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.

2016 LINCOLN MKX - FWD- LOSES BALANCE WHEN ACCELERATED. ITS WOBBLES/ SWIRLS WHEN STEPPED ON THE GAS ON A CITY STREET OR ON A HIGHWAY. WHEN WE BROUGHT THE CAR IN, LINCOLN DEALERSHIP SERVICES FOREMAN, ADVISER AND DIRECTOR CLAIMED ITS THEIR MKX FWD NORMAL CHARACTERISTICS. THE DEALERSHIP DID NOT DISCLOSE THIS DEFECTIVE DESIGN AT THE TIME OF PURCHASING. THERE ARE NO FIXES, AND THE MKX AWD DOES NOT HAVE THIS PROBLEM/CHARACTERISTICS. WE HAVE CONTACT THE CORPORATE OFFICE AND THE MANAGER SAID THEY TRUSTED THEIR SERVICES ENGINEERS THAT ITS THE NORMAL CHARACTERISTICS OF THE MKX AWD. BOTH THE ADVISER AND THE CORPORATE MANAGER SAID FOR US TO REPORT TO OUR INSURANCE COMPANY IF WE GOT INTO AN ACCIDENT BECAUSE OF THIS DEFECTIVE DESIGN. WE BOUGHT A VERY EXPENSIVE CAR, BUT UNABLE TO USE ITS ABILITIES, BECAUSE IT IS UNSAFE TO ACCELERATE. WHO WOULD BUY A VERY EXPENSIVE CAR AND AFRAID TO STEP ON THE GAS? LINCOLN NEEDS TO DISCLOSE THE MKX FWD- DEFECTIVE DESIGNS THAT THEY CLAIMED TO BE THE NORMAL CHARACTERISTICS TO THEIR CUSTOMERS AT THE TIME OF BUYING. OR THEY NEED TO STOP PUTTING THE ECO BOOST ENG ON THE FWD MKX CARS.

VEHICLE PURCHASED FEBRUARY 2016. ON MARCH 15, 2016 (1,065 MILES), DRIVING VEHICLE APPROACHING AN INTERSECTION ON A BUSY STREET TO MAKE A LEFT TURN ONTO A MAJOR HIGHWAY ON-RAMP, VEHICLE LOST POWER WHILE IN MOTION AND APPEARED TO ENTER "ACCESSORY MODE". WAS ABLE TO BRING VEHICLE TO STOP (IN THE MIDDLE OF THE INTERSECTION), PUT IT IN PARK AND RESTART THE VEHICLE. BROUGHT IT IMMEDIATELY TO LINCOLN SERVICE DEPARTMENT. SERVICE DEPARTMENT HAD VEHICLE FOR TWO DAYS AND COULD NOT DIAGNOSE OR REPLICATE THE PROBLEM. GAVE THE VEHICLE BACK TO ME WITHOUT ATTEMPTING ANY REPAIRS. ON MAY 14, 2016 (2,838 MILES), DRIVING AT LOW SPEED ON BACK ROADS, VEHICLE LOST POWER AGAIN WHILE IN MOTION AND ENTERED ACCESSORY MODE. BROUGHT IT IMMEDIATELY TO LINCOLN SERVICE DEPARTMENT. THE SERVICE DEPARTMENT COULD NOT REPLICATE THE ISSUE, BUT FOUND A TSB THAT THEY THOUGHT WOULD APPLY TO THE ISSUE. THE TECHNICIANS REPROGRAMMED THE SOFTWARE IN THE POWER CONTROL MODULE AND GAVE THE VEHICLE BACK TO ME. ON JUNE 25, 2016 (3,663 MILES), DRIVING AT LOW SPEED ON A MAIN ROAD, VEHICLE LOST POWER AGAIN WHILE IN MOTION AND ENTERED ACCESSORY MODE. BROUGHT IT IMMEDIATELY TO LINCOLN SERVICE DEPARTMENT. THE SERVICE DEPARTMENT KEPT THE VEHICLE FOR TWO WEEKS TO ATTEMPT TO REPLICATE THE PROBLEM. AFTER SPEAKING WITH LINCOLN CORPORATE ENGINEERS, THE TECHNICIANS REPLACED THE THROTTLE BODY, ASSUMING THAT WAS WHERE THE ISSUE WAS ORIGINATING. LINCOLN REFUSED TO REPLACE THE VEHICLE AND INSISTED THAT THE THROTTLE BODY WAS AT THE BOTTOM OF THE ISSUE. AS OF OCTOBER 28, 2016, THE VEHICLE HAS NOT LOST POWER AGAIN. *TR

WAS ABLE RESTART IT AND MAKE BACK HOME, ON THE NEXT DAY10/09/16 I HAD THE SAME PROBLEM THIS TIME I COULD NOT GET IT TO ACCELERATE I HAD THE CAR TOWED TO THE DEALERSHIP IT WAS SUNDAY THE DEALER WAS CLOSED. I CALLED THE DEALER ON MONDAY AND TOLD HIM WHAT HAPPEN AND HE SAID THEY WERE WORKING ON IT. THEY CALLED LATER AND SAID IT WAS THROTTLE CONTROL AND A COUPLE OF ERROR CODES THAT REQUIRED UP DATING P2111, U0415 AND U0416. THEY ALSO REPLACED THE THROTTLE BODY. THEY ALSO NOTED THEY DROVE IT 9 MILES AND NOTED THAT ALL OK AT THIS TIME. THAT LAST COMMENT SOUNDS THAT THIS COULD HAPPEN AGAIN. THIS IS A VERY DANGEROUS PROBLEM HAD I BEEN ON THE INTERSTATE AT RUSH HOUR I MIGHT NOT BE WRITING THIS TO COMPLAIN. WHEN THIS HAPPENS THE CAR SLOWS ON SO FAST THAT THE CAR BEHIND DOESN'T KNOW YOU HAVE A PROBLEM BECAUSE YOU ARE NOT BRAKING WHICH MEANS YOUR BRAKE LIGHTS ARE NOT ON AND HE MORE THAN LIKELY IS GOING TO HIT YOU. THE FIRST TIME THIS HAPPENS IS QUIET SCARY BECAUSE YOU HAVE NO IDEA WHAT IS HAPPENING.

EA21002 · 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.
