Since 2023 there has been an ongoing issue with my vehicle. When Im in public parking lots and I am accessing the trunk. I’ve witnessed my trunk literally shutting down or closing as Im accessing the trunk. Ive recorded this safety concern and Ive reported it to the dealership and manufacturer. The last time this serious issue occurred was last Friday, May 9, 2025. I was loading the trunk with my purchases as the trunk began closing. Whatever is causing this to occur. Ive noticed that the safety feature that signals the trunk to stop closing when it detects an object in the way becomes disabled. The trunk does not stop closing when Im underneath it. Ive witnessed my trunk sporadically closing at least four to five times on Friday. I was able to record one time that it closed as I said it kept happening sporadically. On the same day, I called the dealership and left a message with one of the contact people. As of today, May 13, 2025. I haven’t not gotten a response. This is a safety and security issue that needs to not only be addressed but resolved. And I am not getting help with either of the two.

Recall 24S55/24V635 was issued in October 2024, the issue with intake valves was discovered prior to October 2021. My car was manufactured in July 2021 within the time of inefficient intake valves. The problem continues to exist as there is no remedy. No remedy and no problem dealer won't look at the car, (even with a clicking noise) I don't drive it with concern my engine will quit in the middle of the road and I could be 500 miles from home. It actually has to stop dead in the middle of the road to be looked at. I can't trade it because it's under recall. It's a catch 22. Why can't these vehicles be taken in and tested to see if the intake valves will crack. Consumer safety should be all that is concerned with, not the bottom line. Shame on Ford/Lincoln for hesitation and NHTSA for allowing it.

I bought the 2021Lincoln Nautilus in Aug 2024 with only 54000miles. I was leaving the dealership and driving home with my suv & noticed that the suv was slightly trembling. Since then, I realized that my vehicle would tremble once I put gas in it, and this would happen at any gas station. Secondly, once I pump my gas, the truck does not cut on at first. I have to attempt cranking it two times before I can leave the premise. I’ve realized that my truck burns fuel quickly as well. Thirdly, my 2021 Lincoln Nautilus will hesitate and jerk when I accelerate leaving from traffic lights. This also happens when I leave my driveway in the mornings. Fourth, the display has frozen quite a few times, and it began the second week of me having my vehicle. Even if I cut the truck off, wait, then on, the display may not go off, or it would glitch and freeze before working properly; this also happens in the mist of me driving; this has happened since Sept 2024. Fourth, the connect to my radio will glitch horribly that it has connected and disconnected my phone approximately 8xs in a 30 min span/drive; this occurred the end of November. My check engine light came on in October, and I took it to Autozone immediately, especially since I had been having problems with the truck since I bought it. The results read “small leak in emission evaporative system.” I scheduled an appointment with my dealerships that is located in Savannah, TN. Although I have a powertrain warranty, they informed me that if it was related to internal problems, then warranty could be used, but I would have to pay for the diagnostic exam which was $250. Although I told them about the transmission possibly slicking, the small leak in the fuel tank, and my display blacking out before my appt, they informed me that they charged per complaint. Therefore, after 3 hrs of being there, they only could inform me that my purge valve wasn’t closing, and they would check the engine and put on the $611 valve at my next appt.

EA23002 · Loss Of Motive Power

Opened Sep 29, 2023 · Closed Oct 31, 2024

Status: closed (inferred from source dates) · Engine

On July 22, 2022, the Office of Defects Investigation (ODI) granted a Defect Petition (DP22001) and opened a Preliminary Evaluation (PE22007) to investigate allegations of loss of motive power in model year (MY) 2021 Ford Bronco vehicles equipped with 2.7L EcoBoost engines. Complainants were reporting sudden engine failure while driving resulting in a loss of motive power, often without the ability to restart. During PE22007, the cause of engine failure and loss of motive power in the subject vehicles was determined to be intake valve fracture, and the full scope of vehicles affected by the subject defect was identified as all MY 2021-2022 Ford and Lincoln models equipped with either the 2.7L or 3.0L EcoBoost engines, referred to as the “Nano” engine family.  If an intake valve fractures in the subject engines, it may drop into the cylinder and contact the piston, often resulting in catastrophic engine damage. On September 29, 2023, PE22007 was upgraded to an Engineering Analysis (EA23002) to further investigate the subject defect across the full scope of affected vehicles. During EA23002, ODI visited Ford facilities to review technical information related to intake valve fracture in “Nano” engines, coordinated with NHTSA’s Vehicle Research and Testing Center (VRTC), and analyzed updated field data relating the subject defect. Forensic analysis of fractured intake valves demonstrated that the defective components exhibited “grinding burn” or out of specification hardness in the area of the keeper grooves. The presence of grinding burn is evidence that during the groove grinding phase of production, the temperature of the valve became sufficiently high to alter the microstructure of the material and is indicative that the valve supplier’s manufacturing processes were not within control specifications. Grinding burn results in a hard, brittle microstructure and high residual stresses toward the surface of the valve. Through normal engine loading, a valve with grinding burn will likely fracture at the area of highest vulnerability, which is the third keeper groove. In its response to the EA23002 Information Request (IR) letter, Ford provided evidence of 396 customer complaints (including field reports), 825 warranty claims, and 936 engine exchanges. When considering both ODI and manufacturer failure report data, there have been reports representing 1066 unique vehicles within the subject vehicle population. Analysis of the failure report data demonstrates that vehicles equipped with potentially defective intake valves were built within a production “spike period” of May 2021 – October 2021. The beginning of the spike period corresponds to a ramp up in production at the valve supplier manufacturing facility, and the end of the spike period aligns with the implementation of several mid-production process improvements and the decision to change the metal alloy used to produce intake valves from “Silchrome Lite” to “Silchrome 1”. Ford began investigating the subject defect in July 2021, determined the root cause, and took corrective measures for the new production vehicles. Analysis of the failure report data demonstrates that these corrective actions were successful in eliminating the risk of intake valve fracture for subject vehicles produced after October 2021. However, Ford did not take any field action to address vehicles produced during the spike period, and in the several months following the implementation of the production changes, a significant number of field failures continued to occur. It is Ford’s assessment that not all valves produced during the spike period are defective, and that failures associated with the subject defect occur at low time in service. Analysis of the failure report data demonstrates that the vast majority of failures have occurred before 20,000 miles with over half of all reported failures occurring before 5,000 miles. The rate of reported failures related to the subject defect has steadily decreased since November 2021. ODI coordinated with NHTSA’s National Center for Statistics and Analysis (NCSA) to conduct statistical analysis and predict the number of future failures associated with the subject defect. The results of this analysis, and the trends identified through the failure report data are generally consistent with Ford’s assessment that defective intake valves will likely fail at a low time in service and indicate that the majority of subject vehicles equipped with defective valves have already experienced a failure. On August 23, 2024, Ford submitted recall 24V635 for subject vehicles equipped with “Nano” engines and built within the production spike period identified above (total population 90,736 vehicles). The remedy includes an inspection at a Ford/Lincoln dealership where the lifetime engine cycles of the vehicle will be determined. If a vehicle does not meet a threshold for lifetime engine cycles, the dealership will conduct a high RPM engine cycle accumulation procedure, which aims to identify if the vehicle is equipped with defective intake valves. Any vehicle that fails the accumulation procedure will receive an engine replacement under the recall. In addition to recall 24V635, Ford has stated that it will launch customer satisfaction campaign 24N12, which will provide extended warranty coverage to the subject vehicles through the earlier of 10 years or 150,000 miles. In view of the recall action being taken by Ford, ODI is closing this Engineering Analysis.
