Hey all, I have been searching the forums trying to find anyone else who has had keyless entry & tpms issues pop up at the same time. My tpms acted up the other day, one side showed blanks for pressure while the other side had indication. Shortly after, all was blank and the keyless is unresponsive. I have checked all bcm fuses on both sides of the dash. All was fine. I then unhooked the battery for an hour. To my surprise and delight, all started working again. An hour later, same issues were back. I have found if I unhook the battery for a few seconds and hook it back up, the keyless starts working. However, if I start the truck and shut it back off, keyless returns to inop. I understand the "RCDLR" can be the issue? I pulled up my floormat and found the driver side soaking wet... maybe I do have the sharkfin leak and was unaware. I am a month out of warranty on this 2015 Denali ? If anyone has any input or knowledge on the issue, I would appreciate it. What would this fix typically cost? Thanks in advance.
