ENGINE, POWER TRAIN
We have a 2021 Chevy. Tahoe, and we just had an inspection done because a light kept coming on saying that our engine might fail. The shop initially said it needed cam shaft replacement, but now are saying the entire engine needs to be replaced. The care has ~ 67,000 miles on it and is 5 years old.

ENGINE
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 corporate subsequently mandated secondary diagnostic teardowns. Following these tests, GM confirmed a total, non-repairable engine failure requiring a complete engine assembly replacement. This vehicle has remained entirely out of service and non-operational since the date of the incident. On June 24, 2026, with the vehicle out of service for 36 consecutive days, I issued a formal demand letter to General Motors Customer Relations, demanding that they adhere to New York State Lemon Law statutory requirements and initiate an immediate vehicle buyback. Due to this severe defect, this vehicle is now deemed entirely unsafe and unreliable for my family, as our confidence in its mechanical integrity is permanently destroyed. Furthermore, a vehicle requiring a complete engine replacement at this mileage has suffered severe diminished financial value. A catastrophic engine failure on a low-mileage, current-generation vehicle poses an immediate, critical manufacturing defect and an unacceptable risk of high-speed collisions.

POWER TRAIN, VEHICLE SPEED CONTROL
Chevrolet has a recall on some vehicles for a bad transmission valve body, but my vehicle isn’t a part of the recall and I’m having the exact same issues. Currently my only vehicle that I have to transport my 7 month old is a complete safety risk. My check engine light is on and the code its throwing is to replace transmission valve body assembly. My Tahoe is shifting very harshly when driving normally, it feels like it slams into gears causing the whole car to jerk. When sitting at a red light that turns green, Tahoe is slipping, barely wanting to move through an intersection with vehicles all around me. I’ve been advised to not drive my Tahoe at all because if I do I will certainly have severe drivetrain damage and rear wheel lock up. Like I said, Chevrolet already has a recall for this issue on some of their vehicles, but my specific Tahoe does not. This is my only vehicle for myself and my baby and I cannot drive it due to its safety issues.

VISIBILITY/WIPER
Following a GM-initiated over-the-air (OTA) software update on May 18, 2026, my vehicle's windshield wipers became permanently inoperable — stuck in the "on" position with no ability to turn them off. This is not a gradual mechanical failure or wear-and-tear issue. The malfunction began immediately and directly as a result of a software update pushed by General Motors. Because the wipers cannot be controlled, I have been forced to remove the wiper fuse to make the vehicle driveable. This means I am currently operating a vehicle without functional windshield wipers — a federally mandated safety system. I want to be clear: this unsafe condition was caused entirely by a GM software update, not by any action or negligence on my part.

POWER TRAIN, ENGINE, VEHICLE SPEED CONTROL
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 intermittent and does not occur every time I accelerate, making it difficult to predict when it will happen. This condition creates a safety concern because sudden, unexpected increases in engine RPM while attempting to accelerate can affect vehicle performance and driver confidence, particularly when passing other vehicles or merging into traffic. The vehicle is being returned to the dealership for evaluation, and the defect remains unresolved.

ELECTRICAL SYSTEM
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 increase the risk of heat-related illness. Yes. An authorized Chevrolet dealership diagnosed the issue and replaced the condenser on June 5, 2026. The problem reoccurred within approximately one week of that repair. The vehicle has been inspected by an authorized Chevrolet dealership and remains available for inspection by the manufacturer or its representatives. There were no warning lights or messages. The only symptom was the air conditioning blowing hot air instead of cold air.

POWER TRAIN
My 2017 Chevrolet Tahoe equipped with a 6L80 transmission began experiencing transmission-related drivability issues at approximately 130,000 miles. The vehicle jerked on takeoff, had delayed/slow shifting, produced a whining noise, and later had intermittent shuddering/surging while driving. During service, metallic debris/shavings were found in the transmission fluid. The transmission ultimately required replacement at my expense. I am aware of GM Technical Service Bulletin 20-NA-142, “Shudder/Surging While Driving,” which includes 2015–2022 Chevrolet Tahoe models equipped with MYC/MYD transmissions and discusses conditions that may be identified as torque converter shudder. My vehicle’s 6L80 transmission corresponds with GM RPO MYC, and the symptoms/repair findings appeared consistent with the bulletin. I am filing this complaint to document the transmission failure and related safety concern, as the jerking, delayed shifting, and shuddering affected normal vehicle operation.

UNKNOWN OR OTHER
The rear AC evaporator located behind the paneling in the rear of the vehicle was leaking AC freon r-1234yf. This was diagnosed after a weeks long troubleshooting by my mechanic trying to find the leak in the rear AC lines causing the vehicle to fail the vacuum test. After he showed me the part and where the cracks were, he suggested I report this as a safety issue since the coolant was leaking inside the car and is highly flammable. He also said he has had many other GM vehicles with the same issue and thought a recall should be issued.

My vehicle would not shift into reverse. Took it into the Chevrolet service and they said the Valve body needs replaced. There are known issues with the Valve body in 2021 Tahoe but they said it is not covered under any of the GM extended warranties. It should be covered under Special Coverage N242454441 or N242454440, but they said no coverage. The vehicle only has 46,200 miles on it

ENGINE
While driving my 2021 Chevrolet Tahoe, the check engine light illuminated. Shortly thereafter, the engine began shaking severely and I heard clicking and popping noises from the engine compartment. The following morning, the vehicle was barely operable, shaking excessively and unable to properly reverse. Due to the unsafe condition, I had the vehicle towed to the dealership. The dealership diagnosed a failure involving all 8 lifters on one side (bank) of the engine, requiring extensive engine repairs. My vehicle has approximately 74,000 miles, which I believe is low mileage for such a significant internal engine failure. The symptoms included severe engine vibration, misfiring, loss of performance, and the potential for loss of power while driving. This is not the first major failure I have experienced with this vehicle. In approximately April 2023, when the vehicle had about 32,000 miles, it unexpectedly shut off while I was reversing in a roadway. The dealership diagnosed a failed fuel pump control module (fuel pump modulator). Similar failures were later identified in recalls and corrective actions affecting other GM vehicles. I am concerned that my vehicle has experienced multiple failures involving components that appear to be associated with known issues affecting GM vehicles, yet my Tahoe was not included in applicable recalls. These failures created significant safety concerns, including unexpected engine shutdown, loss of vehicle operation, and potential loss of power while driving. I respectfully request that NHTSA investigate whether my 2021 Chevrolet Tahoe vehicles should have been included in existing and future safety recalls related to these defects and other known defects that GM vehicles are experiencing with the motor, transmission and other parts. Note: No invoice is available yet as I am seeking GM assistance due to no warranty status. Estimated repair cost from dealership is up to $8,900.

I recieved this message after bringing my 2019 Chevy Tahoe to the dealership today for regular maintenanceand to check out a slight noise coming from under my hood: Rotational noise in your engine compartment had to remove the belts to be able to isolate where the sound was coming from. The noise is coming from the camshaft inside your engine so we know that is going bad. He also noticed that the engine mounts are worn out, oil cooler lines leaks and water pump leaking. I have kept up all required/recommended maintenance on time and didnt have any reason to believe I needed anything more then belts replaced and fluids changed when I took my truck to the dealer. After recieving that message, I spoke with the manager at the dealer and he said its a common issue. I've loved on my vehicle and value it as it is my only vehicle that transports my 2 children and myself around. Therefore im confused how this could happen outside of a manufacturer defect. There werent any warning lights, just a slight chirp coming from under the hood which sound like maybe a belt was going. The truck is at Boniface Chevy Melbourne Florida where I purchased it from.
