2010 Cadillac DTS Luxury - Answered Questions & Fixed issues

it has to go into the radiator low somewhere, look for the start of it there...the other end may be > the water pump outlet. Usually...unless there is something freaky about the particular one, these rad hoses are clamped either end with either a stiff spring clip clamp, which needs pliers ...or a gear clamp, which needs screwdriver.Have something in place to drain radiator contents into.

If the Stabilitrak Yaw sensor box gets full of water you will get the Service Stabilitrak message.
The 2006-2011 Cadillac DTS and Buick Lucerne have a manufacturing defect of a major water leak problem at the bottom of the driver's side A pillar just below the windshield, accessible after the air inlet grille panel under the wiper blades is removed. The GM service manual bulletin #PI0356A (June 8, 2011) vaguely outlines how to seal off this opening, see attached photo taken from this bulletin. After sealing the obvious unsealed seams, I had to use fire-block insulating foam to close off the large 1 inch remaining upper opening.
The Cadillac DTS has another water leak path in the left front hinge pillar area under the wheelhouse liner noted in the same service bulletin.
In our Lucerne CXS, water actually flooded the Stabilitrak Yaw sensor box which is under the carpet under the driver's seat, resulting in the service Stabilitrak message . It's a major chore to remove the seats, trim and center console just to get the carpets out to dry. The carpets are difficult to dry because they have 1 inch of foam attached which holds a lot of water.
After removing the carpets and sealing the obvious seams, water still poured in when tested with a water hose and it was then I discovered that the water was getting in through the large upper opening which I used fire-block foam to seal. It's best to water test before you put everything back together.
You can quickly check if you have a water leak problem in your vehicle by popping up the rear seat bottom, removing the carpet clip and lifting the carpet on the driver's side rear passenger seat. Ours had about a 1/2 inch of standing water plus a lot more held in the carpet's foam rubber.
I was able to reuse the flooded Stabilitrak Yaw sensor by opening the box, shaking out the water, rinsing the insides with isopropyl alcohol and drying with a hair dryer. The service message went out and the Stabilitrak works in my attempts to slide around on gravel.
I'm surprised that GM didn't have a recall as I consider Stabilitak to be safety equipment.

Try to check for codes using a code reader. It could be the temperature sensor is going out.

That is usually a problem with the overdrive lockup solenoid inside the transmission.

It sounds like you have a failed transmission.

Not sure what you're saying but if you mean the sunroof slides closed but the rear doesn't come down and seat fully, the I'd start by looking to make sure nothing is in the way of it fully closing, also when was the last time you greased the slides on the sun roof?

Probably the receiver for the key chip. It has to go back on. But it doesn't have to be programmed. Replace it and the security will go off. With the key of course.

Most of the warning lights get power from the same circuit, and are grounded by their sending units, including the engine computer.
So if one warning light is out, chances are the problem is the bulb or the circuit board in the instrument cluster.

Most likely the brake interlock switch on the brake pedal is faulty or disconnected or the solenoid which holds the shifter is faulty or disconnected.
