While driving at low speeds (approx 5-10 mph) the brake pedal became stiff and very difficult to stop. This issue happened with no prior warning or indication of the issue. As a result of this issue severe damage to personal property housing and vehicles was nearly missed. Upon research this has been a common issue for GM vehicles specifically trucks and SUVs.

My wife came home and told me there was something wrong with our truck. I went and inspected it and found nothing. The next day i drove the truck about 30 miles up river. Coming home I was traveling around 55 mph the truck came to a sudden slow down as if I had locked up the brakes then drove fine again. This happened three or four times not as bad as first time. While in town stopped at a light it tried to take of. Not like something giving it gas but like it was in gear and the brake wasnt going to hold it. Almost put me into a school bus ahead of me. Then the rest of the way home it kept binding down and releasing then binding back down. Hard to control but not necessarily a break problem. Its something else. I have worked on vehicles all my life, professionally for 25 years. I never seen a vehicle do this. It has to be in the transmission. Maybe something in the torque converter would be my guess. I have heard of the issues with the 8 speed ever sense this happened I have parked this truck. I cant afford a need transmission that doesnt actually fix the problem from what i hear. I feel GM needs to do something here. At least pay for the parts to fix

I am having issues with my transmission. When I first turn on the truck in the morning, put it in gear, and lightly accelerate the truck accelerates way too fast then cuts out the power. It is enough to throw me forward or back in my seat and it honestly is frightening. I am also having problems with the vehicle shifting incorrectly causing me to have no power or a sudden surge of power. This is usually when i have slowed down and them am trying to accelerate again. Also, When I am slowing down to stoplights, the vehicle will occasionally shift down to too low of a gear and act like i am slamming on the brakes. I have had several close calls with this truck due to this issue. Gm knows about the issue and has refused to recall the vehicles that are having these problems. They are recommending changing out the fluid multiple times at the owners costs. This has resulted in several class action lawsuits. They also have gone to the lengths of changing warranty coverage to no longer include abnormal shifting. This is not safe. This is causing accidents and they are actively covering it up. Please help the hundreds of thousands of people that are having issues. We need your help, I need your help and gm is no longer standing behind their vehicles.

The system that failed is the speedometer display and radio display while driving. This can be dangerous as I do not know the speed I am driving. This can also be dangerous as the display includes the screen for the backup camera that turns off without notice while backing up. The problem has happened many times in my 2015 Chevrolet Silverado. I have a 2017 Chevrolet Silverado for a company vehicle and the issue occurs in it, as well. I notified the GM dealership where both vehicles were purchased and they said the screen could be replaced but would be very expensive. No warning lamps or messages occurred. The screen jumps around a lot and occurs at various times (morning, afternoon, warm or cold weather, etc.).

Rpms were rising above 6,000 without any power. Randomly while on highway, truck only had 112,000 miles on it and had to have a new transmission put in. And has had many other issues such as the lifters closing while on the highway and brake issues. The worst model truck ever made.

Transmission problems. When reversing up a driveway the truck will stall as the gas is pressed it will rev up but not go anywhere, then jump into reverse as if the petal was floored. Also some times when entering the highway the transmission doesn't shift into the correct gears also jumping into gear which could cause accidents.

Purchased new 2015 Chevrolet Silverado 1500 in January of 2016. Experienced a vibration at all speeds from the very beginning of purchase. Vibration gets worse at higher speeds. Vehicle came with steel wheels from the factory. Vibration can be felt in the seat and seen in the center console. Vibration is coming from rear of vehicle. Replaced wheels and tires with aftermarkets. The aftermarkets were bigger and heavier and made vibration extremely worse. After assuring that I wasn't dealing with a problem with the new wheels and tires, I put the factories back on and took the vehicle to dealership and reported the problem. The vehicle was in the shop for 3 1/2 months. The vehicle failed pico scope tests. They put several new tires on the vehicle, changed both rear axles, and changed ring and pinion in rear end. These steps helped reduce the vibration, but did not totally resolve the issue. They then decided to put aluminum wheels on the truck, which helped reduce the vibration down to barely noticeable. My concern is by putting the lighter wheel on the vehicle to reduce the vibration, they are only masking the problem, since the heavier the wheel/tire assembly, the worse the vibration. They are telling me they do not have to do anything else to the vehicle. General Motors has told me they are not going to pursue the issue any further. They tell me they know there is an issue but not sure what it is and since it is not a safety issue they have honored the warranty. How do they know that it's not a safety issue if they don't know what the problem is. I believe they know exactly what the problem is and they are passing it on to the consumer. There was no disclosure of the issues with these trucks upon purchase. I do not feel safe in this truck and fear future problems with the issue. Also, the truck on several occasions has down shifted abnormally causing rpms to rise.

On Sept 21 2016 I arrived at my home. I drove up my gravel driveway in D(drive) and slowed to a stop and my truck began to roll backward under my control. I was checking on the ground for lawn damage. The truck shuttered twice, shut off and started to roll backward toward a tree. I quickly regained control with a panic stop. I was able to place the truck in park and restart the truck. I had lost control of the truck.

I park in a 5 level parking garage. Several months ago, I was leaving when I came up to the ramp to the next lower level. I let off on the accelerator before I went from flat to lowering ramp. The truck shifted up to second gear, accelerated and through me toward the vehicle in front. The truck went out of my control. If I were not a safe driver I would have struck the vehicle. This issue has occurred another time as well. There have been other problems which are numerous. I will address them individual in further complaints.

The vehicle was repaired; however, the failure recurred. In addition, while driving at a very low speed, "haul gears" displayed on the message board as the vehicle switched into a low gear independently. The manufacturer was notified of the failures. The failure mileage was 3,000. The VIN was unavailable.

A reproducible condition exists when the driver removes their foot from the gas pedal, then quickly engages cruise control, then pushes the minus (-) button repeatedly to decelerate the cruise control, that the vehicle cruise locks up and flips back and forth between the desired speed and the original set speed, and does not decelerate. This can occur for several seconds, where the driver believes they are decelerating the cruise control but it is locked at its original setting, which could lead to an accident.

While driving my 2015 Chevrolet Silverado 1500 ltz with a 5.3 liter motor the RPM of the engine act erratic, it will increase and decrease RPM at will, I would say that it surges about 75 to 150 RPM, it especially does this going uphill. It is unsafe to be driving a vehicle that acts in this manner because you can't control the way you want to drive, I took it back to the dealer and they are trying to convince me that this is normal, which I know it is not normal, GM needs to figure this out and correct the problem.

I purchased a brand new 2015 Chevy Silverado and in the first week I had it, while driving, the truck just simply completely shut off. Dealer claims they have never heard of this and after keeping truck for days stated could not find any issues. About one month later remotes not working and truck warning that emergency brake is on even though it was released. Could not get to register that emergency brake was off and while driving none of the turn signals were working as to truck warning to pull over due to vehicle emergency brake was on. I have only made one payment on this new vehicle and truck has already been in shop 2X.I need your help, please as dealer not helping me and I do not feel safe in this truck. I should not have to worry about it turning of or anything else as to being a brand new vehicle. I have attempted to speak with several managers and one just stated to me" that is why you have warranty and just keep eye on it." Since all this I have searched on the internet, and discovered that this has happened with other Silverado.. ed bozart chevrolett still claims no knowledge of this. Please help me. I feel this is potential accident issue. The first issued happened while driving on craig road which could have been really bad as this is a 45 mph road, luckily it was a weekend and not busy. I don't know what else to do. Spending over $40,000 on this truck not expecting to feel unsafe while driving.
