2025 CHEVROLET TAHOE Complaints

On approximately January 15, 2026, my 2025 Chevrolet Tahoe equipped with the 6.2L V8 engine suffered a complete engine failure at approximately 10,000 miles while my family and I were traveling about six hours from home. The engine/propulsion system failed and the vehicle became inoperable. The specific internal engine component that initially failed is UNKNOWN. The sudden failure put my family at risk because we were stranded far from home with an inoperable vehicle. The Tahoe had to be taken to an authorized Chevrolet dealership, where the engine failure was confirmed and warranty repairs were performed. General Motors opened Chevrolet Customer Assistance case number 87586632 on January 16, 2026 and communicated with the dealership throughout the repair. The Tahoe remained at the dealership awaiting repairs and parts through at least February 4, 2026. GM correspondence confirms that the vehicle had been returned to us by February 7, 2026. The vehicle was unavailable for approximately three weeks. Prior to the failure, OnStar sent a low 12-volt battery alert on January 15, 2026. I do not know whether that alert was related to the engine failure. On February 2, 2026, while the vehicle was still undergoing repairs, OnStar sent a critical engine and transmission system diagnostic alert. Any other warning lamps, messages, noises, or symptoms immediately preceding the failure are UNKNOWN. The vehicle was inspected and repaired by an authorized Chevrolet dealership, and General Motors was involved through its Customer Assistance department. Whether a GM representative separately inspected the failed engine is UNKNOWN. The vehicle was not inspected by police or an insurance representative to my knowledge. Whether the original failed engine or its components are still available for inspection is UNKNOWN; the dealership or General Motors may have retained them. 2025 Chevrolet Tahoe, case number 87586632.

2025 Chevrolet Tahoe, 6.2L L87, approximately 51,500 miles, rod-bearing/internal engine failure, complete engine replacement required. 1500 miles prior to engine failure the cam/lifters were replaced. Repair invoices are attached. I was told my warranty going forward would be the remaining miles left on my 60k power train warranty. This is not acceptable.

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

I have 19,000 miles. After each oil change, the engine begins to idol rough, the vehicle violently shakes and the traction control and ABS turn off. The first time this happened it was determined that there was a cylinder (4) failure causing a missfire. This was corrected under warranty. A few months later immediately after receiving an oil change again, the same actions occurred. This time the computer is showing a cylinder (7) failure and engine missfire. This is very similar to what is happening on the 6.7 L GM recall l, but I don’t have the 6.7 I have the 5.8. I believe the issue is bigger than just the 6.7 L.

Was driving and without warning the engine locked up. Went into a coast to a stop and motor locked up.

A GM software update removed the ability to seek radio stations using the steering-wheel controls, forcing me to use the center infotainment screen for a routine task that previously could be done without looking away from the road. Since this change, I have experienced unintended lane deviation while trying to change stations. I reported the issue to GM, but they only documented the complaint and provided no corrective action. I am asking NHTSA to evaluate whether this software change creates an unreasonable driver-distraction safety risk.

Was driving to dinner with my wife and 2 kids and we heard a loud sound like a shot gun went off. After pulling into a parking lot we a hole in the moon roof and the glass push outward like it exploded.

My 2025 Chevrolet Tahoe RST Performance Edition equipped with the 6.2-liter V8 experienced a catastrophic engine failure at approximately 28,400 miles. The Tahoe was towed to an authorized Chevrolet dealership. The dealer confirmed an internal engine failure requiring complete engine replacement. The vehicle and failed engine are currently at the dealership in Lawrence, Kansas, and should be available for inspection upon request. The precise internal cause has not yet been provided to me in writing. I was advised that obtaining and installing the replacement engine is expected to take approximately 60 to 90 days or longer. The scheduled 30,000-mile maintenance was performed by the Chevrolet dealership on June 29, 2026, when the odometer read 27,607 miles. The engine failed less than two weeks later, after approximately 800 additional miles. Two days before the failure, I noticed a knocking or ticking sound from the engine. Immediately before the failure, I heard loud squeaking or screeching followed by a severe metallic clanking sound, as though loose metal components were being thrown around inside the engine. The engine then shut off and the vehicle became immobilized in Park at an intersection. I was the first vehicle in a left-turn lane and could not shift the Tahoe into Neutral to push or coast it out of the roadway. Heavy traffic turning toward the highway was forced to maneuver around the disabled vehicle, creating a significant risk of a collision. The outside temperature was approximately 95 degrees, with a heat index of approximately 109 degrees. My dog was with me, and it took more than an hour to arrange transportation for him to a safe location before I could return to the disabled vehicle and continue waiting for the tow truck.

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.
