2014 GMC Sierra 1500
Recalls and owner complaints reported to NHTSA
Compared with the typical (middle) count of 1,110 complaints across the 6 model-year 2014 half-ton trucks we cover. Best-selling trucks naturally collect more complaints because more of them are on the road.
Price & value
We don't guess at prices. Get a real value for the exact truck from Kelley Blue Book, then see how the asking price compares.
Is it a good deal?
- Look up the truck on Kelley Blue Book. Choose its cab, trim, options, miles, condition and your ZIP code, and note the private party value (or the fair purchase price if you're buying from a dealer).
- Enter that value and the asking price below.
Enter both numbers to see the deal rating.
The rating only compares the two numbers you enter: within 5% of the value is a good deal, 5–15% under is a great deal, and more than 15% under is a buy-it-now price. Know Your Truck isn't affiliated with Kelley Blue Book. Rust, accident history, lifts and mods, and service records all change what a truck is worth, so always get a pre-purchase inspection.

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.
Fix: GM will notify owners, and dealers will replace the driver seat belt lap pretensioner, free of charge. The recall began on May 5, 2021. Owners may contact Chevrolet customer service at [phone removed], and GMC customer service at [phone removed]. GM's number for this recall is N212330040.

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.
Fix: GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at [phone removed] or GMC customer service at [phone removed]. GM's number for this recall is N192261050.

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.
Fix: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017. Owners may contact Buick customer service at [phone removed], Cadillac customer service at [phone removed], Chevrolet customer service at [phone removed], or GMC customer service at [phone removed].

Back up lights and Tail light problems My Back up lights turn on when the headlights are turned on and do not shut off unless the headlights are off. Also, recently, the rear tail lights were burning out early and would last only two weeks. The source of the problem seems to be in the fuse box. There is no short in the system. It appears to be in the fuse box of the 2014 GMC Sierra 1500. Bulbs were replaced and burned out quickly. Replacement parts are expensive and this problem exists on other Chevrolet and GMC trucks.

At low speeds, and not 100% of the time, the power steering will go out while I'm turning. It just does it on its own and will correct itself in a few seconds, usually when I'm done with the turn. It's at very low speeds, like parking in a parking lot or turning around in front of my house. So far no issues turning at normal speeds in traffic. Very scary at the low speeds especially since my wife and my young daughter might drive it in a year when she gets her license. I can kind of still turn it, but I know they can't and a new driver will more than likely panic.

The vacuum pump has been recalled on same year, make and model vehicle, yet my particular VIN is falling to the wayside. IT HAS A VACUUM PUMP issue, causing the brakes to malfunction at slower rates of speed. A "computer programming recall" was applied to my VIN however it is the ACTUAL Vacuum pump that is the problem. This should have been covered in all year, make and models. BRAKES ARE IMPORTANT! Reprogramming did not solve the vacuum pump issue that is causing the brakes to fail!

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.

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.

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.
- Filed Nov 2024
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.

I am experiencing ongoing issues with the 6L80E transmission that have significantly affected the performance and reliability of my vehicle. The transmission shifts harshly between gears, hesitates when accelerating, and occasionally slips before engaging. There is also a noticeable shudder during acceleration and inconsistent shifting, especially at lower speeds. These problems have become more frequent over time and raise concerns about the safety and dependability of the vehicle. The transmission does not operate as expected for normal driving conditions, and the issues negatively impact the overall driving experience.

The vehicle experienced complete lifter failure on cylinder number 4 bending the intake valve push rod thus shutting down the cylinder. The vehicle has 167,000 miles and is well maintained. The vehicle gave no warning signs that there was a problem. Simply driving down the road, normal engine temperature, normal oil pressure, the check engine light comes on at the same time the engine begins to mis-fire. Pulling over to the side of the road, I could hear lifter noise from the right bank of the engine. The dealership (Ocean Crest Chevrolet/GMC Warrenton, Oregon) confirmed the damage. The mechanic and the service manager both state the damage is a direct result of the GM cylinder deactivation system, and every single one they have repaired has been cylinder number 4. They further stated that GM has recommended a lifter change when repairing the damage, in other words, the lifters that were installed when the engine was originally built are defective. This damage occurs on both the 5.3 and the 6.2 with cylinder deactivation, and according to the dealership, it begins with cylinder number 4. This problem has also been responsible for cam damage which results in total engine replacement/rebuild due to metal contaminating the oil.

The contact owns a 2014 GMC Sierra 1500. The contact stated that while driving approximately 45 MPH, the vehicle drove over a slight bump in the road. The contact stated that the vehicle bounced, and then there was an abnormal banging sound coming from the rear of the vehicle. The contact recently had work completed on the exhaust system. The contact took the vehicle back to the independent mechanic who had performed the exhaust repair. The mechanic raised the vehicle on the lift and became aware that the rear passenger’s and driver's side cross members, supports for the shock absorbers, and the rear sub frame had extensive corrosion. The contact was advised by the mechanic that the banging sound was coming from the shock absorbers striking the bed of the truck while driving over the bump in the roadway. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was 78,569.

The vehicle’s frame has severely rusted to the point of structural compromise. My certified mechanic determined on December 10, 2024, that the frame could not pass the state safety inspection due to advanced corrosion. Welding is now required to restore structural integrity. The truck has remained inoperable and sidelined since that date. The frame is available for inspection upon request, and I have photos, repair invoices, and a mechanic’s written evaluation. This same frame was previously reworked by GMC twice: May 7, 2018 – Frame treated for premature rust. November 4, 2019 – Frame recoated after prior treatment failed due to improper descaling. Despite these reworks under GMC direction, the issue has progressed to a dangerous level. The structural integrity of the frame is compromised. A severely rusted frame puts occupants and others on the road at risk in the event of a collision, towing, or even regular driving. A weakened frame could lead to loss of vehicle control, failure to protect occupants in a crash, or catastrophic breakage of suspension or driveline components while in motion. Yes. The problem has been confirmed by an independent certified mechanic, who inspected the frame and advised that the rust is beyond surface level and requires welding to repair. They refused to weld during winter due to safety concerns and advised that the truck could not be driven or pass inspection in its current state. The vehicle was previously serviced under GMC’s direction in 2018 and 2019 by a GMC dealer (Weird GMC) to address early frame corrosion. However, the current failure has not yet been inspected by GMC directly since becoming undriveable in late 2024. I have reached out to GMC Customer Assistance and am awaiting a response. There were no dashboard warning lights or alerts for this issue. The only indications were visible signs of rust, which rapidly worsened after the 2019 rework. My mechanic noted signs of significant corrosion during routine servicing

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)

On my 2014 GMC, the front driver side seatbelt was not latching. We had to finagle to latch it. To which this point we were unsure that we were safe. So I brought the GMC to the GMC Rosedale dealership and after further investigation they charge me $522 to repair replace the belt. I told them it’s a safety issue, but they seem not to care, I also contacted GMC corporate and they are investigating this. So if it state law that you have to wear a seatbelt for your safety, why do dealerships charge you to repair or replace them.?

THE MAINTENANCE/SERVICE PERSON AT THE DEALERSHIP INDICATED THAT THERE HAS BEEN NUMEROUS COMPLAINTS FROM OWNERS. HE INDICATED THAT AT THIS TIME IT IS A "NO FIX" PROBLEM. THIS IS UNACCEPTABLE AND DOES NOT MEET THE NATIONAL HIGHWAY TRAFFIC BOARDS REGULATIONS ON HEADREST EQUIPMENT. THIS IS A REAL SAFETY CONCERN.
