Hey all,

New member here so I apologize if this was a topic before.  I tried looking but couldn’t find.  
 

I have a 22 RST With a 5.3 and have owned since 16 miles.  It now has 6,000 miles on it and makes a knocking or ticking sound while cold starting.  I took it to the dealer and they said that this was the direct injection working under a cold start.  Let me know your thoughts.  Video is below.  Thanks!

The video posted you cannot hear.  Not sure how I can get it on here.

Not DI noises.

 

Its either a lifter that isn't pumping up or has collapsed.  

 

Read this bulletin from GM 19-NA-218 - 19-NA-218 1..2 (nhtsa.gov)

Thanks for the reply.  Here is the video uploaded to YouTube.  Odd it does it only in the morning.  After sitting for ten hours at work it doesn’t do it.  Cold start is around 55 degrees to 60 degrees.  Any thoughts?

The service advisor who I was working with was going to show to his foreman on Monday.  Kind of unfortunate how it is pretty much brand new and will have to be torn apart. I am probably going to trade it in.

That sounds like  a lifter thats ready to come apart or not pumping up correctly.Thats not a normal noise and  needs to be addressed .We have engines torn apart all over the shop and parking lot waiting for parts that we can't get. Police cars sitting for months waiting for crankshafts or complete engines that GM can't produce fast enough to keep up with the failures. Lets not even talk about transmission problems.The 6.2 engines are seizing up before the first oil changes are due!  What has become of GM. I have been a line mechanic in a GM dealer since 1975 and never seen such a poor product being put out. I was with Oldsmobile when they came out with the 5.7 Diesel disaster and also Cadillac for 23 years when they crammed the HT4100 down everyones throats. They should be ashamed of themselves with what they are producing today and charging astronomical prices for. Don't let them tell you that noise is normal.

Thank you for the input.  I am in the transportation industry and I know that there is a problem.  I understand even I cannot duplicate customers concerns the first time around.  My argument with the service advisor really didn’t get anywhere so we’ll see where it goes when he shows the video to the shop foreman.  I’ll keep the thread updated with an outcome if I ever get one.

Refrence that bulletin I linked.  They can pull it up in GM Service Information.

 

Bulletin is 19-NA-218 and here is the link to read it for yourself - 19-NA-218 1..2 (nhtsa.gov)

 

"Technically" its 2019-2020 but the description of the condition sounds exactly like what you've got going on.

@newdude commented on a post I made that sounds similar to what you’re going through. Go check it out.

Mine does EXACTLY this. It’s the exact same in frequency and everything. Did you ever find out?

 

here’s the link.

Mine ended up being a scored cylinder wall. Engine replacement. Sounded just like yours.

    • Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
    • Paid $2.72 for E85 today.
    • Welcome back! No, it definitely doesn't pass the sniff test. Even "ceasefire" needs an alternative definition these days.    $5.29 at Kroger today
    • That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
