As noted earlier in this thread (post #392), the rear camera harness failure is being investigated by the NHTSA on 2017 and 2018 MY RLs. Every back up camera failure needs to be reported to the NHTSA. Especially those who have 2019+ MYs with harness failures. The website link to report the defect is shown below.
