2021 CHEVROLET SILVERADO 1500 Complaints

2021 Silverado 19,000 miles no indication of failure at a busy intersection about to go thru intersection and engines started knocking, multiple check engine lights on. Luckily got thru the intersection and to my place of residence which was very close by. Truck was towed to Chevy dealer. Dealer found 3 bent push rods, 3 bad valves. This engine had the lifters fail completely out of the blue. Oil changed at the dealer, meticulously maintained. Dealer only replaced the faulty bank of lifters due to mileage, seriously if it was under 16,000 they would replace all of them. This is unacceptable. This truck left me almost stranded in a busy intersection, lucky I knew well enough to keep going versus getting T-boned. I just think GM needs to do something about this. Now fast forward to 41K and I'm at the dealer same symptoms except this time my warranty is running up soon and being forced into an extended warranty. There are plenty of online claims, chat rooms, posts, etc to warrant this as a safety issue.

The engine failed while driving down the road at night in single digit temperatures. After further investigation, there is a connecting rod sticking out of the engine. I looked to see if there was a recall or anything. Sure enough there was. 2021-2024 Silverado 6.2 liter engines for crank shafts and connecting rod malfunction. I'm curious how my 2021 6.2 liter Silverado that has a connecting rod sticking out the side of the block is not part of this recall?

The contact owns a 2021 Chevrolet Silverado 1500. While the contact's husband was driving at an undisclosed speed, the vehicle started chugging and the engine seized. No warning lights were illuminated. The vehicle was towed to an independent mechanic, where it was diagnosed with engine failure. The contact was informed that a rod had detached and was sticking out of the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact referenced an unknown recall with a similar failure description; however, the VIN was not under recall. The manufacturer was made aware of the failure but provided no assistance. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 50,000.

A week or two before I took my truck into decorah Chevy isr because tailgate was going up and down all by itself while I was driving or parked without me by it. They said it was just the latch button . So they fixed it they said and still my blinker lights would just come on and then I hit a deer and my seatbelt did not latch and my airbags didn't deploy even though my app says they did. I'm wondering if all three are connected with electrical . Either way my air bags did not deploy and my truck has extensive damage and my seatbelt didn't lock ,

The truck has 61000 miles on it I got it in August there is engine knock which sounds like a bearing might’ve went and now the rod is loose in there. There is a large recall already regarding the same make and model of my truck for this exact issue.

I was in an accident my seatbelts did not lock and OnStar was called , it says my airbags were deployed I could smell a smell but nothing deployed
