I have a 2018 RAM 2500 Cummins Diesel & have been having problems with my U-Connect every winter! To explain: when the temps reach 28F or colder, I loose SXM, heated steering wheel/seats, NAV, Bluetooth. Sometimes, I can control heat/def from the NAV screen but the control buttons below the screen will not work (u press the button & the light will come on for about a second & go out). Sometimes I can control the climate from the NAV screen & then sometimes the climate goes out!
I reside in NC & the temps may/may not reach 28F or colder, so this issue has been going on for (4) yrs now! Yes, the dealership has been able to see the problem but so far, they haven't found a fix for it. I had to contact Chrysler/RAM (x2 yrs now) to escalate the problem. This past April, Chrysler auth the dealership to replace the entire NAV/Radio to see if that would rectify the problem & unfortunately, it didn't. So far, I have taken my 2018 RAM 2500 CD (still under warranty) in for service on this problem x5! I only have my truck to drive & Chrysler/RAM contacted me by email to tell me to take my truck back into the dealership (even though they have no loaner to give me) & Chrysler/RAM would give me $40 per day for a rental. We'll we all know the current rental situation due to COVID-19 and "if" I can even find a rental, they want $130 per day!! I responded to Chrysler/RAM & said it was totally unacceptable & they should provide me a loaner at "no" cost to me due to the fact that I have already spent quite a bit of my own money on UBER, lost time-off work & plenty of stress/anxiety dealing whit this for (4) yrs now!! You guessed it, Chrysler/RAM never responded to my email request!
