2025 Chevrolet Tahoe owner complaints

I was driving up to a border check point and slowed down at the guard shack. Once cleared I released the brake and tried to accelerate. The vehicle shut down completely. I tried to restart it and the check transmission warning came on. The vehicle would not restart. I was blocking the lane at the border check. After a few minutes I was able to start the vehicle and limp over to the shoulder of the freeway. There was no power and loud knocking and squealing from the engine compartment. Engine light came on and several other warning lights that I don't recall. I was in the desert with 3 dogs in an unsafe area for 7 hours until I could get help. Vehicle was towed to the dealership and is currently under diagnosis but so far code P0016 and metal pieces in the oil.

On May 19, 2026, my 2025 Chevrolet Tahoe suffered a sudden, catastrophic engine failure while traveling at 60 mph on a public roadway. I originally took retail delivery of this vehicle brand new on October 29, 2025, with only 14 miles on the odometer; at the time of the failure, the vehicle had only accumulated 10,049 total miles. The failure resulted in an immediate, complete loss of motive power at highway speeds, creating a severe, life-threatening safety hazard to myself, my passenger, and surrounding traffic. The vehicle was towed to an authorized GM dealership for emergency service. Upon removing the oil pan, dealership technicians discovered a high volume of metal debris and fragments, indicating a severe internal mechanical failure (likely failed engine bearings). General Motors c

I was leaving my neighborhood on Saturday night 5/16 around 5:30 and on the way out all of a sudden the dashboard started lighting up and the speed was dropping despite me being on the gas. The screens kept flashing then the car stopped and went into park and I could not get it out of park. I was at the front of my nieghborhood entrance and it made it hard for others to come in and out. I tried to restart it. My husband tried to jump it. I tow truck came about two hours later only to realize it could not tow it since the vehicle was stuck in park and could not be powered to move it to neutral. They had to call a new tow truck. I was sitting in my car stuck in the entrance of my neighborhood impeding traffic for close to 4.5 hours. A new tow truck finally arrived at close to 9:45pm.

4/24 The check engine light was flashing and the car went into limp mode and the display noted to pull over for safety. On 4/25 We took the car to the dealer they did some reprogramming. On 4/26 the vehicle keeps loosing power when driving.. Scheduled another appointment on 4/28 to have vehicle looked at.

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

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.

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).

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 aga

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

My 2025 Chevrolet Tahoe Z71 3.0L LZO Duramax with approx. 3,380 miles experienced a sudden and complete engine failure while towing my camper on the interstate at night, in the rain, while traveling alone 375 miles from home. The vehicle lost power, displayed warnings, and became inoperable, forcing me onto the shoulder in unsafe conditions. The engine has been diagnosed as requiring full replacement due to a defective crank end play / thrust bearing, under Technical Service Bulletin (TSB) 25-NA-307. This is a significant safety concern for a new vehicle and could have caused a crash. GM has multiple documented issues with this model year, and the car has also experienced unresolved infotainment defects, as outlined in TSB #PIT6393F. Requesting NHTSA to investigate a potential safety defe

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.

The air conditioning/climate control system failed. I initially brought the vehicle to the dealership on June 4, 2026, because it was blowing hot air. The dealership replaced the condenser on June 5, 2026. On June 12, 2026, the driver's side again began blowing hot air while the passenger side remained cold. By June 13, 2026, both sides were blowing hot air. The vehicle is being returned to the dealership on June 15, 2026, for an additional repair attempt related to the recurring air conditioning failure. The excessive heat created a safety concern because the cabin temperature exceeded 100°F despite the air conditioning being turned on. I developed hives and a rash on my face, neck, trunk, and arms from the heat exposure. Excessive cabin temperatures can impair driver concentration and i

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

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.

As i was driving down the road at approximately 40-45mph the sunroof spontaneously exploded. Sounded like a shotgun going off. Fortunately i had the sun shade shut but still tiny glass shards came in and fell on my child and the entire interior in the mid section of vehicle. There was no vehicle in front of me, it was night time with temps in mid 70’s no reason it should've exploded outward as if a gun shot from inside of vehicle which also implies nothing hit glass. Vehicle is at mcconnel automotive dealership where they are telling us that warranty will not cover this and we must claim on our insurance. I also called GM headquarters and they denied claim as well (case# 95312600) have spoke with several other owners on a facebook group this has happened to and GM has and is denying warran

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 caus

On June 12, 2026, while operating my 2025 Chevrolet Tahoe, I experienced an apparent powertrain or transmission-related issue. At the time, the vehicle was already exhibiting another defect involving the air conditioning system, with the driver's side blowing hot air and the passenger side blowing cold air. While attempting to accelerate and pass another vehicle, the engine RPM suddenly increased to approximately 6,000 RPM. The RPM remained elevated momentarily before gradually decreasing. The vehicle's response was abnormal and inconsistent with normal acceleration. Because I was close to home, I continued driving but remained concerned about the vehicle's operation. Since that incident, the same condition has occurred approximately two to three additional times. The problem is intermit

***SAFETY/DANGER*** On April 12th at around 5:30 p.m. my family of five, to include three minor children were returning home from visiting family which live about an hour and a half away and as we're traveling on the freeway at highway speeds, in traffic, our new Tahoe unexpectedly and without warning went into reduced power mode and cut speed down to approximately 35 MPH in active traffic, which out my family and every other car around me in danger and in jeopardy of causing a collision and even worse, a multiple car pile-up as I dodged full speed traffic in front and behind me while traveling at approximately half their speed. I managed to exit the freeway and heard a loud knocking noise from the engine and saw the reduced power mode indicator, all of which had not happened before but a

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 s
