2014 GMC SIERRA 1500 Complaints

It turned off while driving on freeway I immediately put on N and start back up. It also pulls back as I’m driving normal 35mph. My Rpm gaug goes up to 3 while driving down hill and locks

Hello, I am driving a 2014 Sierra truck with 17,761 miles, my father’s work truck. The first week I had No problems, the 2nd week the Trailer Brake warning came on relentlessly. New truck, scary Warning sign! I took it to GMC to dislocate trailer brake, they sold me a $340 trailer brake control switch. Upon my return to where I live a loud sound came from when I was idling to wait for construction to accelerating. I noticed once I got home, my back wheels were hot and a burning smell! I hate when you take your car in for one warning sign and you get something so much worst and you paid outrageously for that! Karma!

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 was driving my truck when the Brake assist light came on. When applied the brakes they started pulsing and grabbing. I took it in for service and was told that the Electronic Brake Control Module needed to be replaced and the brake fluid flushed.

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.

The contact owns a 2014 GMC Sierra 1500. The contact stated that while driving 20 MPH, the power steering failed. Additionally, the dashboard lights and headlights became dim, and the HVAC system shut-off inadvertently. The stabilitrak and "Reduction in power steering" warning lights were illuminated. The vehicle functioned normally moments later. The vehicle was not diagnosed nor repaired by a dealer or independent mechanic. The manufacturer was made aware of the failure and informed the contact that there was a recall related to the failure that was already repaired and to take the vehicle to a dealer. The contact related the failure to NHTSA Campaign Number: 17V414000 (Steering). The failure mileage was approximately 65,000.

We have been told that the recall #17V414 has been completed on our vehicle. However, we have only owned this pickup a little over a year and now the power steering has gone out again. it is throwing a code U0131 which says it is lost communication with power steering control module. We have been told that the power steering module needs to be replaced. I would like to delve into how many people have had to replace this (which is a very EXPENSIVE repair). I truly feel this is still a defect and GMC should own this problem. Thank you for your time.

Driving at certain speeds the truck will just shut off while trying to turn or merge onto the highway. The electronic steering draws to much voltage on the vehicle and it just dies turning and braking after that is a very serious safety hazard and should be looked into I’m a mechanic myself and I’ve replaced grounds done everything I can and still nothing has fixed the issue
