general problems of the 2006 Cadillac SRX

Oil sensor unit failure causing engine to lose oil. A realproblem.

About 3years ago the dryshaft went bad on my 2006 Srx. I asked the dealerships service manager was it a recall on the part and he said "no. "I search for months after driving my car with the bad ride from the bad part and being limited for over 2yrs with not knowing, I finally got a used dryshaft for my car and now about 6 months later on Wednesday 8/8/18, I pull off at the light and it feels light something knock something underneath my car. I get on the highway and this loud noise happens. The next day I take it to meineke and this one is gone bad. I search the net on recalls for my car and there it is. Now the dealership in my state is telling me that my car is not eligible because it already had the recall done before I purchased it in 2008. Its the same part that goes bad on the car and its still going bad. Its your recall part period. Please tell me that you will replace it. Please contact me ASAP! thank you.

First started hearing problem when  I purchased SUV back in June 2012, I took it to dealer several times within days of purchasing the SUV and they would not fix it, they wanted to charge me $1600. 00.   warranty would not cover it because they said it was a exsisting condition. So, thats the first issue I have. Now, the same issue got worse (@ 108,000 miles) and became a safety issue and I noticed the same problem was in the recall info from Dec 2007 on the lemonlaw site. July 17th 2014 I took my SUV in for repair on another isssue, then on the 19th I called the dealer cause I started to hear a whinnng noise and a clunk sound that was even louder than before. That same day as I was transporting a client coming out of a parking lot my car suddenly jerked so hard my client almost bumped her head on the dashboard and me on the stirring wheel. After having it towed to another Cadillac dealership nearby I was told that it was the differential pinon/ bushings all the fluid had leaked out and when the tech showed me what happen all bolts were missing that suppose to hold parts together. So, I asked does that happen over a period of time and he told me no it doesn't and hes never seen that before. So, now I am very suspicious, confused and angry. The repair is going to cost $3,000, they said with no way around it, I did buy the car used but I feel that this issue should be covered by the manufacturer and/or dealer. There were other issues that I had with the SUV that was taken careof, they called it special codes but they left this one out. Please help, I have elderly clients/family/ friends that I care for on a daily basis and I need my SUV.
