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.

After driving on an Interstate Highway for approximately 2 hours I exited and brought the vehicle to a complete stop at a stop sign while preparing to turn right onto a busy 2-lane road. I applied moderate gas pedal pressure and the vehicle momentarily accelerated and moved forward but then the engine stalled as the transmission was attempting to shift automatically from 1st to 2nd gear. The vehicle was partially stuck out into the busy road without any power. This created a traffic conflict and near-miss with cars traveling along the 2-lane road that I was attempting to turn onto. I restarted the vehicle and drove it slowly onto the shoulder. The vehicle-??s engine repeatedly stalled any time enough gas pedal pressure was applied to cause the transmission to attempt to shift from 1st to 2nd gear. This issue only occurs after the engine and transmission have been running at operating temperature for several minutes. The dealership could not duplicate this issue, but they only drove the vehicle a total of 7 miles over two different occasions. The vehicle was purchased new on June 23, 2023 and had approximately 1,700 miles on it when the issue first occurred. There were no warning lights or messages illuminated prior to the engine stalling. Vehicle is currently at a dealership service department being evaluated.
