While driving to work a month ago (3/19/25) I lost the power to accelerate out of nowhere. And my truck started making this noise, what I can only describe as a winding up noise while trying to accelerate. I was going 55mph on a busy morning commute. There were no warning lights. I pulled over and shut the truck off. Checked oil (even though it was changed a week or 2 prior). Oil was fine. Let truck sit for 10 mins then tried to turn back on, it started but had that winding up noise when just sitting in idle, the check engine light then came on after it was on for a minute or so. Ran codes at home, and truck started making an additional rattle noise on top of the winding up noise when had to be turned on. One code was the crankshaft position sensor, we changed that out. Then the truck wouldn't start. Taken to Dealership, and they said initially they found a broken connector to the engine harness. Fixed that then truck started but still making the rattle/clunk type noise and louder than at home so they continued diagnostics because they said the noise sounds like a rod knock, so rod either being bent/broken/slipping. Further diagnostics found that oil and coolant are mixed along with metal shavings through engine so new engine is needed.

I have a 2014 chevy silverado that I purchased brand new from the dealer. The truck just hit 100,000 miles and recently had a clunking noise from the rear undercarriage. After having it inspected, it has come to my attention that the frame is rusted and rear crossmembers are rusted out causing the rear shock mount to break, and I'm not sure if the frame is salvageable. After doing some research, I found a recall for my year silverado for the undercoating on the frame(not properly done from the factory) but my VIN is not in the recall. I'm at a loss being the year of the vehicle and mileage on the truck considering it might be undeliverable and unfixable

When I attempt to speed up or slow down my truck hesitates, and it's followed by a significant shake, like a shudder, and sometimes it just jerks, or clunks, like it's doing a very “hard shift” when the automatic transmission changes the gears. Sometimes it shifts so violently, I feel like I got hit by another vehicle. I've also tried to accelerate into traffic, and the truck hesitate and then abruptly and violently jerks into gear. It creates a big traffic safety issue! Other times the transmission shifts gears so hard that it slams the truck forward, and makes feels like I've been rear-ended.

Vehicle less than 150,000 miles and transmission hasn't held up. Vehicle isn't driven hard its my daily driver to work. Transmission temperature exceeding 200 degrees on a short drive, hard shifting into 1,2,3,4 gears. I have done my research looking into other people that have had this trouble and it has become a well known problem with these vehicles. Everyone is experiencing trouble from the torque converters to the gears, and clutches. Its terrible that we are spending 10's of thousands of dollars on a vehicle that will not even hold up to 150,000 miles. These transmissions needs to be recalled and replaced. I have also done further extensive research that shows that from the GM Bulletin you can find documentation that shows that the 6L80 transmissions have problems with this exact issue. This Bulletin was published in June of 2020. If GM has listed 13 different models of 6L80 transmissions in different vehicles that are having such problems. Why hasn't this been recalled to make it right to the customers who have these vehicles. We are being ripped of our hard earned money and left with vehicles that are extremely expensive to have repaired or forced to let them go back or have no option but to trade it in and still be left with lots to pay on these vehicles.

I purchased vehicle new 12/2013 and have had the vehicle to Chevy dealer after purchase due to hard downshifts and banging in transmission on shifting. Dealer claimed condition was a normal condition and would do nothing to remedy. This shifting condition stayed the same until the following event. 10/19/2021 driving northbound on I75 in Michigan at 75mph vehicle starts jerking and banging and starts losing speed. Tachometer is bouncing up and down between 1800-2300 rpm, transmission temp was 270 degrees. Vehicle is having transmission failure. I put transmission in manual mode and used 4th gear at 45 mph to limp into my destination. It was pitch dark, raining and very hard to see and I was concerned of being rear ended if I pulled off the side of the road and waited for a wrecker. The next day I drove the vehicle to a transmission shop, again using M4 to limp in as my brother in law followed behind with his emergency flashers on to alert others of a slow moving vehicle. The independent transmission shop inspected my vehicle and determined the torque converter failed and contaiminated the transmission, lines and cooler with metal shavings. They also commented they see several of these vehicles for the same problem, it's common issue they said. Mileage at failure was 124780. They rebuilt the transmission, replaced the torque converter and flushed the lines and cooler at a cost of 2755.00. GM should be held responsible to reimburse owners of these vehicles as they knew of these transmission issues and placed the occupants of vehicle at risk of injury or death if this issue caused a collision. I have attached documented complaint at GM when vehicle was new of clunking and banging in transmission and their answer was its a normal condition.

The truck is jumping rpms I've had many mechanics look at it and even switched out parts out. I was told told it could be 4cyl to 8cyl adapting now I'm being told the torque converter is faulty .. The truck gets stuck at a stop light or feels like a hard pull when slowing down and sometimes even makes a clunk noise.
