1998 Cadillac DeVille Problems
The engine may develop oil leaks from the lower crankcase portion of the engine block. Our technicians tell us that the engine must be removed from the vehicle to properly repair this oil leak.
One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.
The crankshaft position sensor may fail causing the engine to stall intermittently, the Check Engine Light may or may not illuminate.
The trunk pull down switch may fail causing the trunk lid not to close completely. Our technicians tell us that the failed switch can be replaced without changing the complete pull down motor assembly.

1998 Cadillac DeVille Reviews
This is the car that you want if you take long trips, or if you like driving in the city at low speeds. This is by no means a sports car and should be driven by people who aren't erratic drivers.
Extreme comfort in this car. The buttons and controls are all easy to deal with.
It has some known issues that are basically universal to this engine...it is not terribly easy to work on because of limited space, but is much easier than your German luxury cars.
All in all, I love this car, and if you can find a good one, get it.
This is my 3rd cadilac. I bought it used in August and I knew it had a few issues to fix then. Nothing I couldn't fix later. The speedometer didn't work and the drivers window only goes down about 4 inches and the drivers side mirror will not adjust from the inside. But other than that, the car is as clean as a showroom car.. I drove it all over for a few months and wouldn't be afraid to drive anywhere in it. I just bought a GPS to tell me what speed I was going instead of fixing the speedometer right now. But last weekend I did have to put a altenater on it. But on a used car, you have to expect things like that once in awhile. No since to be upset yet. I had a 88 deville and loved it and never spent a dime on repairs before a semi ran into me from behind. Then I replaced it with a 91 Cadilac Eldorado and I would have drove the wheels off it had a tree not fell on top of it 6 years later. So I replaced it with a lemon of a van that I put money in left and right for 5 1/2 yrs and finally sold it this summer and bought this cadilac. Seems they were good to me. I don't care that we're supposed to buy cars with 40 mile per hour milege, I want what I'm familiar and comfortable with.
My 1998 Northstar (Sedan DeVille) gets 31MPG on the highway. I learned after I had the engine replaced, that it has been well established that the early Northstars were prone to develop warped heads and then the coolant leaks, the engine overheats, etc., and eventually the engine just fails. There is a Fix for this, (maybe $100 in parts, plus labor), which GM rigorously avoided until the later years (mid 2000's). Had they put these better bolts in the engines in the first place, there would have been no problem, and the cost would have been negligible. The head bolts are simply a half inch too short on the older Northstars, permitting the heads to flex and warp, particularly as the older gaskets became 'dry' or compressed. Any Cadillac Dealer will be able to tell you (from the VIN number) if you have the defective engine (they won't use the word 'defective'). There is a Head Bolt kit that is available, for retrofits. If I had a Northstar with low mileage, and it wasn't overheating or leaking or chewing up oil, I would pay to have the engine disassembled, remove the heads, replace the Gaskets, and put in the newer/longer head bolts. Then this engine would last forever, so long as you change the 8 quarts of oil every 3,500 miles. This fix is about $1K, but is cheaper than the $4-5K engine replacement.
Im 28years old and I love this car. I bought this car a year ago from someone that took great care of the car. only thing I have had to do is replace brakes but with 74,000 miles its to be expected. this is 2011 and almost 2012 and this is my favorite car i also own a 2007 ford expidition fully loaded good suv for the family and wife but after a few days of driving the caddy it makes driving that suv feel like a cheep piece of sh**. Only reason this car didnt get all stars on body,interior, & misc* and electrical and lights is because its 2012 and a lil outdated. will for sure keep this car till she dies.
I just bought my 1998 Cadillac Deville July 4, 2011. It was running great for a day and the check engine came on. Well, it over heated so I had it fixed and they said it was ok. The next day bright and early the check engine came on again and the mechanic is saying transmission issues which to fix is more than the car is worth! I regret buying this car so bad!! I should've known Cadi's were pieces of, well, I think most of you know! A total waste of money!!!!
