Hi all,

First post here so hopefully I am doing this right.

I have a 2025 CT5 that has intermittent issues with the internal GPS not knowing where I am (thinking I am 20+ miles away from my actual location). I took it to the dealer and since they said they couldn't recreate the issue, they updated my software and sent me on my way, but the issue continues. Anecdotally, I noticed the issue right after taking it to a car wash and then again a few weeks later after having a few days of rain, so I think water is getting under the shark-fin antenna and possibly screwing with things, but I am not a mechanic and it is just a guess.

Has anyone ever dealt with this? I couldn't find anything related to GPS issues in any of the TSBs and search on this forum didn't come up with anything.
