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.
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 !!
The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving 75 mph, the traction control and the transmission overheating warning lights illuminated. The contact was able to park on the side of the road for 30 minutes for the transmission to cool down. The contact stated while driving to his residence, there was an abnormal sound coming from the vehicle. The contact took the vehicle to the local dealer to be diagnosed. The contact was informed that the transmission control module needed to be replaced. The vehicle was repaired however, the failure recurred. The manufacturer was not informed of the failure. The failure mileage was 24,158.
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.
While driving highway speed on cruise control the RPM levels start jumping up and down and it feels like your driving over the rumble strips. It only last for a second or two at a time, but it does do it a good amount of times while driving.
When coming to a full stop, the transmission down shift really hard. It makes the vehicle jerk forward. It doesn't matter if you are going up hill/downhill or on a flat road. I took it to the dealer at 4K miles for this reason and was told it was a known Chevy issue but that they had no way of fixing it.I took it back a second time at 5K and was told the jerkiness and poop the transmission does is a GM defect design but that they had no way of fixing. Dealer said other owners have installed a 3rd party single piece drive shaft with angle spacers but that was not covered by GM warranty. Dealer essentially wanted me to fix the harsh shifting and clunkiness by going with an after market parts provider. A work around that has seem to make the issue more bearable is putting the truck in 'tow mode' it smooths the ride out but it tends to make the transmission run about 20'40 degrees hotter
The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving approximately 55 mph, a warning light indicating that the transmission was overheating illuminated. The contact pulled over and turned-off and restarted the vehicle and continued driving. The warning light disappeared. The contact took the vehicle to pendarvis Chevrolet company, Inc. (650 augusta rd, edgefield, SC 29824, (803) 639-8117) who flushed the transmission and removed the thermostat and plugged one line directly to the transmission. The failure recurred and the contact took the vehicle back to the dealer who then repaired the torque converter. The failure recurred whenever the contact would attach a load to the vehicle and the vehicle was returned to the dealer a third time however, the mechanic was unable to identify the cause of the failure. The vehicle had not been repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 59,000.
Failed to shift gears. Jerking and shaking. Bunning smell. Failed to move in drive or reverse. Check engine light eventually came on. Still has transmission fluid.
Transmission locked up and failed. Acted like it bound up. This happened during a normal shift sequence, acted tight then engine just kept over revving. Happened about 3-4 months ago. Dealer fixed for free. Said it was common. This happened right at 60K miles. Said if it happens again they will not warranty it as there is no fix for this problem. Suggested I buy another new truck. Next problem is my right front caliper has failed twice and needed complete replacement. It is now failing for the third time. This is seriously unsafe and crazy. I have only about 73K miles on this truck. Third thing is my chrome trim on my door handles has repeatedly failed. I was told by my dealer this is normal and it is not fixable unless I pay them. It is not normal wear and tear. The truck is babied and kept in perfect condition.
When I place the truck in drive in the morning or after the truck has been sitting for more than a few hours, the transmission engages hard, lurching the truck body foward. The dealership acknowledges the problem, but said there is no fix.
