Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Backup camera is very dim especially on the very outside of the view. Not bright enough to discern pedestrians walking behind the vehicle which could possibly cause bodily harm. Dealer says it is within their specifications and there is nothing they can do. I've found several forums on this very subject and some claim there is a fix using a computer program that lightens the camera to a useful level. I took this issue up to their customer care and they say the dealer can't do any more and the case is closed. …”

The sound appears to come from the drivetrain area and raises concerns about a potential driveline or mechanical failure at speed. The issue has been reproduced and confirmed by multiple authorized dealerships. The vehicle has undergone two rear differential replacements, a transfer‑case replacement, chassis ear testing, STAR engineering cases, and testing with OEM wheels and tires. …”
