I have been running my 2022 Lucid Air Dream Edition through a rail-based carwash since I received it in Jan2022. Probably about 20 times without any issues. I've run my 2018 Mercedes S560 though the same carwash (Crew carwash in Indianapolis) since I bought that vehicle.
However, the last two times I took my Lucid through the carwash, which was after a recall repair made at the Coldwater Michigan service center, the car shifted into park on its own causing much anxiety. The first time it did not allow me to move from Park into Drive. So the entire carwash shut down. Fortunately I knew how to reboot the software (Settings>About>hold "Air" for 15 seconds), and after a minute or two I was able to move the vehicle. The next time I tried to run my Lucid through the carwash, it got all the way to the end and then gave the same Frunk icon on the dash flashing, and the same issue. This time I tried to move to "Drive" and was successful, but only after shutting down the carwash for maybe 30 seconds. See the video below on what happenned.
The service manager, Jason Johnson, believes this is an issue with the software, and not water getting somewhere it should not get to. After the first time, they towed the car to the service center and "Found nothing wrong". But they did not try to take the vehicle to a car wash to replicate the issue. So I did that myself , and encountered the problem shown in the video.
I understand the risk to the paint, but I believe that is minimal. Other EVs can be run through a carwash. In fact, I saw that Tesla has a "mode" that the driver can turn on specific for carwashes, making sure the vehicle stays in neutral, closes tightly all possible openings, etc.
Anyone else have this issue with carwashes?
