I was driving on the interstate at about 50mph when a stabilitrak message came up. After it came up the vehicle completely shut down for a couple seconds. I lost all steering and braking during this time as if the ignition was turned off. This happened a couple of times. When I got to my destination the vehicle completely shut down before I could put it into park and turn the ignition off. It is extremely concerning that the vehicle was doing this while driving at highway speeds.

Numerous occasions this vehicle will have issues when turning? on 5 different occasions this vehicle while in motion on a highway will suddenly turn off completely on its own and then suddenly turn back on after I release the steering wheel. This has happened while driving 75mph on hwy I-35 while I was changing lanes.

At slow speeds (mostly when turning) power steering will go out. I've had 3 instances where the truck completely shut off and just as many where it felt like it was about to shut off. Other symptoms have been while driving on highway, generally on a longer trip, warnings about stabiltrack needing service come on, my lane departure sensor will automatically switch from vibrate to audible beep, dimming my headlights or turning my turn signal on will cancel cruise control. I had the recall for software fix for power steering issues applied in September 2017 where previously I experienced none of these issues. All of these issues have been after the recall software fix was applied. The dealer says it's due to a film that builds up on the battery cable connection and causes it to not have a good connection with the battery. Apparently there is a bulletin out for this issue but it isn't a recall so dealers are charging around $700 to fix this. Having your truck turn off while driving is a clear safety issue and one that is much worse than the recall for having your power steering go out when turning at slow speeds.

The contact owns a 2014 Chevrolet Silverado 1500. The contact stated that the vehicle stalled several times without warning. The contact took the vehicle to several dealers including ourisman Chevrolet of bowie (16610 governor bridge rd, bowie, md 20716, (301) 262-7600), jack winegardner Chevrolet (11001 indian head hwy, fort Washington, md 20744), and ourisman Chevrolet of rockville (807 rockville pike, rockville, md 20852, (301) 637-6496), but the failure could not be replicated and diagnosed. The contact was uncertain if the failure was related to NHTSA campaign number: 14V614000 (electrical system) pertaining to the battery being drained and potential contamination of the chassis electronic module. The three dealers had not test driven the vehicle. The manufacturer was notified. The contact was waiting on a response to determine if they could provide a permanent remedy. The vehicle was not repaired. The approximate failure mileage was 90,000.

This is a complaint on a 2014 Chevy Silverado truck which we purchased new and has only had one driver. It will randomly loss power going down the highway. Also, frequently now, losses power steering and will violently jerk making it uncontrollably. Had the truck in the shop at the dealer where we purchased it 2 years ago and they could not find the problem. There was a recall on the power steering. We took the truck in to the shop for the recall but are still having the exact same issue. This is a safety issue, not a warranty issue and the dealer is wanting to charge for the diagnostic and any repairs, stating the truck is out of warranty.

When turning into parking lot today at low speed, electrical system went crazy, screen flashed power steering failure, stabilitrac failure, doors locked and unlocked and engine died. Restarted and was fine driving forward and repeated failures again when turning to park in parking space. It is fortunate this was in a parking lot and not on interstate or other main road or while turning at a traffic light. There was a recall in fall of 2017 for power steering that was repaired at dealership upon notification. When I contacted the dealership, the service department supervisor advised it sounded as if there was a poor connection of a battery cable. The battery was replaced just a few months ago. It seems to me that if a it's a battery cable connection issue, then GM has another safety problem they need to address since I've read numerous other complaints with the exact same issues, and in my opinion, there must be a manufacturer defect if battery cables just come loose for no apparent reason. This needs to be fixed before someone is very seriously injured or killed as a result of this dangerous condition. GM seems to be aware of the other reported issues and has taken no measures to correct it. Maybe all of us who own their vehicles should file a class action lawsuit and they might get off their [xxx] and do something! I certainly won't hesitate to file a civil complaint for product liability if a family member is hurt as a result of their continued negligence.

While conducting low speed manuveurs radio and dash flashes off, then engine shuts off while vehicle is still in drive causing loss of steering assist and brake assistance. Dash and radio turn back on and warning messages stating stabilitrak disabled, steering assistance reduced, 2 keys programmed, open and close drivers window, and park assist disabled are displayed. Dealership thinks this could be due to corrosion in the power distribution box and recommended replacement.

While driving my 2014 Chevy Silverado at any speed it will automatically shut off while turning completely disabling the engine, this also happens at any speed sometimes the vehicle will start and sometimes vehicle won't for several minutes I wish GM would recall this vehicle that I have only owned for 2 months before someone gets killed I bought it from phil long Ford in Colorado springs, I have taken it to the dealer and they can't seem to find any issues wrong with the vehicle they've had my truck for several days and I don't see them finding any answers

While driving down the road and turning the steering wheel, the steering wheel snatches away from your hand. When doing so, the locks unlock and lock, then the stabilitrack light comes on. This has happened several times and twice the vehicle completely shut off. Luckily my wife was turning into the driveway when it did because it shut off and the steering wheel locked. She is scared to death to drive this vehicle and I owe way too much money to trade it in. I've taken it to my dealership here and they tried reprogramming it due to a recall but that did not fix it. When I called to ask for assistance, they replied that it would be a minimum of 1 1/2 hour labor to diagnose it and that it $110 an hour. I've noticed while looking on the internet that this is a common problem with the year model truck. This is a major safety factor and needs to be addressed asap before something happens to one of my family members. People on the internet state that it is a grounding problem and the manufacturer knows about the problem.

- New Braunfels, TX, USA

My 2014 Chevrolet Silverado is at a GM dealership for the 4th time due to complete electrical and engine shutdown while driving. The issue started during low speed sharp turns but now is happening while driving the vehicle straight. Complete loss of use occurs and the vehicle will not come back on for 10 minutes after the occurrence. Power steering recall has not resolved it, ground wire tightening has not resolved and main battery cable replacement has not resolved. Dealership response is they don't know what the issue is caused from. I am very concerned this complete loss of power while driving will cause a severe collision and no recall or resolution has been created by GM.

The service theft deterrent system warning came up on my dashboard and the vehicle wouldn't start. Removing the key and opening the door reset it. This happened Friday, March 30th. On Sunday April 1st, a similar event occurred, except this time, after getting the car started I drove about 1/4 mile and the vehicle lost all brake/steering support and then the engine cut off, leaving me to try bringing the vehicle to a stop myself (which thankfully I did). I took the vehicle to the dealership first thing on Monday, April 2nd, and they ran tests and found a service bulletin saying to replace the negative battery cable and the junction box. Being a service bulletin only though, it is not covered by the powertrain warranty and would cost $675. Being that this is a safety issue since it cuts all power while someone is driving, I feel this to be unfair.

The stabilitytrack will flash on and make the steering wheel very difficult to steer or while turning the steering wheel will jerk out of my hand and not let me maneuver the way I want to. At the same time the truck will briefly lose all power disabling everything. This has happened in parking lots as well as everyday city and highway driving and at all speeds from as slow as 5mph to as fast as 70mph. There has 2 times after this happens that I turn the truck off to try to restart it, the truck will be completely dead. Not even the hazard lights will come on. There are other times where I will lose all power to my radio and driver info center and it stays black until I restart the truck a few times. I have taken it to the dealership now 4 separate times now and every time they say its something new. I have paid a little over $800 so far and it is still happening. I am now waiting to hear back from GM/Chevy to see what they can do, but looking at what I have already dealt with it I am not optimistic. I have read other complaints about this and I am afraid that its only a matter of time that I will not be able to recover my steering and I will get in an accident with my family in the truck.

Truck dash will flicker and cause stabletrak to disable, and then steering assist says limited. Radio will change stations when this happens, and the steering wheel will lock up and is unable to be turned. Has happened several times while we're on the highway. It's when we're in motion, has happened while trying to park, going on a back road, and on the highway. While in park, we can hear occasional clicking coming from inside the dash. It's been occurring since October, but was really bad on December 22nd. Have a video of one of the occurrences, but not sure how to upload it.
