2004 Cadillac CTS Problems
The passenger seat sensor may fail causing the SRS (airbag) light to illuminate. This problem has turned into a recall on some vehicles. Please contact you local dealer to see if your particular car is included. For more information on this recall, please click here»
The steering wheel position sensor may fail, resulting in the service stability message being displayed.
The front and rear light bulbs are prone to premature failure. Our technicians tell us that the front bulbs can be very difficult to replace.
The rear axle pinion seal may leak causing fluid loss and possible internal rear end damage. Replacing the faulty seal will commonly correct this concern. Some 2005-2007 models have been recalled for this issue.

RepairPal Expert Overview:
An interaction between the sensing and diagnostic module and the vehicle's electrical system may cause the drivers' frontal air bag and/or the roof-mounted side impact air bag to deploy when the key is turned to the "on" position. A person may receive minor injuries if the air bag deploys without warning. Dealers will replace the sensing and diagnostic module free of charge. The recall began May 20, 2005. The GM recall number is 05004.
RepairPal Expert Overview:
The front anchor tabs for the front bucket seats may not be engaged in the floor pan reinforcement slots and could potentially pivot rearward in a crash. This could increase the risk of injury to the seat occupant and a rear seat occupant. Dealers will ensure that both front anchor tabs are fully seated in the floor pan reinforcement slots. The recall began September 19, 2003. The GM recall number is 03050.

RepairPal Expert Overview:
The washer for the control arm ball stud may have been made of the wrong material, and may fracture and fall out, or become loose. The control arm may separate from the steering knuckle due to disengagement of the tapered stud, causing the vehicle to drop at that corner. In extreme situations, the wheel may separate completely from the vehicle. Either condition would impair handling and increase the chances of a crash. Dealers will inspect the torque on the ball stud joints on all front and rear lower control arms. If the torque is not to specification, the ball stud, knuckle, and nut will be replaced. If the torque is to specification, the dealers will replace only the ball stud nut and washer. The recall began August 24, 2004. The GM recall number is 04043.

2004 Cadillac CTS Reviews
What is up with the trunk lid, ity is so heavy the wind blew it shut on my head today and almost knocked me out? This should be recalled!
I had absolutely no problems out of this car until I hit the one year mark of having it. Now I am almost through the second year and have had nothing but problems out of it!!! Computer, sensors, timing chain, exhaust, u name it there has been a problem. Within the last 6 months I have put more than $3000 dollars in repairs for this thing and it is now at the dealer AGAIN!!!!! Cost to repair this time 1476!!!! Do not recommend this car to anyone if they do not have the cash to fix it unexpectedly!!!!
I have a CTS 2004, starting to hear fluids inside the rear door.
What could it be?
Delightfull car to drive and a completley relaxing and enjoyable experience however reliability is a little concern due to wierd electrical quirks that require it to be taken to a Cadillac dealership where they will almost definatley stiff you. If you can afford a few extra grand a year in maintenance without ripping your hair out they its awsome. As long as you are prepared for the extra maintenance expense.
We have had numerous problems with this car. From the power control module to the crank shaft sensor to the traction control. I would say run as fast as you can from this car.
