2025 Chevrolet Tahoe

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.

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.

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.

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.

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.
