Product: Vehicle loan or lease

On XX/XX/XXXX, I deposited {$6000.00}, to the account of XXXX XXXX XXXX, XXXX XXXX XXXX XXXX XXXX , CO XXXX, as the down payment for the purchase of a used XXXX XXXX XXXX with stated manufacturers power train warranty expiring on XX/XX/XXXX along with XXXX report prepared by the dealer. .XXXX XXXX XXXX. XXXX XXXX then prepared consumer loan in the amount of {$32000.00} for my son to take delivery of the truck, the note was given by Santander Consumers, USA, XXXX XXXX XXXX, XXXX XXXX, TX XXXX. The note was to cover the following, mandatory warrants ty in favor of Santander in the amount of {$2700.00}, Colorado sales tax {$2800.00}, leaving an amount financed of {$29000.00}. The VIN number of the vehicle is XXXX. 
Upon delivery the left front tire deflated in the dealers parking lot. The vehicle was left overnight while the dealer repaired the tire. The truck was picked up the following day and within the first hour the engine malfunctioned and seized up. I had the truck towed to XXXX XXXX in XXXX, CO where a complete diagnostic was performed. The report stated that the truck had a leak of engine oil into the power train and that there was a near complete migration of the oil away from the engine resulting in the seizure and a new engine costing was required to bring the vehicle back into service. When confronted with the engine seize up and the recommendations XXXX XXXX refused to allow any warranty work to be done at XXXX. XXXX XXXX demanded we pay the expense of having the vehicle towed back to them for where they said the problem was a defective fuel pump and they replaced it with a used one covered under the warranty. The truck ran for about a hundred miles and the problem was repeated. 
My son and I made a series of inperson and telephone demands to have the engine replaced. We were constant, y rebuffed. I retained an attorney who presented manager of XXXX XXXX with irrefutable data from XXXX showing that unauthorized work had been done on the truck in XX/XX/XXXX and that the powertrain and other warranties were voided by XXXX I. XX/XX/XXXX. Sharper rides made a false representation in their sales papers that the power train warranty was valid until XX/XX/XXXX. They have refused to respond to requests for warranty work. Most recently the warranty company refused to reimburse me for {$2300.00}, to repair the oil leak from the engine to the power train. This work was done at. XXXX XXXX. In the year since delivery we have complained to Santander about the material non disclosure and they have not responded. The warranty rep refuses to anything and totally ignores the the diagnostic report from XXXX and XXXX. The report still stands that the engine was subject to unauthorized work and there are permenant deficiencies in the timing mechanisms and other matter that XXXX detected in XX/XX/XXXX, the code deficiencies run to two pages and these conditions existed three years before XXXX XXXX sold us the vehicle. Both Santander and XXXX XXXX and the warranty company were sent copies of the presage deficiencies which were not disclosed at the time of purchase. 
XXXX XXXX is a highly reputable Dealer and they have a long history of fixing XXXX vehicles for owners that purchased them at XXXX XXXX where in general a minor repair was made where a major one was required. In our case XXXX said the fuel Pump was operating as it should and XXXX degraded the engine by replacing an OEM part with a rebuilt. 
We have tried to get the theee parties to the table or arbitration and we are just stalled. 
I have spent, over {$6000.00}, inrepairs, towing, and. Car rentals. Tne truck has been driven about 1,000. Miles since purchase and been towed at least twelve times. 
Please assist us in bringing these parties to the table so we can resolve matters.
