2023 Chevrolet Silverado 1500: engine knocking or ticking

Filed Sep 15, 2026 · Engine · OK

I have noticed a ticking noise that is coming from the engine, driver side, the tick after the recall was preformed, 5-23-2025. The tick has grown in loudness from that date. Took the truck to the dealership and they did a check but was unable to locate anything, no parts were removed and no witness marks on any of the engine areas Example oil pan and so on. I was told that they would charge me if the truck was brought back for the same issue per GM not the dealership. They have been doing my oil changes at a 3,000 mile interval. The tick has gotten progressively louder, and I am nervous about driving my truck but I can't not work.

On our way to [XXX], we heard a clacking noise coming from our engine. Pulled off the highway and had it towed to Reeder Chevrolet. It was Sunday XXX. On XXX we went to the dealer and they said we spun a connecting rod bearing and needed a new engine. Truck is a 2023 Slverado, 5,3 engine, with about 65000 miles on it. 5000 miles out of warranty. It took 18 days, and cost $12,214.37 to replace. Dealer stated that if I wanted to pursue a warranty claim, we would have tpo pay for them to disassemble the engine, diagnose the problem, then reassemble the engine, and they would send it to GM. GM would decide if it would be covered under warranty. If not, we would be out the cost of the diagnosis. I have always used 0W-20 full synthetic oil when an oil change was required. After searching this problem online, I found a tech service bulletin changing the requirement to 0W-40. We were never notified of the change, and the 2026 owners still say to use 0W-20. Attached are the invoice and recommendation to replace engine. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The engine in my 2023 Silverado ZR2 (6.2L L87 V8) failed. It is available for inspection at Rick Hendrick Chevrolet ([XXX]). On XXX at about 67,000 miles, and the days leading up to it, the truck repeatedly struggled to start due to metal on metal contact, almost leaving me and my family stranded multiple times. Driving the vehicle produced a loud rattling noise at 2200 to 2700 rpm, and felt unsafe to drive. Especially with my family. The problem was reproduced and confirmed to be an engine failure by the Rick Hendrick Chevy dealership a week after being dropped off with an appointment. I have been told the engine needs to be replaced under the special coverage program (N252494003). The L87 recall inspection and oil change was completed on XXX also by Rick Hendrick Chevy. There were not warning lights or other symptoms leading up to this engine failure. The symptoms of struggling to start and the ticking noise as 2200 to 2700 RPM started that weekend before I brought to dealership. They got progressively worse. Dealership has said I will receive a new engine under warranty but no timeline for completion. Additionally I have not been furnished with a service loaner or option for one. Leaving me with no vehicle to replace it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After the recall was done on my truck, it now makes a ticking noise that wasn't there before. When I bring this to the attention of the service department at the dealership where I purchased it, they say that noise is completely normal and sent me on my way.

My truck has the L87 motor on recall. i purchased it brand new and paid top dollar for it. I've had issues since I've bought it. All of my maintenance has always been done at the dealership from regular maintenance to purchasing brand new tires. I am very disappointed to have a truck that concerns to drive, i do not take my family out in my truck because i am not confident in its reliability and safety. multiple times i've taken my truck in for service and let them know to complete an oil change, tire rotation and to check an issue with a "tick, clunk and knock" just to be told it was "normal for the 6.2". my normal dealership has blocked off appointments online and you'd have to call to try to set one up. I demanded a diagnostic one time when the truck was acting weird and the tech stated "stop by, i'll squeeze you in" in which i did. however, i wasn't given any documentation since "i didn't have an appointment". After reviewing all of my service records, i come to notice not once time did they mention they did a diagnostic check. Only the recall test shows on one of the service records. I've had 3 different viscosity oils in my motor from the dealer stating GM recommended it. I had to night drop my truck on June 14 as it was making a weird noise from the engine and it felt like it had less power. I waited 2 days and the dealer did not contact to even state they have my truck in service. when i called to ask the status i had to agree to text message communication in which they replied, "at best it will take 2 weeks just to look at it". I asked for a loaner since i need a truck for work and transportation, they replied they do not have any and I will be placed on a list. My truck is still under original powertrain warranty and they cannot even provide a loaner. i feel that they are brushing me off to buy time and here i am making hefty car and insurance payments for a truck i do not have nor a truck that I NEED to provide for my family. GM does not care!

At approximately 24,000 miles the engine had catastrophic failure under normal street/highway driving conditions. The engine is the 6.2L V8. The issue began with a high pitch squeal or chirping sound and noticeable power loss. I parked the truck over night and then drove it to the dealer first thing the next morning. While on the way to the dealership, which was less than 20 miles away, the engine began having much bigger issues. A loud knocking noise was apparent and the rear end began locking up causing the tires to also lock up. Once at the dealership the engine completely failed and locked up. The engine did have the newly recommended 0W-40 oil installed prior to the failure.

I am reporting another engine failure on the 6.2L L87. This engine passed the initial recall testing and the oil was changed to 0W40 on September 30, 2025. However, my engine in my 2023 LT Trail Boss started knocking on Friday, March 20, 2026 (at 22,500 miles) after I picked up my children from school. Thankfully it started as I pulled into my driveway with them so they weren’t in any danger. No loss of power on the truck or warning lights visible. However, it was loud enough and odd enough for my [XXX] olds to even notice the sound in the cab. It was dropped off at the dealership on that Saturday morning and the GM dealership was finally able to look at it on Wednesday, March 25th and confirmed what was expected. The advisor stated the engine will need to be replaced due to the engine heading towards bearing/crankshaft failure. I am still currently without my truck as of today (April 4th) with no repair date in sight. I will say that the dealership service advisor has been very good about communicating about its status. However, he stated that he has had no luck finding an new engine and is unable to give a timetable in getting one. He did offer to start a PO for a rental car through enterprise. He stated they are not giving loaners, but could get a rental car. He also stated that it would not be a truck due to GM only giving $50 per day towards a rental. So here I sit currently without my truck. I see multiple reports about the engines being on back order and even the replacement engines are failing within the fist 500 miles. Some reports indicating they are on the third or fourth engine. Something needs to done about getting these trucks bought back by GM. They have clearly failed with this engine and are replacing the failed engines with the same thing! It is a well documented manufacturing flaw and design! I am thankful it occurred near my home. I would not have been happy with a catastrophic failure on a highway with my [XXX] old children in the truck!! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INF

The vehicle is currently exhibiting a loud, rhythmic metallic ticking/tapping noise from the top of the engine. This is a known precursor to a sudden, catastrophic loss of motive power as documented in GM Service Bulletins PIP5847A and PIP6101. The cause is attributed to manufacturing debris within the hydraulic valve lash adjusters, which prevents proper lubrication and causes valvetrain desynchronization. This defect leads to severe engine misfires (DTC P0300), "Reduced Engine Power" mode, and potential engine seizure. ​1. Component/System: The 2.7L L3B Engine Valvetrain / Hydraulic Lash Adjusters. The vehicle is available for inspection. ​2. Safety Risk: The audible ticking indicates imminent mechanical failure. This defect causes sudden and unexpected loss of motive power at highway speeds. Driving in this condition puts me at extreme risk of being stranded in active traffic or losing power while merging/passing, creating an immediate risk of high-speed rear-end collisions. GM is aware of this debris-related defect via TSBs but has not issued a safety recall to prevent the resulting power loss. ​3. Dealer Confirmation: Yes, confirmed by Chevrolet dealer on 3/18/26. The dealer knows about this particular issue, and decided not to act. ​4. Inspection History: Inspected by authorized Chevrolet service technician. ​5. Warning Symptoms: Loud metallic ticking/clacking that increases with engine RPM. This is a known precursor to a sudden, catastrophic loss of motive power as documented in GM Service Bulletins PIP5847A and PIP6101.

General Motors sent me a letter regarding a safety recall regarding my 6.2L V8 gas engine (ROP L87). Safety recall N252494000. I learned that my truck has the potential to have a complete engine failure. I took my truck to the dealership and all they did was an inspection and changed the oil on it. I'm not a mechanic, but total engine failure is concerning to say the least. I doubt simple change in oil thickness remedies serious recall. I learned there is an open lawsuit regarding this issue. I need Chevy to take this matter more serious, Im driving my family around in a ticking time bomb. I demand more than a band-aid. I want Chevy to replace my engine with a new reliable one.

I have an 2023 L87 engine that could stop functioning at any moment. I'm retired and bought this vehicle as my last truck. I don't feel safe driving it on long trips which is why I bought it. Also the transmission shifts rough from 1st to 2nd when I accelerate. When I inquired about the transmission problem at the dealership the showed me a letter sized notice saying this might be a problem. But I was not notified about this when I purchased the truck. I would prefer to just return the truck as I have it financed with GM Financial with no money down and am willing to just eat what I have already paid to get out of this ticking time bomb which I'm not comfortable driving long distance as [XXX]. Please advise. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving and idling, my 2023 Chevrolet Silverado 1500 High Country equipped with the 6.2L v8 engine began experiencing a persistent audible ticking/clicking noise from the engine bay, rough idle during cold starts, and noticeable/abnormal engine vibration. Shortly after, the check engine light came on. When scanned, diagnostic codes P0304 (Cylinder 4 Misfire Detected) and P050D (Cold start Rough Idle) were retrieved. The vehicle was inspected by an authorized Chevrolet dealership, and the service advisor and technician confirmed hearing a consistent clicking noise and documented that they contacted GM's Technical Assistance Center (TAC case #80413912). The service order report states: "Due to unknown noise cannot perform recall. Called TAC 80413912 and was told need to figure out top end noise and misfire before proceeding with recall. If repairs are related to top end, will not be covered under recall." The technician indicated this could be related to a camshaft and lifter issue, which matches the symptoms outlined in GM's active propulsion system recall for 6.2L engines. Suggests GM aware & has not yet confirmed full recall coverage/repairs. This issue presents a significant safety risk because the engine could experience sudden power loss or failure while driving, potentially leading to loss of propulsion or control. These symptoms are identical to those described by GM in their recall documentation concerning valve lifter and camshaft failures. The issue has been reproduced and confirmed by the dealership, and all documentation, diagnostics reports, and service notes are available for inspection upon request. Warning/check-engine lights first appeared in October 2025, and the problem persists. Based on GM's recall acknowledgment of similar failures, I believe this defect should be fully covered under the existing recall, and I am requesting the federal safety agency's review to ensure manufacturer addresses this safety-related defect promptly and without cost to owners.
