2025 CHEVROLET SILVERADO 2500 — Problems, Recalls & Safety Data

Engine started pouring fuel out in large quantities coating the entire chassis. I was lucky, I had planned to go fishing early but had boat issue. Had I gone early in the dark it would have been catastrophic. Large amounts of gas. Pouring out. I'm lucky, when moving the truck my wife noticed the fuel was leaving a trail down the road and started screaming. I immediately parked the vehicle and I am waiting on support to get to dealer. The fuel system is a known defect on 2025/2026 Silverado but not yet identified for this HD 2500 with same 6.6l engine. Entire cab is full of gas fumes. This was extremely scary.

My 2025 Chevrolet Silverado 2500HD LT (new vehicle, low mileage) has a persistent water intrusion/leak into the cab interior. Water appears at the top of the headliner/ceiling, specifically around the overhead console where the HomeLink garage door opener buttons and map lights are located. This occurs after rain events, heavy precipitation, and results in visible wetness, dripping, and staining on the headliner fabric in the front overhead area. The leak is repeatable under wet conditions. It strongly suggests entry through the roof-mounted shark fin antenna (OnStar/XM/GPS antenna) seal or possibly the windshield-to-roof junction, as water migrates forward along the headliner to the overhead console area. This is a known issue pattern in prior GM trucks (e.g., 2014–2019 models with TSBs for shark fin antenna leaks causing headliner/overhead console drips), though not yet documented as widespread on the 2025 HD models. I took the vehicle to an authorized Chevrolet dealer for diagnosis and repair under warranty. The dealer performed an inspection but stated they could not replicate the leak during their test and therefore declined to perform any repairs, noting “unable to duplicate” on the repair order. Despite the waterline in the headliner and explaining the conditions (e.g., after heavy rain), no further action was taken. The issue continues to recur.

Supposedly The oil cooler ended up failing causing oil to be pumped into the cooling system at 26000 miles 8 months after purchase. A low oil message popped up upon start up looked under the hood a noticed no oil on the dip stick and a coolant reservoir full of jet black oil (supposed to be a bright red) and a fluid level higher than the normally observed coolant level. Thankfully happened in my drive way. It could have left me stranded had the engine completely run out of oil/overheated etc. Had the coolant reservoir broke/cracked due to the extra pressure and added volume in the coolant system it would have leaked a coolant/oil mixture in the engine bay around hot components of the motor. (potential fire hazard in my opinion) thankfully was able to get it towed to the dealer before any major leaks of the coolant system or catastrophic damage (that I know of) occurred.

I purchased my 2025 Chevrolet Silverado 2500HD new from Wilsonville Chevrolet in Oregon. Since owning the vehicle, I have experienced a noticeable shutter/vibration at highway speeds, consistently between 70–75 mph, whether towing or not. The shutter feels like it is coming from the transmission or driveline, and it occurs on multiple road types and conditions. I reported this issue to Wilsonville Chevrolet, but they told me they “could not duplicate” the problem and offered no repair. I then took the truck to Power Chevrolet in Corvallis, who stated the tires were out of balance and replaced them. This did not resolve the issue, and the shutter at highway speed remains exactly the same. I also contacted GM directly, but was redirected back to the dealership, resulting in no progress. At this point the issue has been reported multiple times, yet no root cause or repair has been provided. I am essentially being sent in circles without a solution. There appears to be a growing history of transmission-related issues with newer Chevrolet HD trucks equipped with the Allison 10-speed transmission, and this symptom seems consistent with those reports. A shutter at sustained highway speeds raises a significant safety concern, as a transmission failure at 70+ mph could lead to loss of control or power. In addition to the shutter, I have repeatedly noticed a strong “burning brake pad” smell coming from the rear of the truck. This happens randomly and has also been reported to the dealership, but no cause has been identified. I am unsure whether this is related to the transmission issue, but combined, these symptoms suggest a potential mechanical defect. Given the safety implications and the lack of resolution from authorized dealerships, I am requesting NHTSA’s assistance in investigating this issue.
