My 2021 Acadia digital dash goes out (completely black). I took it to the dealership on Friday August 25, as the issue was happening more frequently. I was told the software was not current. This was attributed to parking in a garage each night. Yesterday September 22 while driving, the dash again went out for a much longer timeframe (several miles). I called the dealership. Service was closing but was told by the receptionist that one of the sale people said to (1) park the car, (2) turn off the engine, (3) open the drivers door and leave open for 5 minutes to reset the system and everything should be fine. The black dash prevents the driver from seeing current MPH. I am uncertain if it also disengages adaptive cruise control and auto-braking. Is it acceptable for the digital dash to routinely go black while being operated? Is there a more sustainable resolution for the dash going out? Thank you!

Driving at 70mph on Interstate 69 near Charlotte Michigan at around 10 pm on Wednesday 8/23/2023. Passenger side front tire suddenly deflated. Limped the SUV into a store parking lot at interchange. Continental 235/65R18 106H tire was changed by road side service and spare installed. This morning , while examining tire and rim , found two long radial cracks approximately 50 to 75 mm in length on the outboard surface of the tire. The cracks are about 90 degrees apart. The vehicle has just under 34000 miles on the OEM installed tires. The reason I am contacting NHTSA is that the cracks do not look like road hazard/debris, rather a split in the sidewall. I have not taken the tire back to the dealer or a tire store. I did photo document the failure and cracks.

The IPC goes out while driving. GM is aware of this issue in several models they make starting in 2020. They failed to call a recall on the issue and when you take it in to be looked at there is a service bulletin out to have the dealership to do a software update on the IPC to resolve the issues that some customers may be experiencing. This issue costs 189.99 to diagnose the first hour then the dealership spends another 2.5 hours diagnosing the known issue to charge customers for a total of 3.5 hours in repair costs. GM does not assist in anyway with covering the cost of the repair to the vehicle that is a 2021 make and model. In all to make your car safe to drive again the repair costs 474.88 and there is no guarantee after the software is updated that the issue will not come back and then I will be left with taking it back in for troubleshooting to be charged another 474.88 as long as the price does go up for electrical diagnostics charges. It’s pretty convenient on GM and their dealerships to charge customers a to fix a safety concern that can happen again and charge 3.5 hours of labor charged even when there is a service bulletin out telling repair technicians to do the software update when a customer stated the IPC goes out while driving and comes back on. If there is a know. Issue then my issue should be been resolved with just having to pay for time it took the repair technician to do the software update. Not waste time tracing all wiring just to run up all labor rates first.

PE22006 · 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. 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.
