2025 CHEVROLET SILVERADO 1500

ELECTRICAL SYSTEM

The vehicle was a service loaner provided to me but it was factory new with the sticker still on the window. The dealer told me they would still sell the vehicle as new. When I started it, I had a display screen that indicated it was in a Demo mode. Taking it out of Demo mode would have required me to confirm that I had purchased the vehicle. The volume control and power control for the audio were not working at all. The volume was probably at 30% where I could hear but not clearly and also just loud enough that I couldn't hear sounds outside the vehicle well. This condition was not affected by the audio source. I could no change the volume in Bluetooth, AM, FM, XM, or Phone modes. I also could not turn off or mute the audio by pressing the Power button. There was a responding fire truck behind me on the road and I went to turn off the audio to hear it clearly and I was not able to. I took a video of this condition happening multiple times as photographs don't help to demonstrate much. I did notify the dealer by sending the Service Manager a text message with the video and said he would notate the condition. This persisted through multiple days and multiple restarts. After approx. 4-5 days, the expected functionality returned with no action or updates that I am aware of.

ENGINE

At 5,750 mi. the 6.2 gas engine seized due to connecting rod bearings. The dealer replaced the engine, cooling system and oil cooling system under warranty with a similar engine. I am of the opinion that it could have been at least partly due to the low viscosity motor oil that the manufacturer insists upon to maintain the factory warranty, 0-W20 synthetic, along with a poorly engineered fuel management system. Also, once the vehicle was stopped and put into park, the electronically controlled transmission refused to change gears, to be put into neutral, in order to be pushed out of traffic and on to a tow vehicle, it had to be dragged. The vehicle is extremely unreliable and a danger to the public.

VEHICLE SPEED CONTROL

On the evening of August 27, 25, when exiting the highway ramp, the vehicle's engine suddenly stopped and stalled, the gear automatically shifted to neutral, and the hazard lights could not be turned on. After about 2 minutes, it restarted normally and turned on the hazard lights.

ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL

The contact owns a 2025 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the instrument cluster displayed a black screen and seized. The contact stated that occasionally the instrument cluster failed to activate. The vehicle was taken to the dealer, where it was diagnosed with instrument cluster failure. The contact was informed that the instrument cluster needed to be replaced. The vehicle was not repaired. The contact was informed that the parts were not available to repair the instrument cluster. The contact referenced an undisclosed recall; however, the VIN was not under recall. The contact stated that the failure started immediately after the vehicle was purchased. The contact had been waiting for delivery of the parts for two months. The manufacturer was made aware of the failure, and a case was filed. The contact stated that the manufacturer had been contacted more than twenty times. The failure mileage was approximately 2.

POWER TRAIN

Transmission would not engage reverse gear. Then forward drive gears hard shift and surging. Truck delivered to dealer, inspection revealed a bad valve body. Parts availability unknown. No warning lights or caution lights. Just broke in a parking garage in Aspen Co. I live in south Texas. Truck and travel trailer in Colorado. Truck has 16000 miles. Had this failed two days before we would have been on pikes peak mountain. And the danger of transmission failure going up or down the mountain would have been very dangerous.

STEERING

My 2025 Chevy Silverado ZR2 has experienced the same dangerous system failure five times. While driving, every warning light on the dash activates, I lose power steering, and the vehicle completely shuts down and won’t restart. This creates an extreme safety risk — the first failure happened on a local road, but most recently, it occurred while my family was driving out of state during a holiday. The truck has now been out of service for over 50 cumulative days across these repeated incidents. GM has accepted a Lemon Law claim but has not resolved it, leaving me without a vehicle and no clear path forward. These systemic failures present serious risks to me, my family, and other drivers. The latest failure occurred in July 2025, and the vehicle remains at Bill Cramer Chevrolet in Panama City Beach, FL with no resolution. I am still making loan payments and paying for transportation out-of-pocket, without any support from the manufacturer.

POWER TRAIN

when coming to a stop, the truck idols high before slowly going down. Seems unsafe as if is not wanting to stop. I am also hearing a chirping coming from under the hood.

POWER TRAIN

My 2025 Certified Pre-owned, 10 day old truck with approx. 6200 miles, was parked and I was unable to shift into reverse (as if in neutral). I put the truck in drive and entered the highway. About half a mile later, multiple warning lights appeared and the truck slowed, unable to shift out of gear. Luckily, there was a dealership a few miles away so I drove the truck there slowly and on the shoulder as much as possible. Upon inspection at the dealership, they told me that the valve body needed to be replaced. After the repair, which only took a few days, the dealership was test-driving the truck when the powertrain completely seized. They attempted to restart the truck but burned out the starter and fuse block which was also replaced. After a GM engineer gave the mechanics permission, they dropped the transmission to find that it was completely seized and had also seized the engine, though the engine was reportedly not damaged. The entire transmission was replaced and the truck was returned to me with about a month of downtime. This was a clear safety issue as the truck stopped working while on a highway. Luckily, I was in a heavily populated area where help was available. The transmission was returned to GM for further inspection and the repair was fully covered under warranty. Prior to the incident, there were no warning lights/messages, but only appeared after the issue.

FUEL/PROPULSION SYSTEM

Issues with DEF system. Fuel and DEF tank is filled up. Within 100 miles of towing the DEF system states DEF is empty and Speed will be limited within 500 miles. At the time the message appears on screen, fuel mileage goes from 13ish mpg to 8 mpg. Try to add DEF and only able to add close to a gallon of DEF. System has a hard time recalculating the amount of DEF in system.

ELECTRICAL SYSTEM:IGNITION:ANTI-THEFT:IMMOBILIZER/PROXIMITY:KEY/SENDER

The contact owns a 2025 Chevrolet Silverado 1500. The contact stated while the vehicle was parked in the garage, the key fob was accidentally depressed twice. There were no warning light lights illuminated. The contact stated that the design of the key fob was different from the key fob for a similar vehicle the contact owned, just an older model. On the older model, whenever the contact pressed the key fob and the lock button was pressed, the vehicle would start. The contact stated that on the new vehicle, when the lock button was pressed twice the vehicle would start unintendedly while the vehicle was in the garage. The contact stated that on another occasion, the key fob was pressed twice unintendedly and the tailgate open, and the vehicle started. The contact believed the failure was caused by a defect. The vehicle was not taken to be diagnosed or repaired. The dealer was not made aware of the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 3,000.

ENGINE

The "Auto-stop" feature of the engine apparently automatically turns itself on every time the engine is started. there is no warning light or other indication that it is on except a very small light ON THE SWITCH TO SHUT OFF. The auto-stop function itself is inherently unsafe because it shuts the engine off and doesn't restart it until the operator removes his foot from the brake.... -sometimes it takes several seconds to restart. If you take your foot off from the pedal and then put it back on and the vehicle rolls back a bit, it may not start at all, necessitating shifting to park and manually restarting the engine. If it does start late, the engine may surge and the vehicle will lurch ahead into traffic. I have had two close calls because of the "auto-stop", once causing a semi-trailer truck to veer away to miss me. Any driver that fails to disengage the auto-stop function on engine start is putting his own and other peoples lives in danger. NO FEATURE AFFECTING ENGINE ON-OFF, VEHICLE SPEED, STEERING , OR BRAKING SHOULD EVER BE ENGAGED WITHOUT A SPECIFIC COMMAND BY THE OPERATOR OF THE VEHICLE. WHEN IT IS ENGAGED, BY THE OPERATOR, AN AMBER WARNING LIGHT SHOULD SHOW ON THE DASH PANEL AND STAY ON AS LONG AS THAT AUTOMATIC FEATURE IS ENGAGED. IF NOT, THE VEHICLE MANUFACTURER SHOULD BE HELD TOTALLY AND SOLELY RESPONSIBLE FOR ANY ACCIDENT THAT OCCURS AS A RESULT OF THAT FEATURE.

ELECTRICAL SYSTEM

Driving on road at approximately 30 mph. All lights on dash came on and car braked suddenly immediately stopping the vehicle in the middle of traffic. Could not release the brake. Car was idling very rough during this time. Turned car off and back on. Brake released but still running very rough. Made it the short trip home. Truck to dealership via wrecker. Brake was again a problem getting on and off the wrecker

TRAILER HITCHES

A trailer hitch has an sticker stating the Tow Vehicle Maximum Trailer rating for the hitch. Owner's manual and towing safety stickers on the driver's side door only state the maximum dead weight for a hitch...that is the weight applied if a trailer is attached to the tow vehicle's hitch ball. This sticker give you maximum if a trailer is installed with a weight distribution hitch assembly. On my 2025 Silverado, as well on four other Silverados I viewed at a dealer, and a few GMC Sierras, also viewed at dealers, the sticker is applied; however, impossible to read the specifications supplied by the sticker. I have uploaded two files: One, is the sticker as viewed on a 2016 GMC that is attached to the bottom of the hitch, easy to read and obtain the SAFETY information contained. Second photo is how the sticker is attached to my 2025 Silverado (and as noted on all other vehicles I viewed at dealerships) and as you can see, the specifications are not readable. I even tried a mirror and not enough room for the mirror to fit and allow viewing of the stats. The information on this sticker is required to SAFELY pull a trailer with a weight distribution style hitch assembly. And to require a sticker, but not make as requirement it needs to be legible is ludicrous. Thanks

ELECTRICAL SYSTEM

Days after purchasing the vehicle brand new back in 2023, it began having issues with what they thought was the new 4 cylinder mode working itself in or electrical shifting needed to be replaced… After numerous years of being stalled out on highways, unnecessary repairs made, lose of business revenue, and more. It turned out to be a faulty engine with bad bearings, & levers. Over time, got worse & left unseen causing it to officially blow. The shutdown modes prior were all left undetected or resolved by dealership service stations. After being told of suspicious knocking since only thousands of miles out on.
