2019 LINCOLN NAVIGATOR Engine Problems

Purchased a 2019 Lincoln navigator in 2024 used at a dealership in Orange Park Florida. The vehicle was taken to the same dealership for an oil change, which is a Volkswagen dealership. I started to hear a loud shaking noise after starting it up. I took it to O’Reilly‘s auto parts and had to put on a machine and I also took it to Paul, Clark Ford and Yulee Florida. I was told by both that it was the cam phaser. The vehicle was also leaking coolant, and now the engine has completely blown in the vehicle. It has been sitting at a Lincoln dealership for three weeks with a blown engine due to the cam phaser Echt that was never addressed or corrected by Ford. The vehicle is just sitting. It’s now a boat anchor.

About 5 weeks ago, our Navigator's transmission had a mild slip, like it was accidentally put in neutral. Since there was no visible warning sign, check engine light, or clear indicator of transmission issues, we thought it may just be a fluke. Within weeks, the transmission slipping escalated from mild to extreme, causing major safety concerns. When in drive, it would struggle to accelerate, get stuck in the wrong gear, then overcompensate, violently jerking into the correct gear 20+ seconds after it should have. A few times, we narrowly avoided getting rear-ended or rear-ending others. Lincoln service confirmed the 10-speed automatic transmission in the 2019 Navigator is problematic and will likely need a full rebuild, yet there is no transmission recall. They also stated their service department was backed up 4-5 weeks due to transmission repairs. Over the last 2 weeks, we've had a full vehicle diagnostic and repair. The mechanic replaced both leaky transmission coolant lines and completely rebuilt the transmission. He confirmed the check engine light never activated and diagnostic trouble codes never generated. That is an extreme safety problem. According to Lincoln, with leaks and transmission slipping, DTCs should be generated, and check engine lights should come on, but it didn't happen in either case. Please investigate both the transmission failures and the trouble code generation!

No warning light on dash. Issues engaging in gears. SUV failed to shift in gear and engine rev up And takes 2 to 10 seconds to catch again before engine engages. No accidents yet. Additionally, during cold start my SUB is making a rattling and ticking sound and the SUV would shake. There were no engine failure or warning lights that came on and the engine doesn’t sound like it’s running correctly.

The contact owns a 2019 Lincoln Navigator. The contact stated that while starting the vehicle, the vehicle made an abnormal rattling sound. The vehicle was taken to the dealer, where it was diagnosed that the cam phasers had failed and needed to be replaced. The dealer informed the contact that the VIN was not included in Ford Campaign Number: 21N03. The manufacturer was notified of the failure and confirmed that the VIN was not included. The manufacturer referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 83,000.

Upon a cold start my vehicle was making a rattling and ticking sound and the car would shake. There were no engine failure or warning lights that came on but the engine did not sound like it was running properly and clearly something was wrong. I took the vehicle in and was told that the Variable Cam Timing parts need to be replaced. In doing some research it appears that the VCT on the 2019 Navigator has a recall for the VCT but my VIN was not included on the recall for some reason.

My vehicle fits all criteria for CSP 21B10 and CSP 21N03. The vehicle has 75714 miles whereas 21N03 covers up to 79,999 on this vehicle. The cold start rattle is very bad and drivability due to cam phaser issues has caused the vehicle to be not drivable, at least not safely… this vehicle meets all criteria for the recall, and the issue (confirmed by dealer - at dealership now) is the cam phasers and this recall 21N03 is the repair and they are very surprised our VIN is not listed, citing all of these vehicles require cam phaser replacement to be operable. As this is a known issue with 2018-2020 navigators with the 3.5 this should be covered by the recall.

the engine rattles and knocks with cold start. in reviewing online, this is a very common problem. The dealership told me their service lot is full of navigators needing to have CAM? replaced. The internet confirms mechanics frustrated with spending their entire day replacing the same parts. This issue is listed on your site, but it is not a recalled item. I would suggest auditing how many of these repairs Lincoln is actually doing. I was initially told the repair cost should range between $1,000-$2,500, but after my vehicle waiting over a month in their service lot, they told me the repair cost would be $4,500. To have an issue this common on a car that cost over $100k, seems like they should take more ownership.

Cam phasers have started to fail. Vehicle has been meticulously maintained and well taken care of. Ford even did the recall with a reprogram to supposedly fix the issue back in 2022. We always change the oil between 5,000 and 6,000 miles.

Vehicle dies while in Drive. Message shows "AUTO STARTSTOP SHIFT TO P, THEN RESTART ENGINE". Dealer advised low battery voltage causing it, but vehicle starts without issue when shifting to P. Battery is only 2.5 years old.

The contact owns a 2019 Lincoln Navigator. The contact stated that while driving at various speeds, the vehicle would not properly accelerate while depressing the accelerator pedal. The RPM's would suddenly increase before the speed was drastically reduced. The vehicle was taken to the local dealer for service however, the failure persisted. No further information was available. The manufacturer was notified of the failure. The failure mileage was 31,000.

Mileage: 31,000

If the rear trunk gate is up and the vehicle is running the passenger compartment will fill with carbon monoxide very quickly. This usually will happen if loading luggage or items in the back of the vehicle while the engine runs. Certainly a risk if kids are left in the passenger compartment while the truck is being loaded when the engine is running.
