Tuesday June 2, 2026 my car went into the shop. At which time the viscous coupler was replaced for the rear AWD differential. This was a Ford OEM Part that had failed. Upon replacing it shut up they found the rear differential gear assembly was in fact also in need of being replaced. The needed part is called a rear final drive. It is now June 30, 2026. My car has been in the shop now for 28 days. The rear final drive part needed is on backorder. “We are more than 100 on the list.” Therefore, I will not be getting my car back any time soon. Upon researching and discussions with dealerships, this is and has been a known problem with the Lincoln and Ford vehicles. However, there has never been a recall, or any justification for this known problem. I would like some answers to why anyone would have to wait that long for a part for their vehicle! I am without a car and will be for an extended period time!

I have had to replace my rear brake pads, rotors, and the whole braking system (not related to sensors) three times in a year. I received the recall notice after the third time and had a mechanic fix my brake hose as a short-term remedy for my car. Not only does my car have a delay in breaking it is a delay in the monitoring service. Technically the sounds related to my vehicle are not related to braking at all by the speed in which a car slows down before it breaks. In this case that mean if I slam on my breaks the "emergency sound" does not go off. I have a minor fender bender as well due to these two problems associated with my braking system.

The rear differential appears to be an issue on these vehicles. 2021-2022 models/vehicles were recalled for having an issue with the rear differential. Fortunately there was not an accident with my vehicle as I was able to determine that it shouldn’t be driven. However, I’m told by the dealership that there are 155 vehicles waiting for the same repair (a rear differential replacement), and that the part to repair it is unavailable. With this information, I can’t Imagine how many vehicles are still on the road with this problem. There does not appear to be a recall on older models, nor has this issue been reviewed by the mechanics that work for the company. At the very least, this issue should be reviewed during routine maintenance.

The contact owns a 2016 Lincoln MKX. The contact stated that on several occasions while driving at undisclosed speeds, the contact heard an abnormal sound coming from the hood of the vehicle. The contact stated that at start-up there was an abnormal sound coming the hood of the vehicle. The check engine warning light and the tire pressure warning light illuminated. The contact then stated that while driving at an undisclosed speed with the accelerator pedal depressed, the vehicle decelerated to approximately 25 MPH and went into LIMP Mode. The vehicle was taken to the dealer where it was diagnosed that the throttle body had failed and needed to be replaced. The vehicle was repaired; however, the failure recurred. The manufacturer was notified of the failure and the contact was provided a case number. No further assistance was provided. The failure mileage was approximately 134,000.

1EA21002 · Desiccated Air Bag Inflator Rupture
Opened Sep 17, 2021 · No close date supplied
Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
