Thank you for your reply.Did the message remain until you shut down? Or was it momentary?
Did the message reappear after restart?
Has your start/stop been working?
When did you take delivery of your '17? Is it more than 4 years ago?
Yes, the start/stop worked before installing the LED bulbs.The start/stop not working is a telltale that there is an electrical issue or cooling related as symptoms have been reported on this Forum for the past 4 years.
Did the start/stop work before you installed the LED's? If you reinstall the OEM bulbs and your start/stop begins working again, that may have caused the Driver Assist message as well.
You are a couple of months out of the Bumper-to-Bumper warranty, but you could go to your dealer if the Driver Assist message appears once again to have them read the code that was stored. You should have a couple of days while it is retained in memory. If they do not cover the repair under warranty, it would be good to know what is causing the problem. They may do a courtesy extension of the warranty if you go there regularly.
Problem is the code readers at the auto parts stores do not read all of the specialized codes the dealer scan tools read. The auto parts code reader will likely say no codes.Also, if the dealer won't read the codes for free, go to a local chain autoparts store like Advance Auto or AutoZone and they will do it as a courtesy.
