ELECTRICAL SYSTEM, ENGINE
My 2025 Chevrolet Tahoe Z71 3.0L LZO Duramax with approx. 3,380 miles experienced a sudden and complete engine failure while towing my camper on the interstate at night, in the rain, while traveling alone 375 miles from home. The vehicle lost power, displayed warnings, and became inoperable, forcing me onto the shoulder in unsafe conditions. The engine has been diagnosed as requiring full replacement due to a defective crank end play / thrust bearing, under Technical Service Bulletin (TSB) 25-NA-307. This is a significant safety concern for a new vehicle and could have caused a crash. GM has multiple documented issues with this model year, and the car has also experienced unresolved infotainment defects, as outlined in TSB #PIT6393F. Requesting NHTSA to investigate a potential safety defect.

ENGINE
I was driving up to a border check point and slowed down at the guard shack. Once cleared I released the brake and tried to accelerate. The vehicle shut down completely. I tried to restart it and the check transmission warning came on. The vehicle would not restart. I was blocking the lane at the border check. After a few minutes I was able to start the vehicle and limp over to the shoulder of the freeway. There was no power and loud knocking and squealing from the engine compartment. Engine light came on and several other warning lights that I don't recall. I was in the desert with 3 dogs in an unsafe area for 7 hours until I could get help. Vehicle was towed to the dealership and is currently under diagnosis but so far code P0016 and metal pieces in the oil.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When backing up the auto braking brakes very hard sudden stop without warning even though no objects near by. Appears to be from shadows and made worse when it is raining and the camera has water on the lense. I turned off the backup auto braking and it still does it. It brakes hard enough that it pinched a nerve in my neck causing sudden pain which chipped a tooth

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
After my vehicle experienced a brake system failure 3 weeks ago and I got my vehicle back from the dealership. I noticed that my vehicle has no emergency brake so in the event of this failure and/or future brake system failures there was no way to stop my vehicle. Their emergency brake is technically a parking brake that can only be applied when the vehicle is completely stopped. I'm not sure how a vehicle this unsafe would be even legally sold or allowed to operate on the roads.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS, SERVICE BRAKES
Brake system failure. Brakes were all but gone as I couldn't safely stop my car at an intersection and had to quickly cut in front of on coming traffic to go into a gas station to avoid running a red light.

SERVICE BRAKES
I am reporting a critical safety design defect in my 2025 Chevrolet Tahoe Z71 (VIN: [XXX] ), involving the Brake Pedal Assembly geometry. Bought vehicle in January this year and within a few days of driving I noticed my foot repeatedly catching or hanging up on the brake pedal when moving from the accelerator to brake, which severely delays braking application (regardless of my footwear). This momentary obstruction creates an imminent risk of collision during sudden stops. This happens at least once a week when commuting to work. The component malfunctioning is the fixed brake pedal placement itself. No warning lamps or symptoms precede the issue; it is a physical interference defect. The problem was reported to Courtesy Chevrolet in Phoenix, Arizona on 10/02/2025 (Service R.O. 694801). The service advisor verbally acknowledged the issue but stated it was a "factory design issue" they could not fix, explicitly referring me to GM for resolution. Other than myself and the dealership, no one else has inspected this issue. The pedals are available for inspection. The attached photos provide supporting evidence.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Driving along the highway in cruise control at about 70mph without any trailer being pulled. Suddenly I got brake errors. ABS, ESC, Trailer brake error failures all popped on the dash warnings. Brakes were unresponsive only applying hard pressure to the brake pedal was effective. There was zero feedback from the brake pedal to myself on it engaging and braking effectively. If this happened in a situation requiring more immediate braking, I would not have been able to figure out the braking capability of my vehicle in time. There were no issues with my vehicle at the time. I see that similar issues have been reported on Facebook "Chevy Tahoe Owners Group". Unknown whether it's a sensors glitch or a SW issue. After a few hours of being parked the car brake system started to work properly again. Made an appointment to check out they system at the dealership.

STEERING, ENGINE, LANE DEPARTURE: ASSIST
The vehicle is making a loud ticking noise which leads me to suspect this car has similar, if not the same issue as the 21-24 recalled L87 6.2 engines. I took it in the first time, they couldn’t reproduce the noise but I already have video documented footage over a few days with the sound of knocking/ticking from the motor. After they did an early oil change at the same mileage I brought the vehicle in for diagnosis, the sound completely went away. A few hundred miles later the sound has come back and the engine is knocking at idle. I have another inspection/ appointment this coming week for the vehicle. Additionally, the vehicle makes loud noises from the steering column after it has been turned off. It also seems to wander when driving the vehicle and the steering wheel assists cause the wandering within lane. It is very unsafe to drive this vehicle due to these two issues.

ENGINE
Bought the 2025 Chevy Tahoe, had about 680 miles on it. 400 of which were from the dealership. Had the pleasure of driving it for a week. Check engine light came on and was told that the transmission valve body had gone bad. The issue regarding that particular transmission has existed since 2019. However the part needed is allegedly on back order, and GM has no idea when they will get that part in.

ELECTRICAL SYSTEM, SEAT BELTS
I was driving and the driver dash frozen. I couldn't tell my speed, it didn't indicate blinker or hazards. It would say i was in "D" when the car was parked. The center dash shut down completely. The seat belt indicator didn't work, none of the charging ports worked. **THIS IS A RENTAL CAR**** I do have video of the dash.
