2024 Hybrid Nautilus (Engine Problems)

[angore]

The CSP notice does give the build date range - 7 Oct 23 to 28 Feb 24. I suspect the entire production of hybrids is affected and would require a list of 6000+ VINs. At my former employer, the sequence of the product was unique 1000, 1001. etc but the sequence was shared so say a hybrid could be 1001,1003, 1007, 15, etc., The sequence was not always 100% chronological in terms of build. It is easier to track build dates since tied to when parts at an engineering change level are used or a mfg process change.

If the Lincoln party line is keep driving, one may think the failure rate is fairly low between now and when parts are available. They will never say how many have failed (poor engine performance) vs total engine loss (most what is reported here) or how many they expect to fail. Even if it is just the injector, it will sit idle until new parts or will they put in existing parts and say keep driving.

Was the knocking related to uneven pavement or was it constant (rhythmic)?

Seemed certainly related to uneven pavement/wheel vibration. I only noticed it about halfway through the trip back, and I'm pretty sensitive to noise so I feel like I would have noticed it before, if present. The car also seems to need wheel balancing done, on seemingly smooth pavement there was still a rear and front vibration evident at 50MPH +, with the knocking sound beginning around 70MPH.

Phew! That’s great news, welcome home.

Eyes were fixated on where I could pull over quickly, sweating through construction zones with no shoulder.

Dice roller (foo3922). What was your build date? My vin sequence is 806322. I suspect that the last four digits are significant.

My build date is 11/23, vin sequence of 796496.

Our Canadian cousins weren't left out - they received their own 1 May letter. The Canada letter talks to end of May for the Dealer Bulletin, vs. end of June for the US letter.

And here's the updated 1 May US letter, now stating mid-May (instead of end of June) expected availability of the Dealer Bulletin, etc., courtesy of Haz.

@markfm has a good theory, but just to make a comment, the 12V battery is needed to operate the vehicle. It's used to power subsystems, including the computer.

Agreed. My comment was due to the "it did not solve the problem" by replacing the 12v (I'm reasonably confident they would have installed a good battery). The " 'find safe place to stop', and then shortly after the vehicle lost power and just stopped." sounds consistent with the description of 24B23 - main engine went bad, warning message generated, the car could only go a short way running off the hybrid system, then it's dead.

@jsp0919 - Any news? Was it something else (not a dead engine)?

Are the fuel injector failures only happening with the hybrid or also the standard engine? The Ford bulletin seemed to indicate it may be an issue on many models using the 2.0L engine. I've had mine for nearly 3 months now, approaching 3,000 miles, and have had no engine or battery issues.

CSP 24B23, the high pressure fuel injector item, is specific to the hybrids, consistent with "SSM 52490 2024 Nautilus - 2.0L EcoBoost-Hybrid - Direct Fuel Injector Replacement."

I've seen a different SSM, "SSM 52419 Various Vehicles - 1.5L/2.0L/2.3L - Misfire With Diagnostic Trouble Code (DTC) P0301, P0302, P0303, And/Or P0304 Stored In The PCM". which sounds like it could also happen on the non-hybrid engines, but it only talks about spark plugs, not the fuel injectors.

Glad I didn't go with the hybrid this time around. On a recent trip I got 600 miles range on a full tank and 33.3 mpg. More important, no entine failures or dead batteries.
I think about all those folks with the EVs who have to stop every few hours to recharge from 20% to 80% capacity when the charge rate slows down and the advice to not let batteries get too low of a charge. So only about 60% of the battery range seems to be available. Not for me. I can get 600 miles after a 5 minute pit stop and no searching for a working charger.

Try reaching out through Lincoln Concierge? Let them know: you have a must-do long trip; are uncomfortable based on knowing that the CSP 24B23 says dealers shouldn't be demoing/selling vehicles flagged for that issue; how significant the problem is if it arises; you are seeking a loaner proactively given they have an acknowledged problem and you cannot afford to be stranded with a blown engine if it fails while on the road.

Well I'm surprised.

My first attempt to get a loaner on Monday failed. "All of them are booked until June."

As advised above, I called the Concierge around noon Monday and got the same reply many of us have. "If it ain't already broke, I can't help you." She did, however, call my service manager and ask them if they could help me out in my special circumstances. He was too busy to join the 3-way call, but said he would call me back.

He never did.

I called this Tuesday morning and asked for the service manager to see what he could do. They'd only leave a message and he'd call me back.

Again, I didn't hear back.

But this afternoon, I did get a call from my 'service coordinator'. Not sure that's her title. She said I was her contact for anything I needed in terms of post-sale support. She didn't know my story, but I gave her a quick rundown. She said, "You're in luck, because I'm also the loaner coordinator." After a period of key-clicking and muttering, she said she'd get me a loaner tomorrow. "It'll be a gas model, I hope that's okay." I'm like sure, I won't be as worried about it's injectors. I guess many have been complaining about not getting a like-for-like loaner.

Anyway, it worked (although I'll know for sure when it happens). Thanks for the tips, everyone.

update on my Nautilus breakdown. Mine also has the injector issue. I was told by Lincoln they hope to have a response to the dealer end of May.

I’ve been putting 93 Octane in my tank since I got it, mostly because of this issue. I’m not mechanically inclined, but I figure better gas can’t hurt.

I have only used 93 in my hybrid since I received it. Knock on wood, no problems…yet.

Honestly I expect that won't do anything other than make the gas stations happy, given the engine is specifically designed to be able to run okay on 87 octane, but if it makes you feel better go for it.

Lemon law it

 

[angore]

The current CSP now says mid-May. I was supposed to get a call back from service manager based upon call with Lincoln (she talked to the same service advisor) but I will call today.

 

[angore]

I did not see anywhere that premium was even recommended for the hybrid engine.

 

[jsp0919]

Lemon law it

how does the lemon law work? Does it vary by state or is it federal? I have no idea how to initiate or what the rules are. Thanks for any information you can provide.

In NC, you have to go through the fix ordeal first. As I read the sales agreement, it needs to go through arbitration.

Covered by the Lemon Law?​

Your car may be covered by the Lemon Law if all of the following have happened:​

• The problem occurs in some part of the vehicle that is covered by the manufacturer’s warranty and you are within the warranty period. It does not need to be something that keeps you from being able to drive the car. For example, faulty air conditioning or peeling paint could be considered defects under the Lemon Law.
• You tell the manufacturer about the problem in writing and give them a reasonable period, but not more than 15 days, to fix it.
• The manufacturer makes “a reasonable number of attempts” to fix the vehicle. This means that the car has been repaired for the same problem four or more times, or that it has been out of service a cumulative total of 20 or more business days during a 12 month period of the warranty.
• The manufacturers’ efforts to fix the vehicle fail. Under the law, they must either replace your car or buy it back. You get to decide between a comparable new car and a refund.

Checked with my dealer. Hybrid. They are aware of the high pressure injector issue. My VIN falls into the list. Their guess is notification should be mailed soon, no timing. Meanwhile driving around with fingers crossed. At 125 miles so far.

You get the full advertised hp/torque ratings with 93. It will run fine on anything 87-93 but makes the most power with 93.

I have not technical data on the injector failure cause, but more power and increased RPM’s probably could be an accelerant to this potential issue.

Again, Lincoln has not said what is happening or the QA or parts handling issue(s) surrounding an undefined batch of injectors or the other potential issue with improper installation. Either way it sucks that we are all walking on eggshells until end if May, or June, when the release more info and resources.
