When I slow down to make a turn, my truck loses power making the turn very dangerous. I lose control of the vehicle for a few seconds due to loss of power. It is very dangerous for me to make turns.

The contact owns a 2014 GMC Sierra 1500. The contact stated that while driving approximately 10 - 15 MPH with the rear defroster activated on the rear powered sliding window, there was a sizzling sound, and started smelling smoke inside the vehicle. The contact pulled over, stopped, exited the vehicle, started inspecting inside the rear of the vehicle; and saw smoke on the driver-??s side rear of the vehicle, between the window and the seatback. While the contact was bent over trying to ascertain where the smoke was coming from, the driver-??s side rear window exploded. The contact poured water on the window to put out the smoke. During the explosion the contact sustained a mild concussion and severe earache that lasted for two days; however, medical attention was not needed. The Fire Department and Police Department were contacted and notified of the failure. The contact was informed by the Fire Department that the cause was an electrical system fire. The vehicle was driven to the local dealer to be diagnosed however, the cause for the failure was not yet determined. The vehicle was not yet repaired. The manufacturer was contacted regarding the failure but no assistance was offered. The VIN was not available. The approximate failure mileage was 150,000.

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.

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.

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.
