Is anyone out there familiar with the service bulletin for the potential engine knock ? Sometimes it can hear a low ticking kind of noise and I had read of a few people having issues with this. I am driving a 2018 Platinum with about 20,000 miles on it. The vehicle has lots of warranty on it but regardless, if there is an issue, I would like it to be resolved. Thanks in advance and stay safe out there !!

There is a lot of information on the Titan forums concerning this knock. I would encourage you check out:


Same engine made in same tenn. plant. Just shipped to Japan and used for our y62s.

Thanks very much for the direction. Just wondering , typically the dealership have a memo name or code for these issues or recalls. Any info on that ?

Also, when you say there is a short block and a long block, would that make any difference in regard to the engine power or output ? I believe our engines are rated at 385 hp.

Thanks for that. Is there a notice to address this put out to the dealerships or is it going to be a hit or miss thing with the dealership ? Of course meaning if they choose or not to do something for you.

There is a TSB

If you have a warranty
Nisssan or 3rd party
They will take care of it
They get paid, they will take care of it

A short block replacement is just the bottom end. Intake manifold, cylinder heads don’t get replaced. Unfortunately, there are Titan owners who have gone through the short block replacement, only for the problem to return accompanied by other issues due to the techs and their sloppy work.

That is reassuring ! Lol !

Well you have to wonder when you have any defective part replaced and the manufacturer hasn't made their supplier correct an issue, then they are putting another defective part in place of the other. So obviously it will only be a matter of time before that part gives you the same issue. I hate going to the dealerships anymore. As we speak, I have had the issue where you cannot get the shifter out of park and I have had all my idiot lights on for all the lane departure, front sonar etc. All kind of scary !!

For those following this concern, or if you have had the issue looked after. What may the repercussions be of not doing anything at all about this knock ??

Your engine will eventually completely fail prematurely, if this is not fixed. Cylinder 7 will be destroyed due to scoring.

I took mine in on Monday to have this very same engine knock fixed- the dealership looked at it about a month ago, said it wouldn't leave me stranded, but it did take them 4 weeks to get the parts in. Now they've said it will take all week to do the repairs. Just concerned about the long term ramifications....I guess I'll keep a close watch on it

I printed out the Service Bulletin and plan on taking to a different Nissan dealership here in our city. The first dealership took my vehicle for a 22 mile joyride and came back with a " normal noise " conclusion. What a shock. The service manager said they tried to chase down a noise on some other customer's vehicle and somehow it cost them money ( dealership) so he told me basically they would do nothing for me. Nice customer service !! Keep you posted ! Allan.

Typical of Nissan service centers who either act as if nothing is wrong, lacking the knowledge or experience in repairing what’s needed or being told from Nissan USA to avoid such repairs which isn’t surprising to me.
Besides a “test” drive, there are two additional and EASY steps these so called service centers can do to check for cylinder scoring. Pull out the coil pack(s) and plug(s) and use a borescope to inspect the area. A compression test would also be great in ruling out this knocking issue.

Print that out and bring it to your dealer. Show them how to do their job.

EDIT: and just realized you said you printed it out. Better luck with the 2nd dealer.

I stopped in at the " other " dealership for an issue with those nasty brake pedal switches. They where bringing up a BCI malfunction and had 4 idiot lights on for lane departure etc. The service guy there flagged down a mechanic to ask him about it and the mechanic asked if he could go out to my vehicle and look. So out we went and he adjusted the switch ( or switches ) for me. Hopefully that resolves that. So at this point, I gave him the paperwork showing the Service Bulletin on the engine knock. So we fired it up and he right away said that the knock was not present and what I was hearing ( slight ticking ) was the direct injection pump. He said he was aware of the Bulletin and that if you are going to hear that, it would be a deeper knocking noise for sure since it is in the block. So, I came away from that experience quite pleased with the actions at that dealership......and that's a good thing !! So fingers crossed and off we drive ! :)
