NHTSA Complaint #11643117 — 2018 RAM 3500

I filled a complaint on the HCU (brakes) on my 2018 Ram 3500 with NHTSA. FCA took forever to finally recall. By then i had already found a new RAM factorty OEM HCU from a RAM DEALER THAT ALSO SELLS ON EBAY, and installed myself. After getting the recall notice in the mail i contacted RAM as the part was already replaced to get reimbursed for same. I sent them the failure code from original incident, picture of the active light on my truck, ebay receipt from ebay with visa payment, and tracking showing it shipped to me. RAM Customer service replied the claim was denied because i showed no install. My email to them clearly stated i installed myself and have been in mechanical maintenance my entire carrer and was one of the first ASE Certified Mechanics in the 1980's. I believe they are not honoring the recall on my vehicle forced on them by NHTSA (thank you from all the RAM owners that they didnt care about) and i should be reimbursed for my cost and labor to install the known recalled failed part. When i tried to reply to the denial email they had already shut down the link. Im sure im not the only one with this problem. Thank you in advance.
