Tahoe

The automatic transmission on my 2019 Chevrolet Tahoe has failed prematurely at approximately 88,000 miles. The dealership confirmed internal transmission damage, specifically that Solenoid #3 in the valve body is sticking and not engaging, which requires a complete transmission replacement. Their written inspection states: “Possible internal damage in transmission. Solenoid 3 in valve body is not engaging.” The component is available for inspection upon request. Safety Risk: This malfunction created several dangerous situations. The vehicle hesitated, struggled to shift into gear, and at times moved forward while in reverse. These symptoms could cause loss of control, delayed acceleration when entering traffic, or unexpected movement putting myself and others at risk. Diagnosis Confirmation: Yes. The problem has been fully inspected, reproduced, and confirmed by an authorized Chevrolet dealership service center. They provided a written estimate of 8,669.59 for a complete transmission replacement. Inspection by Others: The transmission has been inspected by the dealership where the vehicle was purchased. No independent mechanic, police, or insurance representative has inspected it yet, but the dealership’s findings are available. Warning Lamps or Symptoms: Prior to the failure, I experienced hesitation, difficulty engaging gears, harsh shifting, and the vehicle lunging forward while in reverse. Shortly after these symptoms appeared, both the check engine light and tire pressure light came on. Additional Context: GM has released multiple Technical Service Bulletins (TSBs), including 19-NA-153 and 21-NA-199, addressing known issues with their 8-speed transmissions such as harsh shifting, slipping, and valve body/solenoid problems. This suggests a broader pattern of defects. GM and the dealership offered only 10% goodwill assistance, leaving almost the entire repair cost to the consumer, despite this being an internal mechanical defect with normal personal use.

Hit a road sign at 45mph - airbags did not deploy.

Alignment and suspend has vehicle shaking,rumbling and shifts all over when hitting a bump in road. J.B.A. Chevrolet had detected alignment/suspension problem. Had check engine light come on but Carmax claimed it was a history code. The transmission had to be replaced. Still experiencing multiple problems with said vehicle.

When I get up to a certain speed the car begins to shake. Tires were checked for balance. My public records show a recall # N192261050. I have the Product Safety Recall and it describes this issue in the recall. I bought the car in 2023 and just began experiencing this in June of 2025. It only happens while driving 60-70mph. Have not have this fixed thinking it was a road issue but have had several more incidents with this happening and now it's a safety concern.

The contact owns a 2019 Chevrolet Tahoe. The contact stated that the vehicle was consuming an excessive amount of engine oil. While driving at 30 MPH, the vehicle stalled consistently while shifting gears. There were no warning lights illuminated. Upon investigation, the contact linked the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included in the recall. The vehicle was taken to three independent mechanic,s who indicated that the failure was related to the engine. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 120,000.

Loss of power

While driving on the expressway I heard a rattling noise coming from my undercarriage, by the time I got off my exit the sound got louder, I attempted to make it home and when I pulled in my driveway, and popped the hood, fluid starting pouring out the bottom as well as splashed on other components. Upon further inspection it was determined that the fluid was coolant. There was no dashboards lights or warning signs indicating that something was wrong or that my car was at risk of overheating. I had the vehicle towed to an auto repair shop and the following was diagnosed and repaired: •Water pump •Cooling System •Engine Water pump •Engine Coolant thermostat housing assembly. •Serpentine Belt

The contact owned a 2019 Chevrolet Tahoe. The contact stated that while driving on a winding road during a rainstorm at 15 MPH, she briefly lost control of the vehicle and left the roadway, coming to a complete stop after colliding with a tree. The impact of the collision was severe that the front passenger side wheel became detached. The air bags did not deploy. No warning lights were illuminated. The vehicle was towed to an independent mechanic, who had yet to determine why the air bags did not deploy, however, the contact was informed that the vehicle may be deemed a total loss by her insurance provider. A police report was not filed, but minor injuries were reported, which the contact attributed to the fact that the air bags did not deploy. The contact sustained a small bruise on her chin and a contusion across her chest, but did not seek medical treatment immediately following the accident. Surprisingly enough, the chest contusion had yet to heal 2 weeks after the injury was sustained. Alarmed, the contact consulted her primary care physician, who then scheduled an X-ray for a later date. The manufacturer was not notified of the failure. The failure mileage was unknown.
