Truck down and upshifts hard. When slowing down for a car in front of me, when I get back on the gas, the truck has no power like it can't figure out what gear to be in. Makes a loud clunking noise with light acceleration from 1st to 2nd gear. There is major hesitation when trying to down shift no matter what gear I'm in. Problem needs to be fixed before someone gets injured. Been to Chevy 3 times for the same problem and all they tell me is the transmission will learn how you drive. They also told me there is no new update for the transmission module so I'm screwed.

The 8-speed automatic transmission exhibits numerous issues. 1) when slowing down to under 10 mph, as if you were yielding to traffic and then pressing the throttle to accelerate the vehicle, two issues can occur. First, the vehicle's transmission can hesitate between gears, providing no power to the wheels. Second, when vehicle does shift into a gear, the vehicle can lurch forward unexpectedly as if you were hit from behind. There is sometimes an audible "clank" when this issue occurs. This issue can prevent a driver from successfully entering traffic due to loss of instant power to the wheels. 2) during low-speed acceleration, the vehicle can hesitate between the first three gears, providing no power to the wheels. It has a similar feel to a transmission that was slipping. This can cause a driver to over-correct the deficiency in power to the wheels by applying excessive throttle and cause an accident. 3) when proceeding slowly in stop and go traffic, the vehicle can shift up or down suddenly, causing the vehicle to lurch forward unexpectedly. There is sometimes an audible "clank" when this issue occurs. This can cause the vehicle to strike the rear of another vehicle, in tight traffic, if the driver isn't prepared to apply the brake when the event occurs. 4) when driving normally, the transmission may hesitate to downshift when the accelerator is applied as would be necessary when trying to pass a vehicle. This does not appear to be gear dependent. The loss of instant power can prevent the driver from successfully overtaking another vehicle in the event they need to conduct a passing maneuver.

2017 1500 Silverado, jerks, surges, during acceleration. Now and then I get a loud thud in the rear like I got rear-ended. When coming to a stop from 2nd to 1st.

- Marlborough, MA, USA

Driving from Connecticut to South Carolina my truck developed a bad vibration between 45mph to 70mph. The dealer says that the transmission needs to be flushed. This vehicle has 34K for miles. They claim that no damage is being done to the transmission. This I believe is a safety issue and should be recalled. The vehicle is still at the dealership and my family and I are stranded while they claim that GM needs reading before they can flush the transmission fluid.

Transmission has stopped working properly.

- Southlake, TX, USA

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.

Transmission started slipping at 72000 miles, replacement or rebuild.

- North Little Rock, AR, USA

Rear wheel bearing adjustment nut, stripped the threads and became lose, causing additional damage to the break rotors. It also caused the seal on the rear axle to leak. Took in to mechanic to see why it was leaking. Mechanic was surprised that I didn't lose a rear wheel. Will provide photos from mechanic when available.

- Santa Fe, NM, USA

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

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

Right rear wheel hub nut backed off damaging housing spindle threads and slightly bending the housing. GM will not replace housing even though it appears that a crack is forming where it was stressed.there is a recall for this problem but my truck is not involved. GM will not check the left side like the recall says should be done also.I believe that there is a crack starting to form and could be a problem while driving in the future.

- Norfolk, 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.

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.

- Coalton, WV, USA

Vehicle hesitation and surges in acceleration. This condition is a safety issue as it hesitates pulling into traffic, surges in acceleration have caused loss of tire traction on ice covered roadways nearly resulting in a collision. Dealers have acknowledged an issue but advise they are still waiting on a fix from GM.

Recently I have been noticing my Silverado with less then 20,000 miles has had really low oil pressure. Around 15-20 psi at idle and the transmisson slams into gear,

- Zelienople, PA, USA

In June of 2017, I bought a new Chevrolet Silverado. It runs great no problems. In November 2017 I called to make an appointment to have the oil changed. The service department told me that there is a recall on the chuggle drive quality. The service did what was needed to be done. I had to make a 5-hour trip up North when I noticed that my truck wasn't running like it was before the recall was done. I noticed that the transmission was shifting hard. When the cylinder deactivation went to 4 cylinders the engine lugs. Before the recall was done I couldn't tell when the cylinder activation was switching to 4 cylinders back to 8 cylinders it ran very smoothly no lugging of the engine. What concerns me now is when I was driving an went to make a left turn at slow speed the transmission downshifted hard where the back wheels locked up. Went through a drive through after I placed the order proceeded to the window my truck lunged forward from first gear to second gear. I am glad that no one was in front of me. I have taken it to the service department at the dealership several times. Was told nothing was wrong no codes came up. Even called GM got nowhere with them. The chuggle drive is a reprogramming of the transmission control module. GM trying to fix one problem created another problem. I pull a 5000-pound camper with this truck with the issues I am having now with the transmission shifting hard and engine lugging I am afraid it might cause me to have an accident. My truck ran perfectly before the chuggle drive quality recall was done. The recall has to be the problem. It's not a good fix.

Noticed after purchase that there is vibration like a bad tire 35-42 mph. Vibration felt in seat, console and steering wheel 58-65 mph. Transmission down shifts hard sometimes feels like being bumped from behind, it also hesitates and jerks after letting off the accelerator and accelerating again between 25-45 mph. When accelerating it surges, jerks and stumbles. Sometimes when accelerating the transmission downshifts and hangs in that gear until you let off the accelerator. Under heavy acceleration there is vibration in the power train and the transmission seem noisy. At 25 mph it shutters like the transmission is in to high of a gear under light acceleration. Returned to waldorf Chevrolet where I purchased it and was told they balanced 2 tires and reset the road force, scanned transmission no codes transmission ok after shop foreman road tested for 21 miles no other repairs needed. Picked it up driving home noticed all the problems were still there and after inspection of my wheels noticed that the wheels were balanced still had the old weights still on the wheels with new weights also. Made another appointment this time to have shop foreman (rick) ride with me to show him what it was doing which we did and left my truck again. After 8 days I am told it was ready I was told they did a pico scope test and the driveshaft was being replaced then only tested it was ok. Checked run out on flanges all within specs. Found the right rear tire bad. They put steel wheel from another truck on and road tested with no change. They drove another truck and it rides the same. Even has the shutters on hard acceleration. Said they called GM tac back and they don't see a problem with this. Written documents be sent via mail. Made another appointment

Possible piston malfunction

Transmission shifts extremely hard causing a loud clunk and the vehicle to lunge forward. This is experienced a lot during slowing down at yield signs or when starting out in traffic. The truck experience a split second delay in acceleration and then suddenly shifts very hard lunging forward. GM motors dealership acknowledges there is an issue, but they don't have a solution and GM engineers are having them tell the consumers the transmission is operating as designed despite their own service techs and service managers and district managers stating there is a problem. After 3 different attempts to get this resolved I filed a compliant with GM case # 8-3228178744 that remains unresolved as of today. There are thousands of GM 8-speed transmission owners highly upset over this as many if not all escalade, corvette and truck owners have this issue. A mandatory recall is in order. In my opinion this is clearly a safety issue that should be addressed before someone is seriously injured.

The contact owns a 2017 Chevrolet Silverado. While the vehicle was parked on a sloped driveway without the emergency brake engaged, it rolled out of the driveway. The contact found the vehicle in the middle of the street still locked and engaged in park. The contact parked the vehicle back in the driveway with the parking brake engaged. The vehicle was not taken to an independent mechanic or dealer. The manufacturer was not notified. The contact read online that this was a common failure with 4X4 vehicles as the transmission transfer cause would inadvertently shift to neutral when parked without the emergency brake engaged. The failure mileage was 31,000. Updated 10/25/17 updated 10/26/2017
