,000 miles

We had not owned the car one year and it started using more and more antifreeze. Mechanics could never find the leak so we had the water pump replaced, then a thermostat replaced. It became so bad until it finally dumped it all within a 6 mile trip. I barely made it home with my daughter at night, and when I did, it just smoked to beat the band. The #7 cylinder had a crack in it that had been splitting open larger and larger. What really hacks me off, is that the dealer who sold us this vehicle, knew the car had a coolant problem when the older gentleman traded it in. We found this out after the fact. My husband contacted this person and low and behold knows this gentleman. If we had the money, we would have hired an attorney and taken that dealer to the cleaners. The older gentleman told my husband that they (the dearler) smelled antifreeze too when they test drove it. The previous owner also had a new water pump installed, and finally got tired of putting antifreeze in it. This dealer is not a Cadillac dealer either. This family deals in all makes of cars. We begged Cadillac to help us out, being that this is the second Cadillac we have owned and all we got from them was free oil changes for a year that is more hassle to use than it's worth. At any rate, we owed too much to even dump the car, so had to put out $4,000 when it was all said and done. OK..... is there anyone out there that has had the same thing happen to them?? I have heard that this year of Northstar engines is notorious for the cracked cylinders.

Thank you so much for hearing my complaint. It's just that a company of this magnitude should stand behind their vehicles or recall them if there is a defect.
