2014 GMC SIERRA 1500

SEAT BELTS:FRONT

General Motors, LLC (GM) is recalling certain 2014-2016 Chevrolet Silverado 1500, 2015-2016 Chevrolet Tahoe, and 2014-2015 GMC Sierra 1500 vehicles that may have received an incorrect replacement tensioner cable assembly as part of a previous recall remedy or a subsequent repair. The flexible steel cable connecting the driver's seat belt to the outboard side of the seat may be repeatedly bent over the seat side shield as the driver enters and exits the vehicle causing the cable to fatigue and separate.

Risk: A broken pretensioner cable reduces the effectiveness of the driver's seat belt, increasing the risk of injury.

ELECTRONIC STABILITY CONTROL (ESC)

General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.

Risk: Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.

SERVICE BRAKES, HYDRAULIC:POWER ASSIST:VACUUM

General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.

Risk: As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.

EQUIPMENT

General Motors LLC (GM) is recalling certain 2009-2014 Chevrolet Silverado HD and GMC Sierra HD, 2009 GMC Topkick 5000, 6000, 7000 and 8000 Series and Isuzu F Series, and 2009-2018 Chevrolet Express, and GMC Savana vehicles, equipped with certain Plastic-Handle Fire Extinguishers or Push Button 'Pindicator' Fire Extinguishers. These extinguishers may become clogged, preventing the extinguisher from discharging as expected or requiring excessive force to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable. For a full list of the affected fire extinguisher models visit: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17E062-5427.pdf

Risk: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.

AIR BAGS:FRONTAL

General Motors LLC (GM) is recalling certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles, 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles, 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles, and 2015-2017 GMC Sierra HD 2500 and 3500 vehicles. While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.

Risk: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.

STEERING:ELECTRIC POWER ASSIST SYSTEM

General Motors LLC (GM) is recalling certain 2014 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles. The vehicles may have a temporary loss of electric power steering (EPS) assist, especially during low-speed turning maneuvers.

Risk: If EPS assist is lost and then returns, the driver might lose temporary control of the steering wheel, increasing the risk of a crash.

AIR BAGS:FRONTAL

General Motors LLC (GM) is recalling certain model year 2015-2017 Chevrolet Silverado 2500 HD, 3500 HD, Tahoe, Suburban, GMC Sierra 2500 HD and 3500 HD, GMC Yukon, GMC Yukon XL, Cadillac Escalade and Cadillac Escalade ESV vehicles and 2014-2017 Chevrolet Corvette, Silverado 1500, Trax, Caprice Police Pursuit Vehicle, GMC Sierra 1500, Buick Encore, and 2014-2016 Buick Lacrosse, Chevrolet Spark EV and SS vehicles. In the affected vehicles, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.

Risk: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.

SEAT BELTS

General Motors LLC (GM) is recalling certain model year 2014-2015 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks manufactured January 29, 2013, to January 21, 2015. While entering the vehicle, the seat belt tensioner cable may be positioned such that the driver slides over it. This movement may result in the fatigue and separation of the cable.

Risk: If the tensioner cable separates, the driver may not be properly restrained in the event of a crash, increasing their risk of injury.

POWER TRAIN

Catastrophic transmission failure. Original transmission failed at 113,00 miles. I replaced it at the dealership with a factory rebuilt transmission and that transmission failed after only 40,000 miles. Now the vehicle is back in the dealership shop and they want me to replace the transmission a third time. This transmission is the 6L80 which is prone to fail, the torque converter fails and the transmission locks up I contacted General Motors and filed a complaint with them and they said they would not take any action or assist me with the repair.

SUSPENSION

Within the first week of buying my 2014 GMC 1500 SIERRA, the transmission fluid was black in griddy. I have had it flushed, then filter changed and new fluid put in within 2 week time frame. A week later had to put a new transmission in it. It barely would drive. So a purchase at 2,999 then to a transmission 4,800 and new control arm with ball joint with new axels. They were busted. Another 2,000. Its sicking. Advice

EXTERIOR LIGHTING:HEADLIGHTS

The contact owns a 2014 GMC Sierra 1500. The contact stated that while her husband was driving at various speeds, the front headlights failed to function as intended. The contact stated that the headlights were dim and foggy. The failure limited the driver's visibility, preventing the driver from safely operating the vehicle. There were no warning lights illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure recurred, and the contact was no longer driving the vehicle at night due to the safety concern. The failure mileage was unknown.

SERVICE BRAKES

The brakes on my GMC Sierra 1500 lose braking power when operating at slow speeds. The brake pedal will lose braking power, causing the vehicle to not stop at slow speeds. This is particularly troubling when pulling into and out of parking spots, driveways, crosswalks, and other areas. I use my truck to pull a boat and when I back my boat into the water at a boat launch, the brakes will lose power when I am in reverse causing the truck to slid into the water.

SERVICE BRAKES

I am experiencing an issue with a hard brake pedal on my 2014 GMC Sierra 1500. This same issue was previously addressed through a recall and special coverage program by GM, which I had performed. However, the hard brake pedal condition has returned, significantly impairing stopping power at low speeds. This poses a serious safety risk, especially when towing or parking. I can no longer park my trailer safely. The vehicle is difficult to stop, and braking distance has increased substantially. This is a known issue with this model and year. It appears the prior recall may not have adequately resolved the root cause. I am requesting that NHTSA investigate whether additional action or recall extensions are warranted.

STEERING

The contact owns a 2014 GMC Sierra 1500. The contact stated while driving at an undisclosed speed and attempting to turn the steering wheel, the vehicle lost power steering functionality. The contact stated that the failure had recurred intermittently and had progressively worsened. A message advising of a power steering failure and to drive safely was displayed. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 150,000.

POWER TRAIN

The contact owns a 2014 GMC Sierra 1500. The contact stated that while driving on several occasions at speeds of approximately 35 MPH, the transmission shifted abnormally, and the vehicle started vibrating. Additionally, the contact stated that while driving at speeds of 65 MPH and higher, the failure worsened. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 146,000.

ENGINE

The contact owns a 2014 GMC Sierra 1500. The contact stated that while driving on the highway at 55 MPH, the vehicle lost automotive power and the steering wheel became stiff. The contact stated that the vehicle decelerated to 20 MPH, with several unknown warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed, and the contact was informed that the engine had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 101,000.

ENGINE

The engine has 160,000 miles and just driving the camshaft and the lifters went out during normal driving. It showed no problems before hand. I’ve heard from multiple people that this is a big issue with the 6.2l gmc Sierra engines. The mechanic also stated it’s there biggest problem. The repair cost are $4,000 - $6000 dollars and the have to pull the whole engine and just fixing those two things. The cost of an engine is $7000 for a used with 100,000 miles and to me it would just happen again in around 60,000 miles or less. For a new engine non oem so an off brand it would cost $8,00 - $10,000 just for the engine. Almost as much as the truck cost not including the labor. This is completely unacceptable cost for repair for a common problem with this truck.

ENGINE AND ENGINE COOLING

The contact owns a 2014 GMC Sierra 1500. The contact stated while driving 60 MPH, the check engine warning light illuminated. There was an abnormal knocking sound coming from the engine. The contact determined that the engine had seized. The contact stated that the failure was related to NHTSA Campaign Number 25V274000 (Engine and Engine Cooling). The vehicle was towed to the local dealer, where it was diagnosed and determined that the failure was due to the lifters, and there was low compression in the engine. The vehicle was not repaired. The vehicle was towed to an independent mechanic. The manufacturer was not contacted. The failure mileage was approximately 100,000.

ENGINE

I am the original owner of a 2014 GMC Sierra 1500 (VIN: [XXX] ) and began experiencing serious mechanical and electrical issues while the vehicle was still under warranty around 40,000 miles. These included engine RPM fluctuations at idle, vibrations under acceleration above 65 MPH, and intermittent misfiring — all symptoms that are now believed to be early indicators of defective lifters or valve train components. I also experienced repeated electrical failures including a rear turn signal malfunction due to melting/corroded taillight sockets, a thumping rear-end noise, differential knocking, and body panel issues (hood lifting at highway speeds). These were reported multiple times to authorized GMC dealers (Mike Haggerty GMC and Rizza GMC), but I was told there was no issue or no repairs were made. GM refused to assist when I escalated the issue in 2017 via a detailed email, despite all problems occurring within the warranty period. I’m now dealing with a persistent ticking sound from the engine and loss of power, which matches widespread reports of lifter failure in GM’s 5.3L/6.2L V8 engines. These failures pose both a mechanical and safety risk due to stalling, misfiring, and potential electrical fires (in my case, from a failed taillight socket). A class action lawsuit ([XXX], et al. v. General Motors LLC) has been filed regarding these known defects, yet GM has not issued a recall. I’m filing this complaint to add my case to the record and urge NHTSA to investigate these issues. I have full documentation of the original complaint and am willing to provide it upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving around a lake with my family. We were fishing. I had no warning at all and my transmission started to sputter and jerk extremely bad and my brakes did not work at the same time. I had to use my parking break to stop my family and I from going into the lake at 40mph. I looked up on many websites and forums and saw multiple people with the same issue. I am afraid that this will happen to a young driver and it be very tragic. Please do a recall. My truck is still sitting at my house broken. I am on disability and can not afford to fix it. I just keep paying my payments with no use of my truck. Please I beg of you.
