I have had this issues happen numerous times. The first I was backing up into a parking spot and my service stabilitrak warning came on, and my steering wheel started jerking left and right on its own. 2nd time I was pulling into my parents drive way and warning came on while turning causing truck to jerk and I almost hit the corner of the house. A 3rd time happened again reversing but this time my headlights dimmed and I had multiple service warnings pop up. A 4th time I was again about to reverse. I was able to straighten up and while in reverse and foot on brake, I would turn steering wheel and it would jerk back to center on its own. I took video of that accurance. While driving on the highway yesterday night. I noticed my headlights kept going dim then bright. While in cruise control going 75mph I moved left to pass a vehicle, when I turned right signal on to come back to lane my cruise disengaged. This happend 5 times. Before one of the occurrences while in cruise I tapped the brake to slow down, and my volt gauge dropped to 10 or so and the headlights almlst shut off and all lights in cab flikered on and off. It almost felt like the truck was about to turn off but didn't. last issue, a few times I have tried to start the truck and the anti theft deterant comes on and I have to try numeros times to get truck to start.

The contact owns a 2014 Chevrolet Silverado. The contact stated that while driving approximately 55 mph, the steering wheel seized. In addition, the vehicle stalled. After several attempts, the vehicle was able to restart and the steering warning light illuminated. The vehicle was taken to the dealer, who diagnosed that the anti- theft module and the steer-assist needed to be reprogrammed. The vehicle was repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 78,000. Updated 04/08/16

While driving my 2014 Chevy Silverado, I have had 3 instances where the stability control light came on and I suddenly lost lost all steering and brakes. Within a 2-3 seconds the cluster and radio went dead and then the engine stopped. I had no ability to control the vehicle. I took the vehicle to the dealer and they stated the logs showed 1 1/2 pages of vehicle communications errors including loss of communications to steering, loss of communications to brakes, etc. After 8 days of analysis, the dealer notified me that this was a known issue with GM and that there is an active pi number for the issue. However, there is no known resolution for the issue. Because there is no known solution, they asked me to come pick up the vehicle and continue driving it and they will contact me when a solution is found. When I asked if they understood that I could lose control of the vehicle and potential kill myself, a family member of another driver they only told me that they had no other suggestions. I escalated to GM customer care and they assured me that because there are no open recalls on my vehicle for this issue, it was completely safe to drive and that I shouldn't worry. A search of the internet revealed many people who have had the exact same experience and who were told to continue driving the vehicle. One even stated that they hit a pedestrian after losing control of the truck. This issue is obviously a huge safety risk as the driver can lose complete control of the vehicle at any speed.

- Underwood, WA, USA

Electric power steering failed while driving. Truck towed to a dealer. After replacing the electric power steering motor, electrical loom and the battery, was informed that the steering rack failed - possibly due to water penetration into the rack and pinion drive. Suspect a faulty or badly designed seal which may be the cause for thie failures on the 2014 Silverado trucks

While driving about 30 mph. Turned the indicator and was going to turn right into a side street.. a warning appeared on my dash "power steering need service". lost power steering and was lucky to stop before the turning and not hit a car on the side street.

The vehicle has an established, measureable and documented vibration problem that randomly increases & decreases in applitude & frequency at all speeds. GM is unable to resolve after 12 dealer attempts to address, including multiple sets of tires, rear differential, drive shafts and shock absorbers all failing to resolve the issue. GM stated vibration is inherent to the design and no further action needed or will be taken ever for vibration, regardless of circumstance. Such a vibration is a significant safety defect because it is essentially like cutting wires to warning tell-tales by removing a driver's ability to discern tire/suspension/powertrain/steering problems that can only be identified by feeling a vibration (such as a loose wheel or damaged suspsension components) prior to a catastrophic event, especially at high speeds. Not only for the vehicle occupants, but also for any road user when it results in the driver loosing control of the vehicle. GM's own attempts to fix the vehicle with the list of parts above irrefutably supports the inability for a driver to identify the source of a vibration. If experienced technicians and subsequent corporate engineers cannot recognize the vibration as being different from wheels, suspension, powertrain; then a normal driver will have no such warnings available should a potentially catastrophic safety issue be present. Further, since GM refuses to address any further vibration issues with this vehcile, it is like have a airbag warning tell-tale continuously illuminated whether or not a problem exists & GM stating to just live with it. In other words, if I get a loose wheel, I guess GM figures I will know it when it falls off. In addition, to safety defect described above, the vibration is an extreme source of driver distraction & driver rage as attempts are made to produce and/or reduce the vibration while driving.

We own a 2014 Chevrolet Silverado 1500. Upon traveling a low rate of speed or under 40 mph, there is a sudden loss of power. The vehicle hesitates numerous times and stalled. The vehicle shuts off and there is a loss of power and engine dies. The vehicle was taken to the dealer more than twice, but they were unable to replicate and diagnose the failure. The approximate failure mileage is 35,024.

When the below messages are received, steering the vehicle is extremely difficult, the steering wheel thrashes back and forth (when at slower speeds - I.e. attempting to park) and usually enters a "low power mode" where you can't accelerate, steer or about anything. In all cases, turning off the vehicle and restarting seems to return to normal until it happens again. 9/6/15: While making a turn, received a "stabilitrak off" and "power steering assist reduces drive with care" 9/8/15; received the above two messages plus "service 4WD" - 9/10/15 dealer replaced the transfer case actuator per tsb 9/14/15: Received stabilitrak and pwr steering messages when attempting to park the truck -- dealer stated love voltage codes present, so they charged the batter and returned the truck to me. 9/16/15: Had the steering wheel thrashing when backing into my driveway, but no messages 9/24/15: While on the highway (lucky traffic was slow) received the stabilitrak (twice) and pwr steering messages, so I exited to take side streets home. When making a left turn received the stabilitrak and pwr steering message, the low power mode and thrashing steering. This occurrence was in traffic and dangerous. Currently at dealer, they state they are replacing both positive and negative cables and rerouted a wire that may have been rubbing the frame. Note: There is a recall on the 2015 models for the electric power steering (eps) GM # 14743 -- same symptoms...

I purchased the vehicle, brand new in may of 2014. The first malfunction of the vehicle was June 19 2014. The steering wheel, ignition, and cylinder remained locked and I was restrained from starting vehicle I contacted Chevrolet roadside assistance in which they were no assistance.I was able to start car after aprox 30min. The second malfunction was in March 2015. My truck turned off while driving on the freeway in the fast lane causing loss of power steering, speed and all functions of the vehicle. Onstar and highway patrol were contacted and highway patrol assisted in pushing vehicle to the shoulder. The third incident was July 30. Immediately after taking my truck into paradise Chevrolet for an oil change. A gas attendee noticed I was leaking oil. The oil cap had not been tightened causing oil leakage. The most recent event was August 11,2015. My vehicle turned off once again while being driven on the highway with my husband and five month old daughter in it, causing loss of power steering, speed and all functions of the truck. The vehicle did restart aprox.20min after.however, when restarted the truck made a noticeably shakey motion. Both events in which the vehicle turned off while driving were followed shortly after paradise Chevrolet of ventura ca "upgraded software", without my knowledge. Both times I went in for an oil change and I was informed after the fact that they had upgraded software/ preformed a "recall".

At highway speeds (above 50 mph) after driving for 20 minutes to 1/2 hr, a slight turn to the left (at speed) causes the steering to stick/bind. It may be a loss of power steering assist. This happens intermittently. This prevents the wheel from returning to center from the left turn. The resistance can be overcome by increasing to force applied to either return the wheel to center or to increase the left turn. Update 9/15/15

While driving down the highway a stabilization control light came on briefly, then went away. Approximately 5 miles later after exiting the highway, and going down a side street, the truck died and the steering wheel locked when I slowed and started to make a right hand turn into a parking lot. This has since occurred once more under similar conditions while slowing, braking and turning at low speeds and not under throttle.

When driving truck on interstate I notice a vibration in the front steering and wheels once the truck goes over 65 miles per hour. This was doing it just after 1000 miles.. when the rotated tires when truck was serviced. The issue is still there

- Portland, ME, USA

Since about 15000-18000 miles this truck vibrates at most speeds, most noticeable at 65 mph and over. It is at the dealer for the second time. The first time all they did was balance the tires, but the problem didn't go away. The dealer is still scratching their heads on this. The loaner 2015 I have is worse and vibrates at all speeds.....
