The vehicle intermittently loses engine/ electrical power while driving. When the power loss occurs, brakes and steering lose proper functionality creating a threat to the driver and passengers as well as other motorists. The vehicle then is unresponsive to the proper starting procedure. Restarting the vehicle is inconsistent. It may start immediately upon command or it may cause a theft procedure to initiate. The vehicles dic will possibly show the following prompts just before the shutdown failure occurs; service vehicle soon, service stability system soon, service A/C system soon. During the shutdown failure, no electrical components are operable but power is still available to the car allowing the dic to prompt 'no fob detected' or 'theft attempted' and the fob will intermittently allow you to send lock/ unlock commands during the shutdown failure. The failure happens in any scenario and is intermittent in the aspect of no failure occurs for a week or 5 failures occur in a day. I cannot determine when the failures began happening considering I purchased the vehicle used with 155000 miles and the failures have been happening since day 3 of my ownership. The vehicle is currently at a midland michigan cadillac dealership being diagnosed.

Car was overhauled, the trans was basically rebuilt, with new components.problem with oil evaporating at very low mileage still an issue. ***no leaks*** or symptoms aside of diminishing oil every said set of miles. Very frustrating issue that hasn't been resolved.

While driving on the expressway( at night), going 70mph, the car completely shut down without warning. I lost all power, brakes, steering, lights. On dash message stated "accessory active" and then "shift to park." took the car to the dealer and they changed the throttle body and cam/crank shaft along with a couple other small things. Got the car back, and 1 week later, the problem began again but worse. It would do it repeatedly, at all different speeds. A couple of times right in the middle of an intersection! Took the car back to the dealer again and this time they changed the body control module. Got the car back and about a week later, the problem has returned!

The catalytic converter makes loud popping noises on passenger front side. Now is misfiring in cylinder 1 and also has unexpected gained speed without any gas peddle pushed. Gm extended the catalytic converter warranty to 200,000 miles due to converter problems. But my VIN they say isn't included. My car is a v6. My sister was the previous owner she said she never received any recall information. The website shows no open recalls but the work wasn't completed since she purchased in 2007. Gm website doesn't help at all.
