AIR BAGS, SERVICE BRAKES, POWER TRAIN
My safety system service warning comes on for about 30 seconds and then goes back off. This has happened about 4 times now. The transmission causes my truck to shake randomly. My pulley is going out and the local dealer said they wouldn't replace is under warranty(even though my warranty was still is effect) because they said it looked like someone sprayed tire cleaner under the hood(I bought it from the same dealership that I took it to for this service.) The brake seem to shake already when coming to a stop. They seem as if they are wearing prematurely.

While vehicle is in 4-wheel drive or 4 auto or 4 L. It makes a grinding whining noise! I have contacted the dealer Newberry motors of Newberry MI 49868. I asked them about a service bulletin I saw on the noises I am hearing, and I was told service bulletins are only assigned to a vin number and not groups of vehicles. which is a lie!!! SO THE GRINDING NOISE IS BAD WHEN IN 4 WHEEL DRIVE. PERIOD. DOES NOT MAKE THE NOISE WHILE IN 2 WHEEL DRIVE. THANKS FOR ANY HELP THAT CAN BE PROVIDED!

SERVICE BRAKES, ENGINE
ESC failed. The 2021 Chevy Silverado (39495 mi) began to shutter and a slight bouncing of the rear end. The ESC light came on the service ESC warning on the dashboard then the check engine light began to blink at the same time the parking brake light came on. The dash warning switched to have parking brake serviced. The truck as best as I could tell applied the parking brake several times for no reason while at highway speeds and traffic on all sides. All warnings stopped when Auto engine shut down at exit ramp light. Previously brought into dealership for “Service ECS” and “Service Power Steering Drive With Care”. I was told “ unable to replicate “ (23194 mi). Vehicle was returned to me. They did confirm the dash warning was stored in the computer. I do not believe any warning (blinkers) or brake lights came on to warn vehicles behind me of the rear brakes being applied by the ESC.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
JULY 2022 DPF filter was throwing check engine light. Took to dealer to get diagnosed, part was ordered and the DPF was replaced August 19th 2022. Started to get headaches in vehicle while driving it. OCT 9th ended up in hospital after driving vehicle and was diagnosed with CARBON MONOXIDE POISONING. Experienced symptoms of losing consciousness, worst headache I've ever had, nausea for 5 hours, loss of feeling in body and seizing of body. Took truck to dealer to get inspected twice and nothing was found to be wrong with it. NOV 10th Took truck on another road trip and was having similar symptoms as before however had more chest pain this time so went back to hospital. Took truck back to dealer to have inspected again and was told that it was fine. Nov 18th took truck on another road trip and within 20 mins of driving had another horrible headache. Pulled over and needed to get air and ended up driving truck 4 hours home with windows and sunroof open to avoid getting carbon monoxide poisoning again. I have been ill since August and that is due to diesel and carbon monoxide poisoning every single time I drive the vehicle which is daily. The truck has been now at the dealership for 70 days without any update or improvement in the case.

SERVICE BRAKES, STEERING, SUSPENSION
So I have been having issues with my truck losing oil. My dealership told me that Walmart made an issue with the oil filter causing it to leak oil out. After the dealership corrected the issue. I was on my way to the store this morning it was damp so I was having a lot of traction issues. Got to the gas station checked tires, no issue with them. Temperature is above freezing. Just thought maybe it’s in my head. Well I get about 2 miles from my house and low oil light comes on again. So this is an issue. It has happened 2 times to me. Had I not been cautious I could have slipped off the road or had a collision because the oil mixing with the water on the roadways. I will be reaching out to my dealership tomorrow to try and get them to correct this issue again. Seems there is a service bulletin on how to tighten the oil filter. Because of oil leaks.

ENGINE
On 12/26/22 my wife noticed a noise coming from the engine of the pick up truck. On 12/27/22 I started the truck and noticed a noise coming from the engine. I lifted the hood to try and locate where the noise was coming from but I could not see anything. There were no lights on the dash. I drove to work and parked it. 8 hours later I started the truck back up and the noise was still there. I began driving home and the truck made a spurted noise causing me to jerk the wheel nearly driving off the roadway. The truck is still making the noise. I contacted the Chevy dealer and they explained they would take a look into the issue. I’ve done some research and noticed that a bunch of 2020-2022 Silverado’s have been having lifter issues. I’ve also seen that the dealers are only replacing one side of the lifter banks and the others are failing 500-2000 miles after the repairs. I’ve also seen that people’s trucks have failed on highways and streets causing accidents and or traffic hazards. This is something Chevy needs to look into and fix to prevent any serious injury or death created by these issues. I don’t have photos but I do have a video of the noise that I could email if need be since I can not attach the video to this form.

Anytime the weather gets colder than 32degrees Fahrenheit the DEF system freezes, which even if the tank is full makes the truck go into limp mode until it thaws out. The engine light pops on and off with no codes associated with it. Now the breaks and break lines are freezing when it gets below freezing. These are just a few of the reoccurring problems we’ve experienced since buying the truck less than a year ago.
