2025 Chevrolet Tahoe Problems

On September 5, 2026, at approximately 7:18 p.m. Pacific Time, a 2025 Chevrolet Tahoe High Country equipped with the 6.2L L87 V8 engine and approximately 18,000 miles experienced a sudden catastrophic failure while the engine was running. There were two occupants. A distinct pop was heard. The engine immediately lost power and multiple dashboard warning lights/messages began flashing. Within approximately 20-30 seconds, smoke and an electrical-burning odor were noticed. The vehicle was shut off manually and both occupants exited. Flames were first observed toward the rear of the engine compartment. The fire spread extremely rapidly, and the vehicle was substantially engulfed within approximately two minutes and completely destroyed. The sudden loss of propulsion created a crash risk, and the rapid fire placed both occupants at risk of serious injury or death. No physical injuries were reported. The precise failed component and fire origin have not yet been determined. The vehicle had received an oil change from an independent service facility within approximately 30 days before the incident. The cause has not been confirmed by GM, a dealer, or an independent fire expert. The vehicle is involved in an active insurance total-loss claim; inspection should be coordinated promptly before the salvage is released, dismantled, sold, or destroyed. More than 100 photographs and several videos taken during and after the fire are available. A fire department report is pending. Because NHTSA Engineering Analysis EA26005 includes 2021-2026 GM vehicles equipped with the L87 engine and later-produced engines outside Recall 25V-274, please associate this complaint with that investigation and evaluate whether an L87 engine failure initiated the fire.

Engine seized up and needs replacement.

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

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.

An Over-The-Air / Chevrolet Dealership software update removed a physical, hands-on-wheel control function, forcing me to divert my eyes from the road to the central touchscreen to perform a basic driving task (channel surfing) on the radio. Specifically, the right front steering wheel toggle used to allow you to scroll sequentially up or down from one radio station / frequency / SiriusXM channel to the next. The new functionality only allows you to select preset stations, duplicating the functionality on the left rear (back side of the wheel) steering wheel toggle button. The only way you can now scroll sequentially up/down from one channel to the next is by taking your eyes off the road, reaching over to the center console, and swiping left or right to move from one channel to the next. This is far more dangerous as it is a distraction to the driver and it takes the driver's eyes off their forward view.

This 2025 Chevrolet Tahoe has experienced three separate and recurring engine-related failures. The first failure occurred at approximately 41,350 miles and required replacement or repair of the lifters and camshaft. The vehicle remained at the dealership for approximately 15 days. The second failure occurred at approximately 54,619 miles and involved another lifter failure along with traction control problems. The third failure occurred at approximately 65,140 miles. The Check Engine warning light illuminated while the vehicle was being driven, and the vehicle again experienced engine-related problems. The vehicle has now been at the dealership for more than one week, and no repair or permanent solution has been provided. I am concerned that these repeated engine failures and traction control problems create a serious safety risk, particularly because the vehicle is driven on public roads and highways. Despite previous repairs, the engine problems continue to recur. I am requesting that NHTSA investigate these repeated safety-related failures.

ON JUNE 2ND 2026, the air conditioning in my 2025 Chevrolet Tahoe failed without warning. The system began blowing warm air instead of cold air, making the vehicle uncomfortable to drive. At the same time, I noticed that both front ventilated (cooled) seats had also stopped working. Although the seat cooling indicator lights illuminated when activated, the seats did not produce any cooling. I called to schedule an appt and took the vehicle to the dealership for diagnosis and repair on june 4, 2026. The dealership determined that the A/C condenser had failed and replaced it. I was advised that the repair had been completed, and I picked up the vehicle believing the issue had been resolved. Shortly after the repair, it became apparent that the problems had not been fully corrected. While the air conditioning initially appeared to function, the ventilated seats continued to provide no cooling despite appearing to operate normally. This marked the beginning of an ongoing series of HVAC-related failures that ultimately required multiple return visits to the dealership.

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

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.

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.

On Friday May 1, 2026 while parked at my home, the rear glass lift gate burst into multiple shards. I have taken a few photos of the outside as I found it. In my surprise, I failed to photograph the glass in the interior of the vehicle. I have owned this car since new, since near the end of July of 2025. I had unloaded some groceries from the back area, raising and lowering the large metal lift gate. The glass lift gate was NOT used. As a matter of recording, I have only lifted the glass once or twice since owning the vehicle. The main metal lift gate is the unit used most often. Apparently, this is a known issue with several reports online. What I found online seems similar in that no impact or accident occurred to cause the glass to shatter. What is odd, instead of a typical safety glass experience of a "spider web" type of fracture and the glass staying intact, this was "exploded" with the glass found in multiple shards both in the car and outside on the ground. When I called my local Chevrolet dealer, they denied knowledge of this as a problem within the fleet. Because this is a use issue and weather issue, I am having to personally pay for repair. The new window will cost almost $1000.00 to repair.
