My vehicle started making a terrible noise. I had it towed to the nearest GM service center. It was determined that the vehicle, a 2023 Yukon Denali (less than 26000 miles) needed a new engine due to thrust bearing failure causing the engine block to be scored and contamination of debris internally.

I took my SUV (Yukon SLT 2023) to the GMC Dealership 4/5 months ago because of 2 recalls, Failed Brake Fluid Leak Detection and Serial Data Gateway Model. The car was repaired according to the dealership. About 2 weeks ago, I entered my garage to auto start my vehicle and my SUV would not auto start. I waited a few minutes and tried to start it again from inside the vehicle and it started. When it started, the engine light was on and on the dashboard, brake system failure was displaying. It was very strange. So, I let my vehicle idle for a couple of minutes and tried to move the car in the garage. The car started jerking when I put it in drive and a message displayed on the dashboard telling me not to drive my SUV over 40 mph. The brake system failure and engine light were still on. It was very strange. I parked my SUV and let it sit. I'm taking my SUV back to the dealership on Thursday. I'm thankful I wasn't on the highway traveling to work, who knows what could have happened. There are massive problems with these vehicles, brakes, engine, computer systems, etc. I do not feel safe driving my SUV. I drive 41 miles each way for work and I don't feel safe driving this vehicle now with all the recalls, including the engine.

Problem Synopsis: Camera Issues in 2023 Yukon Denali Vehicle Information: Model: 2023 Yukon Denali Issue Description: The vehicle's camera system exhibits malfunctioning behavior after the vehicle gets wet, such as following intense rain. Problem Details: Initial Trigger: The problem begins when the vehicle is put into reverse after being exposed to water, particularly following heavy rainfall. Observed Malfunctions: The driver's side camera ceases to function immediately upon engaging reverse. Abrupt braking while in reverse leads to additional failures: The passenger side and forward-facing cameras also go black. Temporary Recovery: The cameras intermittently resume operation based on the vehicle's movement: Stepping on the brakes causes all cameras to go black. The cameras come back online one by one when the car rocks back, likely indicating water displacement around electrical connectors or modules. Hypothesis: The issues are likely caused by water affecting the electrical connections or modules associated with the camera system. This hypothesis is supported by the cameras' behavior correlating with changes in the vehicle's position and the presence of water. Recommendation: A thorough inspection of the camera system's connectors and modules is recommended, with particular attention to waterproofing and potential areas where water might collect and impact electrical components. Attached Evidence: The attached document contains pictures illustrating the camera issues as observed during the malfunction. These images were taken immediately after the intense rain when the vehicle was put into reverse and during the subsequent camera failures.
