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.

Steering wheel makes thump/clunk sound when turning or going over bumps which causes steering wheel have wiggle/loose. Steering wheel is also making rubbing sound when wheel is turned slowly in any direction. I had my local dealer look into this and they concluded that wheel needed to be greased. The thump/loose steering wheel problem continued and I ended up taking vehicle to another Cadillac dealer nearby. I explained to advisor of continuing problem and informed them that another dealer attempted to repair. I was told by advisor that problem was worn tires. I explained to advisor that vehicle had this problem when car was purchased with new tires. I replaced the tires two months ago per dealer's recommendation and problem is still continuing and getting worse.
