2014 Chevrolet Silverado 1500: engine knocking or ticking

Filed Jul 9, 2026 · Engine · SD

While driving, the vehicle suddenly developed a severe, loud mechanical ticking noise from the engine compartment, immediately followed by a drastic loss of engine power and violent vehicle shaking. The vehicle experienced an active cylinder misfire caused by a failure within the Active Fuel Management (AFM) system, where a cylinder deactivation lifter collapsed and became stuck.This mechanical failure creates an extreme safety hazard. The sudden drop in throttle response, engine stuttering, and loss of power impair my ability to maintain highway speeds, merge safely, or accelerate away from oncoming traffic. The engine stumbles significantly under load, risking a rear-end collision on public roads. The vehicle remains unrepaired at this time due to the catastrophic nature of the valvetrain defect and the severe risk of complete engine seizure while in motion. General Motors has failed to issue a safety recall for this known structural valvetrain defect, which poses an immediate hazard to drivers on the road.

While driving to work a month ago (3/19/25) I lost the power to accelerate out of nowhere. And my truck started making this noise, what I can only describe as a winding up noise while trying to accelerate. I was going 55mph on a busy morning commute. There were no warning lights. I pulled over and shut the truck off. Checked oil (even though it was changed a week or 2 prior). Oil was fine. Let truck sit for 10 mins then tried to turn back on, it started but had that winding up noise when just sitting in idle, the check engine light then came on after it was on for a minute or so. Ran codes at home, and truck started making an additional rattle noise on top of the winding up noise when had to be turned on. One code was the crankshaft position sensor, we changed that out. Then the truck wouldn't start. Taken to Dealership, and they said initially they found a broken connector to the engine harness. Fixed that then truck started but still making the rattle/clunk type noise and louder than at home so they continued diagnostics because they said the noise sounds like a rod knock, so rod either being bent/broken/slipping. Further diagnostics found that oil and coolant are mixed along with metal shavings through engine so new engine is needed.

Lifter failure happened while traveling home from Florida to SC. I was towing a vehicle and barely made it home. Having to drive at low speeds on the interstate put me at risk for accident. Now that I’m home I’m losing money because I have been unable to work due to not being able to drive the truck. The dealership quoted me $4700 to fix when there is a known class action lawsuit for this exact problem. GM should just replace these motors. This is very dangerous. There were no prior warning signs it just started ticking after stopping for fuel.

Code p06dd came on while driving home from work 10 miles away. We reset and truck was driving fine. On 10 degree day, truck displayed low oil pressure shut off vehicle while driving one mile away from work. Checked oil and topped off, tried to start vehicle, heard a noise and truck started ticking noise. Replaced spark plugs and oil pressure switch and still ticking. Forums stated it could be that or the oil pump. Looking at putting in a new oil pump but wondering if this is part of the previous recall.

Truck under 52,000 miles, had all known recalls (6) performed at cliff anschuetz. All maintenance performed within manufacture specified guide lines here also. Truck never displayed error code or service engine light since purchased new. Driving home from work 45 miles an hour march 6, 2019, engine message displayed with beep tone: oil pressure low turn off engine. I immediately pulled off, let truck sit for 5 minutes. No oil or fluids where leaking. Oil appeared normal and at proper level, did not smell burned. Started engine error code was gone, drove 1 miles to auto repair shop. Same error message appeared after going 100'. Auto repair shop gave me bad news 3 codes: 1) p0324 knock sensor, 2) p0521 engine oil pressure performance, 3) p06dd engine oil pressure control solenoid valve stuck off. Went to feldman chevrolet of highland, technician told me this should be covered under warranty, lakeside towing delivered my truck there. Feldman will not cover repairs stating out of warranty. Will give me $2000 dollars off on certi rebuilt motor, my cost $7,200 w/12 month warranty. Not acceptable. Salesman there offered me $8000 as trade in. Working with gm complaint department, they have been given all information. Been nice but seems like I am caught in middle between her and service manager at feldman. As of, 4/30/2019, I am awaiting a call back from gm. This is a known defect in this engine described in so many blogs! Google 2014 chevy silverado 1500 engine failure. Vacuum pump only warrantied to 36k, 2016-17 trucks only have a 60k powertrain warranty. Tells you something, gm dropped powertrain warranty down to 60k for 2016-17. This is not common problem, only a matter of when the vacuum pump fails. Pump fails, starts pumping metal debris back into oil/lubrication system taking out the oil pump then the engine. I owe feldman $970 for tear down and for removing oil pan!
