2014 Chevrolet Silverado ltz crew cab transmission fluid was serviced in 2015 at 48,900 miles. Still experienced hard down shift and told by the dealer this is because its a truck. At 100,763 miles the transmission begins cavitating, loss of power while traveling and with loud intermitting sounds of metal on metal. Got the truck in for local transmission service and the service manager said the transmission fluid was burnt and littered with heavy metal fragments from the transmission gears. Other local (friends) of 2014 truck owners have reported this condition which all resulted in a transmission rebuild which is $4,000 for this vehicle. The strange problem is they are failing at 100K miles and the dealer has been sent service advisories to not warranty any powertrains after 100K miles even if the date is still effective. This truck was in motion when the cavitation began and shortly after (100 miles or so) began metal on metal sounds and loud clacking form the transmission area under the truck. If you need any further information to look into this don't hesitate to contact me at your convenience. Just a quick background, I am a long time Chevrolet owner and have a 1998 K 1500 and have replaced the engine and replaced two transmissions so I know it doesn't last forever but I would hope Chevrolet wants to know this is happening in their premium line up of trucks. I would only hope the power train would last longer than 100K miles. Thank you for your time!

My 2014 Chevrolet Silverado has the Chevy shakes at highway speeds. The truck begins vibrating at 70-80 miles per hour. Begins to reduce the shaking between 80-83 and then shakes even worse at 85+mph. The shaking is so bad it causes water to shake out of a cup in the cup holder. Not only does the steering wheel vibrate, but the entire center console, and the front seats. The vibration didn't begin until I hit 60,000 miles and seems to worsen with the higher mileage. I now fear for my safety, because I skidded the in the rain due the vibration at highway speeds. I only have videos showing the vibration. Total bummer. I had my tires checked and balanced (which have been on the truck for 1 year +, prior to the vibration starting) my truck has lifetime alignment on it, and this is not the issue either.

Incident occurred on May 27th, 2018. At 65 mph (interstate) going on a downhill grade of approximately 6%, towing an approximate 2500 lb trailer with wet roads to slow the truck down applied brakes lightly, the transmission upshifted (higher RPM), applied brakes again, upshifted again, did a third time, upshifted again (now at 4000 RPM). Had to tap the gas to get the truck to downshift. Transmission was set in drive, not manual mode. This is a repeatable condition; it does not matter if trailer mode on the transmission is selected or not. Less downgrades (approximately 3% or less) do not seem to cause the issue. Transmission programming seems to have an error. This is highly undesirable and could lead easily to an accident.

Truck shakes/vibrates at highway speeds above 65 mph very badly slight vibration at lower speeds also know as the Chevy shake

Vehicle vibration at 45 to 65 mpg

Transmission issues: Surges forward and shifting too soon loud clunks when it shifts up and down lower gears vibration when coasting to a stop difficulty/hesitation on shifting properly on acceleration loud clunking at downshift from 3rd to 2nd gear and vise versa and also a clunk shift when the vehicle approaches a complete stop. The downshift is so hard that it is a safety concern. There is tons of complaints on the internet claiming that a plate on the 2nd gear has to much of a gap. It's a manufacture defect, GM service bulletin: #pip5175B and refers to mexican sourced transmissions that were built with the stator support bolts not being properly torqued, leading to various concerns, the first of which to show up is usually the 1-2 shift flare/slip. The kick is hard enough when it shifts that you feel like your getting rear ended from 3rd to 2nd. Also you think your transmission will drop out it goes into gear so hard.

Truck seems to have an issue when shifting gears. The truck jerks hard when it shifts ramdonly at lower speeds (5 to 25 mph) and can sometimes startled you because it makes you think that you been rear ended by another vehicle. When coming to S stop the truck has a hard time deciding which gear to be on and after you are at a complete stop just about 3 seconds later you feel a strong hit coming from the back of the truck moving the truck forward about a foot if your not pressing on the break really hard, this also happens but with more intensity after the truck has been moved in reverse and it put in drive it takes a few seconds to engage and you feel a strong jerk forward without giving it gas. Last but not least the truck shakes more than normal while in idle almost to the point where it feels like its going to shut off.

The contact owns a 2014 Chevrolet Silverado 1500. While the contact's son was driving approximately 30 mph, the vehicle lost power and vibrated. In addition, the stabilitrak warning indicator illuminated. The failure recurred numerous times. The vehicle was taken to jim browne Chevrolet (located 11300 N Florida ave, tampa, fl 33612) where the transfer case shift control module and the instrument panel cluster were reprogrammed; however, the failure recurred. The VIN was included in NHTSA campaign number: 17V414000 (steering). The manufacturer was notified of the failure and stated that a remedy part was not available for the repair. The approximate failure mileage was 35,000.

Purchased a new 2014 off the lot with 7 miles and we have had nothing but trouble with this truck. From air bag sensors going out and the dealer refusing to cover this to the seat being replaced. The rear went out and had to be replaced. The ac has been replaced twice. Both times called Chevy asking for help and was denied assistance. Seatbelt issues. Computer screen issues. Tire senor issues rattling in the dashboard. I will never own another Chevrolet product again. This is the primary vehicle my husband drives to work and back home. This truck is only 3 years old and we have actually think we have a defective product and Chevy doesn't seem to wanna help us. I hate to write the monthly note out each month paying for something that's always breaking down. I will never own another Chevrolet product.

1. driver's seat reclining mechanism jammed and stopped working. Had to have seat back frame assembly replaced just after warranty. 2. six speed transmission generally works good most of the time. On occasions (about 50 so far) when backing out of a space and shifting gear from reverse to drive, the transmission does not shift, there is a 2-3 second delay before it shifts and jumps into gear with a clunk. This causes problems when you are backing out into traffic in parking lot, onto a street, or making a 3-point turn and the transmission does not shift when you anticipate it should and you are stuck there for the delay. This could cause a crash. Took to dealer under warranty, they could not reproduce problem. Date at bottom is a guess. Have to check dealer records at home.

After a state inspection of my 2014 Chevy Silverado, I was told that the transmission cooling lines were leaking and needed to be replaced. The transmission lines had failed where the two pieces are crimped together causing the leak.

Shortly after getting my truck, I started noticing a vibration that appeared at certain speeds. I took it to the tire shop and had them computer balance, only to find that they were in balance. Called the dealer where it was purchased, and they had nothing to add.now I am hearing that many owners of this model are having the same vibration. Now I have received a letter from a group of attorneys that say that they are representing the truck owners with this problem. I really do not want to get into some legal thing. But want the vibration to go away.

At 113,000 mostly highway miles, truck started shimmering when a load was placed on it, like going up hills. Was told at Chevy dealer it was transmission. My warranty was up till 100K which was 2.5 months before this problem. I flushed transmission every 30K (way early) and local dealer said transmission should never have gone like that. GM is not wanting to help at all on a 48K cost truck and I had to pay $5150 to replace transmission. Plus out of town "being stuck" costs too.

- Martinez, GA, USA

Very noticeable vibration at 25 mph and again at 45 mph. Only seems to affect vehicle in 4 cylinder mode. Lots of internet research has found this to be a recurring problem with many Chevy Silverado 1500's as it is in mine. I have contacted GM with a complaint and they have given me case # 8-2286316021. There seems to be no fix established as of yet. But, my concern is when driving on snow, ice or wet roads, the vibration could cause a serious issue with traction. If it vibrates while on slippery road conditions then the traction is reduced causing a safety concern.

Vibration issues at different speeds between 70 to 80 mph on the highway. I had my wheels and tires rebalanced many times. Still have issues on been checked.

- Marrero, LA, USA

Vehicle exhibits vibration at speeds of 75 mph +. vibration is coming from rear of vehicle, such as rear axle. Vehicle started vibrating at approx 30K miles. Vehicle is currently at 44K. No vibration in the steering wheel. Vehicle is smooth below the threshold speed noted above.

- Tampa, FL, USA

The right rear axle seal was replaced by the dealer due to leaking at 16K miles. Vehicle now has 44K miles and the leak is back. This leak allows rear axle oil to potentially contaminate the brake pads on that wheel if left unnoticed long enough, which could lead to hindered braking power on the wheel.

Here's my story for those that will listen. I purchased the vehicle brand new and a few days later I mentioned to the salesman that it drove unusual and he replied that it could be from sitting on the lot...so I waited for the first scheduled maintenance and let them know that there was something not right with the shifting of the vehicle. I noted that it was loud clunking at downshift from 3rd to 2nd gear and also a clunk shift when the vehicle approaches a complete stop. The downshift is so hard that it is felt in the brake pedal. This is the part to me that raises the safety concern. The response was that they checked it and that everything was normal. I was informed that it should get smoother as it break in. They went on to say if I bring the vehicle in for the same issue and nothing is found that I would have to pay a diagnostic fee. So now at approx. 20,000 miles and I contacted General Motors. They agreed for more diagnostic and now there is a technical service bulletin that states that it is a normal characteristic of the vehicle. Now the vehicle has feels like it got worse and drives terrible and unsafe. Meanwhile there are complaints about this same problem on the internet and nobody has done anything about it. It's funny that 2016 Silverado is the same truck but without the problem. GM needs to make good on their productions mistake and support there product. Silverado drivers experiencing the same condition should complain to make manufacturers responsible. Please investigate!!!!!!!!!!!!
