FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
On 4-5 occasions since purchasing a new 2021 GMC Yukon Denali the automatic breaking function has engaged for no reason, with no obstruction in the roadway. It has occurred at low speed (after disengaging break and starting to drive). Obviously, this is a major safety issue.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
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.

AIR BAGS
There are apparently a couple of faults affecting the SRS and leading to a periodic airbag light and "Service SRS" warning. GM has issued/revised a few Service Bulletins related to this warning. Some are related to software, some are related to overhead wiring, some are related to the clock spring in the steering wheel, and some are related to the driver's side airbag module. My understanding is that when the SRS warning appears, all airbags are disabled and GM says we drive our vehicles at our own risk. To my knowledge this has affected several models of approximately 2021-2023 GMC (Yukon and Sierra) and Chevrolet (Tahoe, Suburban, Silverado) SUVs and trucks.

STRUCTURE:BODY, UNKNOWN OR OTHER
While driving the car, the glass sunroof spontaneously exploded. It was NOT associated with a rock strike, no other cars were nearby, and the vehicle was not under an overpass. The noise was extremely loud, similar to a gunshot. The sun shade was closed, otherwise broken glass would have showered down on the passengers.

ENGINE, FUEL/PROPULSION SYSTEM
Twice in a five day span vehicle stalled out, acting like it is not getting fuel. Each time it took several minutes of trying to restart and getting below fuel tank to give it a couple knocks to get it to start. Both times there was atleast a half tank of gas. Each time the car was running well when it suddenly slowed down on its own, the first time I was on a busy street resulting in the need for a tow and I had my grand baby with me. The second time it was an isolated road and surprisingly I had cell service to call for assistance. The tow truck driver told me he thought it was the fuel pump. I looked up my vin but it isn’t listed as one of the affected vehicles in the GMC Yukon recall, however it certainly seems like it is. I had no warning of any type with each incident, the car simply acted as if it ran out of gas. I have an appointment with a local garage. Additionally when this happens the vehicle does not let me shut it off. The engine isn’t running but I can’t power down the electronics system.

Windshield wipers quit working. I turned off the rain sensing feature and they did not work even then. This is the second complaint I am filing on this vehicle. The vehicle is at the dealership for the second time to address this issue. Very very unsafe! they will work fine and then all of the sudden while it is raining they will stop working. Night time is the worst.

ENGINE
On March 15, while driving on a busy road our vehicle STOPPED from catastrophic engine failure without warning which put my family and I instantly in danger and nearly got us killed. Due to the high traffic where it stopped we were scared to stay in the vehicle and also scared to exit it .. so we contacted the police before calling a tow truck. When the police arrived, they parked a car in front and behind us and put their flashers on to make us somewhat more safer... we had the vehicle towed to the local dealership and contacted the actual dealership where we purchased this brand new vehicle with zero miles that was about an hour away and they sent soneone to get the SUV . Once they ran a diagnostic they discovered metal shavings in the oil and said it needed a new engine! What's alarming is that after hearing this we started googling terms like "Denali engine failure" "Cadillac ecalade engine failure" and discovered a huge amount of consumer complaints from other GMC customers on forums with their brand new GMC vehicles with little to no mileage and ALL had the metal shavings in the oil and shockingly needed new engines! FYSA- All complaints are on the 6.2 engines specifically. This is a huge safety issue as these vehicles are stopping in the road without warning. If someone doesn't do something I'm afraid someone is going to get killed. Please look into this and help us. We paid over $100k for a vehicle we no longer can trust. We were not given a police report but I'm sure the information about this incident is available by FPD since they were called and remained on scene with us for nearly an hour waiting on the tow truck. The dealership was great by the way, we do not blame them as we feel they are victims too. This is a GMC problem who are knowingly building and selling unsafe SUVs with the 6.2 defective engine that's literally stopping without warning while driving.
