The truck and transmission shift very hard, slip or can't find its home. The problem is the worst between park and reverse, and 1st and 2nd gear around 20mph. I have taken it in multiple times times and told everything is operating to spec. One time I was told they were waiting for guidance from GM, but then forgot about that, and said everything is fine.

When placing the truck in reverse or drive the transmission does not immediately engage. I purchased this truck new and have had two replacement transmissions for this and other issues. Dealer service department said that General Motors calls this delayed engagement. Dealer also stated that there is a bulletin stating they will no longer replace transmissions for delayed engagement. This is unsafe when the vehicle is placed in gear and the accelerator is pressed to get the vehicle to move and it does not move for several seconds and the accelerator is pressed harder to get the vehicle to move but suddenly the vehicle transmission will engage and the vehicle will lunge and unexpected distance. This situation occurs more often when the truck is sitting overnight but can happen other times also. I am familiar with the situation and usually remember to not accelerate and wait an extended time for engagement.

Fuel injectors causing cylinder misfire - this issue can be very hazardous to the safety of driver and others. First noticed on highway going straight. Then again next morning, vehicle would not start. The date occurred is not exact, but close.

8-speed transmission shifts strange and clunks during slowdown/speed up. Drivetrain feels loose at times and dealer doesn't acknowledge anything iswrong. Also after taking off in morning shifting into second gear there is a hesitation and power drop.

Air conditioning not working. Blowing hot due to worn hole in hose (thousands of known issues all with exactly the same symptoms and fixes... E X a C T L Y!!!!!!) called chev, the guy said NHTSA tells them what to pay for and what to recall so they're hands are clean of this issue. Pardon"???? worn hole? check bad condenser? check no bracket? check dealership/manufacturer participation? no way in hell! this is absolutely terrible business and there's no way the attorney general, the better business bureau and anyone else I can call are not going to hear about this. Oh yeah, the A/C never gets used, otherwise I would've had it fixed 20K miles ago under warranty but I didn't know it wasn't working. There's residue on the hoses from the leak which the dealership should've caught but they didn't. maybe I go that route"

Truck shakes severely when driving at speeds above 70 mph on many different road types. This problem started not too long after I got my truck new. After complaining about it the service department said this is "standard 22 inch wheel vibration." After I had about 35000 miles on it the vibration got so bad I couldn't stand to drive on the freeway. Took it back to the dealer and they said the tires were wore out even though there was still plenty of tread. Had another shop look at it and they found one of the wheels was ever so slightly bent. Took it back to the dealer to confirm. They sold me a new wheel, the problem didn't go away or change in any way. I bought new tires as they recommended, problem was still there but not so severe until after driving a few thousand miles. The more miles I put on the tires the worse the vibration gets. Took it back into the dealer again recently, they keep telling me it's standard vibration for 22 inch wheels. I know this is bogus because I know a few people with the exact same wheels and tires that don't have the shaking problem, they can drive as fast as they want and it's smooth. Everybody that rides with me asks what is wrong with my truck. How can I convince the dealer that there is an actual problem?

Is a noise from the transmission between 40 and 50 miles an hour, and is also a clunking noise when shifting in traffic.

Transmission doesn't shift right between 2 and 3 and on down shifting. Never drove a vehicle that does this. Was told nothing is wrong with the trans.

I had an issue with the transfer case got stuck in 4hi and at the time it had a recall so I took it to the dealer located less than 20 miles of my house I never got over 45 mph while stuck in 4hi dealer did recall which fixed the problem for about 7 months then when I was hauling a 18 ft car hauler with a small truck on it and I only had to haul it 30 miles to my house I was about a 1/4 mile from my driveway and the rear end popped really loud 1 time and then all of a sudden it started grinding and I shut the truck off and called roadside and had it towed to dealer and I received a call from the dealer they said that the spider gears had broken and it was going to cost 3000 for a new rear end do to the cross pin retaining bolt had broken inside the differential carrier assembly I decline the service because I didn't see why I had to pay if I still have warranty on it and I had another rear differential carrier assembly and had it installed which it worked fine except that the when the original rear end broke it said service 4WD and it still said that when I got the rear end fixed and I took to the dealer and they told me that it would cost 130 just to look at it and if they found anything wrong with it that that 130 would go toward repairs and as I said before it is still under warranty and is only got 47000 miles and I took it to a friend's shop that has a snap on computer and pulled codes and researched the codes and what I found was that the transfer case shift module re learned or reprogrammed and that would fix the issue which a lot of other 2014/15 Silverado owners have had the same issue with the transfer case and relearning or reprogramming fixed the issue.

Transmission shifting rough, sometimes when shifting into reverse it bangs loud, thinking the drive shaft is going to fall out, when driving the shifting of the transmission jerks nothing smooth about it shifting

Under acceleration and cruising highway speeds the vehicle vibrates and shakes. It is felt in the floorboards, seats, pedals, steering wheel and in the bed of the truck. Vehicle has been into the dealership numerous times getting alignments, wheel balances, and pico scope tests. Under my own investigation I found the factory driveshaft was not straight, out of round and out of balance so I had a professional driveline shop build me a new one. Also under my own investigation I found the rear axel hub flanges were out of round as well and the local dealership had replaced them. Vibration still exists and there seems to be no answers coming from GM.

This truck has the 6.2 and 8 spd trans. I start it up in the garage and let it idle down, back out of the garage into the street, put the car in drive and feel it engage, push on the gas and it doesn't move for a few seconds or now it will move but then when it tries to do the 1-2 shift it won't shift and the truck stops moving forward for a few seconds until it finally does shift. I had it in to the dealer at 13K miles and they determined there was a problem with the stator support in the trans allowing the converter to drain so they did a partial trans rebuild and updated the parts. The original problem is showing up again along with the 1-2 shift problem. I took it in again at about 18K miles and the dealer said that they could reproduce it and the issues is caused by the "clutch" not being filled with fluid at the time the shift is trying to happen. Once the clutch is full...it shifts. I was also told by the dealer that this is a documented issue with GM and there is a bulletin out on it telling dealers this is normal and to not do any repairs trying to fix so they did a software update and put the trans back into learn mode said they were sorry and gave it back to me. This condition is an accident waiting to happen when you expect the vehicle to move and it does not. This transmission is installed in Chevy, GMC, and Cadillac trucks and SUVS and there many complaints on all of the popular message boards online about this exact same issue. Some people have complained about almost being hit in the rear because there vehicle won't move. There are many other documented issues with the 8 spd trans GM has been using in their trucks as well and GM will not address any of them saying that they are all normal. I have talked to plenty of other people personally that are experiencing the same issues as well and not getting anywhere.

When shifting into gear transmission makes load noise.

Truck shakes at speeds at 55 to 65 miles per hour.

- Forestdale, MA, USA

So due to known issues with the yolk on the differential, the lag in the transmission shift and engine communication leads to extreme vibration at highway speeds and clunking and jerking while driving around town. So when the transmission shifts there is a delay in the motor recognizing it so it revs up some so when the transmission finally finds the gear it causes it to kick. And since the yolk has play in it, it causes the differential to clunk as the rotation of the driveshaft catches up at a quicker rate. Which leads to more looseness in the yoke and creates a wobble in the driveshaft. And an unsettling sound while driving around.

At highway speeds between 58 and 74 mph, there is a vibration that shakes the truck. My first trip to the dealership, they said 3 of the 4 tires needed to be replace, which was covered under warranty. The truck had approximately 3500 miles, when I took it the first time. The problem was stable for a few thousand miles, and then started to get bad, I called and scheduled an appointment, and the truck has been at the dealership for over a week now, and they have replace the one tire that wasn't orginally replaced. They also said they are looking at the exhaust system.

While driving on the expressway, the drive shaft broke off. This caused the vehicle to lose control. Luckily, the vehicle was able to make it to the side shoulder without causing an accident. The dealership replaced the drive shaft and rear differential, but no one (even when I contacted GM priority care) could inform me why this happened. With me having two small kids, I am still concerned that this could happen again.
