Air bags, side/window, curtain, inflatorJul 1, 2021
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.
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.
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 1-888-988-7267 or Chevrolet customer service at 1-800-222-1020.

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.
A broken pretensioner cable reduces the effectiveness of the driver's seat belt, increasing the risk of injury.
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 1-800-222-1020, and GMC customer service at 1-800-462-8782. GM's number for this recall is N212330040.

Service brakes, hydraulic, antilock/traction control/electronic limited slip, wheel speed sensor/tone ringOct 24, 2019
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.
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.
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 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.

Power steering seems to be lost for a second or two at low speeds turning. Happens multiple times a day.
Steering, Electrical system, Aug 31, 2026
My 2015 GMC Sierra 1500 recently started having all the symptoms under GM internal recall number 18289. I lose my power steering briefly and the electronics turn off momentarily. I lose dash, AC, radio and GPS. It comes back on within a second or two and only does this during low speed turning. I ran my VIN but it does not show under this recall despite having the correct Make/Model/Year. It is currently at the shop because it isn't safe to drive and I was hoping I could get a reimbursement for the repairs. NHTSA Campaign Number: 18V586000 (GM's Internal Number: 18289)

From time to time since I got the vehicle, the lights flicker inside and out. I've had the alternator changed but it continues. Then when pressing the lock button on the key fob the horn sounds as if it has a shortage. Sometimes its loud and sometimes it's barely heard.

The contact stated that while driving at an undisclosed speed and also while the vehicle was parked, the ABS and stability control warning lights would unexpectedly illuminate. The vehicle was taken to an independent mechanic, where the warning lights were cleared. The contact was informed that if the failure recurred, the EBCM and BPMV would need to be replaced. The vehicle was not repaired. The contact stated that the failure recurred. The vehicle was then taken to the dealer, where it was diagnosed that the EBCM and BPMV had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 90,100.
Electrical system, Feb 25, 2026, fire
I remote started my truck, and when I got to it there was smoke and a flame coming from the rear power window. The remote start activates the rear defrosters, which started the electrical issues. I shut off the engine, and a loud pop followed, which was the shattering of the driver side rear window. The flame went out, and could have easily ignited the tarp covering the truck bed. There were no warnings on the console for the issue, and no recalls available. I have seen similar recall, but in a different state and back in 2022. This leaves me with a shattered window in the back, which is unsafe for visibility, and a bill to pay due to manufacturing errors for a feature in the truck. The rear window is all melted, and the glass is chipping away.

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

At low speeds when applying the brake, whether in a turn or traffic, the vehicle will shut off completely. This has happened multiple times and has almost caused accidents on a few occasions. It has also happened while just driving down the road, the entire truck lost power and then came back, the windshield wipers came on as well.

When parking and turning the wheel the truck stalled, radio turned off and on, ac stopped working, battery reading dropped. Maybe an electrical issue since it happens continuously, while making turns at slow speeds the truck wants to turn off, lights dim then go back to normal.

Infotainment screen not responsive to touch, will not reset and freezes with black screen message warning drivers to not take their eyes off the road. Because of the latent defects known to GM in the screen, it is impossible to reset the controls (the "OK" button will not clear the error message). The freezing and non-responsiveness and elimination of outside temperature display creates a driver distraction hazard trying to clear it while driving, and prevents the driver from being alerted to outside temperatures dropping below freezing. GM customer care refused to provide any assistance for the $1,045 repair charge quoted by the dealer and refused to acknowledge that this is an inherent vehicle defect well established, that already produced a service advisory and redesign of the defective screen. Problem has existed for quite some time, and infotainment issues were initially reported to dealer on 3/9/2015 (2 months after delivery) without adequate resolution.

I was driving my truck with my family in the car. I turned on the rear window defrost and a few minutes later the rear window blew out and made a loud bang noise. Also a burning smell took over the rear of vehicle. I did some research on line and saw this has happened to several owners of this model year pick up. It’s 100% a safety hazard. Not sure what to do since I don’t see a recall for this common problem. Thank you.

I purchased my truck (15 GMC Sierra z71 4x4) with around 122,000 miles on it. I would be owner #2. Truck ran great. Around 150,000 miles I noticed my truck's transmission start to jerk while accelerating from gear to gear. No engine light ever appeared. Problem stopped. A few days later while dropping my daughter off at school, my truck wouldn't go passed 35 mph. I had to put the shifter in manual and shift to third gear. Other gears would just rev the rpm's to 4 or 5. Since I didn't want to put my family, me and others on the road at risk. I parked my truck and started driving my other vehicle. A few months went by, and my other vehicle had a flat tire, I had to drive my truck to work. On the way home from work, my truck started acting up again, jerking while accelerating. speedometer would go up however truck didn't move. I had to pull over quickly so I wouldn't be broken down in the traffic lane. I turned the ignition off and waited five minutes and started the truck up. I was able to make it home. At this time the engine soon light came on. I ran my scanner on my truck and code P0700 TCM was the only code showing. I had a Gmc dealer look at my truck and stated I would need a new transmission. I have done many months if not almost close to a year of research with results showing that transmission problems just what I was experiencing are a common problem with 2014-2019 chevy and Gmc / Silverado pickups with transmission 6L80. I dropped my truck off at another transmission shop just yesterday 3/3/24 and the results today were I need a new transmission. Torque converter issues. The shop stated that they repair / rebuild almost three chevy / gmc trucks like my truck a week with the same transmission problem. I still owe on my truck and shouldn't have to pay almost 6K for a transmission that is known to be an issue from the start of factory build. I own many older model gm / chevy vehicles and only had one other issue with one which also had a known recall issue.

The truck completely shut off while making a turn in town. I didn't have any control of the truck, steering or braking ability. In a attempted to restart the truck or regain steering and braking, I cycled the key to no avail. I then urgently tried putting it into neutral, and cycling the key again. The truck started and I regained control. In the 5-10 seconds that passed while the vehicle was out of control, the vehicle traveled over the curb and then onto the sidewalk. It is miraculous that I didn't cause an accident or cause injury to pedestrians. I was shaking. This event was the scariest thing that has ever happened to me in a vehicle. A blessing for sure. In not the clearest frame of mind, I drove the vehicle back to my home. It is parked and I won't drive it until it is repaired. Upon getting home and calming down, I googled this event. The Google search indicated that this scenario is very common in gmc trucks between 2014-17. The cause is apparently faulty battery cables and/or corroded grounding points. I do not understand why there isn't a recall or safety bulletin to inform vehicle owners of this issue. I could have easily killed someone. I passionately feel that action needs to be taken on this series of gmc trucks to prevent a deadly accident!

All power shuts off while driving. The transmission dis-engages, the power steering stops working and the infotainment system turns off. The power steering powers off even when sitting in a parking spot while everything else is on. I've owned this truck since 2019 and this has always been an issue, especially when taking a left through an intersection. I keep checking for recalls, but nothing shows up and I find that extremely hard to believe. I'm contacting you now because the issue has gotten worse, everyday worse.

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.

Truck loses power engine dies while driving after turning at slow speeds. Engine will restart after a few minutes like it never happened does not show any DTC codes or check engine lights. It is intermittent with no advance notice very dangerous to drive. Seems to be a common problem for all GM trucks and SUVS from 2014 - 2017
Electrical system, Apr 3, 2023
The electrical system has intermittent issues with connection to the battery due to the location of the ground connection from the battery. The ground connection is screwed into the under carriage (near wheel well front passenger side) and left exposed to the elements. Grit and grime build-up over time caused an interference with the connection. The safety issue is the vehicle lost power without warning and while driving causing the vehicle inoperable, including no power steering. Other symptoms include stabiltrak and park assist errors displayed while A/C & radio resets during intermittent power connectivity. Cleaning the ground connection wires & screw solved the immediate issue. This video explains it all, including where the issue is located and how I was able to fix the issue to restore power: https://youtu.be/KrSJJUUo9FU

My truck lost all audio including radio, turn signals and seat belt warning chimes. I feel this is a major safety concern not having a seat belt warning as well as an open door alert. The dealership notified me there is not a recall on the 2015 model and I would be charged for any and all labor.
