Hello, I am XXXX XXXX. 
I purchased a car from Byrider  in XXXX Ohio back on XX/XX/XXXX. XXXX. 
The car was sold to me with a bad engine. 
Started XX/XX/XXXX Tuesday morning. 
XX/XX/XXXX. Took car to friend of my brother in law. XXXX XXXX works for XXXX XXXX said engine going bad.Engine light will keep coming on and off until repaired or replaced. o whom this may concern, NEW Acct # XXXX XX/XX/XXXX. 
This certainly puts XXXX XXXX your vehicle you sold me.I am requesting a refund in the amount of {$200.00} cash as soon as possible due to the fact that your dealership sold me a illegal car that has a bad engine in it and NEVER should have been SOLD! 
Totally not cool. 
I am now without transportation and have paid you money I have no way to get back-and-forth to work.I must have a safe dependable car to work with XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXXXXXX XXXX XXXX XXXX XXXXXXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX, they have also saw the car with the engine light on and has informed me that I can not drive their students back-and-forth to school with an unsafe car!! 
this is a major problem that you all have put me in for no reason and all I did was come in to buy a car I will not stand for this! I have asked my lawyers to seriously intervening with this I will not pay {$17000.00} including XXXX finance charges totaling up {$30000.00} for a car that has a bad engine in it that shouldnt have never been on the market for sale.under the lemon law this is illegal and seriously unethical and I want my money back. 
I have forwarded over this complaint to my attorney, federal trade and consumer protection agency asking them to also intervene to get me back my {$200.00} cash down payment back asap! 
the deposit down payment was a total of {$500.00} back on XX/XX/XXXX, XXXX decided to stop payment on a {$300.00} check due to this horrible situation. 
I will not be purchasing a car that has an engine light come on three days after purchase. the engine light in the XXXX XXXX XXXX remained on the entire week after purchasing on XX/XX/XXXX. 
On XX/XX/XXXX, I did have a friend that works as a XXXX for XXXX XXXX 20 years personally do me a favor and look at the car this past Monday XXXX XXXX mechanic from XXXX XXXX that also has his own auto body shop basically told me that someone purposely fully reset check engine light which is illegal! 
The gentleman that looked at the car saw the engine light on said he would not reset the code to the bad engine light on the car your dealership sold me because I did not buy the car from the company he works for which is XXXX XXXXI have also posted the photos to show your Finance company enough proof that the bad engine problem does exist! 
I have already lost two days work and two days pay! Please return my funds so I can purchase another car.I would like a refund because I no longer trust ANY of your vehicles on the BYRIDER LOTto be working safely and properly thank you. 
Swindling a customer is totally unethical and after reading your XXXX reviews and seeing previous remarks about your BYRIDER CAR COMPANY on various LOCAL media news TVI will not toy with this! I am also going to contact the attorney generals office and Ohio and ask them to close your doors! This is really bad! you have 24 hours to issue my {$200.00} cash refund payment.I sincerely want no trouble I just want my money back and walk away which I feel as a customer I am entitled to do.lets keep this mute so this does not get big and awful and cause you guys a great deal of embarrassment.. a simple refund would do. 
Respectfully.
