When turning 30 mph and under the eps (power steering) cuts out randomly for a second or less and jerks the wheel only causing a slight swerve so far but has me worried and I'll be paying for the software update out of pocket since my truck isn't in the recall even though other 2014 sierras are recalled.

After driving vehicle for about 40 mins from last parked location, i slowed to take a left hand turn, engaged blinker, accelerated while proceeding to turn left. the steering wheel jerked to the Right and sounded an audible "ding" and door locks engaged. upon driving an additional estimated 100 feet, the entire system shut down. (i happened to be turning into a parking lot where there was a car parts store in town) no power at all, nothing on the display panel, all doors remained locked and i was locked inside the vehicle. i placed the gear shift into Park and tried unlocking the doors, which would not unlock due to no power. taking the key out of the ignition and reinserting it and tried to start did nothing. after a few more failed attempts, the interior lights and display screen flashed (glitchy blinking) and after a few more attempts, when the key was turned to the run position I finally had normal power. the doors finally unlocked. seemed as if the system rebooted itself and i had power and was able to start the vehicle. the dash panel showed a message to roll down the drivers side window, then showed a message to roll up the drivers side window. after i followed the prompts, everything returned to normal. i went into the parts store and had them hook up to a code scanner, which did not show any codes, the battery, alternator, and starter were also checked and were fine. i was able to drive home with no problem. I am afraid to drive my truck because i do not want this to happen when driving at a higher rate of speed. I was fortunate to be turning into a parking lot when the event happened. I am fearful of this happening again and causing an accident.

I-??m having a trail break system warning every few minutes. It is constant and beeps consistently. To the point where I almost cannot drive it. It won-??t go away after a little while and is constantly turning on and off. This just recently occurred and hasn-??t stopped since. Likewise there was no other indication of this happening till about two days ago. It-??s very distracting and persistent to the point where I feel like I can-??t even drive with it on.

While fixing an exhaust leak on this vehicle, the grounding cable that attaches to the engine block appeared to be chafed, partially crushed, and exposing some copper. The grounding cable runs down the firewall of the passenger side of the vehicle, runs briefly along the frame rail, and passes underneath the exhaust manifold. There is a potential for the cable to not properly ground over time, causing unknown issues. The vehicle has not been inspected by the manufacturer or dealer as this vehicle is outside of bumper-to-bumper warranty. A support case was opened with GM, but as an individual, they will not allow me to report the issue with pictures. They require the dealer to be the reporter.

When you push on the break the vehicle-??s power shuts down. Yes it is available for inspection upon request. When steering wheel is turned it dies. After this happens stabilizer light comes on and power steering assist comes on. No inspection has been done called dealership and they said the recall from 2014 had already been done. This is a very serious issue when driving in traffic and I do not want to be in or cause an accident

From time to time the vehicles power system will surge, blink, and generally act up. The priblem is intermittent. The check engine light will come in then go off, the engine has completely cut off several times while driving, the transmission acts up, radio will turn off, 120v outlet will turn off, occasionally the vehicle will fun for 5-15 seconds after being turned off and then sputter off. And 95% of the time the truck is absolutely fine.

I had made a appointment to get the recalls resolved at the dealership and I made appointment and everything and they call to confirm thru out the week and then when I showed up they said they couldn-??t fix it cause it was a branded title and they didn-??t even offer me any other way of fixing it.

While passing a vehicle I lost all electrical power which in turn caused the vehicle to lose power. This same thing has happened several times at low speeds. I have the vehicle scheduled for July 2 to get looked at. The engined revved extremly high and it seemed like the transmission went into neutral. It then restarted. I had to roll the driver's window down and got a stabili Trak light that came on after the incident.

Vehicle started having random electrical problems including dropping out of cruise when signaling a lane change, not starting due to antitheft system error, stabltrak error message, message to raise & lower drivers side window. Ultimately the engine, steering & brakes failed, fortunately at low speed, and we coasted to a stop after the truck ran over a curb. Our safety was at risk as we could have crashed into something. Others safety was at risk as we could have ended up in their vehicle path. The dealer replaced some ground wires, at great expense, and said that usually fixes it. Which tells me that this is a known problem. Can't believe that it isn't a safety recall!

The contact owns a 2014 GMC Sierra 1500. The contact stated while driving the vehicle, the steering wheel would violently shake and vibrate before the vehicle shut-off. Later the vehicle was restarted and operated as normal. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The manufacturer was also notified of the failure. The failure mileage was 30,000.

On several occasions spanning multiple years the truck loses power while braking and turning at slow speeds. On more rare occasions, but still numerous, the same problem occurs when braking at higher speeds without turning. The truck dash lights, media screen and headlights all dim or flicker as a ticking or popping noise is heard behind the dash much like an arching electrical wire. Most of the time when these scenarios happen the display on the drivers display screen reads stabiltrak warning. Also when the problem occurs while turning and braking at low speeds the truck will completely lose power and power steering as well as assisted braking. Once the truck comes to a stop the ignition, and all electrical systems are completely unresponsive like the battery is dead. In order to start the truck again, I have to get out of the truck, open the engine hood and oscillate both the negative and positive battery cables. Most of the time the truck will start up after doing this. Sometimes I have to use booster cables to get it to start. Neither the cables or the terminal connectors are loose as they have been inspected by a dealer service tech and a local mechanic.

After about 5-10 minutes of driving there was a 'burning plastic' smell and about 1-2 minutes after that a loud bang (almost like a gunshot) after pulling over, I looked around to find the left side of the back window was blown out. Long story short, I called the dealer to set up service and was told they performed the recall fix for this problem on my GMC.....I don't think it was either done or the fix didn't solve it. I can provide pictures tomorrow.....and I was driving down a city street and in motion - the street was not bumpy, in fact it was snow covered. I think this could have been a fire hazard judging by the horrific smell.

2014 GMC Sierra 1500 4WD ~75K miles. Sometimes when I roll up my windows or use my blinker and it shuts off cruise control (hwy). And sometimes when I hit my breaks my headlights will dim (hwy, city streets, parking lots). When I'm turning slowly (in parking lots) the steeling will occasionally lock up and once it lost power entirely. My battery was tested at bigo and said it was fine. I've seen this online a lot for this truck and similar years, but no one seems to have a resolution. With so many incidents I'm shocked they don't have a fix or any idea what is wrong.

Intermittently getting "service stabilitrak" "electronic steering assist power reduced" messages while turning left at speeds 30mph or less. Each time I receive this message the steering wheel becomes very hard to turn and jerks. Several times the vehicle has died but restarted itself. On 2 occasions ( thankfully in a parking lot away from traffic) the vehicle died after these messages and would not restart, no systems would respond to turning the key for several cycles. Both times this has happened I also received an anti-theft message as well. I know there is a recall issued for this but GM is not listing my VIN as an affected vehicle. This is a potentially life threatening issue and needs to be corrected

The truck shuts off while driving which disables the power steering, engine and power braking. The electrical systems seems to reboot and turn back on after a second or two. This also happens occasionally while driving at slower speeds and turning the steering wheel or after hitting the turn signal. I have had the entire electrical system and engine shut off while doing 50mph on the high just because I turned my turn signal on. This happens every 4 weeks or so. You can tell it is about to happen when the headlights start deeming when tapping the brakes or using the turn signal. It usually happens when the truck is in motion. It has happened in all temperatures. After it happens the console states "stablitrak is disabled".

I was driving down the road and all of the sudden it was if my transmission disengaged and my car lost power. It then automatically came back on and the 'service stabilitrak' lights came on. I nearly avoided an accident and was able to pull off onto the side of the road.

The vehicle was in motion and took a turn the dashboard chimed and showed a "service stabilitrak", and redcution in power steering, and HVAC went off and came back on and I lost power steering. Everything flashed and flickered. Upon further assessment at my house stationary turning the wheel reactivated the problems and it was also noticed that the lights would flicker and go dim along with the dashboard lights. Looked up some recalls and saw some recalls on 2014 GMC Sierra with loss in power steering, however my vehicle was not included in that. I have a brake recall that I will be servicing and hopefully that might solve this dangerous electrical problem.
