2018 CHEVROLET SILVERADO 1500 Complaints

Transmission failed at approximately 120,000 miles. All maintenance had been done and 90% of miles on vehicle were highway miles. Appears as though there's a thermostat mounted on the exterior of the transmission that is prone to failing around the 100,000 mile area, and when this part fails, there is no transmission fluid circulating to be cooled, so the transmission gets so hot it fails. There are tons of youtube videos from many GM owners that have had to spend thousands and thousands of dollars to replace the entire transmission, when General Motors knows of the faulty part.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the contact attempted to depress the brake pedal; however, the brakes failed to engage as needed. The contact stated that the more consistently the brake pedal was depressed, the more the brakes failed to function as needed. No warning light was illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the brake vacuum pump needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 90,000.

Truck suddenly started slowing down and smoke came from the tailpipe. No warning issued before the failure. Transmission replaced in January of this year also.

Had to replace rear end now transmission is starting to act up like might be going out (the truck started by like having a shake as you drive ot not for long period just every so often to when i gave ot rhe gas the really loud whinning noise let off gas it stopped )looked up to see if any others and many others with the same model as mine is having same trouble as I am and have not seen any recalls,but many people have been having same issues .

My transmission had a history of failing trans symptoms, all documented at the dealer from 10,000 miles until it ultimately failed at 127,000 miles. Those symptoms where a down-shift thud, confusion to what gear it should be in, shuddering, shaking and fluid temp running hot without towing a load. Was told by the dealer this was all normal, that the transmission was "still learning". Eventually the trans failed and was towed to the dealer. Dealer said that pieces of the torque converter were found in the fluid and building up in the filter, ultimately clogging it. I had all my recommended maintenance done at the dealer over the life of the truck. Once the trans failed I had an independent service center rebuild the trans, not wanting the same remanufactured trans that failed put back into my truck without any improvements made. No warning lights ever came on.

Transmission failed and truck shut down mid road while going uphill. Shifting jumps when gears are switched and power jumps and goes down while stepping on gas pedal. At first it showed a check engine light but because i was traveling i had to skip and tried turning on again. It happened at least 5 times while on the road that day and now shifting is messed up and jumps while stepping on gas. I inspected and took to a mechanic for an inspection and said need a new transmission unless there is a recall because it happens to many 2018 chevy silverados 1500.

We just purchased the truck from a Chevrolet dealership 6 days prior took it on a trip to Missouri. Truck transmission shuddered then downshifted nearly causing a rear end accident behind us. Luckily the driver was attentive and did not hit us
