Unknown..... the transmission in my truck began the shutter and shake like I was running over the rumble strip. The truck was at one point locked into 4x4 and even stuck in reverse and almost got me ran over by a diesel when I couldn't get out of his way until the very last second. Im not the only one with this issue. Gm has been knowingly mass producing these defective transmissions and selling them to the public with no notication to the consumers. This is obviously defrauding the consumers out of not only there money but also many of there livelihoods. As many families depend on there trucks in order to financially support there families. As mine does. Gm sold defective equipment. Completely aware that they where defective this is fraud and they should be held liable for there actions.

I hit my brakes to avoid an accident in multiple -5 degree weather and my trucks transmission shuttered and failed to work. This truck was running very strong before this unexpected event. Chevy owners should not have to pay for this out of pocket. Thank you

I bought a truck from Paul Gerber Auto sales, Inc(used car dealer) in Omaha Nebraska. The transmission is bad because of the torque converter and a known issue where the transmission fluid gets too hot causing the torque converter to become damaged. There are also multiple known safety recalls with this vehicle and the issue with the transmission has been confirmed by a independent mechanic. The dealer had me driving it down roads that didn't take the vehicle through all of its gears so the problem wasn't noticed until after I had gotten on to the freeway. Went on the freeway I noticed that it was shifting up hard and downshifting hard as well as a rumble strip effects in the vehicle struggled to get up to speed or was sluggish. When I was clear and tried to pull out into a lane from an intersection the vehicle struggled to get up to speed and I was nearly rear-ended. That's when I took it to have an OBD reading which caused the check engine light to turn on and notice that codes were pending which means that the dealership cleared the codes before the test drive. Please have not been made aware yet but I will be filing a report.

Vehicle is experiencing intermittent electrical issues, including vehicle completely shutting off while driving, driver window security warning message appears, radio, outside temp and fuel economy will reset when starting the truck. Last time it shut down while coming to a stop, a message appeared on the driver information screen saying “3 key programmed to vehicle”. Sometimes before it shuts down while driving, the radio and dash lights go out followed by engine stalling and there are different messages that appear briefly, like, service stabilitrac, roll driver window down & 3 keys programmed. The truck has shut down on me while operating 7 times in the last 3 months! This is EXTREMELY dangerous as i lose power steering & brakes! It has happened while in the middle of a busy intersection, in a round about, pulling into a parking spot, driveway and while driving straight on a road. I have cleaned & checked all ground locations, replaced the battery and alternator, cleaned battery terminals and Cables, checked all the fuses and nothing has made it stop!

I am writing to report a significant mechanical failure with my 2014 Chevrolet Silverado, which I believe warrants further attention due to its potential safety implications and its connection to a widely documented defect affecting many GM vehicles equipped with Active Fuel Management (AFM) systems. The engine suffered lifter and camshaft failure. This is a well-known problem with GM trucks using AFM systems and can pose a safety hazard, particularly if the vehicle stalls while driving. Failed Component: The engine’s valve lifters and camshaft failed. The components and repair documentation are available for inspection upon request. Safety Risk: This failure caused loss of power while driving, creating a risk of stalling in traffic, which could endanger both myself and other drivers on the road. Confirmed Diagnosis: The issue was confirmed by the dealership where I service my truck, Team Chevrolet in Las Vegas, NV. They identified the lifter and camshaft failure as the source of the symptoms. Inspection History: The vehicle has been inspected and diagnosed by the repair facility. I reported my concerns directly to General Motors and formally requested goodwill assistance and an extended warranty to cover the repairs. However, GM denied my goodwill and extended warranty request despite widespread reports and TSBs. Warning Signs: These warning signs began to show June, 2025 after picking it up from the service department at Team Chevrolet as it had been serviced. The truck was taken back to the dealership within 30 minutes of picking it up.

Why is/was there no investigation in to the torque converters in these vehicles? I have the 5.3L V8. Took it to a tranny shop and he has five on his lot, same transmission same generation all same issue. He says they start eating themselves and he has a few with only five digit mileage that he still needs to fix. A guy in my firehouse is a parts manager for a Chevy dealership and knows the part number for the transmission off the top of his head because they fly through them and he has 19 in stock. Luckily I'm a good driver and when the transmission gave out on the highway I was able to control and get over without my kids getting hurt. But that is two shops confirming this is an issue. It's a safety issue. An expensive safety issue. There's even a tranny guy on Facebook that says the same thing because these are mostly all he works on. I'm a bit shocked you all allowed this to pass through. Granted the shop said the American made parts in the torque converters are the ones failing, so it would look bad. But my kids could have been hurt if my wife was driving and couldn't control the truck. This is an epic failure. Five digit mileage trucks coming in for the same issue. He told me to keep up whatever maintenance I'm doing because coming in at 130k is the second highest he has seen.

Over the course of ownership the chassis of this vehicle has gotten horrendously corroded, which has caused structural components of the frame to begin to develop rust holes needing repair. These holes in the chassis are caused by the incorrect application of the factory chassis wax coating and has caused the entire frame to become deeply rusted through in many areas. Additionally I have been through two transmissions, the first occurring at around 55,000 miles of use, and the second around 105,000 miles. Seems there is a point of failure after around 50,000 miles on these transmissions.

While driving on the interstate my truck starting slowing down fast and the engine RPM's went up. I pulled to the side and restarted the truck i would start driving then the truck would do the exact same thing. While all this was happening there was a burning smell in the truck. I brought the truck to an automotive mechanic and the found the transmission was bad. It is a very common problem with 2014 silverado 1500 trucks with the 6 speed transmission.

The transmission at less then 150,000 miles grinds and causes a vibration through the steering wheel. It is available for inspection if need be. There was no sign of this failure before it happened. It has made the truck unsafe to operate because of it were to fail it would cause a complete loss of power to the drive shaft, and currently is causing intermittent power loss to the drive shaft. It has been inspected by a local Chevrolet dealership as well as an independent transmission shop that both confirmed the torque converter has begun to fail. The local dealership as well as the transmission shop have both stated they have had a large number of trucks with the same issue come in over the last year. The service manager at the dealership even informed me that there should be a recall put out for the issue. I have even put in a complaint to GM and there was nothing done about the issue. I went back and forth with them for months

Transmission failure. At 140,000 miles, metal flakes in the pan. This could cause an accident and I've done some research and found multiple people with this same issue between 2012 and 2016. Also, a transmission shouldn't be needing to change at this amount of miles. Also, I bought this vehicle used with this problem.

The vehicle is now at 158,109 Mi as of January 5th 2024 at approximately 148,000 to 152,000 Mi I noticed the transmission and or the rear differential starting to slip have play and making various noises and sounds along with a jerking feeling where you would hit the gas and you could see the tachometer wind up a little bit and then when it seems the gears would catch or however it works it would jerk you forward with a bang feeling like somebody hit you from behind but there's no one back there a few times I would hit the gas to leave from a stop and merge into traffic and the vehicle would not move at all until 2 or 3 seconds had passed for the engine and transmission to finally catch up with each other or something I've noticed many recalls and problems on these Transmissions as well as the same issues on a previous Chevy Silverado 2014 I had prior to this one I'm very concerned that at some point I'm going to try and enter a traffic situation and not be able to have forward motion taking a chance on being part of a collision due to the vehicle not moving forward as required when you hit the gas pedal. I've noticed signs of fluid around my rear differential cover I continuously check the fluid in the transmission it is always fine I would like to have it checked out as the engine is an excellent motor with no obvious problems I take care of it changing the oil and Performing maintenance regularly as expected and required.
