“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.”

NHTSA complaint #10823262, filed 2016-01, 35,000 miles“When traveling on highway my cruise control kept turning itself off and on.

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 cadillacs and is a problem with the brake light switch. …”
