The brake lines in my 2009 Cadillac Dts are completly corroded, to the point that they are leaking and need to be replaced. I never expected to see plain steel brake lines in a Cadillac, they should have been stainless steel at a minimum. In my opinion this is a safety hazard and should be addressed. The exhaust system is stainless steel and is not needed to stop the car. I bet Honda has stainless steel brake lines. No wonder that more and more people are buying foreign cars.

When traveling on highway my cruise control kept turning itself off and on. A driver traveling behind me let me know that my brake lights were staying on as if I were riding the brake (which I was not) and then would go off again - this kept repeating. It seemed this was why the cruise control was not working, as it would go off when it seemed like the brake was on & back on when the brake went off. I have since seen reports on line of this happening with other Cadillac and is a problem with the brake light switch. This is a safety problem as vehicles behind me do not know when I am actually braking. I feel there should be a recall but have not been notified of one, nor have I found one when searching on line. I have since learned that other vehicles (GM, but not Cadillac) have had safety recalls for this same problem.

I purchased my 2009 Dts Cadillac foley in Nov. Of 2008. Presently I have about 35,000 miles on the vehicle. I serviced my brakes about a year ago. There has been no sign of brake fluid leaking. In driving from Chicago North to highland park Illinois on the expressway, I had to make a sudden stop when the traffic suddenly came to a halt in front my vehicle. I was able to stop without an incident. On resuming driving, the brake pedal needed to be pushed to the floor in order to stop the car. I got over to the right lane and drove cautiously to my home and then took the vehicle to the service station where I had the brakes serviced. I was informed the brake fluid lines were corroded and were leaking. There had been no signs of leaking in my carport concrete floor. The service mechanic told me on replacing the two lines to the rear brakes and that all of the lines were ordinary steel. Apparently the sudden stop I made burst the corroded brake fluid lines. The service mechanic replaced the lines to the rear brake with vinyl coated lines, photo attached. My daughter and I could have been killed if I hadn't allowed enough space to the vehicle ahead for just sort of an incident. This is the third cadi that I have owned since your Oldsmobile division was eliminated. I would strongly recommend that General Motors issue an alert to cadi owners and other General Motors vehicle owners, of the need to examine the brake lines for corrosion. Further, if the present GM cars don't use coated brake lines, the coated lines need to be used. My concern is that other cadi owners need to be made aware of this situation. In my opinion, cadi needs to notify cadi owners that break lines need to be inspected if other are servicing cadi, if inddded cadi does break line inspections and to provide corrosion protected break lines.
