Within 6 weeks I had to replace 3 tires on my truck. I still had 4/32 of were left on these tires that only had approximately 27000 miles on them. I ended up buying a forth tires and had the tires balanced for another hundred dollars.I have all the receipts and I am looking for compensation for inferior tires that were on the truck when I bought it. Chevrolet quality was not there on my tires. This happened over a 6 week period starting 10/20/2017 to 10/28/2017.

Brake pedal gets very hard when driving at slow speeds and in reverse. Makes a ticking sound like the anti lock brakes are kicking in but no dash lights illuminate. Almost rear ended a vehicle travelling 25mph but was able to pull in a parking lot to avoid collision. Truck has 79xxx miles

Truck vibrating at highway speeds. Between 65 to 85 mph the tucks has a constant vibration.

My truck only has 42,000 miles on it. Over the course of 3 days I noticed the air conditioner go from blowing cold air to blowing warmer air until it no longer was cold. The dealer inspected the system and said the ac condenser needs to be replaced. Since it is out of warranty, it will cost approximately $1,300 to fix. The part is on backorder for at least 3 weeks. The current "feel like" temperature in Florida is 106 degrees Fahrenheit outside. That would be a long time to go without A/C without a loaner from the dealer, which the dealer did offer.

At approximately 45K miles, truck began to shake at 70 mph. Issue only occurs on highways/interstates where 70mph can be driven safely. Now has 52K miles. Dealer had accessorized truck with oversize wheels/tires & lift kit. I bought it this way. Was smooth until about 45K miles. My tires are still good, but I will replace before 60K miles internet searching revealed much information regarding "Chevy shake" issue with GM full size trucks and SUV's. I believe mine is affected by the 'Chevy shake' mystery problem. Will be taking to dealer for regular service 7/21/17 and advising them of this issue. They will likely blame it on aftermarket equipment/suspension/wheels/tires, even though the dealership accessorized the truck when new through a specialty shop. I bought warranties that supposedly cover all of the truck, even the stuff dealer had the specialty shop put on it.

While using a spare key to my 2015 Silverado for the entire day, and driving over 70 miles, the "anti-theft" warning light suddenly came on. I continued to drive approx. 10 miles with the light on and while turning off a busy road, across on-coming traffic, the truck completely shut off. No steering, no forward movement, nothing. It virtually went dead! I was able to put the truck in park and try to start it again (thank goodness no traffic coming through at the time). After several attempts it started again and I began to drive around the corner to my home, where it completely shut off again, in front of my driveway. Had it towed, as I was nervous about driving it again. The Chevy dealership service department was unable to conclude what happened. They tested it with the spare key, and still no sign of any trouble. I am reluctant to drive this truck.

The 2015 Chevrolet Silverado K1500 high country vibrates and makes a loud humming noise at various speeds beginning at 20 mph up to approximately 60 mph. The vibration can be felt through the seat and steering wheel. The frequency and sound level is not dependent on speed, load or road conditions. It's always there. I'm taking it back to the Chevrolet dealer again tomorrow for another round of attempted repairs. At first the dealer said the vibration and noise was normal. After showing them a copy of the GM service bulletin ' pi1354C, they now admit to a potential issue. Still not solution.

Air conditioner started blowing hot air. Took to dealer they found a weld broken loose on the top left corner of the condenser causing a leak. Currently GM condensers are on back order. Due to the overwhelming problem nationwide. They charge me to refill the system with freon (or equivalent), 24 hours later it has leaked out and is blowing hot air again. Dealer guessed 3 to 6 weeks before they would get the replacement part in. Truck has 68,000 miles with cost going to be $1300. We also have a 2015 Chevrolet Suburban with 74,000 miles on it that had the exact same problem. Cost $1300 to fix.

Truck shakes while traveling on the highway. It isn't noticeable on side streets in the city but when traveling on a major highway the entire truck shakes sometimes at lower speeds but always above 70-75 miles per hour. It shakes so violently that a drink in the console will shake out of it's container. I've had it in the shop 4 times but the Chevrolet service center cannot fix it. They have balanced and replaced tires but cannot fix it. I feel it is unsafe or could lead to damage rendering it unsafe.

Vehicle has bad vibration between 65 and 75 mph.

I bought a GM certified Silverado with 20000 mile on it. And the idle vibration and drive vibration are so bad it gives me headaches after driving for any period over an hour. The dealer says this is normal and they are nuts if this is normal. I have contacted Chevrolet. But after researching online, there does not seem to be a fix. My truck is unsafe! Chevrolet needs you fix these problems.

I own a gray 2015 Silverado and the paint is flaking off on numerous spots all over the vehicle. The flakes are the size of a pin head and appear to be mainly around the grill and front of the vehicle.

My truck had approximately 10 miles when I purchased it in Dec 2014 and has been in the shop pretty much ever since. Immediately after purchasing the vehicle, I felt a very substantial vibration around 76+ mph. Initially, 2 tires were replaced and balanced; that did not correct the problem. Then the dealership indicated that GM said I have to put 500lbs in the back of the truck and the vibration will stop; this is not even remotely practical. Subsequently, the tires have been rotated and force balanced several times throughout the past 2 yrs. In June 2016, the dealership stated the problem was that the tires were mounted on the rims incorrectly and replaced all four tires and balanced them; the vibration continued. After trying to schedule another appointment with the dealership over the same issue, they will no longer call me back. I have attempted to schedule an appointment at least 8 times within the past month to no avail. Several people have indicated the problem is quite possibly the drive shaft B/C the entire truck vibrates while driving down the road. Therefore, I took my vehicle to another dealership where they told me I need to rotate and balance the tires. After discussing the history of the truck with them and requested the service dept. Check the drive shaft, they stated the service manager said it is not the drive shaft (which was not inspected to my knowledge) and told me the tires need to be forced balanced and they could not help me. This dealership referred me to another dealership for assistance. I have been fighting this issue for almost 2 years now and cannot get help. Further, neither of the dealerships have made me aware of the bulletin and have not tried anything past the replacing & balancing the tires. The vibration is so bad other things in my truck are starting to come loose and vibrate.

Purchased new 2015 Chevrolet Silverado 1500 in January of 2016. Experienced a vibration at all speeds from the very beginning of purchase. Vibration gets worse at higher speeds. Vehicle came with steel wheels from the factory. Vibration can be felt in the seat and seen in the center console. Vibration is coming from rear of vehicle. Replaced wheels and tires with aftermarkets. The aftermarkets were bigger and heavier and made vibration extremely worse. After assuring that I wasn't dealing with a problem with the new wheels and tires, I put the factories back on and took the vehicle to dealership and reported the problem. The vehicle was in the shop for 3 1/2 months. The vehicle failed pico scope tests. They put several new tires on the vehicle, changed both rear axles, and changed ring and pinion in rear end. These steps helped reduce the vibration, but did not totally resolve the issue. They then decided to put aluminum wheels on the truck, which helped reduce the vibration down to barely noticeable. My concern is by putting the lighter wheel on the vehicle to reduce the vibration, they are only masking the problem, since the heavier the wheel/tire assembly, the worse the vibration. They are telling me they do not have to do anything else to the vehicle. General Motors has told me they are not going to pursue the issue any further. They tell me they know there is an issue but not sure what it is and since it is not a safety issue they have honored the warranty. How do they know that it's not a safety issue if they don't know what the problem is. I believe they know exactly what the problem is and they are passing it on to the consumer. There was no disclosure of the issues with these trucks upon purchase. I do not feel safe in this truck and fear future problems with the issue. Also, the truck on several occasions has down shifted abnormally causing rpms to rise.

It has a shake that is making me nauseous and sometimes feeling dizzy. Very noticeable 65 ~ 75 mph since new

The transmission hesitates when shifting in automatic but when in manual mode it shifts fine with no issues. This has been a on going issue and problem the service center for a local dealership can not find the issue. But there is something going on with the transmission.

Vehicle was in four when drive low stopped and got out to open a gate heard a lou pop looked back it was rolling backwards went about 200 feet with a trailer hooked to it the trailer flipped around hit the side of the truck made another loud sound and it stopped. We are being told nothing is wrong with it. Another time had it in low four when drive and it kept rolling in park. The vehicle was parked. And when we got to it the gear shift was still in park.

I am concerned about the excessive shaking/vibration in this 2015 Chevy Silverado and, thus far, GM customer service and the dealership have no resolution in sight. The problem has been occuring at highway speeds (most notable above 73 mph) since the truck was purchased Aug 2015. As they can't identify the cause of the problem, I can't be sure the origin is or is not a safety-reated concern. The dealership has balanced, re-balanced, rotated, and road pressure tested tires to no avail. Even tried a new set of tires off of a 2016 model to no avail. As this matter continues and doesn't appear to be tire-related, I'm worried that the issue may be in the suspension and will, at some point, cause or create a catastrophic failure.

The truck has a constant vibration at highway speeds. Two different dealers have verified the problem, GM field engineers verified there is an issue, and the engineer recommended the dealer change rear end parts, still no fix. Two different dealers felt roadforce balancing the tires would help; it has not. The truck also makes a chirping noise when transitioning from 4 cylinders back to 8 cylinders.
