1994 Cadillac Deville problems
The Cadillac DeVille is a model name used by Cadillac over eight generations, originally used to designate a trim level of the 1949 Cadillac Series 62 and later to designate a standalone model in the brand range. The last model marketed specifically as a DeVille was the 2005 full-size sedan, at the time, Cadillac's largest model.
For 2006, the Deville nameplate was retired, when the model line was carried forward (with minor revisions) as the Cadillac DTS, using a nomenclature adopted by the Cadillac STS and CTS.
Early history
The name "DeVille" is derived from the French de la ville or de ville meaning "of the town". In French coach building parlance, a coupé de ville, from the French couper (to cut) i.e. shorten or reduce, was a short four-wheeled closed carriage with an inside seat for two and an outside seat for the driver and this smaller vehicle was intended for use in the town or city (de ville). An (unshortened) limousine or (in the United States) town car has a division between the passenger and driver compartments and if the driver's seat is outside it may be called a sedanca de ville or town car.
The first Cadillac "Coupe de Ville" was shown during the 1949 Motorama. It was built on a Cadillac Sixty Special chassis and featured a dummy air-scoop, chrome trim around front wheel openings, and a one-piece windshield and rear glass. The interior was black and trimmed in gray leather, including the headliner, to match the roof color. It was equipped with a telephone in the glove compartment, a vanity case and a secretarial pad in the rear armrest, power windows and highly decorative chrome interior trim. The prototype "Coupe de Ville" was used by GM President Charles E. Wilson until 1957 when he presented it to his secretary. At some time during this period it acquired a dark Vicodec roof. The prototype "Coupe de Ville" was found and restored in the 2010s; it was in a private collection in London, Ontario, Canada as of 2017.
The Cadillac Series 62 Coupe de Ville was introduced late in the 1949 model year. Along with the Buick Roadmaster Riviera, and the Oldsmobile 98 Holiday, it was among the first pillarless hardtop coupes ever produced. At US$3,496 ($44,768 in 2023 dollars ) it was only a dollar less than the Series 62 convertible, and like the convertible, it came with power windows standard. It was luxuriously trimmed, with leather upholstery and chrome 'bows' in the headliner to simulate the ribs of a convertible top. In its first year the Series 62 Coupe de Ville only sold 2,150 units. But 1950 sales more than doubled to 4507, and in 1951 sales more than doubled again to 10,241 exceeding the sales for the Series 62 Club Coupe that year. Also, in 1951, Coupe de Ville chrome script appeared on the rear roof pillar for the first time, to further distinguish it from the Series 62 Club Coupe.
In 1956 the Series 62 Coupe de Ville was joined by the Series 62 Sedan de Ville, Cadillac's first standard production 4-door hardtop. Similarly to the Coupe de Ville, it was also more expensive and more luxuriously trimmed than the standard 4-door Series 62. With 41,732 sold, it also easily outsold the Series 62 sedan in its very first year. Given their sales success, it was only natural that the Coupe de Ville and Sedan de Ville were moved to their own separate series in 1959, the Series 6300, being joined by a DeVille convertible in 1964.

I bought this car used from a local dealer. It's such an amazing vehicle! It's incredibly powerful and comfortable, and it drives like a sports car, hugging curves like a Porsche or BMW. Plus, it has trunk space that could easily hold the contents of a FedEx delivery van. And the interior is so spacious, it's like staying in a luxury hotel room! I'm really happy with my purchase.

Hi there! I have two 1994 Cadillac Deville's - a bright purple one and a recently purchased silver one. I absolutely love these cars! The purple one has 200,000 miles on it and the silver one has 125,000. The ride and room are just fantastic. I have had to replace the water pump on both a couple of times, but other than that, everything else works well. Do you have any experience with these cars?
-
I love this car! It has always started and was a great road car for commuting. We even used it as a family car and it literally saved my life one snowy night on the Central Artery in Boston. The trooper told me that a smaller car in a similar accident resulted in a fatality, but the Cadillac Deville never budged when muscled by a 10 wheeler truck. With 160,000 miles and headed for 200,000, this car has been a reliable companion.

Got caddy? Now you know what you're missing - style, class, comfort, and more!

It's great to hear that you're getting such good gas mileage on the highway! Driving at a slower speed of 55 mph can really make a difference, and it's impressive that you're getting close to 28 mpg. Even at higher speeds of 70-75 mph, you're still getting a respectable 22 mpg. In the city, you're averaging around 16-17 mpg, which is pretty good for a larger car like a Cadillac.

Are you having problems with your 1994 Cadillac Deville?
Jeramy Reinger 2024-09-26
I purchased the vehicle with 34,000 miles on it. Although the vehicle looked perfect, it had a poor heating system during the cold months and required over $500 to fix the gasket. Unfortunately, it started leaking in another place. While I had high expectations for Cadillac, I was disappointed that they did not take measures to prevent these issues. As a result, I have lost trust in the brand and will not be purchasing another Cadillac. The cost of maintenance is simply too high and I cannot risk driving an unreliable vehicle on the road.
Layne Marvin 2024-02-27
I have experienced multiple electrical issues and frequent service codes appearing on my computer. Despite the complexity of the diagnostics, I am confident in my ability to identify and resolve these issues efficiently.
Tanner Cummings 2024-02-16
Hi there! I wanted to share my experience with my car. I've had to do some maintenance work on it, like replacing the pull-down trunk module, re-hanging the rear view mirror a few times, and getting some tune-ups at 65,000 and 108,000 miles. I've also had to replace the alternator and repair the radiator (which needs fixing again), and the side molding has fallen off. The transmission vibrates between 43 and 48 MPH, and it burns oil. Additionally, the 'service ride system' warning light always comes on, but the dealer says there's no problem. I've had similar issues with my 1989 De Ville. Overall, it's been a bit of a hassle, but I still enjoy driving it. Let me know if you have any questions!
