I purchased a FACTORY Trailer Tire Pressure Monitoring System for my fifth wheel. Factory TTMS system allows up to 5-6 different trailers per vehicle. TTMS allows owner to enter minimum PSI per trailer. The RAM factory system does not work as advertised. I paired wheel sensors to TTMS in vehicle and set minimum PSI to 100. When I shut vehicle off the preset reverts back to factory 50 PSI. Also TTMS recognizes 3 wheel sensors 50% of the time. The other 50% dashboard shows red lines instead of trailer tire pressure. I brought vehicle to dealership after creating a case file with Ram care #87574156. Case file was created due to numerous complaints of Ram HD forum 2019-2022 model years. Ram care notified dealer that no repair authorized without trailer being present. My Ram dealer parking lot is barely large enough for my Ram 3500. I notified Ram care and dealer that the issue was with vehicle software and not trailer sensors. After weeks of inaction from Ram care I was notified that the dealer must remove aftermarket trailer tire pressure monitoring system at my expense (6 hours labor) and only then could they repair system. I attempted to explain that I paid $500 for the FACTORY system but Nikkita from Ram care would not listen. Ram care has my VIN they easily check my vehicle options but their priority was to close case file and hope I would go away quietly. Ran care repeatedly closed my file claiming they couldnt contact me. All but three of my calls went to voicemail. I called Ram care and left messages on the following dates: 10/31/23 1703 hours, 11/3/23 1427 hours, 11/7 1510 hours, 11/24/23 1115 hours, 11/27/23 1255 hours, 11/29/23 0803, 0839 and 1540 hours, 12/4/23 1232 and 1242 hours. A follow up email was sent on 12/4/23 at 1110 hours stating Ram care was closing my case due to unsuccessful attempts to reach me. At 1258 hours on the same date I received an email stating the dealer must remove my aftermarket TTMS (emails attached)
