Truck began to have the Chevy shakes about the 12K mile point and has increasingly gotten worse the more mileage the truck gains ( currently 14K miles) I have called and talked to technicians about this and they ensured me that its normal. I've owned several trucks and I have never not been able to go over speeds of 55 without having terrible shakes and wobbles in my truck. Chevrolet needs to address this properly and fix the issue or buy back the trucks that are affected by this issue, when a person spends 50K + on a vehicle this should be the last thing the should have to worry about is feeling safe in their vehicle. I will never buy another Chevrolet product again due to not only this but a number of other issues I have with the truck including hard shifting and extreme lack of power.

The contact owns a 2015 Chevrolet Silverado 1500. While driving approximately 35 mph, the electronic power steering assist failed without warning. The contact was unable to activate the power steering assist. The contact took the vehicle to the dealer where it was diagnosed that the power steering failed and the power steering electrical motor needed to be replaced. The vehicle was repaired; however, the failure recurred. The manufacturer was made aware of the failure and informed the contact that the failure was considered an elemental failure. The contact was referred to NHTSA. The approximate failure mileage was 70,000.

I bought the car three days earlier. The vehicle has 4800 miles on it. It is a certified used truck. I was driving on a curvy road on the side of a small mountain. While driving, I noticed the steering getting a little play in it, not much ever so slight. When I got to the 90 degree left turn, onto another road, I found I had lost the ability to turn the vehicle. The truck started toward the trees. I hit the brakes and gave it all I had, muscle wise, in order to make the turn. I pulled over and regained my com-posher. I did notice there was a message on the instrument panel indicating a problem with the steering and to be careful driving, I did not notice that message before the incident. I then proceeded to drive to to the dealership very slowly with the flashers on. I only had to make five turns and eight miles to go to the dealership. The steering was making all kinds of noises and jerky motions. There was no injuries or damage done to the vehicle during this incident. I just wonder what would have happen if my wife or one of my daughters were driving.

My Silverado has developed a vibration around 4-5000 miles from new. The vibration starts around 60mph and increases in intensity up to and beyond 80mph, the legal speed limit in Texas. The vibration can be felt throughout the cabin in the seats, center console, steering wheel, doors and gas pedal. On my last 3+ hour drive I had to stop midway because the vibrations gave me a headache. That's never happened in any other vehicle ever. After 3 visits to the dealer and multiple road force balance and tire replacements later the dealer states the truck is operating normal and is in spec. This is unacceptable for a brand new vehicle and I'm working on taking it to the next level with GM to deal with the problem.

The trucks have a vibration that is felt in the steering wheel, floor, seats, accelerator and brake pedals etc. While driving. The major consensus it that the worst speed it 76 mph, yet it is felt to a lesser degree at any speeds, with some being worse than others. There are a large number of trucks with this issue, yet General Motors refuses to do anything about it. It began within a couple weeks of purchasing my truck. I found people first reporting the issue in 2015, and more recently it continues with the 2015 and 2016 model years.

I was involved in an accident on 1/15/16 in which I was sideswiped by another vehicle. Upon impact, I had no brakes and no steering control. This caused me to rear end another vehicle and hit a tree head on. The airbags never deployed. I was unable to stop the vehicle or control it. I could have been killed or killed someone else. I am very concerned. I have had the truck in the shop on several occasions with electrical issues, yet the dealership could not find anything or it was minor corrections. I have been very concerned with the electronics of this vehicle since I bought the truck in August 2015. The insurance company totaled the truck.

Ignition switch and key came out of steering column while driving. When I pulled off road and parked, the ignition switch internals and key came off in my hand. Not able to shut engine off. Called onstar, they could not shut off engine. Truck was flatbedded to dealer while still running. Risk of steering wheel locking causing loss of control. Steering wheel makes clattering noise not connected to wheels at times. Instruments dimming and flashing when turning wheel at times

After parking and removing key steering wheel disconnects from front wheels, makes a rattling noise as if some metallic part is loose and then then jams, making it difficult to rotate ignition key to start truck again. Other times power steering assist is lost and truck is difficult to steer.

Use this truck for commercial purposes to haul trailers. Truck has turned off while driving 4 times. Three while driving with trailer when it hits rough road or under construction road and takes hard jolt to front end. First you are driving, then you hit bump or dip in road and you notice you have no steering, when you look down you notice whole display is shut down ( like it was never on) with no warning lights displayed. You have to put truck into neutral while driving and restart. Last time it happened had 30 foot trailer on truck and were in a downhill position with a turn and no steering capability ( no antilock or trailer brakes because they need electricity to operate)and 300 ft from going off embankment and then dropping 100ft into a gully. The trucks whole electrical system turns off shutting down everything in the truck. Own 7 trucks and have owned 20 plus trucks over the years. I have had design flaw issues and just fluke issues that just happen to that one truck. This really seems more like a design flaw, either in ignition with their new keys ( have a 2012, this ignition is defiantly different) or the electrical system, or maybe they added some sensor that shuts truck off if in a front end impact. If I am right this will kill someone, the truck gives you no warning before turning off and most people are unaware they can shift a car into neutral and restart while driving and since it has happened while pulling trailers this is very dangerous not just for the driver and passages of the vehicle but every other car or truck on the roadway with it. Example of this, the last time when we could not steer and could not go with the turn of the road, there was a car in the second lane and the trailer went into that lane, the car had to make evasive manuviers to avoid impact with trailer.

While driving at high way speed ( 70 mph posted limit ) and making a right hand long sweeping turn the trucks steering would stick or lock in the turn position. This condition would require a me to force the steering wheel back to center. At this time the condition only presents its self during highway speeds and long gradual right hand turns. This happend 6 or 8 times on my 800 miles trip. The dealer can not replicate this issue and as a result will not agree to repalce any steering components at this time. A quick internet search indicates many others have this same steering issue with their 2015 Silverado with eps steering and their dealers are alos unable to repair the problem. If this was an issue at parking lot speed I may not even care but at 70mph then it happens it gets your attention very fast. I called Chevrolet customer service and they claim no report of such an issue. As a result I wanted to at least report the issue so it is a matter of record.

New truck, 15372 miles, no off roading or rough surface driving. Pulls to the right. Concerned about suspension/steering failure. The vehicle pulls to the right. Two Chevy dealers have looked at the issue with negative results. There is no reason other than manufacturing error that would cause the problem. Both Chevy dealers have reported that the tires are in good condition and one did an alignment. The alignment, I paid for, did not resolve the issue. I am concerned because I use the vehicle to pull a travel trailer as it is designed for. Chevy, in my opinion, is not responsive to my concerns. I am concerned about loosing the ability to control/steer the vehicle if the unidentified issue is not discovered or resolved by Chevy. I propose that defective parts, or tires have been used on the vehicle when built and they are failing. Sincerely the consumer stated the vehicle pulled the right. Updated 10/15/15

The contact owns a 2015 Chevrolet Silverado. While driving 25 mph, the steering wheel shook violently and the brake pedal vibrated. The failure recurred numerous times. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 5,000.

When shifting the vehicle out of park, if the tilt steering wheel is in the full up position, and the shift lever is pulled fully rearward so as to shift out of park, then the shift lever will hit and be stopped from moving by the ignition key. If you force the situation by pulling back and down with more than normal force, the key and key switch takes quite an abnormal load from the shift lever. I reported this to the local dealer and was told that this is normal, because someone else had reported the same problem. This is not normal. There is an easy solution to this problem. The handle part of the ignition key needs to be shorter. If this situation is not fixed, I fear that the ignition key switch assembly will eventually take damage.
