UNKNOWN OR OTHER
Unknown system Tailgate lowered by itself. It was up when we got in and left and was down when we got to our destination. Luckily the only thing that came out was a golf towel and not the two sets of golf clubs as well. I believe this is a problem on other GM vehicles Has not been inspected and no warning lamps

POWER TRAIN, SERVICE BRAKES
I was driving along about 45 mph and the truck was cruising in overdrive so about 1500 rmp on tachometer. I hit the gas to climb a hill as truck started to lose speed and when it tried to shift out of od to pick up speed the brakes seemed to slam on and I skidded to almost a stop. This has happened several times when climbing a hill or anytime I have to pass a vehicle or accelerate from out of overdrive. The dealer could never seem to get it to reproduce during test drive. They recently said there is a service bulletin for this exact issue and are waiting for a new valve body for transmission. My service records show I had a new valve body installed last year due to transmission pump bearing coming apart internally. The valve body is only a year old. But this is a very dangerous situation. I have to drive my truck for work and I have to be really cognizant of how hard I touch the gas and what gear I am in. If this happens to anyone while on the freeway and a semi or another vehicle is too close their truck will downshift and lock brakes and it could cost a life. It only happens under these circumstances but it has to be a recall. A service bulletin doesn't get it as someone has to have it happen for it to even be looked at. I have to drive my truck as I do not have a choice. But a service bulletin shows that GM I'd aware of the issue but they are unwilling to do a recall. A lotnof silverados are on the road and inwould hate for anything to happen. It could ruin a lot of lives.

SUSPENSION, WHEELS, STEERING
I purchased a used 2021 Chevrolet Silverado from a dealership 5 months ago. Almost immediately after purchasing the truck, I would hear and feel an intermittent pop that originated from near the floor of the front passenger side. The sound became more frequent and would happen mostly when making sharp turns but also when making softer turns. I took it to the dealership to investigate. They had it for a week and supposedly examined the entire vehicle. They were able to replicate the pop sound when driving it but were unable to diagnose the problem. They claimed that sometimes trucks just make noise and assured me that the vehicle was safe to drive. I asked how they knew it was safe if they didn't know what the problem was and how was I to know that whatever is causing the sound isn't causing internal damage. The service manager again assured me that the certified mechanics looked at every detail of the vehicle and found nothing to be concerned about and sent me on my way. After taking the truck home, I continued normal use of the truck, taking it on 3 long distance trips on the highway. The sound continued as it had before, occurring intermittently when turning. 2 days ago, I was backing out of my driveway. I heard a very loud pop and got out of the vehicle to find that the front passenger wheel had completely broken at the ball joint of the control arm and was lying nearly flat on the ground, held suspended by the brake line and CV boot and other attached components. The truck was towed to the dealership, where it currently is. The service manager told me that the mechanics did everything that they were supposed to have done and that unfortunately this is a mechanical part that can fail and that he has seen this issue in 7-8 other vehicles like mine. If this is a common problem, there should have been a red flag when presented with this issue. If this would have occurred on the highway at a high rate of speed, my family and I could have been killed.

ENGINE
A couple of days ago, noticed some coolant under my truck. Took it to a dealer who informed me that the radiator has a crack in it. The truck has just over 53,000 miles on it and the warranty doesn't cover the radiator after 36,000 miles. We keep it serviced as normal and there hasn't been any extreme weather here in Oklahoma lately to explain the this away. Just irritating to pay the kind of money you pay for something that has this kind of issue already.

The contact owns a 2021 Chevrolet Silverado 2500.

ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
1. Trucks start/stop delays. When in traffic or crossing over lanes the truck fails to turn back on/start. When the truck does turn back on, the truck jumped forward almost sending me and my family into on coming traffic. 2. When trying to start the truck the starter will turn over constantly not turning on the truck (motor is turning over). The starter will time out after about 20+ seconds. The starter does this when auto start/stop is activated, so we get stuck in traffic almost causing accidents.

ELECTRICAL SYSTEM
On Sunday, January 4th, the tailgate of the truck began unlatching and opening on its own. It has done this repeatedly since that date. Only unlatches when the vehicle is in park and unlocked. The electronic latch will continue to cycle (click) after the tailgate has initially opened. Exterior taillights and side markers flash as they should with each cycle. This issue is identical to the warranty recall issued recently for the 2020 through 2024 Chevrolet and GMC 2500 & 3500 trucks.

EXTERIOR LIGHTING
Factory LED headlamp was flashing rapidly like a strobe light intermittently before it failed. The lights are bright enought that it was not immediately obvious to me (the driver) that anything was amiss. Was noticeable when close to other vehicles in traffic and on open, dark roads, where the strobing affect as apparent on reflective signs. The unit later failed completely and is now backordered and so unavailable to replace. I'm forced to drive with no headlight. The unit was faulty and suffered from water intrusion, which was determined to be the cause of the failure by the dealership. The failure occurred less than three years after the vehicle was placed into service, though it could not be taken in for service until a week after warranty expired. It is not covered by any warranty, though headlights are typically a wear item and expected to be readily replaceable. Dealer-quote cost to repair is $2,300, making the repair to be likely inaccessible to many owners. I have a video of the offensive behavior.

ENGINE
"Cylinder 4 misfire" was the diagnostic code - the vehicle is currently at Millennium Chevrolet in Hempstead, NY. First attempt at a fix was the fuel injector - second fix is replacing the rocker arm. Emissions is still showing as an error. I was traveling to the dealership for repairs when the misfire became so bad that multiple alerts illuminated on the dash. I was in stop and go traffic at the time going 30 mph. Thankfully I was near a place to pull over out of the flow of traffic. I tow with my vehicle and just returned from a cross country trip - if this happened while towing up a grade in the western half of the country, I don't know what I would have done. Yes, the dealership confirmed the problem and it is under the powertrain warranty. I do not know if GM Engineers have inspected the engine, however, it has been in the care of a GM dealership and service center since [XXX]. [XXX] the check engine light illuminated for the first time, yet went off after .2 of a mile when I turned around to return home. I made an appointment with service at the dealership the next morning ([XXX]) and was on my way there when I no longer felt safe driving it and called for a tow truck. [XXX] - check engine came on and went off. [XXX] - check engine came on again. [XXX] - check engine - on the way to the dealership - service parking break, anti-traction control. This is when I pulled over because the vibration from the misfire of the engine became much worse. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On the evening of Dec 19th, our 2021 Chevy Silverado 1500 DuraMax with 19K miles on it caught fire, burned, and was declared a total loss. We were on our way to go pick up our travel trailer as were we leaving for a trip on Xmas with our 2 dogs and my brother-in-law. Smoke started billowing out from under the hood and within minutes the front end was engulfed in flames. I have pics/videos. We’re ok but that was a scary situation that could have had a different outcome. We could have been on the highway towing our trailer with our 2 dogs and bro-in-law and who knows how long it would have taken the fire department to arrive on scene on the highway. There were no warning lights etc. to notify us. The truck gets driven, taken care of and I had just driven it the day before. We’re not aware or have seen any recalls. All info is on our Chevy app. We filed a claim with our insurance, and it has been paid off now, but in reality, "our fault" in insurers eyes. No cause was determined. That being the case, GM has closed claim and say not liable for personal property lost in fire, as insurance didn't contact GM with any mfg defects and insurance has already paid off the truck. We are repeat Chevy customers. This was our 4th leased Silverado and we also have a Traverse. The lease on the burned-up truck was coming due May 2024. We way overpaid on the milage. We're not filing a homeowners claim for lost personal property as insurance has paid off the truck and we don't want to be dropped. My question is wouldn't this be under warranty? Should the truck not be replaced? We didn't cause the fire. Much more damage could have occurred. People and pets could have possibly been injured or worse. If we were towing our travel trailer, that would be another big loss. The truck is no longer "available". Insurance told me today it's being sold for parts, which honestly kind of scares me. I wouldn't want a truck part that was in a fire, damaged or not. Videos not attached.

ELECTRICAL SYSTEM, POWER TRAIN, UNKNOWN OR OTHER
Truck lost power and shut down without warning while driving in traffic. Happened twice on the way home from church with my family. First time truck shut off as we were turning across a busy intersection. Coasted off on to shoulder of highway. After several attempts truck restarted. It shut off again before reaching home. Has to call a tow truck. Has truck towed to local Chev dealer on New Years Eve. Dealer kept truck three days. Could not find problem. I picked up truck, drove home, truck shut off just before I reached my house. Coasted into driveway. Called dealer. Said bring it back. Waited two hours. Truck started so I drove back to dealership, approximately 15 miles. Truck shut off again without warning on highway in front of dealership. I sounded horn and flashed lights as I coasted across oncoming traffic into dealership parking lot. This was on Wednesday Jan 3rd. Friday afternoon dealer called and said that hey have not been able to isolate problem. Said they know they are losing communication between modules but don’t know where. The “fix” they claim is to take the cab off the truck and replace entire wiring harness! Cost is $6300. Truck has 48,000 miles on it. All highway and road miles. Can’t afford $6300 to repair a 2.5 year old truck. I am fortunate that neither me or my family were involved in a crash due to truck shutting off unexpectedly. This is a very dangerous issue.
