1. The vehicle's transmission does not operate consistently and safely. 2. At times, the transmission will not engage, and this has placed my family in very dangerous situations when changing lanes. 3. At red lights, at times, the transmission will not engage to drive. 4. When slowing in traffic at times, the transmission will not adjust to the slower speed, although the operator is applying the brakes. Then, without warning, the transmission will engage the higher speed, almost launching the vehicle forward suddenly, potentially into another vehicle or person, depending on the situation.

approximately, on or about [XXX], while driving our Chev Silverado, VIN as noted [XXX] ) started to experience transmission issues when i started from a stop sign and it started hesitating upon acceleration, jerking (gears not meshing correctly every time i had to stop). This included delayed engagement of gears, roughing shifting, slight slipping of gears, at times i could smell a burning like smell, (No leaks noticed on transmission anywhere and no warning lights coming on to warn about Transmission problems). On Jan 23rd, 2026, i took it to B&F automotive had mechanic check fluid level and do drive test with me. Fluid found to be good. I could hear a slight sound like high pitch sound at times, only last few seconds randomly). Mechanic suggested i put some fuel system cleaner in and 90 Octane to hopefully clear the system. dealer also suggested this just as a suggestion though they found no apparent issues during prior service oil change I just had dealer do a 27-point inspection with oil change and they did not notice issues. Since purchase of truck in 2019, from dealer, all services have been done only by dealer (Woodland Motors). we had bought extending service warranty with vehicle.

Bought the truck brand new, after 20,000 miles started vibrating. Took it to the dealership said it was the transmission shutters. They changed the fluid. At 50,000 miles did it again, they said GM came out with a thicker fluid, but it in there. Was fine for a while. At around 135,000 miles getting the vibration again. Also, at 140,000 miles cylinder 8 misfiring. Took it in and they tore it apart and said cylinder 4 and 8 lifter failure. Damage to cam and bent rods. Had to replace all lifters, cam and rods. Cost over $10,500, but had BG warranty used that additive every oil change so BG covered $4,000. I went by the oil life indicator on the truck to determine when I needed to change it, but apparently for engine for life you have to change it more frequently at 6,000 miles, so they wouldn-??t cover that part.

I am having the exact transmission issue for this truck that has been recalled, but when I call to get it serviced, I am told "there isn't any unrepaired recalls. This issue is persistent and unresolved. Please look into this and potentially recall the transmission issue. This truck has constant shifting troubles form 1st to 2nd with shuddering.

While driving on Highway 35 in Austin, Texas, my vehicle's transmission unexpectedly failed, which placed myself and my passengers in a precarious situation. The vehicle became inoperable on the side of the highway, necessitating that my passengers and I manually push it while traffic was actively flowing. This mechanical issue occurred without any prior indication. Through my subsequent research, I have observed that this particular problem appears to be a recurring concern with this model of vehicle.

Transmission went out while driving the vehicle and left it stuck in the middle of the intersection we had to push it though traffic. It had no forward movement. Would only drive in reverse. No warning or anything just made a clunk and wouldn't move any further.

- Lolo, MT, USA

The transmission started to shutter at 94,000 miles. Gwatney Chevrolet quoted $7,500 for a new transmission replacement. Had an in independent shop quote $4,670 for a reman transmission. I have only towed 2,000 lbs at a time in the past. This is the 1st time towing a 6,000lbs camper. It was only driven 800 miles with the camper in tow. The vehicle only has less than 95,000 miles and my transmission is shuttering and has metal shavings in the fluid. Needing a replacement at this time frame and mileage is ridiculous.

Transmission failure, I had to have the transmission replaced and no longer have it for inspection. I was on a one lane highway in Franconia NH with guardrails on each side, and no phone reception. Traffic was trying to get by me including tractor trailers, we were horrified and couldn't get out. these 6L80 transmission in the Chevy Silverado, come to find out, have been failing for a long time. 2 of my friends lost there's also, all of us were between 100k-115K miles. The transmission shop I went to, and others I called said they can't believe there was never a recall, they get many of them. Zero warning, just quit. I take exception care of my vehicles regarding maintenance, always early, these are to expensive to repair when your on a retired budget.

Premature engine failure specifically the lifters failed and the push rod failed causing the vehicle to become unusable and stranding the operator. Also transmission surges and slips causing unsafe driving conditions

I was driving to work last Monday when my truck entered a lymph mode. It would only let me go 40mph, when I was on a road that allowed others to go 60-70mph. I had traffic behind me as well. As I made it closer to work, the truck would only rev up. It left me sitting in a median with traffic going past me. Thankfully, I was not hit. I had to cut the truck off, wait several minutes, then start it back up to limp it to a safe spot where I could have it towed. I had it towed to a transmission shop. Please note* I have done the regular transmission maintenance on this vehicle as well. This shop done a diagnostic test on it ($95 +tax). It was a complete transmission failure. They told me this was due to the torque converter. General Motors, GM, programmed the transmission torque converter to kick on in 2nd gear which causes it to overheat practically everytime it drives. The same transmission shop said they rebuild 3-4 of the 6L80 transmissions a week. I have a 2017 chevy silverado with a 6 speed transmission, the 6L80..... This is an issue that GM should be held liable for. The transmission rebuild will be $4500-4800 + tax. Thank you to whomever reads this. I could really use help. My email is [XXX]. Phone number is [XXX]. I can provide rebuild cost and receipts when needed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There is a faulty weld on the radiator of my 2017 chevy silverado 1500 LT that cracked and began to leak coolant. Dealer stated that this is a common issue and there was no other remedy but to replace the radiator and coolant lines. i have seen bulletins and warranties for earlier models but the issue is still there.

- Big Bear Lake, CA, USA

While driving my vehicle, with around 85,000 miles, the engine suddenly began running rough and felt jerky and sluggish. This was concerning and potentially dangerous situation, as the engine failure happened while I was travelling at high speed. A sudden loss of power on the highway put me and other drivers at serious risk. The check engine light came on, so I pulled over as soon as I could safely do so. Shortly after, the light started flashing, so I shut off the engine and contacted the dealership service department. They advised having the vehicle towed in for inspection. Prior to this event, I had not had any issues with the vehicle nor had the check engine light come on. After looking into it, the dealership initially suspected a thrown rod but said they wouldn't know the full extent of the issue until they could tear down the engine. Upon further inspection, they determined that the lifters had failed and would need to be replaced. The dealership has performed all regular maintenance and oil changes on my vehicle. When I asked what could have caused this, they explained that it's a known issue with these lifters and engines - one that Chevrolet has experienced for years, even in models prior to my 2017.
