I am filing a safety complaint regarding my 2025 Chevrolet Tahoe premier for repeated brake assist/braking failures. Most recent incident: while driving, the check engine light came on. I turned the vehicle off for approximately 10 minutes and restarted it, but the check engine light remained on. Approximately 20 minutes later, multiple warnings appeared on the dash including: “brake assist failure press hard to brake,” “speed limited,” and “service esc. ” at that point, braking ability was severely reduced. I was close to my destination and approached a stop sign. I intended to roll through the stop sign because the brakes were not functioning normally, but another vehicle suddenly approached. I pressed the brake pedal with both feet. The brakes were stiff and hard to press. The vehicle still did not stop properly and came to a stop in the middle of the road past the stop sign. After arriving at my destination, the vehicle sat for approximately 1–2 hours. When restarted, the brakes appeared normal again, but the check engine light remained on. In the mychevrolet diagnostics app, it then showed warnings for engine and transmission system, transmission system, and four wheel drive system. While driving to the dealership afterward, the vehicle also began shaking. This same issue previously occurred on April 16, 2026. I was driving on the interstate when the brakes lost assist and the dash displayed “service esc,” “brake assist failure press hard to brake,” and “speed limited. ” after reaching my destination, I was told by someone at the dealership to turn the vehicle off for 10 minutes to see if that would fix things, so I turned the vehicle off for about 10 minutes. When restarted, all warning lights were gone and braking returned to normal. I still drove the vehicle to the dealership that same day for service. This is a repeated, intermittent brake failure / brake assist failure creating a serious safety hazard and near collision risk.
On March 21, 2026, I rented a Chevrolet Tahoe (approx. 24,450 mileage driven). While operating the vehicle on a freeway at approximately 40–50 mph, the braking system and abs failed suddenly without any warning. Barely no brakes were able to apply to stop the vehicle. It also started to show that ecs service (electronic stability control) and service brake pad monitor. Many faults started to show.
I have a 2025 chevy Tahoe and the automatic braking system is way too sensitive. When I’m reversing, it constantly slams on the brakes even when I still have enough space and nothing is in my way. It also brakes when people are nearby but not actually in my path. One time I was stopped and about to move forward, and the car suddenly braked because a construction worker was a few feet away, not in front of me. It caught me off guard and didn’t feel safe. The braking is very sudden and aggressive, and it makes normal driving and parking difficult. It feels unreliable and could cause a dangerous situation.
I was driving when I noticed my vehicle lagging and possibly misfiring, and then the "service four-wheel-drive" warning appeared. I was just down the road from my house, so I pulled into the driveway and put the car in park, but it wouldn’t turn off. I realized the parking brake was engaged and wouldn’t release either. I was stuck in two-wheel drive and couldn’t switch to four-wheel drive, and the emergency brake wouldn't disengage when I pressed the button, so the vehicle still wouldn't shut off. I had to put it in reverse physically step on the gas, which is the only way the parking brake finally disengaged and allowed the vehicle to shut off.
2025 chevy Tahoe: while approaching a traffic stop I hit the brake pedal and this would not work nor stopped the car. The pedal went all the way to the floor and would not work anymore. I believe the emergency brake activated and managed to stop the car. I was driving at the check engine warning light was immediately activated along with the following warnings: *service brake assist *check trailer brake lamps *service steering column lock *service traction control *service esc *service brake pad monitor *trailer brake disabled service required.
While I was driving, my vehicle suddenly lost all power I encountered a misfire with the engine light flashing, and diagnostic codes p0353 and p0300 indicated a misfire on cylinder three. The coil pack and spark plugs for that cylinder were replaced, yet issues persist and problems continue. There is a strange popping and cracking noise coming from my dash. My brakes are also making it loud sound randomly when pressing on breaks yet brake pads are fine.
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.
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.
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.
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.
