2025 Chevrolet Tahoe

My Vehicle has a 5,3 engine it now has 23000 miles. It goes to the dealership for all the oil changes. I check my dipstick before I took it in for service and warranty work for a third time first time at this dealership. But noticed there was no oil on the dipstick. So I went to auto zone and bought a new 3 gallon container and funnel. So they changed my oil and put it in and I got my vehicle back and I now bought a clear 2 gallon measuring bucket to see how much oil I had in it. I just videod my pour into the container and it is 3 quarts low. I was under the 7500-mile mark that gm requires you to change the oil. This is a new vehicle, and I shouldn't see this happening at all maybe 100000 miles but not 23000. I also just found out I have a one of a kind 2025 Tahoe with the new 2026 software that is completely messed up. The dealership wiped out critical engine data and no that is at zero when I picked it up. And the calculation for engine hours and idle is not the true numbers and it is corrupted. The other dealership didn't know my vehicle has the new data. So I can only assume they made a big mistake releasing this vehicle. So I also have a driver's seat that goes snap or clunk. Everything with GM has Bulletins. I didn't buy a 86000 dollar used piece of junk i bought a brand-new truck. And Gm will not let the dealership tear into the engine to find out what the noise is and the damage. I use a stethoscope and you can hear the lifters and rockers on the left bank, and the front makes strange noises and it has a hollow sound also. So sensor collision avoidance issues since the day I bought it. And with all the corrupt downloads from whatever software they used has destroyed my Tahoe along with the engine. I have video evidence also and the oil that just came out of my vehicle was gross dark and disgusting and smelled to high heaven. I need help

Driving in bumper to bumper traffic in my 2025 Tahoe and the automatic braking system slammed on the brakes at 10 mph causing me to get rear ended.The light turned green and traffic started moving forward and I'm hitting the gas pedal when my truck just slams on the brakes causing the girl behind to rear end me. The car in front of me was moving forward and never hit their brakes but my car still slammed on the brakes for no reason. I was probably 6 or 7 feet away from the car in front. This isn't the first time this car has slammed on the brakes for no reason. It always seems to happen in the summer during sunny mornings as I'm headed east driving towards the sun. I got lucky the other 6 or 7 times this has happened up until today

The issue is related to Super Cruise hands free driving. During a recent long trip multiple times the Super Cruise signaled for lane change and tried to move into the passing lane with a car directly beside me. I have 8,500 miles on this car and have used Super Cruise extensively on highway driving only and until this last trip never had any issue with the system seeing cars in lanes beside me before. I only avoided a collision because I prevented the lane change by grabbing the steering wheel. This software bug will end up with injury or death of individuals unless Chevy fixes this immediately. Your help in investigating this is appreciated. I will add my son has a 2025 Suburban and has experienced the car trying to pull into traffic beside him.

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.

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

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.
