2019 Lincoln Navigator Engine Problems

“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. …”

“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.”

“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. …”

“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.

“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. …”
