2022 Chevrolet Silverado engine problems

“I own a 2022 Chevrolet Silverado 1500 High Country with the 6.2L V8 (L87), covered by Recall 25V-274. I believe the remedy does not establish that my vehicle is safe, and GM has declined to confirm that it is. My truck was inspected under the recall in August 2025. It passed, and the oil was changed to 0W-40. I later returned to the dealer to complete the recall work, where the new oil fill cap was installed. Before the remedy, the truck had been driven roughly 30,000 miles on the original oil, including repeated towing during a move. NHTSA’s EA26005 states it has received complaints of engine failure after both the oil change remedy and engine replacement, and that GM reported thousands of complaints of post-remedy engine failure. My vehicle received the same remedy. I asked GM in writing to confirm my engine does not have the defect and will not fail or lose propulsion because of it, or to explain whether the inspection can determine the condition of internal engine components. GM did not answer those questions. Its reply stated only that the remedy was performed “to help affected vehicles avoid the defect condition,” that the new oil “offers increased…”

“As I was driving, the vehicle threw a CEL and I saw the RPM’s fall. This happened multiple times, twice at an all-way stop sign, and once at a major intersection resulting in me being stranded with my vehicle in the middle of an active roadway, unable to move my vehicle. I brought my vehicle into the Chevrolet Dealership and the service department is claiming that I need to pay $1500 for a fuel pump with a CEL code that is not able to be duplicated. There is a TSB 24-NA-139 regarding my issue saying that it is not the fuel pump, it is the fuel pump control module. My issue is that the dealership wants me to pay $1500 for a fuel pump solely off of their “guess” of what the issue is. The bulletin calls out the P102B as one possible code related to the issues. I refused this service since this is just the dealership’s guess of what the issue may be and I believe the fuel pump control module should be replaced for free under the 8yr/80k federal emissions warranty. I requested that the dealership check the module as a part of the $245 diagnosis I paid for and they are insisting that the issue is with the fuel pump.”

“I have a 2022 Chevrolet Z71 with a 6.2 l L87 engine. The motor blew up for what the recall is for from chevrolet.The crank and all that stuff seized up while my step son was driving it was told to burn Chevalier of rock. Hill, where they said, yep, this is the exact recall problem that we've been having with all these trucks. And the truck still isn't running, right?It's still knocking and making weird sounds and losing power after getting a new motor”

“I am reporting an engine failure on my 2022 Chevrolet Silverado equipped with the 6.2L V8 engine, following completion of NHTSA Safety Recall 25V-274 (GM N252494000). The recall was performed when my vehicle already had over 150,000 miles. At that time, GM performed the oil-and-cap remedy rather than replacing the engine. Approximately 9,000 miles after the recall repair, at approximately 193,000 miles, the engine began making knocking noises and subsequently required replacement. There was no low-oil warning that we observed before the failure ( both in the vehicle nor on the app) and we were not aware of any oil leaks. The vehicle had also been serviced by our local mechanic approximately 3,000 miles before the failure, at which time the mechanic advised that an oil change was not necessary. I am concerned that this failure may be related to the connecting-rod or crankshaft defects identified in the original GM recall and that the recall remedy may not have adequately corrected the problem. I am requesting that NHTSA review this complaint as a possible engine failure following completion of Recall 25V-274 and consider it in its investigation of post-recall…”

“I have the 6.2l motor and this motor is failing AGAIN. They did the pick test and I did not qualify for the recall. But my truck is making the same noise again before it blew. The Chevy dealership informed me that it was the valve train that was causing the motor to blow. But this is the second motor. How can the second motor have the same problem right? Well this motor is now about to blow and again the dealer said it’s the valve train. The noise is coming from the lifters and the variable valve train and the mechanics of the valve train are what is causing the to blow. This is a main reason why the motors are blowing even after the new oil was changed. I don’t know what’s to do with this truck because it is out of warranty and it is about to fail”

“The contact owns a 2022 Chevrolet Silverado 1500. The contact stated that the vehicle was consuming an excessive amount of engine oil, Additionally, the vehicle rattled abnormally and lost motive power intermittently while driving 70-75 MPH on the interstate and while driving uphill. The driver pulled over to the side of the road on several occasions; however, the vehicle stopped in the middle of the road on one occasion while driving uphill. After waiting for several seconds, the vehicle became drivable. The contact stated that the engine was previously replaced twice due to similar failures, after which the vehicle needed to be towed. The manufacturer was notified of the failure and referred the contact to the dealer, where an oil consumption test was recommended. However, the contact stated that the oil consumption test required driving the vehicle. The contact associated the failure with NHTSA Action Number: EA26005 (Engine). The failure mileage was approximately 7,000.”
