When at highway speeds (anywhere between 40-75) there is a very noticeable shaking when engine is under light load (just keeping speed). I have taken in to Chevy dealership and they changed the transmission fluid and that worked for a couple thousand miles. Not the "Chevy shake" is back at full force. Upon calling Chevy, they claim to know that their trucks do this, but say there is not a fix to solve the issue. They claim they have no clue where it's coming from, but should not be a safety hazard. My question is, if you do not know what it is, how can they say it's not a safety hazard. I am so afraid that my truck is going to break down and it's not even two years old. I have read the thousands of complaints online with people having the exact same issue, since the 2014 model. They have had enough time to figure this out and should be held accountable.

The transmission shifts hard in low gears (upshifting and downshifting), lunging forward and a hard knock in the transmission. Chevrolet cannot fix it!

- Charlotte, NC, USA

8 speed transmission harsh jerks between 1st and 2 gears and 2nd and 1st gears typically occurring on slight downhill grade harsh jerk and knock/hammer noise common to occur after vehicle has been sitting and in stop and go traffic such as school drop off with children around and rush hour traffic

Transmission started slipping at 72000 miles, replacement or rebuild.

- North Little Rock, AR, USA

Shortly after purchasing my truck, I began experiencing hard shifts, gear searching, clunking and hanging between gears. Occasionally the shift would be so hard it would feel as though the truck was struck from behind by another vehicle or object. Multiple trips to the dealer has resulted in numerous attempted fixes with no relief of the problem. Currently the truck is back at the dealership having the entire transmission replaced. This is causing a depreciation of the value of the truck as well as an unsafe condition while driving.

Truck transmission was good until about 2,000 miles. Truck has delays when putting in gear after it sits overnight. Truck has harsh low speed downshifts. Problems are real bad when vehicle is cold. When you come to a complete stop and let off the brake the truck will sometimes lunge forward. Took truck back to the dealer where I bought it and they said nothing was wrong so I made an appointment for a week later with another dealership. They did a "timing" test and felt the delay and did 16na364 update. It seemed to help for a couple of days and problem returned. Both dealerships are aware of the problem but GM is not providing a fix. I now warm the truck up a few minutes before driving to help with delayed gear engagement. Harsh downshifts continue with the lunging and slow response at times when applying gas petal. You have to be very careful when driving this truck because of the transmission problems. There are many complaints for this not to be a major problem. This vehicle sticker price was $64,000 dollars. I wish I had my old truck back because it was reliable and not potentially dangerous to drive. General Motors need fix this problem or at least give an free extended warranty. The dealers will fix the transmission if GM will tell them how.

Very hard shift going from 1st to 2nd gear and from 2nd gear to 1st gear. The shift was so hard that the tires made a chirping noise and hardly any throttle was being used.

- River Falls, WI, USA

Experiencing hesitation/'chuggle'/convertor slip in 2nd-6th gear in V8 mode when rolling into the throttle and putting the engine under load on a highway. Especially noticeable when in 4th 5th or 6th gear,1500-1850 RPM, loading the engine to accelerate 55-60mph, 60-70mph. Or when accelerating on an incline at same speeds without downshifting. Or when slowly applying throttle to maintain speed (65+) against a head wind or when trying to pass a car. All while maintaining current gear and no downshifting.

- Overland Park, KS, USA

At low speeds under braking when downshifting from gear 2 to 1, the shift is not smooth. There is a significantly loud clunk that you can feel and hear, and passenger safety is compromised due to a sudden lurch forward.

- Wakefield, MA, USA

I bought my pickup brand new from a certified Chevrolet dealer and have had an issue since I test drove it. When shifting under low throttle from 1st to 2nd gear and back down from 2nd to 1st, there is a terrible clunk. Sometimes its barely noticeable, and other times if feels like I've been rear ended. There is an extremely noticeable hesitation when starting off from a complete stop, which could potentially put myself and other drivers in danger. I've brought my vehicle back to the dealer multiple times and have been told that there is no fix.

- Henderson, NV, USA

When going slow and the truck shifts from 1st gear to 2nd gear you can hear and feel a strong knock and it pulls the truck this also happens when going down in gears from 2nd to 1st at slow pace and it doesn't happen all the time but more often then not if your driving slow like in a parking lot it happens 6/10 times took it to the dealer stated no recall but they are aware of the issue but were instructed not to do anything to the truck verified google and a lot of other people are having the same issue

- Las Vegas, NV, USA

A rough clunk noise occurs when trying to stop, and car actually revs to accelerate speed when applying breaking and trying to stop. (in. Motion) this is a dangerous issue. Transmission does not appear to smoothly enter into subsequent gears. A jerk occurs in between shifting of gears. (moving) I have been completely stopped on a flat street, and relax my foot off the break, and the car wants to leap jump forward. This is not safe. (stopped) there are several reports of this issue found in online forums from other owners with the same 2017 Chevy Silverado. Just purchased vehicle in November.

- Huntington Beach, CA, USA

The truck has a hard time accelerating and randomly upshifts and downshifts. When coming to a stop it has a hard time downshifting which makes it hard to stop. When on the interstate in rush hour traffic it is very dangerous to drive because I have no idea if the truck will accelerate or not and since it has a hard time stopping I am afraid I am going to rear end someone. Another issue the truck has is with the four wheel drive. It works good but it makes a really loud grinding noise when engaged. I am taking it to the dealer today as I have before. I am hoping they take a serious look at it and fix the issues.

- Blue Springs, MO, USA

6.2L engine with 8 speed transmission. Erratic transmission shifting including downshifts so hard on the highway the rear wheels will lock up momentarily and throw occupants forward. Taking off from stoplight will intermittently experience delayed engagement and engine will rev to almost 1500rpms before the transmission engages. Tires bark, scares the heck out of driver who them immediatley slams on brakes in traffic thinking something broke. Dealership cites normal operation with no fixes available from GM. Lots of similar stories online and the first class action suit against GM for these 8 speed transmissions has been filed.

Transmission downshifts rough.

The pickup shakes at speeds typically between 30-45 and 55-75. It shakes hard enough and long enough at times where at higher speeds becomes dangerous because it compromises the steering where the truck can come off its line and become unstable. It will also shake randomly and for unknown periods of time. When it starts I have no control over it and no control over when it starts or stops. I have brought it into the dealer a couple times now. The first time they said I needed to rebalance the wheels and put on new tires so I did both. The second time they said it was a problem with the engine/drivetrain when it deactivates 4 cylinders. They told me there is nothing they can do for this problem. I have researched this and it seems that it is a problem with this specific engine and GM is claiming there is not a safety issue. This is completely false as the truck becomes unstable and steering is compromised. At highway speeds this is a huge issue especially if this continues into winter months where road conditions are not the best.

6.2L engine had faulty injectors and had to be replaced. GM said my truck had a warranty block so I had to contact the BBB and go to mediation to get injectors replaced. Now I'm noticing a shudder (vibration) while driving with a fluttering of the RPM's. all my research has led me to believe it is a faulty torque converter. My wife has a 2017 camaro that is having the same issue. Dealership stated that they are replacing the faulty torque converters in vehicles with 8 speed transmission, but will not replace mine because GM has put a block on my warranty. GM cannot provide any evidence giving them reason to block my warranty on my vehicle.

When driving veh shifts hard causing a jump or unexpected acceleration. Brouht it to huntington Chevrolet they stated it was normal. I do not feel safe in this vehicle.

- Kings Park, NY, USA

8 speed transmission clunks when shifting into 2 gear and at times feels like you got rear ended. When it down shifts into the lower gears it's also clunks and is not smooth. This is happening when going at slow speeds and is worse after a cold start. The vehicle shifts fine at hwy speeds. I have already brought it to the dealership twice and problem is still there. Talking to other people with GM 8 speed transmission and they are having the same issue. 8 speed transmission needs recall. Possibly torque converter.

- Elk River, MN, USA

Engine hesitation, or misfiring. Jerking, or transmission shuttering when engine is at low RPM and on incline. (I.e. when traveling about 45mph and start up a hill, the RPM's are about 1300, and the transmission doesn't gear down, so it starts shuttering until you give it more acceleration than usual.) after dealing with this issue for nearly 8 months and 15K miles, I believe this safety issue should be recalled. Dealer originally acknowledge the problem but was unsure of the cause. After 5 repair attempts the dealer say they can't duplicate and the vehicle performs as designed.
