2025 CHEVROLET TAHOE Complaints

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.

Vehicle power loss, some shaking with no warning lights on dashboard. Dealer confirmed it was engine failure.

I backed out of my driveway put it in drive stepped on the gas and the car hesitated and just shut down. Steering wheel locked up I had no time to even stair it out of the road. Try to start it and would not start but the dash and radio would come on. Tried to get in neutral to get it out of the road but everything is electronic so we could not do it. We had to have the car towed to the closet dealership. It took them two weeks to even diagnose the problem working along side GM service. Two weeks could have been saved with GM knowing they had a bulleting and problem with the LZO 3.0 Duramax diesel motors. It is not week 5 I still do not have a car and they have not even started putting the new motor in. GM has not been helpful AT ALL! It has been a miserable 5 weeks. They told me I could rent a car myself with a cap of $44 per day with all taxes and fees included and I MAY be reimbursed. So I have to put the money out of my pocket first and they may reimburse me. At this point I would be already out $1540.00 which is not in my budget. I purchased a brank new 2025 Chevy Tahoe 3.0 Duramax diesel motor car and it only has 8k miles on it and the motor is blown. I also paid for the car in full. I have asked GM numerous times to tell me where I went wrong and they have no answers as usual. It has been a horrible experience to this point and I have no idea when it is going to end. The dealership is trying to tell me that my car would not have dies going at higher speeds. I am so luck it happened in my neighborhood and not while on the highway. I could have been killed!

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.

Pulled into a pharmacy, vehicle died and completely shut off while driving. 3400 miles, towed to dealership, March 5, 2026. Still no answer from dealership for why this happened and no loaner vehicle yet because they cannot confirm it's a warranty issue

While driving on the highway, the vehicle suddenly downshifted and shut down and would not restart. All lights appeared on the cluster and showed "conditions not correct for shift". Had to have vehicle towed from the side of the road and wasn't even able to shift into neutral.

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.

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
