Defect investigations

Rear-View Camera FailureOpened July 22, 2022, closed November 21, 2022

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 (the federal safety agency 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. the federal safety agency reserves the right to take additional action if warranted by future circumstances. The ODI complaints cited above can be viewed at The ODI identification numbers for the complaints cited above can be found below: 11343838, 11390254, 11406709, 11415261, 11415501, 11425365, 11429267, 11431846, 11446363, 11463278, 11463901, 11471702, 11475437, 11476809, 11477176, 11481806, 11484360, and 11484360.

UNACCEPTABLE SAFETY HAZARD: General Motors & Cadillac Need to Take Responsibility I am writing this to urge Cadillac and General Motors to address a critical safety issue before someone gets seriously hurt or dies. While driving my 2020 Cadillac XT6 over an overpass in XXX, the vehicle suffered a complete electrical breakdown. Every dash light flared up, and I instantly lost total control—NO steering assist, NO acceleration. Being stranded in a moving vehicle without control on an elevated roadway was terrifying. This car has under 50,000 miles. It is currently on its 6th service visit at Stevens Creek Cadillac and has been sitting in their shop for 3 full weeks with zero answers or progress. I trusted Cadillac again even after my 2006 SRX had to be donated under 150k miles following 2 transmission replacements and endless issues. But experiencing a sudden, total power failure at highway speeds crosses every line. I am fearful to take this vehicle back. I do not feel safe put back behind the wheel. GM and Cadillac really should not sell these vehicles until their electrical issue is safe. I opened a case with GM and they said that the buy back was denied which is insane to me. this vehicle doesn't even have 50,000 miles on it. I hope someone will help my husband and I. thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle stalled while driving on a busy road creating a very dangerous situation. Could not put it in neutral to push it out of the road; it was partially in the road for over an hour. Had to have it towed to replace the fuel pump and fuel pump control unit. Found two recalls after the incident and was told by Cadillac that my VIN was excluded. 1.

at 60,740 miles, "Steering Assist is Reduced Drive with Care" message appeared. Under warranty, but dealership booked for 2 months. Error went away. After powertrain warranty expires (70,000 miles), message constantly appears, and coolant thermostat display is BLANK. Results in excess fan usage (lowering fuel consumption), reduced steering assist, aggravation, check engine light. This issue has developed while under warranty, for a practically new car. Unacceptable. An extended warranty should be in effect for model 2020 as well.

The engine cooling fans also run after the engine is switched off. A recent bulletin has been posted to the 2021 Cadillac XT6 but is present in our 2020 as well.
