general problems of the 2014 GMC Sierra 1500 - part 1

1. While driving slow or making a right hand turn the vehicle turns itself off 2. Periodically the car does not start/no power and does not respond to keyless car lock 3. Periodically the dashboard panel lights will not turn off, flash or some will go off but not all all of the above have been a twice repaired GMC recall 17276 and has been occurring since 2020.

Rusted out frame. 130k miles and well cared for. I don't think a 10 year old vehicle should have a rust hole in the frame.

While driving, my wife and I heard a bang, and when she went to turn her head, she noticed that the vehicle was smoking from rear defroster, and the back windshield had smashed. We immediately pulled over and the vehicle did not stop smoking until we turned off the rear defroster. This put our safety at risk as the entire vehicle could’ve caught fire. When we went to check to see if it had been recalled, our vehicle did not have any open recalls but we found that there were many other GMC sierra trucks with this issue. We contacted our local dealer who confirmed that he had seen this happen to other GMC sierra trucks. There was no warning light or other indicator that this was going to happen. Unfortunately, our vehicle was not included under recall n192265660 and we strongly recommend that another investigation is performed to include all 2014 GMC sierra trucks. I have a video showing our vehicle smoking with a smashed, sliding back windshield.

I bought this truck used, in 2022 for $24,000. . . Had it put up on a lift and fully gone over before purchasing. Roughly 18 months later I was notified by the garage that there were some rust holes in the frame that needed to be fixed. I had those holes repaired in March 2024, and the vehicle was inspected. At this time I went over the entire frame and found no more trouble spots. I recently went to trade-in the vehicle to buy something smaller and the dealership told me the frame was "rotted" and that the truck was essentially worthless and actually dangerous to drive. These frames are rotting from the inside out, and go from a sellable and valuable truck, to worthless within months or years. Gm used inferior steel, inferior rust prevention, and is leaving countless owners stranded with vehicles they cannot sell, are unsafe to drive, and are still paying on. I still owe $10,000 on the truck and the best offer I've gotten has been $3,000. My options are to either put thousands of dollars into the vehicle and pray the rest of the frame does not suffer the same fate (unlikely), or junk the truck and buy another vehicle, meaning I'd need to pay two car loans off and only have one usable vehicle. Gm knew about this issue and did not fix it and now hard working americans are being financially devastated because of it. I bought a nice, clean 8 year old truck, and 2. 5 years/20k miles later I'm left with junk and a depreciation of roughly $1 per mile for the time I've owned this vehicle. This has been an extremely stressful situation which has left me coming to terms with the fact that I'm most likely losing $10,000 because of this frame issue. This truck brand new sold for over $42,000 and 10 years later is worth about $2,000, if that. It was not beat, or neglected - simply driven and used as intended. This is unacceptable.

When making right turn steering got hard vehicle seem to loose power and stabilitrak light came on.

The frame of the vehicle is rusted through in 2 areas. I recently noticed the rusting frame. Shortly after I purchase the vehicle the rust preventative coating, that was factory applied, was noticed pealing from the frame rails. I sprayed undercoating on the frame at that time to avoid rust after seeing that the factory application had failed. This has not been adequate as the frame has rusted in an area that the inside channel of the frame did not drain effectively and therefore collected water and salt during the winter months. The frame cross members are also rusting badly. The metal is flaking off excessively. In contrast the trailer hitch on the truck is in very good condition because it is the only part of the frame that appears to be properly conditioned to resist corrosion.

Stability track.

Remote started my truck. Went to get in my truck about 10 minutes later. There was smoke in the vehicle. The rear defrost shorted and melted a hole in the rubber seal next to my rear sliding window. The heat from the incident cracked and spider webbed my rear window.

Engine lifters keep going bad. The frame is rotting like I have never seen. Body is rusting out for second time. Blows lights every month. Rain getting in headliner and under rear seat. Ac breaks every year. All around worst fucking vehicle I have ever owned. GMC will not do anything about this. I'm tried.

My truck shuts off in the middle of driving. Completely losing power to anything electric. I can not unlock or lock the door, the windows, hazard lights, steer the wheel to help me move. I can’t do anything. I have almost crashed.

I have only owned the vehicle for about 5 months now and well it just started seeming like the transmission is starting to slip while also making a noise and just struggling to find what gear to stay in. I have service the car per the gm manual and I don’t drive the car anywhere but to work and back and that’s it. So disappointing that in going to have to replaced the transmission so soon.

I am losing engine power. My obd2 gives me p2138 and p0700 codes. I have changed the accelerator and knock sensors.

Service trailer break.

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 took the vehicle to a local GMC dealer to get the recall corrected but I was told they couldnt fix it because my software was different than the one they usually use and the problem was never fixed.

Ac condenser has a leak I believe is to a bad welding on one off DE lines this happen on June 29 on my 2014 GMC Sierra 1500 whit only 55000 miles on it I been reading a lot complains only I wonder if this is going to come to a safety recall.

On Sunday, may 30, 2021 this truck caught on fire. My son was driving this truck, he looked in the rear view mirror and saw flames coming up between the bed of the truck and the cab. He was on a single lane road following a river, highway 55 in idaho, and the cab immediately started filling with smoke. There is a lot of traffic on this highway and he was trying to find a spot to pull off. His airbag on the drivers side deployed but he was able to push it down and see a dirt area to pull off. There were no warning lights or issues with the vehicle that he was aware of. The police and fire were called to the scene, by bystanders. Obviously my son and passenger were very shaken up by this. My son reported this to geico, his insurance that same day and has been working with the claims adjuster on this. We wanted to report this because this could have so easily been a different outcome. The truck and all belongings in it burned very quickly. It was towed to mustang towing in horseshoe bend, id. No injuries fortunately.

Ac quit working at 62,000 miles. Took it to the shop to see what was wrong. Was told the condenser needs to be replaced that will cost $800-$1,000. Said that this vehicle is known to have issues by GMC and that they have not issued a recall. I am very disappointed that I am going to have to come out of pocket for this expense if gm is aware that there is an issue with the condenser needing replaced in this vehicle.

Vehicle gets stuck in 4 wheel drive. Effects drivability and steering. Safety concern with vibration on dry pavement.

Ac is no longer blowing cold air. Condenser is leaking.

Rear right tail gate bushing - gm (84331136), broke and tailgate slammed down when opening. GMC has has a service bulletin preliminary information dated 09/2016 bulletin # pit5251b regarding this failure. I contacted dealer and their response is that it's not under warranty.

Took the truck to get a diagnostic check due to the truck in driveway would not go into reverse so husband put it in drive to pull up a little to see if it would help to then go into reverse, instead, the truck jerked so hard & almost threw my husband & son into the garage door that morning. Husband & son came back in all shook up. The scan diagnostic code-chck showed: trans fluid-indeed full; but way burnt; needs transmission; front pump making noise in transmission; torque converter; exhaust shows signs of back pressure-and one running hotter than the other; the left side running 100+ hotter than the right - needs transmission assembly removed & repaired; reman gm trans; y-pipe w/both converters; fluids flush nuts bolt gaskets. I was told it would not be a good idea to drive it. I am retired military and maintained the truck throughout my military career, but no warnings showed on the dash reader for something wrong with transmission. It is a 2014 GMC Sierra 1500 slt 5. 3l v8. VIN#[xxx]. Need help if this issue has ever been placed on the recall list? if not, it should be. This issue could kill someone if it were to jerk while driving on the road. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Water leaked through the 3rd brake light and stains the headliner.

Ac problem - my ac just went out for the third time since I bought this truck new in 2013. I went to have it repaired and was quoted ~$1,000 for a new ac condenser. After researching online, it looks like this is a very common and expensive problem that gm hasn't resolved.

Ac failed at 90k miles due to a leak in the condenser. Seems to be a common issue amongst these vehicles. The fail happened on the top right corner of one of the welds connecting an ac line. This the top right corner standing in the front of the truck.

A/c condenser has gone out. Only 72,000 miles on vehicle. Vehicle is only driven on the weekends. This was noticed after starting the vehicle and waiting for the a/c to cool off which never happened. Took to a local auto shop to access the problem.

Started having trouble with brakes, pedal is getting hard at low speeds. Dont have trouble until in at red lights or stop signs. No check engine seems to come up yet.

Air condenser failure. There is a recall for suburbans, yukons and tahoes for the same issue, and same parts, however not for the silverado and sierras of the same year. This is not covered under any recall or warranty from gm/chevy. There are multiple class action lawsuits across the us regarding this topic alone. I do not believe that there should be this type of failure on a 4. 5 year old truck, especially when the original cost of the truck is $50,000.

I have a leak in the a/c condenser. This is a very well known issue. There are stories written about this issue because it is so wide spread. At one point the parts were on back order, that is how many people have had issues. Just contacted gm and they will do nothing about it. They do not consider this to be a safety issue. Yet on the front page of even your website, there is an article about death's from heat rising. So a defective a/c system seems like a safety issue to me- here are the many stories written on the issue: https://www. Nbcchicago. Com/news/local/gm-air-conditioning-responds-439572983.

I have noticed an issue for a few years while parking that my brakes would lock up if used repeatedly. While getting service done I had asked if they noticed anything and they had said no. They have know recognized it is a problem but are limiting the fix to 72000 miles which I am 3k over. They said I have never formally complained about this so I disqualify for the $ 540. 00 repair. Yet they recognize it is an issue with the vehicle. I feel they are trying to avoid a formal recall.

Leaking condensor.

The door locks dont always lock. My grandson was in the back seat and fell asleep, while asleep he bumped the door handle and the door opened while we were going 50 mph. , lucky he had the seat belt on. The door should not have opened as the lock should have engaged when the truck is put in gear and made the door handle inoperable. The door lock actuator is the problem, this will be the second one replaced. You dont know they dont work because they make a locking sound when activated. They just dont lock, very dangerous glad he didnt fall out of the vehicle.

Brakes loose pressure, when pressed on uphill/down hill,in reverse. Ac hose from condenser to compressor is faulty leak out all fluid.

Vehicle will not switch out of auto for the 4x4. Can not switch to 2wd.

A/c compressor failure, $1267. 43 to replace by chevy dealership. Only, 33,000 miles. A known chronic problem as found on internet, gm states out of warranty.
