The driver's side door latch assembly (Part Number LC5Z-54219A65-H) on my 2021 Lincoln Aviator with approximately 79,300 miles has begun intermittently failing to latch when the door is closed. This issue first started approximately three weeks ago. The driver's door often requires multiple attempts to close before the latch finally engages. When it does latch properly, a distinct loud click can be heard. Prior to that click, the door may appear closed but is not securely latched. This is a major safety concern because there is no reliable way to know whether the driver's door will remain closed while the vehicle is being operated. I am concerned that the door could unexpectedly open while driving, creating a serious risk of injury to the driver, passengers, and other motorists. I contacted my Lincoln dealership and was informed that the replacement door latch was on backorder. The dealership advised that there were approximately 80 other requests for the same part. This raises concerns that the issue may be more widespread than an isolated failure. The vehicle is scheduled for repair on November 6, 2026. I have been advised the repair will require the vehicle to remain at the dealership for more than one day. The vehicle was previously involved in a front-end collision; however, the damage was limited to the front bumper and related electronic components. There was no damage to the driver's door, door frame, latch assembly, or surrounding door structure. The current door latch failure developed long after the front-end repairs and appears unrelated to that accident. Because the driver's door latch is a critical safety component, I believe this condition warrants investigation. A door that does not consistently latch and remain secured during vehicle operation presents a significant safety hazard.

Defect investigations
Loss of Motive Power
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 âNanoâ 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 âNanoâ engines, coordinated with the federal safety agencyâs 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 âgrinding burnâ 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 supplierâs 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 âspike periodâ of May 2021 â 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 âSilchrome Liteâ to âSilchrome 1â. 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 Fordâs 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 the federal safety agencyâs 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 Fordâs 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 âNanoâ 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. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to

I have a Lincoln Aviator 2021 that has had at least 6 recalls. I love Lincoln’s but this is ridiculous. I have 3 open right now with no remedy available. The first notice came to me March 2026. I haul grandkids a lot, my vehicle needs the recalls fixed so my vehicle is safe. Can anything be done about this?
The Driver Seat Module (DSM) is known to develop software glitches across the 2020–2024 Aviator/Corsair/Explorer platform, causing the seat to not move to the correct programmed memory position . Lincoln’s fix (per Special Service Message 51406, issued for Corsair but describing the same shared module) is a dealer reprogram of the DSM software. However, this did nothing to improve the problem. •Symptoms include complete loss of seat adjustment where switches do nothing and the seat is stuck in place, memory functions failing to recall saved positions, intermittent operation with clicking noises but no movement, and the easy entry/exit function drifting out of correct position over time. Additionally, the drivers seat bladders and actuators engage without driver input and the seat controls on the touchscreen, increase and decrease bladder input and motor control beyond the selected settings. This often HAPPENS WHILE DRIVING.
I have been having issues with my breaks sticking when applied. To the point that it’s completely stopping my car and i need to use my foot to release the brake from behind. I have had the dealership look at this issue and they can’t seem to find the problem. They also broke my car and claimed they did not feel the sticking. I’ve had the dealership look at my vehicle twice for this issue. It is a safety risk with children in my vehicle. Also everyone i lock my vehicle. My alarm is going off saying someone is opening the door on my Lincoln app. Additionally, every time i start my car it says the passenger door is open, when it’s not. The sync Bluetooth constantly connects and disconnects or if i plug my phone i to the charger for CarPlay it does not work. This biggest problem is my brakes sticking. Like i said when i am braking gradually they are sticking to the floor and not releasing. Thai doesn’t always happen but it has happen a lot recently. I need this fixed!!!!!
