1PE22006 · Rear-View Camera Failure
Opened Jul 22, 2022 · Closed Nov 21, 2022
Status: closed (inferred from source dates) · Back Over Prevention: Sensing System: Camera
On July 22, 2022, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE22-006) to assess alleged failures of the rear-view camera (RVC) in Model Year (MY) 2020-2021 Cadillac XT5, XT6, and GMC Acadia vehicles. The complaints report that the screen for the RVC is black, sometimes with a red triangle and a circle with a line through it. To date, ODI has received a total of 18 complaints and several EWR Field Reports with allegations of the RVC image failing to display when the vehicle is in reverse. The reports have been received over the past 28 months with most occurring with low vehicle mileage.During the investigation, ODI learned incorrect crimping specifications were utilized in the production of the coaxial cable connector. Improper crimping leads to loss of connection between the RVC and dashboard screen that results in failure of the RVC image to display. Failure or malfunction of the RVC image to display results in reduced visibility of the area behind the vehicle. This limited view may lead to an increased risk of incidents resulting in injury and/or property damage while the vehicle is in reverse.The improperly crimped connectors were only present on subject vehicles equipped with the optional RVC surround vision feature (UV2). Vehicles not equipped with the optional RVC surround vision feature were not affected by this failure. On September 28, 2022, General Motors (GM) filed a defect information report (NHTSA number 22V-709) recalling certain MY2020-2021 Cadillac XT5, XT6, and GMC Acadia vehicles equipped with the optional RVC surround vision feature (UV2). GM will replace the coaxial cables with properly crimped connectors.In view of the recall action being taken by GM, ODI is closing this preliminary evaluation. NHTSA reserves the right to take additional action if warranted by future circumstances. The ODI complaints cited above can be viewed at www.nhtsa.gov.
