The infotainment system started taking ghost inputs. We replaced the screen and the ghost inputs are still there. The Human interface module has gone bad. There are many reports of this happening to chevys of similar years. Chevy dealership told me we need to replace the whole system for over $1200. I first started having this problem in 2024. It changes radio stations, moves the display screen, and tries to activate other buttons on the screen. Has also tried to call onstar.

when applying the brakes and come to a complete stop and when you try to apply the brakes you have no power assist and when backing up if you apply the brakes more then once you have no power assist.

The contact owns a 2017 Chevrolet Suburban. The contact stated that while driving at an undisclosed speed, the vehicle suddenly came to a complete stop. There was no warning light illuminated. The contact attempted to accelerate, and the vehicle drove sluggishly as if the tires were flat. The vehicle was taken to the dealer where it was diagnosed with transmission failure. The contact was informed that the transmission and motor mounts needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 125,000.

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.

On [XXX], our car was parked for 5 hours at a public marina. [XXX], Miami, Fl 33138. At 316 pm the MIami Dade Fire Rescue arrived promptly to put out the car fire. There is a fire station on scene. It seems to have started at center console. We serviced the car 1/19/2026, a thermostat in the engine. The engine was not the source of the fire. We also recieved a "green" clean check list on the car except to check tire pressure monitor. This electrical fire started center console. We had a minor glitch with the radio and navigation system at times, the original system. However we had a green check list in January, 2026.

I was driving in [XXX] on 1604 and the car was driving fine and out of nowhere. The car started shaking while on the highway for about seven8 seconds and then I heard an explosion smoke and fire. I pulled to the side. The car was on fire. The whole car was on fire within a minute or two I always took care of the car. Don’t understand how that happened.

The contact owned a 2017 Chevrolet Suburban. The contact stated that while driving at 40 MPH, another vehicle crashed into the rear driver side of the vehicle, causing him to lose control of the vehicle, collided into the curb, and the two right side tires, both driver's and passenger tires, became blown and damaged. The contact mentioned that after colliding with the curb, he crashed into a tree, which caused the right passenger side rim to detach from the tire. The contact also mention from the impact the whole right passenger side of the completely crushed and was damaged. The contact stated that no air bags deployed in his vehicle. The contact stated that he sustained a concussion to the head from the driver side window, brushing of the right rib, and bruises on both left and right hands. Medical attention was required. The contact stated that a police report was filed. The vehicle was towed to City Towing. The manufacturer was notified of this failure, and they requested information from the contact regarding the accident. The approximate failure mileage was 90,000.

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.
