Tl* the contact owns a 2007 cadillac dts. The contact stated that an independent repair facility had been informed more than once that the oil pressure warning indicator illuminated several times.

While driving at an unspecified rate of speed, the oil pressure warning indicator flashed, there was a sudden loss of power, and the brake pedal was stiff when depressed. As a result, the contact crashed into the rear of an 18 wheeler. The driver sustained minor bruising and pain to the shoulders and forearms. Medical attention was received.

The manufacturer was notified of the crash and the contact was awaiting to determine if they could conduct an investigation. The VIN was not available. The approximate failure mileage was 119,000.

This problem - the car dies and I lose all power assisted functions like steering and brakes - has happened multiple times, probably two dozen, over a period of time beginning some time in 2006, with model years 2000, 2001, and 2006 sedans. Since 1995 I have driven only cadillac. It occurs only when I'm stopped, or rolling at a slow speed, and then begin to accelerate the car, such as has happened many times when I'm in a non-raised center median attempting a left turn against oncoming traffic (I have learned to left lots of room now). I hope I, or someone else in a cadillac, won't have to die or be seriously injured before they admit this problem in their flagship vehicle. I called gm's 'ignition switch recall' line and was told that this sounds exactly like the problem in the other vehicles.
After experiencing a loss of power steering, I took the vehicle to vera cadillac in pembroke pines, florida. It was determined that the power steering hose was leaking at the crimp. Also, the fluid leaked down to the serpentine belt which sprayed the fluid all over the engine compartment. The hose and the belt were replaced at my expense (over $500). I knew there was a recall (the federal safety agency campaign id number 06v105000) for this vehicle concerning this exact problem but I was told that based on my VIN that my vehicle was not included in the recall. Based on the amount of complaints I've read online from people who have experienced the exact same scenario, I find it hard to believe this is a coincidence. I have the exact same vehicle with the exact same failure as stated in the recall. My vehicle was manufactured on 2/06 and has very low mileage. Someone needs to investigate why these other vehicles were not included in the recall. It seems to me that someone simply made a mistake when gm first investigated which vehicles to include.
Tl* the contact owns a 2006 cadillac dts. While driving at 55 MPH, the vehicle began to lose power but did not stall. The dealer advised the central computer was defective and was failing. The dealer made unknown repairs to the vehicle. The failure mileage was 5,000 and current mileage was 23,100.
