This TSB was release July 17, 2021 edit....I just realized it was released 2019
https://static.nhtsa.gov/odi/tsbs/2019/MC-10163715-9999.pdf

I have been monitoring an unusual clicking/tapping from my new-to-me 2019 SV 4x4 Crew over the past few months. I had it in for inspection of the issue and Nissan kept it for a week. I posted a couple of videos in a separate post a month or so ago. I got lots of response from members of the forum but no REAL solution from Nissan except that there was nothing found although they did witness, 1st hand, the noise/ tapping that I complained of. Since I have purchased this truck, I haven't driven it 1,500- 2,000 miles. Nissan service told me they had no TSBs and did not have a solution to the problem I am experiencing. They recommended that some "oil additive(s)" might help with the next oil change as well as several other possible options. They assured me, in writing, that there was nothing for me to worry about and that it "is not a mechanical problem" and that my truck is "safe to drive". I hope they weren't wrong

As I read the details of the TSB, it clearly says that Nissan should not allow the vehicle to be released to the customer if a "NG" (I assume No Go or Not Good) condition is foundand could need to replace the long block/engine if the defect is present.

I'll be calling and scheduling the inspection ASAP. Lets see where this goes.

There are only 186 Frontiers affected. They know the VINs of everything. If you had a problem engine there would have been red flags going off when they put the VIN into the service computer. In short, this TSB does not affect you.

PapaMike.....let us know what the results of your engine crankshaft inspection is on your motor. Did you purchased your 2019 truck fresh off the assembly line with 5-10 miles from the Nissan dealership or did you buy it used with 20K miles on it from a Nissan dealership?

The Technical Service Bulletin you referenced states it's the DEALER'S RESPONSIBILITY to check the 186 vehicles that were affected. It's possible that there may be more motors affected by the Technical Service Bulletin than Nissan is aware about, hence the reason Nissan Corporate requesting the inspections from the dealerships. Not all personnel at Nissan dealerships check the Service Comms or National Service History like they should be, and not all Nissan Frontiers are sold thru dealerships. Countless vehicles are bought by national rental car companies and are used in their rental car fleets so Nissan could be delivering vehicles directly to them. Covid caused a lot of rental car companies to dump fairly new cars and trucks because of massive losses suffered during the quarantine / economic slowdown.

Nothing wrong about PapaMike being cautious and requesting the Nissan dealership drop the oil pan to inspect the engine crankshaft. I would do the same also if I was hearing that rattling noise at cold startup. I'm definitely going to have a conversation with the Nissan Service Advisor about that TSB next time I take my 2019 truck in for it's next oil change. I'm not the original owner of my 2019 truck as I purchased mine used from a Toyotal dealership during the economic slowdown. I got such a great deal for me on the price, and the low miles on the odometer that I took my chances - Carfax and all....and I still have a year and about 14K miles left on my Nissan 3 year / 36 thousand mile warranty.

Better to be safe than sorry..... The worst that the Nissan dealership can do is 1). Say No to the Request for the Engine Crankshaft Inspection, or 2). Charge him for it.....

Thanks for noting this. I was wondering why that 186 was there. I googled the subject including the "186" and thought it could be something other that 186 out of 100,000 trucks produced out of a specific batch. How stupi of me. I guess that reduces the likelyhood of MY truck being affected. I hope you are right and that Nissan didn't let my truck slip through this TSB.I must admit. I thought I might have found a solution to my phantom cold start noise.

Is your dealer now using their standard dealership 0w20 oil in your truck?
I am not sure what they use/used in this truck for oil. I haven't had it long enough to see any service orders except the one from where I took it in for the cold start ratlling.

I will definitely share my results. I bought this truck used from a Nissan dealer near me with 34k on the clock as a certified pre-owned. It is in pristine condition and runs perfect. When I bought it, I didn't have the opportunity to get a cold start from it. I suspect it might have been used as a rental or fleet vehicle. I only noticed the rattle a few days after getting it home. To be on the safe side of the curve, I am going to request that they check it for this defect as the rattle has not been resolved. Thanks for your input.

I'll have my dealer check to see if my 2019 is one of the affected ones. Thx.

If it was used as a rental or loaner it’s on the vehicles service history/carfax.
I learned this when my daughter was considering a one year old grand Cherokee and my insurance company said it listed as that usage and will cost more to insure with an unknown life so I bought her a brand new one instead.
Good luck to you.

Is this the rattle that is only heard when 1st starting cold then goes away after a few seconds? If so then try a royal purple oil filter on your next oil change. It stopped my rattle I had at startup. They use a synthetic anti-drainback valve that seems to work really well. YMMV

You are correct. I spoke with Nissan today and they confirmed that my truck is not part of this TSB.

I'll try it when I get my next oil service.

So the UPDATE:

Nissan service told me that they ran my VIN number for the TSB and it did not apply to me but they remembered my issue from previous visits and MULTIPLE complaints. They informed me that my issue had been sent to some group of Nissan specialists/engineer/gurus and that my issue was being evaluated via my multiple video submissions to them. I am expecting a call from service within the next day or two with followup. I am still hopeful that the issue will be resolved.

So, they want the tech to remove the engine covers, drain the oil and drop the pan, get the crank pulley into position, inspect the crankshaft, (if okay) clean all of the RTV off, reseal the pan and install it, re-install all of the covers and refill the oil and check for leaks...all for 36-minutes of pay! Gotta love that warranty work!

Lol......they don't want mechanic's hanging around to long at nissan, they might start demanding decent pay or benefits. This must be the reason you meet so many mechanics who USED to work there.

When I got my new 2019, it was ticking on start-up. Changed out the factory oil with Amsoil 5-30 Signature Series and noise was gone. Since changed with Rotella 5-30 synthetic and have same quiet results. Don't know what oil they put in from the factory, but it is crap.

That's why I went from being a Nissan Master Tech to working as a correctional officer in a VA state prison! A/C, clean hands, benefits and a pension!

@PapaMike you have a solid paper trail, a key when warranty issues arise.

For peace of mind at next oil change I'd send a used oil sample to Blackstone Labs. Knowing levels of metals will give some peace of mind for $30. I would however save reciepts for you oil and filter purchased near the change day to keep in good graces with Nissan and your dealer on your issue.
