Interior Electrical System / Center Console Wireless Charging Pad The plastic housing surrounding the factory wireless phone charging pad in the center console has visibly melted and deformed. The damage is localized to the area directly above/around the induction charging coil, with no similar heat damage to adjacent console plastics, indicating the wireless charging module itself is the heat source. I stopped using this charging location upon noticing the deformation. This appears to be a component overheating defect that poses a potential fire risk if left in continued use. I am not aware of an existing recall or technical service bulletin covering physical melting of this component (existing GM bulletins address intermittent charging function only, not heat damage to plastic). Requesting this be documented and investigated.

What component or system failed or malfunctioned, and is it available for inspection upon request? The engine/powertrain failed. The vehicle is a 2025 GMC Sierra 1500 equipped with the 6.2L V8 engine. The engine developed a severe knocking noise and loss of power at approximately 5,545 miles. The vehicle was taken to the GM dealership, where an engine replacement was approved. The failed engine/component may be available for inspection through the dealership or GM, depending on whether it has already been removed or returned to the manufacturer. How was your safety or the safety of others put at risk? The engine failure created a safety concern because the vehicle experienced reduced power/loss of propulsion while being operated. This could have put me and other drivers at risk because a sudden loss of engine power can make it difficult to safely maintain speed, merge, tow, or move the vehicle out of traffic. The issue occurred at very low mileage and without enough warning to prevent the failure. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The problem was confirmed by a GM dealership. The dealer diagnosed the engine failure and GM approved an engine replacement under warranty. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle was inspected by the GM dealership. GM was involved in approving the engine replacement under warranty. To my knowledge, the vehicle has not been inspected by police 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? Prior to the failure, the vehicle developed a severe engine knocking noise and reduced power/lack of power. These symptoms appeared shortly before the engine failure at approximately 5,545 miles. I do not recall any specific warning lamps or messages before the failure, unless the dealership records

While driving at highway speed, my 2025 GMC Sierra suddenly began slowing down without warning and lost propulsion. When I pressed the accelerator, there was no acceleration response. The vehicle felt like it was braking or dragging instead of accelerating, creating a serious crash risk in traffic. A warning message appeared instructing me to “Put in neutral and restart truck.” I followed the instruction, but the vehicle would not restart. It sounded like it was attempting to start, but it would not start normally. A “Service ESC” warning also appeared. The vehicle was towed by AAA to a GMC dealership and remains available for inspection. The dealership provided a diagnostic trouble code report showing active codes: C2A07 Engine Control Module Indicated Torque Signal Malfunction; U0101 Lost Communication with Transmission Control Module; U0131 Lost Communication with Power Steering Control Module; U0140 Lost Communication with Body Control Module; U0146 Lost Communication with Central Gateway Module; U160F Lost Communication with Brake System Control Module 1 on CAN Bus 1; U1611 Lost Communication with Engine Control Module on CAN Bus 2; and U3003 Battery Voltage Circuit Voltage Below Threshold. The vehicle had approximately 22,000 miles at the time of the incident. The failure has not been repaired at the time of this complaint. The concern appears to involve a safety-related electrical, propulsion, powertrain, ESC/brake, and module communication failure that caused sudden loss of propulsion, no acceleration response, warning messages, and a no-start condition.

Notice during startups and slow speeds engine making taping noises. After bringing my truck in for service I was told my sound was my lifters on the passenger side.

Rough idle started at 11,400 miles. Took to GMC dealer near me and had thrust bearing clearance measured. Measured .0054"(within spec). They released truck back to me. 19,400 mile oil change found large metal(non magnetic) slivers in the filter media. I cut filters to check for issues due to known issues with this engine(metal). I called gmc corporate, i was told to not drive the truck. I paid out of pocket for the tow 142 miles away. Dealer told me they checked thrust bearing and came in at .0055", no noises, and no check engine light. Idle is very rough on start up. GM corporate stated a service advisor will call. Never got a call. I have sent and displayed the evidence and offered to show oil filter contents to both dealer and corporaten both have not done anything about this safety issue. This is a SEVERE safety issue. Engine is highly likely to lock up and cause serious injury to both me, my family, and others on the road. Dealer has released truck back to me and my family with clean bill stating they didnt find anything wrong. They refused to see my documentation of metal slivers or the 3 rimg binder full of maintenance records. As of now i will be escalating this to higher up in GMC corporate. SEVERE safety risk for my family and everyone on the road. GMC dealers refusing to diagnose.
