ESC & Stop/Start Malfunction

[Winnipegjet301]

Long story short I've had this issue come up randomly and recently (today again). I have a 2022 RAM 1500 BIGHORN/LONESTAR CREW 4X4 (144.5 in WB 5 FT 7 IN box) with the V8 Etorque engine. Randomly the ESC and Stop/Start malfunction would go off. About 4 months ago was the first time I was driving home it was a wet day, then it happened again a month later twice in one day (But it wasn't raining i don't think). So I brought it to the local Ram dealer, got it diagnosed and they told me it was a Vacuum pump and/or Vacuum sensor most likely. Paid $250 for them just to diagnose that. I was sceptical but I bought the parts and put them in about a month later (myself). In-between that time I didn't have a issue again. Today (about a week later), rainy day the malfunction goes off again on my drive to work. Clearly it was not a vacuum pump or sensor. I'm thinking it has to do with water immersion somewhere, maybe a wheel speed sensor? Also I've had water immersion issue before about a year ago causing the ABS and Stop/Start system to malfunction, but got that fixed after the 4th time bringing it to the dealer (again another intermittent problem).

Has anyone else had similar issues?

Did the diagnostic paperwork from the dealer show the actual trouble codes? Or have you had the codes pulled by someone else/yourself? Even if they aren’t active, the history codes may show the problematic components.

So this is what the paperwork said "Had faults U120C for lost break booster signal and C1082-02. Vacuum pressure sensor tested Vacuum pump is very noisy recommend replacement of the vacuum pump and sensor."
