COPART On 7/5/2023, I bought a vehicle from Copart auction in Michigan. 2022 AUDI Q5 PREMIUM for $29,634.00. The vehicle was advertised as a clean title and sold to me as a Clean Title with minor front-end damage only. CARFAX reported the vehicle as a total loss salvage title. Dallas, Texas

Whether the title is salvage is determined by what's on the title, not by Carfax.  Does your certificate of title say "salvage" on it?

You seem to be extremely confused about the role an auto auction plays.  The previous owner of the car got in a crash and had the insurance company repair the car.  They then either traded it in to a dealership, or the insurance company paid out the car and took possession of it.  They then sent the car to the auction.  Copart's role in this is administering the auction, not anything else.  They may have no idea who owned the car before and what insurance company they used.

If the title says "salvage" and they claimed it was clean, then they committed fraud and you should be able to either reverse the transaction or get them to compensate you (subject to whatever waivers you may have signed).  If the title is clean and Carfax reports that it's not, then it's between you and Carfax.  They should be able to tell you who reported that status, and you would have to sort it out with that entity.

I filed a complaint with Carfax requesting an explanation of why my Clean Title car was reported as a Total Loss vehicle.  Carfax instructed me to have Copart/Insurance company send copies of the document used in selling the car, they gave me a reference number as shown. consumerresearch@carfax.com .  REFERENCE CASE# XXXXX65 TOTAL LOSS TO: ATTN: Bianca Resolution Manager CARFAX, INC.                                               Carfax wants Copart/insurance company to send them copies of the initial documents for the car. I do not understand why Copart refuses to send the requested documentation to Carfax. I wrote to Copart more than 5 times on this request, but still no resolution. Please note, that a vehicle can not be branded as Clean Title and Total Loss at the time. 

If your car has a clean title, it has a clean title.  If it doesn't, the title will say "SALVAGE" on it.  It's possible someone committed fraud at some point and washed the title, or perhaps the damage didn't meet Michigan's thresholds for declaring the car a total loss.  Unless Copart is the entity that reported the car as a total loss to Carfax, I don't really see how you could argue that they owe you anything.  But I'm pretty sure they didn't, they are just an auto auction.  Usually this type of history gets reported by insurance companies.

I wrote to Carfax regarding the total loss report on the car. Carfax told me to have Copart/ insurance company send them copies of the documents for the car.  I contacted Coparts to work with the insurance company to send Carfax the documents REQUEST but Coparts refused, they also refused to give me the contact information for the insurance company, stating that it was against their company policy. 

Generally, under Michigan law, if the vehicle is 5 model years old or newer at the time of the loss, and the estimated cost of repair is at least 75% or more of the vehicle's pre-crash fair market value, then the title must be branded "salvage." Michigan, has what is known as "title branding laws." These are laws that require vehicle titles to be branded "salvage," "scrap," "Total Loss," "rebuilt" and the like, depending on the age of the vehicle and the extent of the damage.
