POWER TRAIN
The Transmission Oil Cooler line separated at the crimp joint from the rubber hose to metal pipe. This sprayed trans fluid all over my hot exhaust(fire risk) and caused and immediate loss of propulsion as I was accelerating to merge onto the highway. I was lucky enough to have multiple vehicles swerve to avoid hitting me. This defect left me on the side of the expressway.

POWER TRAIN
torque converter and transmission. For more than a year truck would lunge or jump forward when stopped at light or sitting in traffic, brought truck back to dealer several times for this problem each time they would tell me nothing wrong with truck. problems continued to happen and Truck started hesitating when accelerating then jumping into gear also while driving on highway truck felt like it was slipping out of gear and RPMs would jump up. Brought truck back to dealer again 3 months ago and they said torque converter was going bad and they would call me when part was in. two months later and they kept saying it was back ordered, now while driving going down steep incline into busy intersection felt like i got rear ended by another car, when looking back no car was close me truck stalled and started rolling into intersection I slammed on brake and got truck started again only to find transmission had failed and it slammed into gear when accelerating put my flashers on and got off road . Brought truck back to dealer to have them tell me transmission was now gone. truck has now been sitting on dealer lot for a month now with them telling me they can't get parts or transmission to fix. Very dangerous situation with this transmission and them knowingly kept sending me away in this truck. I feel that they knew about transmission problem over a year ago when I was bringing it in for the lunging forward after coming to complete stop at traffic light and kept saying nothing wrong. Truck was still under original warranty and only has 62k miles on truck.

SERVICE BRAKES
I purchased this vehicle brand new from Lunghamer Chevrolet in Pontiac, MI. I park my truck on a hill every day and as of around a week ago the emergency brake system won't disengage properly. I know it has been engaging since, my gas milage has decreased significantly. Then, a warning light came on the dash, so I took it to Wally Edgar Chevrolet in Lake Orion for diagnosis and they told me that the actuators and wiring harness need to be replaced. They said that there seems to be corrosion on the connector to the harness, and the actuators need to be replaced. Since, my warranty is expired they will not cover the repairs and they quoted me $2,125. I only have 48,428 miles on this vehicle! If the emergency brake is engaged, couldn't it completely stop my vehicle without warning? I drive the highway every day! Isn't this a safety concern? I don't go off road, I don't abuse this truck and I keep it clean as much as possible! Yes, I live in Michigan but, GM has been producing vehicles for quite a long time and I cannot believe they can't keep the wiring connector from corroding. I also went online to see if there were others that have experienced this, and I found one owner of the same model that had to fix it twice! [XXX] . I'm sure I could find more complaints but, I stopped there since I am so disappointed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FUEL/PROPULSION SYSTEM
While driving the engine jumps/jerks then goes back to normal, it continuously happens every 3-5 minutes while driving. A friend had his exact issue with exact make model year vehicle and it ended up being the gas sensor. Please look into this issue for this vehicle. Our local dealer will not fix it because the sensor doesn’t show the issue but that is the issue. The dealer knows it does it but won’t fix it.

The rear power sliding window in my 2020 Chevrolet Silverado 1500 LT leaks whenever it rains. The leaking water enters the cab and runs down the back interior wall of the crew cab and saturates the insulation material and the carpeting on the floor. The moisture has caused the seat brackets that attach the seat to the truck to rust and it has also caused mold inside the cab. I purchased a DIY mold test kit and it was positive for mold. My kids and I have allergies and this is causing issues with our health and if it continues it could cause serious health problems. This known issue of the leaking rear window is very widely discussed on many different gm truck forums and internet sites yet gm will not take ownership of this obvious problem.

Back window leaked. It was a heavy mist all night, not even heavy rain yet, and when we opened the passenger back door in the morning around 7:30 am, we found a pool of water on the back seat and water running down the seat. When I checked the forums, there is an abundance of complaints about the back windows leaking in Chevy trucks for many years now.

SUSPENSION
Today while driving , the upper ball joint separated from the control arm, causing the truck to pull hard to the right. I was able to keep from wrecking the truck. While doing research it seems that this is a common occurrence with the Silverado Trail Boss and the Sierra AT4. I read a safety recall report on these vehicles, 21V-718, after reading this, it's exactly what happened with my truck. Ball joints is rusting and corroded. Vehicle is able to be inspected upon request. If I had been on the freeway traveling, it would have caused a severe single or multiple car accident as I lost control to steer. No symptoms leading up to the situation.

SERVICE BRAKES
This problem concerns faulty emergency brakes. The issue was discovered in the driveway, when I engaged the parking brake with the vehicle in park and my foot on the brake. The Service Emergency Brake light came on and stayed on. When the problem was investigated at the dealership, it was found that the brake pad abradable material had delaminated from the brake shoe and was floating loose inside the drum. This same condition was found on 3 of the 4 brake shoes. Based on the appearance of the parts it did no appear they fell off when the parking brake was engaged, but had been loose for some time. With loose parts floating inside the brake drum sooner or later they will move and could lock up the rear wheel. The Chevrolet service department did not seem to be concerned with condition. A big concern is that the parking brake needs to be engaged to discover the issue. Many people rarely if ever engage their parking brake and could be driving around with loose parts in their wheels. The fact that this happened in just three years indicates the parts were produced with a faulty bond material. The abradable should never just fall off. On a backup safety system that is required on all vehicles, this issue should be taken more seriously by the manufacturer

SERVICE BRAKES, POWER TRAIN
Truck shudders, with varying degrees of vibration, emtek applying brakes. It is especially rough when applying brakes on the highway as it feels like it could lose steering control. Shaking is also very noticeable at slow speeds. Have had rear brakes serviced and problem persists. As of this month, the "service ESC (electronic stability control)" light has come on, along with other faults on the dash. VIN does not indicate unrepaired recalls, but this issue makes the drive feel dangerous
