2015 GMC Sierra 1500
Recalls and owner complaints reported to NHTSA
Compared with the typical (middle) count of 1,003 complaints across the 6 model-year 2015 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 2015-2016 GMC Sierra 1500, 2500, 3500, and Chevrolet Silverado 1500, 2500, and 3500 trucks. The roof-rail air bag (RRAB) inflator end cap may detach from the inflator, or the inflator sidewall may rupture.
Risk: A separated inflator end cap or inflator rupture can allow compressed gas to escape, resulting in the end cap or other components being propelled into the vehicle, increasing the risk of injury or crash.
Fix: Dealers will replace the left and right side RRAB modules, free of charge. Interim owner notification letters informing owners of the safety risk were mailed on August 18, 2021. Owners will receive a second notice when the remedy is available. Phase I owner notification letters were mailed on May 5, 2022. Phase II owner notification letters are expected to be mailed on May 31, 2022. Owners may contact GMC customer service at [phone removed] or Chevrolet customer service at [phone removed].

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].

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.
Fix: GM will notify owners, and dealers will modify the vehicles to prevent the tensioner from being damaged. Any tensioner that has already been damaged will be replaced, free of charge.

I had and still have the Brake Assist failure warning light on and having issues with brake pedal effort not working as it should to stop vehicle and also the stability control warning lights., the brakes hardly work at all at low speeds and most of the time don't stop the vehicle almost causing several crashes. I took vehicle to gm service center and they said they updated software but when I picked up the vehicle and drove it not long after the brake assist warning came back on and I still had no brakes at slower speeds and the problem had actually gotten worse than it was before i took it to them. I called the dealership and told them that the problem had not been fixed and it was worse they said that I would have to pay the service fee / price for parts if I wanted to bring the vehicle back in and to have problem fixed...I explained it was a re call and it was taken to them to have issue fixed in the first place ...and I was told I would have to pay since they updated software ..I then explained it was worse than when I took it to them and still got denied any kind of resolution to the problem. Nothing was fixed or solved. I still had the warning lights on dash and the problem was worse then when I took the vehicle to them for repair. Not long after the transmission went out and the vehicle hadn't been drove. So it sat for 2 yrs or so. I just got a new one put in and the vehicle still has the same problems with the brake system . I reached out to dealership once again and was told I would still have to pay to have the issues fixed when it was never taken care of by them to begin with.

Headlights on this vehicle, since purchased, have not cast enough light in order to see in unlit backroads, or extrememly dim areas. I have to drive with my brights on constantly, in order to get enough light thrown onto the road, for the left and right sides, as well as the front. These were not working well since purchase. I took my child to a friends house in rural PA, and I literally could NOT SEE THE street signs, let alone far enough down the road. I nearly hit a stone wall.. My eyes keep asking to see more, but truck does not produce enough headlight. I even went to the eye doctor, after that situation, thinking it was my vision dimming, but was told I have 20/20. There needs to be a formal recall. I am not the only one complaining about these HORRIBLE projection headlights. To replace these headlights would cost over 1000K, out of pocket, which is not something I should have to fix. I am complaining now, because with the light getting darker earlier, am noticing how lousy driving at night really is.. and honestly, being BLINDED by oncoming LED's , without having proper headlights on my truck in order to see when blinded, really [XXX]. Please address these [XXX]. Make headlights great again! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Lack of illumination of headlights straight ahead. No light shines to the sides of the vehicle making it difficult to see left or right when negotiating a turn at night. I have put new bulbs in both sides the best money can buy at CarQuest with no improvement. The headlight lenses are not dirty or fogged over. It appears to be a design problem, and I have seen other people with this model truck complain about the same thing on some blogs. I contacted GM directly looking for information I can get on a possible upgrade, and they have offered not solution. I have had this issue with this vehicle since buying it used 4.28.2018

The stock headlights both low and high beams provide poor lighting at night. The headlights provide a poor beam pattern making it incredibly difficult to see more than 100 ft in front of you while driving down dark roads. And even more difficult in light storm conditions both rain and snow. The high beams aim too high when used and don't show enough of the road in front of you but rather the tops of tree's or other objects instead of the road. The low beams don't provide much light on the sides of the road as well and at times feel more like they're just fog lights with the amount of light that is put out. These incidents happen anywhere from low speeds up to highway speeds. I have noticed this issue since purchasing it used and have seen multiple similar complaints online.

The transmission Started Shuddering, it would slip occasionally and slipped badly when i was driving in rush hour traffic in the middle of a left turn. had no power for several seconds then it finally reengaged. The shuddering got worse and worse to the point i took it to a transmission shop to look at it and they said i needed a replacement transmission unit. I did get a replacement unit, the whole process was extremely unpleasant. The previous unit was sent as a core to be remanufactured. The company that i used to get a remanufactured unit is Fraser Transmissions. No warning lamps appeared prior to the transmission acting up.

The engine seized up traveling about 40MPH in the middle lane on a busy road with my child in the passenger seat. I was able to get off the busy road but part of my truck was still intruding into the lane. The truck is parked at my house. The vehicle has not been inspected by anyone and is still in the same condition as the day the engine seized. The only thing that indicted any issue was a couple popping noises right before the engine seized. It all happened while I was driving in traffic and I did not notice any indications on dash. I was more concerned about getting off the road and out of traffic before I got rear-ended or involved in a pile up.

I called the dealership and told them that the problem had not been fixed and it was worse they said that I would have to pay the service fee / price for parts if I wanted to bring the vehicle back in and to have problem fixed...I explained it was a re call and it was taken to them to have issue fixed in the first place ...and I was told I would have to pay since they updated software ..I then explained it was worse than when I took it to them and still got denied any kind of resolution to the problem. Nothing was fixed or solved. I still had the warning lights on dash and the problem was worse then when I took the vehicle to them for repair. Not long after the transmission went out and the vehicle hadn't been drove. So it sat for 2 yrs or so. I just got a new one put in and the vehicle still has the same problems with the brake system . I reached out to dealership once again and was told I would still have to pay to have the issues fixed when it was never taken care of by them to begin with.

My son's 2015 GMC Sierra side impact air bags went off while he was driving. He had no impact. He thought he hit a small pot hole but after driving back on the road, it was recently paved so it was not a pot hole. He guessed it was the edge of the road from the recent paving that he hit. He heard a loud noise like a gun shot. His cabin filled up with smoke and the side impact air bags when off. When he took the truck to the GM Dealership, it gave a code for front air bag deployment due to impact. But the side air bags went off and there was no impact. The only damage to the truck is the deployed side airbags and the locked seatbelts. He has a warranty but they kicked it to GM. Warranty stated that if they fixed it, they were worried that it would happen again. We filed a claim with GM. After GM sent three different inspectors out and over 5 weeks later, they denied the claim. They have also not sent the inspection reports as requested. My son did not have this truck for the first three months he owned it because GM could not find the faulty code causing transmission issues. I am worried the air bags deployment will happen again while he is driving at a high speed and cause a serious wreck.

On 9/22/2020 a recall service was performed on my defroster/ power sliding rear window under N192265660. On 1/13/2022 I was driving down the road with the rear defroster on, a smell of burning plastic and a low hissing noise. I was in the process of pulling over to inspect this and the back window of my pickup burst, sending me swerving onto the side of the road. I booked an appointment with the dealer, they are telling me they cannot replace this since the recall was already serviced. Obviously the fix GM is putting into our vehicles is as dangerous as the original design. This needs to be remedied and GM needs to be held accountable, bursting rear windows can cause terrible accidents, luckily I am safe.

The component or system failed was the transmission 4 different times. A new transmission was put in the car just 6 months after purchasing from a dealer. The transmission lasted close to 3 years being shy only a few days before the transmission warranty expired. So a new transmission was provided by the transmission owner at no additional cost for the transmission but we had to pay $1600 out of pocket for labor. That transmission lasted for 2 months before failing again which caused us to have the truck towed to our home to decide what our next step would be. So we had it towed to Tire max and they put in another transmission by the same manufacturer which we only had 2 days left under the warranty. That transmission failed within 2-3 days so we took it back to a different Tire Max location and they put in another transmission which did not cost anything for us by the manufacturer including labor. This transmission has now been in good standing since 12/20/23.

the steering assist fails, Power and steering is reduced at driving speeds. Steering wheel locks and vehicle looses voltage and stalls while driving at low speeds and have been close to collision. Vehicle was inspected by Group One Gmc in el Paso Texas. They did not fix recall because it "did not pertain to my vin" . There is a recall for the steering assist on all gmc 2015 1500, but not for my gmc 2015 1500 for some reason. Whether it was manufactured in the us or the moon its still a gmc 2015 1500 with faulty steering assist system from the manufacturer with an open recall. Thanks for your help

Rainy road, 60mph on the hw with my family. Truck decides to engage stabilitrak or something to that feel and locked up the brakes. Talk about a scary moment with an 18 wheeler coming in hot behind you. Obviously, in the moment, I had no clue what was happening other than something with the truck was malfunctioning. This scenario could have gone wrong in so many ways. I'm honestly in shock someone has not been killed because of this?

When I turn the steering wheel, the ac turns off, lights turn off, the computer screen turns off, steering wheel gets hard and does a jerking movement. The truck turns off too and then suddenly turns on. This can cause a death. If this happens in a highway or a street where speed is high this can easily cause a death.. fortunately this has happened going at 30 mph and no one close at the time and also at a drive through fast food restaurant. It has not been confirmed by the dealer but I will soon have to take it. The only light that comes up is the StabiliTrak.. but it only lights up when it happens and then it goes away.

I am reporting a critical issue with the transmission. The transmission frequently slips, hesitates, and jerks unexpectedly during acceleration and gear shifts. On multiple occasions, the vehicle has lost power or failed to respond while entering intersections, merging onto highways, or attempting to accelerate—posing a serious safety risk. The issue often occurs without warning and has worsened over time. Additionally, there are instances of harsh downshifting, delayed engagement from park to drive, and sudden lurching forward or backward, which could easily result in a collision. Despite visits to the dealership and complaints made, the issue has not been resolved, and I’ve learned that many other owners of this same model have reported nearly identical symptoms. This appears to be a systemic problem with the transmission system. Given the safety risk, especially in traffic and at high speeds, I strongly believe this defect warrants immediate investigation and a formal recall.
