Complaint Review: J D Byrider

My 2010 Chevy Equinox, just passed dealer warranty on mileage and time needed a new engine for which I was quoted approximately $ 7,000 from your predecessor.   
            - Not happy with this at all, I left the car sit on your service lot over a year while still making my monthly payments, while I was forced to purchase another car. 
            -  When i did finally attempt to resolve the issue, you worked with me on a re-built engine for $ 4,000 for which I was very grateful. 
             -  Less than 2 weeks later I dropped the car off to you again due to excessive noise from exhaust, the engine light on AGAIN, and it not shifting gears properly. (An issue I NEVER had before you replaced the engine) 
             -   I was told a few solenoids needed replaced, the exhaust manifold needed replaced and the transmission was bad.   You said the solenoids were covered under the engine warranty, and the exhaust manifold and transmission would cost me $ 1,300.   
              -  The second I drove the car off the lot after the above repairs, the engine light came on and the exhaust was just as loud as when I dropped it off.  
 
Where i am Today:
                 Today i dropped the car off at an accredited service provider and was told:
               - The engine light was on most likely because the oil was so low
               - The exhaust manifold was never touched (ie replaced). They said it was beat into place so bad that it is no wonder it was so loud.
