New R1T with 500 miles. 2023.46.0 release. Getting the System Fault Detected error…service required. No open service slots. What should I do? Drive or park it until I can get a service appointment?
Depends. How are you seeing available "service slots"? You should contact your guide and talk about it. Chances are all you have to do is a soft and/or hard reboot, but in the off chance that this is a serious issue you should be able to get service pretty soon, depending on your location and the nature of the problem.
I see you are in Seattle. The Bellevue service center is really good, but they have a backlog of appointments. If this is a serious issue they will get you in immediately.
I recommend you go into your rivian app and call the 24x7 support. They will likely walk you through a reboot process that might clear up the error, or, if not, help you get access to whatever service you require. In my one experience, they were super.
If you have some diagnostic tools like an OBD-II scanner, they can provide more detailed error codes, making it easier to identify the problem.
Also, I’ve heard that some car companies offer remote assistance services where technicians can help diagnose and sometimes even resolve issues from a distance.
