2025 CHEVROLET SILVERADO 2500 Complaints

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.

Following vehicle startup, the entire audio system defaults to a muted state, affecting all sound output channels. This includes, but is not limited to: ?Critical Safety Alerts: Seat belt warnings, system malfunction indicators, and door ajar chimes. ?Proximity and Collision Warnings: Parking assist chimes, Rear Cross-Traffic Alert (RCTA) warnings, and Backup Collision Intervention (BCI) alerts. ?Communication Systems: Navigation prompts and hands-free/Bluetooth call audio. ?The audio failure persists until manual user intervention or the next vehicle cycle, disabling critical warning redundancy. ?Safety Implications ?The system-wide audio failure directly compromises the safety of vehicle occupants and surrounding pedestrians in two primary ways: ?Risk to Pedestrians: The silencing of proximity and backup collision warnings (RCTA, BCI) removes a vital layer of redundancy, significantly increasing the risk of striking vulnerable road users, such as children, while maneuvering in reverse. ?Impaired Driver Safety & Compliance: The defect also removes essential alerts like seat belt warnings and renders the mandated hands-free communication system inoperable, forcing potential driver distraction or non-compliance with driving regulations. ?Conclusion ?This audio muting defect is a critical safety failure that disables mandated auditory warning systems, severely limiting the driver's ability to operate the vehicle safely and respond to immediate, unseen hazards. Immediate investigation and resolution are necessary.

I do not have access to my owners manual. One was not included with the truck when I bought it. I was told I could download it in the app, but I am still unable to do so.

Tailgate has been coming open while driving. Multiple times. The last time it landed on the jack of my enclosed trailer. Without me knowing. First time was 2-3-25 and the last time was 9-2-25

When towing a trailer, the trailer brakes will disconnect when applying medium to hard brake. This is when the brakes on the trailer are needed the most. The trailer lights still work when the brakes controller disconnects them. There was a recall on the 2024 Chevrolet HD trucks to "fix" this.

The contact owns a 2025 Chevrolet Silverado 2500. The contact stated that while driving 75 MPH, the vehicle independently pulled to the left. The vehicle was taken to the dealer, and the contact was informed that an alignment was needed. The vehicle was repaired. The contact stated that due to the persistent failure, the vehicle was taken to the dealer six times. The contact stated that two times the failure was not duplicated. The contact stated that four alignments were performed, and the front driver's side tire was replaced. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 500.

The contact owns a 2025 Chevrolet Silverado 2500. The contact stated while her husband was hauling a trailer and driving 55 MPH in the snow, the vehicle lost power steering functionality. In addition, the contact stated the vehicle failed to accelerate as intended while depressing the accelerator pedal before slamming into gear. The RPM fluctuated up to 6,500 RPM. The contact stated that the check engine warning light was illuminated. The contact's husband was able to coast to the side of the road. The vehicle was turned off but failed to restart. The contact's husband stepped out of the vehicle, and the vehicle restarted automatically. The vehicle was towed to a dealer, where it was diagnosed that the wiring was for a diesel vehicle; however, the contact's vehicle was gasoline operated. The contact was informed that the wiring harness control arm had rubbed against the control arm, causing the electrical system to short-circuit. The vehicle was repaired. The failure had progressively gotten worse. Most recently, the contact stated that the vehicle vibrated abnormally while driving. The vehicle was taken to the dealer; however, no cause for the failure was found. The contact stated that a seal was placed on the transmission. The manufacturer was made aware of the failure but denied assistance. The failure mileage was approximately 42,000.

Have had issues since purchase of paint chipping severely / cloudy. Transmission shudder and “jumped forward” when coming to a stop. lighting system “blinked” or went dark and come back up a few seconds later while driving.
