Trouble code U164F
Has anyone encountered DTC U164F - lost communication with telematic control module on CAN bus 5?
No CEL and everything seems fine otherwise.. periodic soft close frunk issue, bot don't think it's related.

These weird codes that don't seem to affect the drivability can sometimes be cleared with emptying the digital cache. EZ, free, and worth a try.
