From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at …

The 6-speed automatic transmission (6L80) developed a severe shudder during normal driving. A service center diagnosed the problem as torque converter clutch failure; the torque converter sheds metal debris through the transmission, so the transmission now requires a full rebuild quoted at approximately $6,000. The failure occurred at approximately 92,000 miles in October 2026 (incident date is approximate). This is a widely documented failure pattern on GM 6L80 transmissions. Loss of reliable power delivery from the transmission is a safety concern. No crash, no injuries, and no fire occurred. The vehicle is available for inspection upon request.

In August, 2019, at 93,672 miles, GM covered a lifter failure on our 2015 GMC Sierra, V8 AFM engine. Only the left side was repaired. Now, in 2026 at 130,000, the right side has the same issue and needs repair. The estimate to repair is $16,697. This is a known issue and a safety concern.

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.

Power steering seems to be lost for a second or two at low speeds turning. Happens multiple times a day.

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)

See attached document for complaint.

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.

My 2015 GMC Sierra 1500 SLE has the 6L80 transmission. While traveling on the interstate with my fiancé, the transmission failed. It was towed to a garage and they informed me that it needed to be replaced.

Another GM truck AFM failing. It failed at 70,000 miles causing P0307 cylinder 7 misfire. No aggressive driving just commuting to work. Truck just got done with a new oil change. It's another to add to the hundreds/thousands seen on Reddit threads of all 5.3/6.2 AFM/DFM that this organization turns a blind eye to.

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

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.

During day to day driving when the truck is accelerating from a stopped position there's a massive clunk or hard shift from either 1st to 2nd gear. have also heard similar complaints from other 2015 sierra 1500 owners saying the transmission is having a hard shift on acceleration from a stop. Have seen possible issues with the TCCM

Tranmission is shuttering and not wanting to shift right

The contact owns a 2015 GMC Sierra 1500. The contact stated that while at a complete stop and attempting to shift into reverse(R), Drive(D) or park(P), the gear shifter was stuck, and the contact had to go underneath the vehicle to move the shifter cable into the intended gear.

The contact stated that upon returning to the residence and attempting to park the vehicle, the gear shifter failed to remain in the intended gear and was moving unintendedly. The vehicle was not repaired. The dealer and the manufacturer were not contacted. The failure mileage was approximately 225,740.

I remote started my truck. I got in about 5 minutes later. When I shut the door the rear window, passenger side of the power sliding window blew out. GM says my VIN is not affected by the recall but my truck shows that it should have been part of the recall or customer satisfaction program. N192265660 Rear Window Defroster Thermal EventS

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.

The GMC Sierra 1500 started a knocking sound. The collapsed lifter on a AFM cylinder bent a push rod which led to cam failure. Metal fragments are throughout the oil system.

Loses power steering when vehicle is low speed or stopped. Same details as safety recall 14743 for 2015 gmc sierra.

The contact owns a 2015 GMC Sierra 1500. The contact stated that while driving at an undisclosed speed, the vehicle lost power steering functionality and shut off. The contact was able to pull over to the side of the road even though the steering wheel was difficult to turn. The contact was able to restart the vehicle after several attempts. The contact stated that the failure had recurred while driving. The contact stated that the message "Service Stabili-trak" might have been displayed. The local dealer and another dealer were contacted and confirmed that the VIN was not included in NHTSA Campaign Number: 18V586000 (Steering). The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 130,379.

While driving the vehicle at approximately 40MPH the motor made a tapping sound, I was able to pull into a parking lot and have the vehicle towed to the dealer. The dealer told me that the vehicle was out of warranty and appeared that under initial inspection the would have to rebuild the motor due to a lifter failure at the estimated cost of $18,000. I had the vehicle towed to a reputable repair shop and after the did a tear down to the small block they determined a bent push rod and broken lifter, all pushrods and AFM lifters were replaced at the cost of $10,754. dollars as invoice shows. The issue occurred again on 10/25/25 causing catastrophic failure that will cost me a complete engine replacement.

This occurred 5+ years ago. Coming home one night I had a sudden loss of power with the truck and barely made it home. Was able to limp the truck to the dealership the next day and was told that one side of the engines lifters had failed. Prior to the failure I had noticed a ticking sound coming from the engine that was becoming increasingly more prominent. It was several thousand dollars to repair. Fortunately the failure occurred near home, not on the freeway where I could have been dodging cars while trying to limp the truck to the shoulder. Some online research while the repair was being done revealed that several other owners with the 6.2L engine had the same problem. When I mentioned it to the dealer the response was that they had no bulletins from GM on the issue and I was stuck with the bill. Got the same response a year or two later when the torque converter on the transmission went out. The reason I am reporting it now is I saw that GM is recalling 6.2L vehicles with lifter issues but not back to 2015 even though the issue appears to go back farther than that. They claim it's limited to a specific run of engines for the recall. They have been having various lifter problems for many years that have put drivers in danger when they fail but refuse to acknowledge it. As for the repair they made to the engine I've driven another 70 K miles and the ticking has started again. I fear another failure. Please note that the date previously given for the incident is my best gue

The temperature sensor in the transmission is faulty leading to hard/delayed shifting, shuttering, and vibration

Transmission failed at 110k miles roughly. Safety was put at risk due to this happening on a highway. Yes, transmissiom was replaced by a local repair shop, the means of failure was identical to thousands of vehicles in this model year failing prematurely. No it wasnt inspected by the dealer. No there was no warning light, we were going up a hill and it failed.

The contact owns a 2015 GMC Sierra 1500. The contact stated the front passenger’s seat belt was difficult to buckle, and it recently started unbuckling while a passenger was seated in the passenger’s seat with the seat belt buckled. The contact stated that when the seat belt was unbuckled, the seat belt warning light was illuminated. The contact had not taken the vehicle to a local dealer or independent mechanic to be diagnosed or repaired. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 170,000.

Lifter and camshaft failed

Push rod failure in #4 cylinder at 104,000 miles. Bent push rod. Possibly due to AFM.

I have owned 4 of these trucks in my lifetime ranging from 2007-2015 all equipped with the same drivetrain. 5.3l engine and 6l80 transmissions. All have had the same failures. The engine afm system particularly the lifters fail which in turn destroys the camshaft and destroys the engine. More importantly the transmission torque converter fails sending debris through the whole system causing a sudden loss of drive. This happened while driving down the road and was a safety concern for myself and others. This time it costed me $6500 to replace the transmission. All of the trucks I have owned experianced the same failures how is this not a problem?

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)

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

Starting vehicle in parking lot and backing out of parking space. Brakes failed and truck continued to roll backwards almost hitting a pedestrian. I was able to stop hard on the pedal and stop the vehicle. This has happened several times. I have a steep driveway and backing down to the street the brake pedal will unexpectedly have little resistance and the truck will continue to roll into the street almost hitting oncoming traffic.

The mount for the rear shock absorber has completely rusted away on the driver side. The tube is gone now that it was attached to. This is a way to new of a truck for that kind of rust to happen I have been around 40 year old trucks that this never happened to.

Brake pedal pivot nut came loose and fell off while driving.

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.

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.

Fuel pump losses prime overnight. gas sprays from fuel line onto top of fuel tank. problem was brought to my attention by a repair shop.. found several instances listed on YouTube of this problem

I was driving pulling an empty small U-Haul trailer and attempted to pull in to a fuel station when my brake became impossible to depress. I barely was able to miss hitting gas pumps and ran down into a ditch before the truck stopped. I informed the dealership where I had just purchased this truck used. I took it to their service department and I was told there was no issues with the brakes. They had to have this recall bulletin in their computer system yet failed to make me aware or to perform this recall or report it to GM. The problem continues to worsen to the point I am scared to drive it. I almost rear ended another car at a stoplight yesterday because I was unable to depress the brake pedal. I stood on the brake and heard an electronic sound but finally came to a stop.

I am writing to formally submit a serious safety complaint regarding the transmission in my vehicle, which nearly caused a life-threatening accident while driving under normal conditions. While traveling on a two-lane rural highway, I was attempting to climb a steep hill when the transmission suddenly began to slip. My vehicle lost power mid-ascent, despite steady pressure on the gas pedal. The RPMs shot up erratically, but the vehicle failed to accelerate. As I began to crest the hill, the transmission completely disengaged, forcing my vehicle into a free-roll situation. The danger escalated quickly. As I started to descend the hill, I attempted to downshift to control my speed—but the transmission would not respond. It slipped again, and I was essentially coasting with no engine braking. An 18-wheeler was behind me, approaching fast. I could see it barreling toward me in my rearview mirror, and I had nowhere to go. With the road shoulder too narrow and no pull-off in sight, I had to veer dangerously close to the edge to avoid being rear-ended. I truly believe that if the driver of the semi hadn’t taken evasive action, I would not be here to write this complaint today. This transmission failure is not only unacceptable—it is a critical safety issue. A vehicle should not lose all power and braking control during normal highway driving. This is not just an inconvenience or a performance issue. This is a defect that puts lives at risk. I am requesting that this transmission be
