2021 CHEVROLET SILVERADO 1500 Complaints

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.

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.

Vehicle will not start and cranks until starter kicks out, about 30 seconds each time. I am afraid if this happens at a traffic signal or stop sign it could be bad. I took it to the dealer on July 30-2022. (2972 mileage) and they could not verify concern. I found a safety bulletin on a GM website for a extended crank/ no start. It is PIP5806D, The dealer says they know nothing about this. It lists a labor operation number 4088148, due to a corrupt signal from camshaft position sensor to the ECM. It has happened now 4 times, and current mileage is 6973. I have been dealing with Champion Chevrolet in Reno NV. It has started after 8 to 10 crank time outs and the battery starts slowing the crank speed down, but around 10 to 15 minutes have passed by then.

Engine oil cooler defect was diagnosed by chevrolet dealership. Everytime I drive the truck, it would leak oil and would have a burning smell all underneath the truck. The part was on backorder for over a month and a half. After this long wait of not being able to drive the truck, the dealership finally put a new oil cooler in. The problem persists and they are not able to figure out from the engineer what will solve the problem. I have been out of a truck for over a month and a half now with no hopes of the issue being resolved.

Power hesitation, along with loud knocking sounds coming from the engine. Cause truck to completely shut off while driving 35mph. No warning lights or anything came on until complete failure

Per the repairing dealership, a lifter went bad. GM will not replace all of the lifters, just one side of the engine, due to the vehicle having over 8000 miles. Mine currently has 12,500. I no longer feel safe knowing that GM is replacing only half of the know defect with new parts that have the same issue (Told to me by the repair facility.) The vehicles engine could fail again, resulting in loss of acceleration. No warning was observed during, however after the fact, check engine and other warning lights were illuminated.
