2014 GMC Sierra 1500 complaints

Severe gas smell. Brakes hardly stop truck. Service stabilitrac. Paint peel. Steering clunking. Antifreeze leaking

NHTSA Campaign Number: 14V246000 Q1- my steering column is faulty and it is on the verge of collapse. Q2- every time I hit a pot hole my truck loses control for a second and it has gotten progressively worse. The car sways from left to right without me moving the steering wheel. Q3- I’ve been having suspension problems that have become worse and worse after being told I’m having suspension problems. I fix what I am suggested too and the problems have worsened. Q4 yes it has been inspected and the issue has been overlooked. Q5 if I try to drive the truck again it will fail, I changed my rotors at the beginning of last month and the two front side rotors have been warped and replaced as of Saturday. I drove my truck just fine until tonight I began losing control of it two times. My brakes are beginning to fail. My brand new rotors have been ruined in less than two days. That’s 4 new rotors in a month. When I arrived at home I opened the hood and applied a very small amount of pressure on the steering columns shaft and it had a lot of play. I added a little more pressure and it moves a lot it felt like I could’ve taken it apart with my hands if I really tried. I’m pretty sure I shouldn’t be able to move the steering column shaft with only my hands if the truck is off.

Recall on brakes says it's fixed. My brakes fail alot suspension chunks all the time and steering feels like tire is falling off

The truck started making a grinding noise when turning steering wheel left and right. I took the truck to local GM dealer/mechanic for inspection. It was diagnosed as a failing steering rack and recommended replacing the steering rack. A failed steering rack can cause partial or complete loss of steering and potential vehicle accident. As of this time, GMC cannot provide a replacement steering rack and there is no estimated availability timeline.

Today I was driving on a residential road and my truck completely stopped while driving. My wheel locked up and I was unable to steer and almost hit another car. This has also happened a few weeks ago while driving on the highway at 70 miles per hour. My vehicle shuts off, I turn the key back and then restart it and I get the following 2 messages: 2 Keys programmed, and Open then close driver window. This is very dangerous and apparently a major problem with other vehicles as I have found the below additional details. This puts my family and others at major risk. I have asked to dealership to look at it but they state they have to keep it for several days and see the issue for themselves, and since it happens so sporadically I cannot be without my vehicle for that amount of time. Apparently it is an issue with the ground wires ands wiring harness. chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://static.nhtsa.gov/odi/tsbs/2017/MC-10113356-9999.pdf https://www.youtube.com/watch?v=gvpsaDm-jj4

What component or system failed or malfunctioned, and is it available for inspection upon request? How was your safety or the safety of others put at risk?: The truck just stalls and dies without warning, all lights go off inside and outside and all power is lost. From digging on the internet, I found out the problem is due to one or more rusty/defective connection to ground which stops current from flowing and therefore stalls the vehicle and turns everything off. When the truck stalls, power steering and power assisted breaks are not available and this makes the truck very difficult to guide/stop for most people, making it a significant safety risk to occupants as well as others as the likelyhood of a collision increases significantly. In addition, since all electric accessories are disconnected, warning/flashing lights can not be turned on to advise others that the truck has stopped. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem is hard to reproduce because it happens at random times, it has happened to me at least 5 times in the last month or so. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? NO Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NO warning messages or other symptom.

I am losing engine power. My OBD2 gives me P2138 and P0700 codes. I have changed the accelerator and knock sensors.

In several areas on the exterior of the truck, the paint has bubbled and is peeling off. This is despite my efforts to really take care of my paint.

Noticed that there was a recall on this vehicle NHTSA Campaign Number: 19V645000. My concern is that I took my vehicle in back in 2018/2019 for this repair. However my vehicle vacuum pump completely failed the other day where I cannot brake. My vehicle is only at 70,800 and fail to see that if a proper repair was completed back in 2018/2019 for it to fail again a couple of years later with low mileage. While I was able to get this vehicle home safely my concern is that if it failed earlier in the day on the highway I may have cause a serious incident.

Going under 15mph, applying the brake causes the pedal to become stiff and lock up and not work. This has caused me to almost hit someone in traffic. I immediately got off the road and got my vehicle to a safe location off the road . Communicating with a dealer today to confirm possible recall issue or potential repairs.

Fuel management system requires an add on to keep system from functioning improperly. Lifters making loud tapping sound

This truck has a 5 star crash rating, but is rusting very badly due to a defect in the design of the truck. There are tracks in the roof that lead down behind the cab. The water rolls down and then there is an indentation that holds the water. This water holding creates rust, horrible rust. The rockers, frame and the fuel pump rusted badly due to this defect. The 5 star crash rating comes into huge doubt due to such rust from the design defect.

My truck goes into “neutral” or doesn’t have power while driving at times and can cause a car crash.

At low speeds excessive brake pressure is required to stop my truck. Other GM trucks have been recalled for this issue, but i am told my vehicle is not included.

Service brake lights come on. Brake pedal locked up and lights dimming and transmission shifting irrelevant

NHTSA Campaign ID 21V245000 Truck is issuing a service air bag alarm, was my truck given wrong part on original recall. Purchased 2 months ago

At low speeds my power steering will cut out. Today I almost hit a guy at a gas station when my steering went dead and got stiff for a second then came back. After some research I see over a million trucks were recalled for this.

I had the a/c condensor and low pressure line replaced due to the cracked welds on condensor

In the process of making a right turn my power steering suddenly quit working causing my vehicle to cross over into oncoming traffic. There was an eighteen wheeler that had to make a lane change to avoid a collision. At this time I had a warning light come on stating a problem with the power steering. I was able to slowly drive the vehicle to a local repair shop. The shop had to reprogram the steering module. I know my model had a safety recall for that very issue and I had it repaired at a GMC dealer in 2017. Apparently the problem still exists and I called GMC Corporate and was told that my vehicle had been repaired and was to old for any assistance. I now have no confidence in my vehicle knowing that this problem could occur at any time.

"Service Trailer Brake System" alert on dash. This is a safety concern for 2 reasons; the first being the chime made to warn the driver is distracting, persistent, and annoying. The second is the trailer brake system is apparently not functioning properly which is a danger while towing. This is not the first time this has happened and is a danger to me, my family, and other on the road.

My truck recently had an engine lifter fail when pulling out onto a very busy road. When I accelerated hard into traffic my check engine came on and I suddenly lost most of the engine power and it went into limp mode. I was almost rear ended when my truck nearly came to a stop. I was told it is a defective/poor design of the cylinder deactivation system from the dealer. Ther is no fix but to replace with the same lifter part number which was done and it also failed again 4 days later in a similar situation turning onto a road into traffic. My truck is now back in the shop to have lifters replaced twice in one weeks time.

Service trailer brake system warning message. Trailer brake controller inoperable.

Whenever driving I get a message stating that I need to service my trailer brake system. This is most likely due to cheap wiring installed by the manufacture. This has been going on for over a couple of months. Just recently, I was making a slow turn and my vehicle shut off on me and I lost control of my brakes and steering and all power to the vehicle which is a huge safety concern and I am unsure if they are related or not

While driving, the vehicle will briefly shut down and lose all engine and electrical power. The GMC dealer was alerted and I was advised to the battery cable that were burned out and the starter shield.

Air bags didn't deploy on 2 separate incidences and brakes went out last incident

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.

Lose power steering at low speeds typically in a low speed turn. Stabilitrack warning appears on the dash and sometimes lose power to the entire dash including radio and A/C.

AFM lifters are failing at a high rate. Had lifters replaced for $3k a year an half ago at 125k miles and they failed again at 149k miles just recently The problem is getting worse with the newer models

Cross frame member ahead of rear wheels has rotted and failed. It is located behind the cab and is the cross frame that holds up gas tank and forms the anchor point for the rear shock absorbers. I have been told by dealer that truck is not safe to drive. It is now at a body shop. The suspension is compromised, gas tank could fall, and drivability safety is affected. Truck is only 8 years old, the cross member is not visible to consumer, there has been no undue use or environmental conditions to cause the rot and failure of the component. Further, the manufacturer does not sell a replacement part, so the entire frame of the truck would need to be replaced.

My vehicle recently started "shuttering" while driving. Service report says it is a "common GMC issue with the Torque Converter", $3200. They also reported a "substantial leak" in the radiator, and again, says it is a very common fault of GMC Trucks. And another $2700. If these conditions are as common as they indicate, why are there no corrective measures?

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.
