• Recall R/2021/037 [UK]: The exhaust gas recirculation cooler could leak over time
  Leaking glycol coolant could create in combination with soot and oil sediments in the egr module ignitable deposits.
  the egr cooler will be internally inspected with an endoscope and replaced if evidence of leaking is found.

• Recall R/2018/099 [UK]: Restricted fuel supply could cause engine to stall
  The sealing cap of the pressure-limiting valve in the fuel tank delivery module may be damaged. This concern could lead to a reduction in fuel transfer from the left side to the right side of the fuel tank. Therefore it is possible for the engine to stall even though the fuel gauge would show fuel present.
  recall the vehicles that are likely to be affected and check the fuel pressure of the delivery module and the distance of the cap on the pressure-limiting valve. Where necessary the delivery module will be replaced.

• Recall R/2018/220 [UK]: Pistons in rear brake calipers may not be coated to specifications
  The fault affects the brake system in particular the brake calipers on the rear axle. Because of a faulty coating hydrogen gas (approximately 10 ml) could be created in the coating of the piston of the brake caliper. This will be completely outgassed during the first 2 months after the production process causing longer brake pedal travel. Under certain circumstances the relevant brake pressure cannot be build up in the rear brake circuit. As a result the brake force of the system may be reduced by up to 30%. The driver may feel a soft brake pedal and a reduction of the brake performance. In certain cases the rear brake circuit could fail leading to increased risk of an accident.
  on the affected vehicles the brake system will be bled.

• Desiccated air bag inflator rupture investigation # EA21002

  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.
