SEAT BELTS
My drivers side seat belt cable broke. I did some research and there was a recall no. 16V209000. I took my vehicle to Swickard GMC dealer in Anchorage AK to get repaired and they fixed the seatbelt but told me it wasnt covered under the recall because the recall had already been completed in 2015. The issue with the seat belt breaking is exactly the issues in the recall and believe the recall was not completed or was completed unproperly.

POWER TRAIN
I was driving and was almost home when I heard a pop and started getting jerked back and forth and then just slowed down almost to a complete stop with vehicles approaching quickly almost causing a multiple vehicle pile up I’ve heard multiple people complain about the particular transmission that is put in these gmc and chevy 1500s and am just confused with all of the problems I see on the internet and hear from peers in person why it has not been recalled yet if need be I will make a survey of gmc and chevy owners to let it be known that the transmissions on these vehicles were poorly built and need to be recalled before anybody has this problem that I had today

FUEL/PROPULSION SYSTEM
The vehicle experienced a catastrophic failure of the fuel pump while towing a horse trailer on a busy state highway. This was a major safety risk because the vehicle gave no warning before it just stop working. It was a miracle we were able to coast off the highway into a wide spot that was able to accommodate both the truck and the horse trailer. The truck only has 77,000 miles and we are being told that none of the repair is covered under warranty. We were also told that the fuel pump has completely contaminated the entire fuel systems, including the injectors so everything must be replaced. The quote we received from the dealership for this massive repair is $12,208.59. No warning lamps, messages or other symptoms occurred until the truck died. Once the truck died, it could not be restarted and then began displaying a code that said the fuel filter needed to be replaced.

STEERING, ELECTRICAL SYSTEM
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.

SERVICE BRAKES
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!

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
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.

SERVICE BRAKES, ELECTRICAL SYSTEM
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.

SERVICE BRAKES, STEERING
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
