Truck was took to GM shop for vibration in power train replaced rear propeller shaft. I drove truck 60 miles home same vibration took back to shop. Took inst. Tec. And transmission tec. For ride both said yes you have a vibration and a hard up and down shift at 20 to 30 mph. Nothing done at this time called shop foreman and he said would get field engineer involved not heard from them since. Filed a complaint with GM case # 71-1359113487 have not herd from them. Vibration has got worse it will vibrate at any constant speed from 0 to 60 along with a rumbling sound plus the hard down and up shift. 7117 miles on truck now I feel it is getting unsafe to drive. For if it locks up going down the road at 60 mph in heavy traffic what is going to happen am I going to keep it under control.

I started hearing some ticking. And no big deal the next day the motor just vibrated and them stopped accelerating, started rattling. Freaked me out big time, I've only had the vehicle for about 2 months. I'm no mechanic, but this ain't normal. I fear the worst.

Since I purchased this vehicle is has had a vibration from 5-20, 40-50, and 68-78. It has been in the service department 4 times for this problem alone with no resolution. General Motors understands their is an issue with this model truck but does not have a solution. The vibration is felt in the seat, the gas pedal, the steering wheel and the rest of the truck. Tires were indexed, rotated, and balanced, along with the drive line specifications inspected and were found within normal limits even thought vibration persists. Other issues I have had were the exhaust squeaking noises when transferring from V8/V4 mode, in which the entire exhaust system was replaced, water leaking from the sunroof and windshield, frame coating peeling off causing the frame to rust, the seat frame shifting, moving and clicking when turning the vehicle, hd radio loses signal intermittently, radio and HVAC knobs were not lit, headlights were misaligned from the factory, and 4 other recalls such as, overheated exhaust components, unwanted transfer case shift to neutral, peek in odometer display incorrect, and transmission oil cooler connections possibly being bad. This vehicle currently has 6500 miles and has been in the service department a total of 30 days so far.

I'm really disappointed in how my truck is rusting. It has the amount of rust that I would expect to see on a truck after 7 - 10 years. The truck's underbody including the frame is rusting everywhere. For a truck that has only 6,000 miles on it this is ridiculous. Whatever was sprayed on the frame is just peeling off in chunks. I had the dealership in anoka, main motors look at this when I got an oil change today and they agreed the rust is excessive but GM has told them to do nothing about it based on pi0281D. GM claims this is supposed to be the most rust resistant truck ever.

The vehicle is shaking on the highway at normal highway speeds. It makes for poor control of the vehicle. It is a brand new Chevrolet Silverado high country. It has been serviced 3 times and the drivetrain has been balanced, the tires replaced, forced balanced the wheels, replaced the tires and still the problem persists. It causes lane wander and does not feel safe at normal speed.

On Friday May 23, 2014, I was backing an empty boat trailer down my private boat launch with my new 2014 Chevrolet Silverado 1500 pickup. When I put the transmission into reverse with my foot on the brake the engine suddenly revved up, started spinning wheels, and shot down the ramp hitting three bulkhead pilings eight feet apart, finally wedging the truck into the last piling and stopping before going into the water. The incident lasted less than five seconds and my foot never left the brake as witnessed by a third party verifying the brake lights never went off. I feel obligated to report this to both Chevrolet and the National Highway Traffic Safety Administration. Had this occurred in a public parking area, serious injuries and damage to other vehicles could have resulted. An insurance claim has been made, and after repairs have been completed, the vehicle will be taken to my Chevrolet dealer for analysis for possible defects.

Was in a turn lane following a vehicle going slightly uphill rolling up to an intersection to make a left. The vehicle in front of me made their turn and while I was still rolling I checked oncoming traffic. There was a vehicle coming in the other direction, but I too had time to make the turn in front of the oncoming vehicle. I stepped on the accelerator and it did nothing for what seemed like a half of a second before finally accelerating. It was as if it was the old days when we had a badly tuned carburetor and the engine bogged before finally taking off. Only, the truck doesn't bog, it just doesn't respond as quickly as it should all the time. I had the vehicle in "drive" so perhaps it was running in V4 and/or in the middle of a transmission shift or downshift. Regardless, an accelerator that does not respond the same way every time but varies depending on driving conditions is in my opinion dangerous.
