I am writing to formally report a critical safety defect in the vehicle’s transmission system. While driving, the vehicle began experiencing severe vibrations, accompanied by an abnormal increase in engine RPMs, while the vehicle failed to accelerate appropriately. The vehicle became unresponsive, limiting my speed to 15-20 mph. This forced me to make frequent stops every 6-7 minutes to allow the transmission to cool down, as the car would not sustain normal speeds. ​This failure created an extremely dangerous situation on the highway. Due to the sudden loss of power and inability to maintain traffic flow, I was subjected to aggressive behavior from other drivers, who were honking, gesturing, and clearly endangered by my inability to accelerate. This transmission failure is a major safety hazard that renders the vehicle unreliable and dangerous to operate in any traffic condition. I am requesting an immediate investigation into this transmission defect and a permanent resolution from General Motors, as this issue poses a significant risk of causing a collision. I spoke with the owner of AAMCO, and he showed me that they have 7 of these Chevy Suburbans, GMC Yukons, and Chevy Tahoes, Escalades, and they all have the same problem, the transmission needs to be replaced, and General Motors is not notifying car owners about this problem, but it should.

What component or system failed or malfunctioned, and is it available for inspection upon request? The fuel delivery system has failed. Specifically, the fuel lines are leaking at the connection point on the top of the fuel tank. The vehicle and the affected components are currently available for inspection upon request. How was your safety or the safety of others put at risk? This defect poses an immediate fire and life-safety hazard. Because the fuel leaks while the vehicle is powered on, any spark or heat source could ignite the fuel tank, leading to a vehicle fire or explosion. Additionally, the cabin environment has become toxic; the concentration of gasoline vapors is so high that it causes physical illness. One of my children vomited due to the fumes. The vehicle is currently undrivable because the vapors are intoxicating and hazardous to the health of all occupants. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the leak has been inspected, reproduced, and confirmed by an independent service center. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, the vehicle has not yet been inspected by the manufacturer, law enforcement, or insurance representatives. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps or dashboard messages (such as a Check Engine Light) prior to or during the failure. The symptoms—specifically a strong odor of raw gasoline—first appeared four days ago. The intensity of the odor and the rate of the leak have increased significantly since the initial onset.

Component or System Failure The vehicle experienced two major mechanical failures. First, the transmission failed and required full replacement shortly after the expiration of the 60,000-mile powertrain warranty. At the time of this failure, the vehicle had approximately 61,000 miles. Second, at 100,119 miles, the engine suffered a catastrophic failure that required complete engine replacement. Safety Risk The transmission failure impaired normal drivability and created a safety risk due to reduced or unreliable propulsion, which could have resulted in loss of power while driving in traffic. The engine failure rendered the vehicle inoperable and could have posed a serious safety hazard if it had occurred while the vehicle was in motion, including sudden loss of engine power. Problem Confirmation and Inspection Both failures were diagnosed and confirmed by dealership service personnel, who determined that full replacement of the transmission and later the engine was necessary. The issues were identified through inspection and standard diagnostic procedures. Warning Lamps or Symptoms There were no clear, persistent, or meaningful warning lamps, messages, or symptoms that would have reasonably alerted the driver to an impending transmission failure prior to it occurring. Any warning indicators appeared at or immediately before the failure. Similarly, there were no significant warning signs that would have predicted the engine failure prior to the need for complete replacement. Additional Information Both the transmission and engine failed at relatively low mileage for major powertrain components. The transmission failure occurred just beyond the powertrain warranty threshold, and the engine required full replacement at 100,119 miles. . These failures suggest a potential defect or durability concern affecting critical powertrain systems.

While driving, the vehicle has repeatedly experienced sudden loss of power and electrical failures without warning. During these events, the dashboard flickers, warning messages appear, and the vehicle shuts off or goes into reduced power mode. When this occurs, steering becomes extremely difficult, braking becomes stiff, and the vehicle cannot accelerate. These incidents have happened multiple times in different driving situations, including: At stoplights While pulling into intersections Backing out of parking spaces Driving on public roads, including dark rural roads Driving with my three minor children in the vehicle On at least one occasion, the vehicle shut off while pulling onto a road with oncoming traffic, leaving us stopped in the roadway with no power and limited steering/braking. This created an immediate and serious risk of collision. The vehicle eventually restarted after several attempts. The problem has occurred repeatedly over many months. Multiple independent repair facilities have attempted to diagnose and repair the issue, but no definitive cause has been identified, and the failures continue. The vehicle has had numerous electrical, sensor, engine, and powertrain-related repairs, yet the loss-of-power events persist. Because the vehicle can suddenly shut down while in motion and compromise steering and braking, I believe this is a serious safety defect that could result in a crash, injury, or worse.

The passenger seat belt will no longer just click in. In order for us to get it to latch, you have to push down on the red button as your pushing the seat belt in, then it will latch. We bought this used and within 1-2 weeks this happened. But other things happened with the engine and that took priority. It was in the shop for almost 6 months. I'm not sure if the dealer/ previous seller knew about it and they were able to "fix" it so it worked when we bought it. (We are lied to on a lot of things) I'm afraid that it might not hold up in a crash if it's not buckling right.

I purchased this car at CarZone in Riverside This April 2024. I drove home with my kids in the dark and people kept honking. The lights and turn signals did not work. I took the car back in. The back up camera was broken, the safety system is broken, brakes are bad, they put two bald and all four tires with gummy plugs after I brought it back a fourth time. The tires were not fixed. I found out driving on the highway with my daughter. My tires popped. I had to pay for all four to be replaced and the dealership will not take any of my calls. I then had a check oil light. I took the car in. Pep boys discovered they had replaced the oil hose with a different one. It backed up into the engine. I paid for an oil change and was told to keep an eye on it and contact the dealership. They would not respond. I went back to pep boys be my car was completely out of oil one week later and my headlights kept dying and the car wont accelerate. They did another diagnostic and contacted the dealership and warranty saying it needs a new engine entirely. They sent an adjuster who said nothing was wrong and closed it. I have had to take the car back since. The liftgate is zip tied to the tail pipe. I am terrified to drive this car, especially the head light and brakes. I bought new tires bc the dealership would not help even though I have all the text messages they sent about the issues. It no longer accelerates the way it should and I have to put three quarts of oil minimum per week to keep it running at all. I am out so much money that I do not have and I cant drive an unsafe car with my babies in it. Upon further investigation I have found this dealership has done this to many people. I just need help getting them to take this car back or pay to fix it and to make sure they are following safety laws. I feel responsible to report this because I know I wish someone else had and it would be absolutely devastating if someone got injured in a vehicle sold by them.

6L80 transmission failure at only 82k miles. This is a known Chevrolet fail point on all vehicles equipped with this transmission yet Chevrolet does nothing to recall or repair the issue. Customer absorbs full cost of repair ($6k) and chevrolet acts like they know nothing about it. This happens on the highway at speeds and vehicles suddenly have no drive putting occupants at risk of other traffic and trying to get off the roadway where there may be no safe zone to stop.
