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.

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.

The return line from the transmission cooler is rubbing on the bumper mount bracket. My vehicle has just over 9000 miles on it and the cover around the line is already worn through. The way the line is mounted offers no flexibility to push it away from the bumper bracket. This will eventually lead to a failure of the return line on the transmission cooler. I was informed of this issue by a post on a public forum. The person that posted this issue had a failure of the return line in the same spot due to the same issue.

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.

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,

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

- Big Spring, TX, USA

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
