2018 CHEVROLET SILVERADO 1500 Complaints

My truck has had transmission issues since we purchased it. At 79,000 miles the factory transmission finally went out and needed replaced. The truck currently has 81,000 miles on it and is already having transmission problems with the rebuilt parts. Background: the truck began having hard downshifts since purchase. Over the course of our ownership, we noticed it started struggling with shifting from 2nd gear to 3rd and 3rd gear to 4th. Constant "clunking" and shuttering when trying to shift. Approximately November of 2024 the truck suffered from the known GM transmission failures. It was almost "skipping" upon acceleration and had a very hard time with cycling between gears. The transmission began making a sound comparable to a normal operating diesel truck (almost sounded like the turbo engines upon acceleration). The truck was sent to the dealership and the transmission was replaced. However, since this replacement we are now experiencing similar symptoms to the previous transmission. There is a very hard downshift, there is clunking sound when the truck is trying to go from 3rd to 4th, and the truck has a noticeable gear burning smell when driven long distances.

Transmission Failure & Torque Converter Clutch Failure, Less than 90,000 miles on vehicle. This is a known issue with this year and model truck that GM is aware of. It has been inspected by the certified dealer and they are aware that this is a known issue. I don’t tow with my truck or do anything but drive it regularly. I was Quoted $8,900 with a $2,000 Core reimbursement.

I was driving on the interstate and then all of a sudden my vehicle started shaking while driving and by the time I got home in less than 15 miles, the truck was producing huge clouds of smoke out of the exhaust. I took it to a dealership and it was determined the lifters were bad, less than 6 months after I paid off my vehicle and the extended warranty expired. In repairing the lifters it was determined there was a misfire in cylinder 6 which in conjunction with the lifter failure, it damaged rods and pistons to such an extent full engine replace was deemed necessary. I had every maintenance and inspection done on time since the purchase of the vehicle by a local Chevrolet dealership and there apparently was no warning or concern that my lifters were going to imminently fail and/or cause extensive engine damage. My truck was in the repair shop for nearly a 1 year while I waited for a new engine Chevrolet agreed to pay for half of an engine even though I was out of warranty by a few months, but I was under the mileage on the warranty by 30k miles. The truck was not heavily used. Most miles were highway interstate miles from long road trips, but the vehicle largely sat undriven most days of the week for a couple years leading up to the engine failure.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving 35 MPH, the transmission failed to operate as designed and the vehicle started losing motive power. The contact stated that the vehicle returned to normal functionality afterwards. No warning lights were illuminated prior to the failure; however, the check engine warning light illuminated after the failure and remained illuminated. The vehicle was taken to an independent mechanic and was diagnosed with transmission failure. The failure persisted and the vehicle remained at the residence unrepaired. The manufacturer was notified of the failure. The failure mileage was unknown.

Tailgate came open while driving and I lost items in the truck bed. This is the second incident. I had double checked to ensure it was latched before driving.

Have had 3 rear door actuator locks fail. Refer to complaint 11538814. Will be able to upload files at request.

Purchased this vehicle from a used car dealership 2 months ago. Now the transmission seems to be going out with 132,000 miles on it and funny noise from the transfer case. I have researched and found numerous complaints about the drive train on this vehicle and as a disabled veteran I don't have the funds to have it fixed. How can I get a recall in place for this issue?

Entire system (everything) shut down without warning, sometimes kick back on, and other times not at all. Extremely dangerous as it will occur no matter traveling on highway or turning a corner in a parking lot. There are discussion boards in which many people have experienced this problem and clearly it is because of "Bad Battery Cables" and common within the 2014-2018 models. My truck is currently in a dealership garage to have the cables replaced and I have to have a rental car while the cables are on backorder for 5 to 10 days (maybe longer). How is this not a "recall" when so common and so dangerous? Dealership could see in a diagnosis that power had been lost and communication lost, over and over and over. There has never been a dash warning light come on at all.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving at various speeds, the contact stated that the vehicle felt like the transmission was slipping. The contact stated that the transmission was shifting abnormally. Additionally, while the vehicle was stopped and idling with the brake pedal depressed, the RPM was fluctuating, and the vehicle was moving unintendedly. The contact stated that while attempting to accelerate the vehicle was jerking. The contact stated that the check engine and traction control warning lights were illuminated. The vehicle was taken to the dealer however, the dealer was unable to determine the cause of the failure. The dealer replaced the serpentine belt however, the failure persisted and became more persistent over time. The vehicle was taken to a certified mechanic who retrieved a DTC code for engine failure. The mechanic referred the contact to the manufacturer for assistance. The vehicle had not been repaired. The manufacturer was made aware of the failure and confirmed that the VIN was not under recall. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was 92,000.

Transmission vibrates when it approaches 35 mph and 65 mph. The vibration feels like rumble strips and last for 3 seconds
