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 contact owns a 2016 Lincoln MKX. The contact stated that while driving at 45 MPH and depressing the brake pedal, the brake assist, brake, traction control, and anti-skid warning lights illuminated. The auto-braking system became inoperable. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was not diagnosed or repaired. The vehicle was taken to an independent mechanic, who replaced the wheel hub, wheel sensor, lower control arm, and ball joint. Additionally, the mechanic informed the contact about several low voltage codes. The battery, alternator, and starter were working as designed, but there was low voltage. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The failure mileage was approximately 100,000.

I placed my foot on the Brake to release the Emergency brake. I heard a pop. The brake pedal immediately went to car floor. I didn’t know what it was initially but quickly realized something was wrong with my brakes when I was on the highway. When I tried to brake the pedal went to the floor and the car did not slow properly. I made it to the subdivision entrance when the low brake fluid indicator light came on. I made it home safely. When I stopped, smelled an odor (I was told it was likely brake fluid). I had it towed to the dealership. It was diagnosed the day after, informing me brake line had broke. I asked what was the cause and possibly wear and tear? He informed a weak spot in the line. I called Lincoln customer relations bc it’s a safety issue whether it is a new or old car under warranty to address my concerns. They explained I would have to pay since a warranty was not in place. As a customer, my car is under 100, 000 miles and I service it routinely. I am more concerned of this being an issue with safety than a warranty being in place. My son or myself could have been in a bad accident sustaining serious injuries with no brakes. The Lincoln rep implied my car was old, which is an insult. It’s only 7 years old. My 22 year old Toyota is still working and the brake line has never broke. I was informed by the service tech it is unusual to see this occur in the back brakes. The brake line/hose broke and the brake fluid leaked out. In my opinion, it’s a defect, durability, and a safety issue regardless of the age of my car. It is a much bigger problem that should be addressed. The customer service rep and her manager were eluding to their extended warranty program and they could not offer financial assistance. I have paid more for services when I feel it’s wear and tear. It is a safety issue with a possible defective part, which I should not be responsible to pay, regardless of a warranty being in place or not. Safety and durability are the bigger issue.

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.
