Product: Vehicle loan or lease

On XX/XX/XXXX I purchased a used vehicle from XXXX XXXX XXXXXXXX, I asked specifically for a warranty that would cover motor/engine repairs. I was sold a warranty for {$3100.00} with the warranty company named XXXX XXXX XXXX listed on the purchase agreement. I was told by the dealership that this was a 3 year vehicle warranty that would cover mechanical issues and any major repairs needed within that 3 year time frame. 
Several times after purchase I took the vehicle into the service department for check engine light being on, I was told it was the type of gas I was choosing. I also let them know of a major problem I was having where the vehicle would suddenly shut down on places like the interstate, in extremely dangerous situations with my children in the vehicle. I was never helped and they seemed to not care about these serious issues. 
On XX/XX/XXXX I took the vehicle to XXXX XXXX XXXX of XXXX for overheating and coolant leaking. I said that they could complete an oil change while I was there and asked that they contact the warranty company in hopes that the coolant hose replacements would be covered. I was contacted via text message to let me know the fix would be {$1100.00} and was not covered by my warranty. He did let me know that there was a pinion seal issues that my warranty would cover. He also let me know that during the oil change they stripped the threads and now my oil change would be a total of {$1500.00} which was their own mistake. I told them I did not want any of the repairs done and that I would come get my vehicle. At that time, I was told I was not allowed to come and get it, basically trying to force me to agree to the charges. After getting some advice from another auto mechanic shop and having to bring a male with me so that I would not be bullied at the dealership I was told they were able to put a band aid on the oil issue that they caused and that I could drive away with my vehicle. I contacted the company listed on my purchase agreement with XXXX and was told I do not have an active warranty with them. XXXX of XXXX is unable to help me resolve these matters and when I called Ford Motor Company corporate I was directed to have this issue resolved at the dealership in which I purchased the vehicle. Despite taking my vehicle to XXXX XXXX XXXX regularly for multi point inspections I am being told by other auto mechanic shops that there are multiple severe issues and they are shocked that these issues were not discovered and addressed a lot sooner and will cost me thousands to fix without the warranty coverage. I believe that my vehicle has not been properly taking care of at XXXX XXXX XXXX because they knew there was an issue with the warranty that I was sold and they are attempting to cover this up. I have called to get copies of documents and have been told they do not keep digital copies, it's really hard to believe a big dealership does not keep digital records of their sales. I believe I was sold a vehicle with severe mechanical issues and lied to about the warranty coverage. I do believe that XXXX of XXXX XXXX and XXXX XXXX XXXX has purposefully committed fraud and I wish to pursue further action against Ford Motor Company.
