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.

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.

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.

I own a 2017 Silverado 1500 ecoTech V6, 6L80 transmission, 91500 - over the weekend, I started having an issue shifting from 3rd to 4th. I noticed the transmission was over 190 degrees, as high as 230 degrees, then cooling back to 194. When attempting to shift from 3rd the 4th, it will start, then return to 3rd. It will do so 4 or 5 times until eventually skipping 4th and going to 5th. This happens when the transmission fluid is cold, 80s or when fluid gets to 190+. I called the local Chevy deal, who told me there weren't any open recalls for my VIN and that the diagnostics would be $190 which may or may not be a software update. They would not know until after the disanostics.

The six speed transmission 6L80 failed with less then 60k miles and before it's first service due at 72k miles, I have already had the transmission repaired so the original transmission components are not available for inspection. My transmission failed when I was driving across the Coronado bridge in San Diego CA. This bridge has no shoulders to safely pull over. I had my truck towed to Cummings Chevrolet in National City CA. and they confirmed the transmission needed replacing. Yes the check engine light did come on but it was already too late to save the transmission.
