On Saturday Aug 6th, 2022 my girlfriend and I were driving in my 2018 Chevy Silverado and the car just came to a complete stop really hard. Once the truck froze up, the car would go FOWARD but very slow, jerkish, and sluggish. We were almost hit by three cars behind us when the truck froze up. The truck was towed to the dealership where they diagnosed the truck with METAL SHAVINGS in the TRANSMISSION. And the engine light came on four weeks after I bought the vehicle last October. This time-??. There was NO engine light on. Nothing displayed on dashboard.

The transmission failed at 81k miles. Upon doing some research, it sounds like this is caused by the wrong transmission fluid that was installed by GM, not myself, the owner. If known about early enough, flushing the transmission 3 times and replacing with the newest transmission fluid is to correct the problem. I was not notified of this 'fix' and the transmission is already damaged to the point where it must be replaced.

The transmission failed. The truck had heavy shifting and the transmission needs replacement. The truck was no longer safe to drive. The problem was diagnosed by a licensed mechanic shop. The check engine light came on as well as the service stabilitrak light that came on the same day as failure.

For months this truck as stuttered while driving. Eventually one day the RPMs would shoot to 3500 when trying to shift gears and would struggle to shift. After having the spark plugs replaced and a tune up ($660 later) it started randomly just losing power to the engine while driving. All electrical still on but no power to the engine. I would pull over and turn the engine off and restart and it would be fine again. This continues to happen with no explanation. Always acts fine after I stop the care and turn it back on again. Nothing comes up on a scan for issues. Mechanic can't figure it out and now it isn't "acting up" when the transmission guy drives it and he doesn't know what's going on either. It's not safe to drive on the HW if its going to just randomly lose power. We checked with another transmission shop and he said they have two chevy Silverados in line for something similar. That made me look to see if there was a recall and led me to make this report. Chevy should look into this and do a recall.

Transmission shifts out of gear spontaneously while driving and warning light comes on for -??transmission hot idle engine-?? forcing the vehicle to become inoperable unexpectedly without allowing the vehicle to drive forward or reverse to get to a safe location. Transmission temperature gauge rises quickly to 280 degrees in less than an hour of normal driving before overheating. Multiple General Motors dealers and General Motors headquarters have been unable to diagnose the problem and provide a solution despite multiple attempts and several thousand dollars in repairs including a completely new replacement transmission. General Motors first recommended the dealer to hook battery cables up to the transmission which did not fix the problem and in fact caused the vehicle to not start several times. General Motors then recommended the dealer replace the transmission entirely. Despite replacing the transmission, the same problem exists and the vehicle shifts out of gear while driving reporting an overheating transmission. Problem still occurs today 3/25/22 and vehicle becomes inoperable unexpectedly and suddenly while driving due to overheating transmission. General Motors is unable to diagnose the problem or provide a solution.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle would not properly accelerate while depressing the accelerator pedal with the check engine warning light illuminated. Additionally, while depressing the brake pedal, the braking system malfunctioned causing the braking distance to be extended. The cause of the failure was not determined. The manufacturer was contacted and notified of the failure. The local dealer was not notified of the failure. The approximate failure mileage was 96,000.

While driving my transmission will shudder and the vehicle will lose power causing the vehicle to slow down abruptly. It also will shift very hard making a loud noise.

- Sapulpa, OK, USA

The transmission started shifting improperly at 40k and the fluid gets to hot

Transmission noise -something loose only 60k miles

When entering traffic, upon acceleration the truck stalls, and shutters. Going into traffic a vehicle had to maneuver to avoid collision with me. I took it to the dealer and they said transmission should get a flush and transmission oil was low. At 60,000 and out of warranty I paid for service and they said it was good now. it still continues. I can-??t afford to take it in for service and pay again. From searching online customers state the dealer representatives all say it-??s normal for truck to do that. Also, others say transmission (6l80) and/or torque converter is the problem. Again being without warranty I cannot afford to take it in and pay to just get that -??it-??s normal for the vehicle to do that.-?? A vehicle that stalls IS a hazard for the driver and for others on the road. Especially entering highways and heavy traffic streets. The main reason is we never know when it will stall or when it will accelerate what I believe is properly.

The torque converter failed internally allowing the torque converter clutch to shudder. The fluid exchange has already been done on RO#587959. Vehicle had 40k when torque converter was replaced. Issue arouse after a road trip to Houston Tx and progressive more at various speeds. James Wood dealership replaced the torque converter since it was still under power train warranty. When I researched online, I realized that this is a common problem within the 2014-2018 Silverado models. I hope I that after the dealership replaced this defected part I don't experience additional mechanical issue related to this faulty part.

The transmission stopped working randomly on the highway after being driven for 45 minutes perfectly fine. Thankfully this happened near a stoplight so the traffic on the highway was going slower than normal otherwise it could have been very bad. Local mechanic confirmed that the transmission was no good and has ordered a replacement. There was no indication of the issue prior to the failure. No lights came on to indicate that there was an issue.

While driving this truck i get a severe shudder at various speeds and now its not shifting gears correctly. I have been told there is a big problem with these 6 speed transmissions ans torque convertors.

- Jackson, OH, USA

The engine gave out at 60k miles. Only covered buy the extended warranty I bought. the transmission thunks on downshifts. The exhaust adaptive valve started making a terrible noise at 40k miles. I took it to the dealership for them to tell me my extended warranty doesn't cover it and to buy an aftermarket exhaust because it would be too expensive to replace it. I think they quoted me at $1200

I was on highway 65 coming out of Rocklin Ca going back to Yuba City Ca. The Chvey Silverado with out any warning it just lost power and I had to pull over. I am glad I was on the slow lane. If I was on fast lane with a big rig behind me. It would have been bad. After pulling over the Eng Light when on for the first time since I have owned the truck. Not any time before. I thought if a family with children was in the fast lane and this happened it would not be a good out come. I had it towed to my home the chevy dealer was close. On July 18 I had it towed to the dealer I had the truck towed to Wheeler Chevrolet In Yuba City They replace the engine computer and the tranny computer. And to day Aug 1, 2021 they said they would fix the tranny. I am wondering if they know what they are doing ? This is very disturbing I am very apprehensive about the safety of the truck if this were to happen again !!

Radiator started leaking at 40,000 miles. Leaking at a weld where tube connect to side tanks.

- Hermitage, TN, USA

The transmission clunks and slips a lot.

- Shakoprr, MN, USA

Radiator developed a leak as described in General Motor's Service Bulletin PI1513F dated January, 2019. Safety was put at risk due to having a vehicle which could have a sudden radiator failure and permanently damage the vehicle. The Dealership I had my radiator replaced at would not state if they have had this issue occur often. No warning lamps or messages prior to the radiator losing 1.5 gallons of coolant. My first symptom was the engine overheating.
