My truck had approximately 10 miles when I purchased it in Dec 2014 and has been in the shop pretty much ever since. Immediately after purchasing the vehicle, I felt a very substantial vibration around 76+ mph. Initially, 2 tires were replaced and balanced; that did not correct the problem. Then the dealership indicated that GM said I have to put 500lbs in the back of the truck and the vibration will stop; this is not even remotely practical. Subsequently, the tires have been rotated and force balanced several times throughout the past 2 yrs. In June 2016, the dealership stated the problem was that the tires were mounted on the rims incorrectly and replaced all four tires and balanced them; the vibration continued. After trying to schedule another appointment with the dealership over the same issue, they will no longer call me back. I have attempted to schedule an appointment at least 8 times within the past month to no avail. Several people have indicated the problem is quite possibly the drive shaft B/C the entire truck vibrates while driving down the road. Therefore, I took my vehicle to another dealership where they told me I need to rotate and balance the tires. After discussing the history of the truck with them and requested the service dept. Check the drive shaft, they stated the service manager said it is not the drive shaft (which was not inspected to my knowledge) and told me the tires need to be forced balanced and they could not help me. This dealership referred me to another dealership for assistance. I have been fighting this issue for almost 2 years now and cannot get help. Further, neither of the dealerships have made me aware of the bulletin and have not tried anything past the replacing & balancing the tires. The vibration is so bad other things in my truck are starting to come loose and vibrate.

Transmission is lurching if driving 50 mph then slow down to 35 mph when you go to speed back up it lurches. Complained to Chevrolet several times they say cannot find anything wrong.

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 contact owns a 2015 Chevrolet Silverado 1500. While driving 10 mph, the accelerator pedal was depressed and the vehicle accelerated in excess. The vehicle was taken to a dealer where it was diagnosed that the wiring harness, part of the transmission, and multiple other parts needed to be replaced. 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.

The vehicle was taken to two dealers who were unable to replicate and diagnose the failure. The manufacturer was notified of the failure and provided no recommendation or repair solution. The failure mileage was not available.

While driving at speeds starting at and above 70 mph there is an audible noise not present at any other time or circumstance. This is also felt thru the gas petal so my concern is that there could possibly be a defect or out-of-balance component. I demonstrated this condition with the dealer's technician on this and another identical 1500 and it had the same issue. Discussing this with another 2015 Silverado 1500 owner found that their vehicle also has the same condition. In fact their vehicle when operated at speeds above 70 mph vibrates so noticeably that the cup holders spill the contents.

My Silverado has developed a vibration around 4-5000 miles from new. The vibration starts around 60mph and increases in intensity up to and beyond 80mph, the legal speed limit in Texas. The vibration can be felt throughout the cabin in the seats, center console, steering wheel, doors and gas pedal. On my last 3+ hour drive I had to stop midway because the vibrations gave me a headache. That's never happened in any other vehicle ever. After 3 visits to the dealer and multiple road force balance and tire replacements later the dealer states the truck is operating normal and is in spec. This is unacceptable for a brand new vehicle and I'm working on taking it to the next level with GM to deal with the problem.

Had been complaining since 2 days after purchase that transmission was shaking/shimmying/sputtering. Was pulling onto a county highway off of a residential type road (after picking up granddaughter from school - she was in truck) and truck bogged down & wouldn't go. Intersection is at top of hill and around a corner. Was clear when I started pulling out, but was almost hit by oncoming truck before I got my truck to get on across the intersection. Has been in shop twice to fix it. First time to double transmission flush. That didn't work. Next time a few weeks later, a technician hooked up a computer to my truck so he could manually shift gears while riding with me. He felt the issues and said he saw several problems. Dealership ended up replacing torque converter. Also replaced vlom manifold - whatever that is? that's what it says on work order. The problem still exists. I believe there are bulletins out on this truck's transmission already. I have talked to others who have had the same problem.

I have a 2015 Chevy Silverado 1500 4X4 with 5000 miles. While driving to work ( less then 2 miles) my service 4WD system warning came up. The truck is stuck in 4WD can not switch it out. Also while stuck in 4WD turning is very difficult. Called dealership they told me it was safe to drive it in. While on my way to the dealership still stuck in 4WD my check engine and traction control lights came on. The truck started to shack and shifting at random and the RPM were all over up and down. I got to the dealership and checked in they took it for a test drive while I waited. After waiting 4 hours they tell me the engine has issues they don't know what or why and that it will be a few days before they will know anything. So that waiting game begins.

October 31, 2014 on my home from work I heard a bang. The truck pulled very hard to the left taking me into the concrete barrier that divides the highway. Vehicle was in motion us highway 41/45 65 mph. After the truck was investigated at the dealer to give an estimate on the damage it was discovered the left rear axel was broken. Questioning the dealer about this issue and not getting anywhere I talked to different mechanics that I know after a week or so it was discovered there was a recal for insuffcient heat treated rear axles talking to the dealer and I was told this did not pertain to my vehicle as the recall was taken care of at the factory. I cantacted Chevrolet and was told that because I had given the ok for the dealer to make the repairs. My insurance company would need to fole paper work against Chevrolet which myself I believe is wrong. I was also told by the dealer broken axle was typical of this kind of impact. There is no damage on the side panel or rear of the truck I do have pictures on my phone which I have not downloaded to my computer.

Has a vibration at 65, turns into a bad shake at 75.

- Kirklin, IN, USA

Takata recall I was traveling down the highway at approximately 75 mph when I was accelerating over an overpass the vehicle began to vibrate with an associated humming noise and after about two seconds after theach vibration started a very loud and violent banging sound came from under the vehicle that was felt from the inside. I immediately steered to the highway shoulder, because I could see metal chunks tumbling from behind the vehicle from my rear view mirror. Once I was on the shoulder I looked under the truck to see the drive shaft had come apart from the transmission with the U-joint still connected on the transmission side. The drive shaft was mangled on the transmission side, and the exhaust was crushed with holes in it. The tool road authority stopped to render aid and kindly towed my vehicle off the tool road to the nearest gas station. Images were taken of the damage, but we're to big in size to upload.

Transmission cannot find gears when coasting or slowing down and then hitting accelerator. Very dangerous when it hesitates for seconds before finding the right gear and going, or it stays in too high of a gear instead of downshifting to accelerate and rattles. Happens every time I drive the truck, and many other people have the same issue. GM doesn't care!

I purchased a new 2015 Chevy Silverado 2500hd duramax crew cab lt from auto nation of pembroke pines Florida and at about a week or two of driving it I started to notice a bump/clunk from the rear of the truck just as I would come to a complete stop. It also does it just apon a strong acceleration. The vehicle had about 500 miles on it when I started to notice this. I brought the vehicle in for the first oil change at about 4K miles and told the service guy what was going on. He said they would test drive it. When I picked it up he said they could find anything wrong. I think it's the slip yoke sticking and needs to be lubricated or replaced. Some of the older truck had this issue.
