Product: Vehicle loan or lease

I am filing this complaint because I was taken advantage of by J.D.ByRider and the CNAC finance company in XXXX FL. I was charged an extremely high interest rate for a XXXX used XXXX XXXX that has only a XXXX XXXX XXXX  value of XXXX at most, and that is if it is in superb condition. I was charged {$11000.00} for this car not to mention a finance charge of {$5900.00} and with interest included the price came out to be {$20000.00} for a car that initially was only worth XXXX XXXX. I am very upset with this company and angry, I do not even know how morally they could do this to anyone. They made it seem as if this XXXX was all we could afford and that our credit was very bad and it was not, we recently used the same credit scores to get a newer vehicle that is a XXXX in great condition with only 14 percent interest rate and no down payment. JDByRider charged us a {$3100.00} down payment and also took our vehicle that we had previously paid off and only gave us XXXX dollars for it! They are scam artists and liars, they didn't want to honor their service contract and warranty we had with them for the engine that was covered instead they found a way to blame us to get out of honoring their contract and fully fixing the problem free of charge to us. they never wanted to fix anything, and they barely maintained the car, our car was smoking the very first week we got it, and they gave me the run around for a few days and i was very mad about their service hours not being accommodating and by appointment only which made it very hard. They never wanted to call anyone back and many times i had to call continuously because they never wanted to pick up the phone. we took the car in to be serviced a few times, after each time the van it seemed as if it got worse and worse. My husband took the van in to be serviced and then maybe a couple weeks later the brakes started screeching very loud, my husband was actually told by a worker that JD, ByRider did not put the right brakes on the car but put cheaper brakes on that wear easily, and when I told them about this they didn't care they said they did their job and that we need to pay to get the right ones. Some time after that my husband started having trouble with engine it seems like right after we took it in maybe a few weeks later we are having issues again, this time the engine started overheating. So my husband is coming home from work and he is on the highway it starts overheating he said he pulled over let it cool down and then drove home and he told me and I called JD.Byride the next day. I had to schedule an appointment since they only work as their contract says by appointment only. In the meantime my husband took the car to XXXX XXXX XXXX and the fluid was very dry in the vehicle which is odd because we had just got the car serviced, which lets me know they do not properly do their job and inspect their vehicles when they are brought in, not to mention their was a leak in the radiator hose which was causing the van to overheat if the vehicle was properly checked when we brought in a couple weeks before I know they would have found the leak in the hose. My husband applied a piece of engine tape and he got the car to the appointment. We were floored when we found out that the engine that was covered in our warranty was completely bad and the whole thing had to be replaced and we were responsible for paying for a new engine which was supposed to be covered in our warranty. Their loophole was that we drove the car while it overheated my husband did not he let the car down and then he drown home, they said we should left the car on the highway and got it towed to them even though their service department was closed and by appointment only, which does not make sense to leave the van if no one is there. This clause is in their contract purposefully, to save their skin from paying customer repairs. I do not remember this key information but they did warn us several times that if we didn't pay our vehicle on time it would be shut off and they would come and repossess the very next day if we are late on just one payment. The CNAC Fiance Company has also yet to produce all the payment statements I asked for, for the time we had the vehicle, I thought it very strange that all the payment amounts did not show up on my payments statements especially the {$1500.00} dollar payment, I made directly to them in XXXX. All in all this has been the worst experience of my life, this has hurt my family, and if it does not get resolved it would hurt my credit we were hoping to purchase our first home this year and this has definitely set us back and I hope to get this out to at least someone that this place needs to be shut down for good! I do not want another family to go through what we have been through their practices are deceptive they prey on people and they try to pass off bad cars as if they are good, the try to also instill fear in you to pay them regardless of the situation they do not hold up on their end in the service department and they do not help their customers at all. Please Help!
