2017 Land Rover Discovery Sport

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.

I took my vehicle to a land rover dealership based upon 2 service bulletins issued by the manufacturer N768, sfcc_apr2022_17 and NHTSA item number 10211119. The Land Rover dealership refused to service the vehicle for those bulletins. I have a heart condition with 20% ejection factor. Since the telematics do not work in the event of a medical emergency my vehicle cannot be located for first responders. The dealer and manufacturer are not flashing or upgrading the telematics to modern standards which can be done easily by installing new software and/or changing out the telematics unit for 4G/5G compatible units and/or reprogrmming older units. As a result drivers with medical conditions are being put at risk if a medical emergency arises because the car cannot communicate to first responders as to its location to help an incapacitated driver.

Total loss of power steering. Was able to avoid crash but extremely dangerous. Has to get it towed to dealer $6,800 fix for total rack replacement due to bolts sheering off from EPS. Research shows this is a known issue due to faulty aluminum bolts in areas that salt roads.

BLOWER MOTOR stopped working. Due to the lack of forced air in the cabin, the windows and windshield fog up and it is impossible to see safely. Blower motor or blower motor resistor has failed providing no heat, no air conditioning, no air at all. Land Rover Service repair shop confirmed this is a $6,000+ repair due to needing to remove the dash completely (10 hours of labor). During rainy season, condensation builds in vehicle causing mold.

The seat belt buckle was damaged and would not latch or secure properly. It was not broken by use — it was already defective when the vehicle was delivered. I discovered the problem the day after purchase when attempting to use the seat belt. The buckle does not lock, meaning the seat belt cannot restrain the occupant, creating a serious safety risk. The dealer did not disclose this safety defect and rushed the signing process. The dealer has not responded to my attempts to contact them, and the vehicle title has not been submitted to the DMV, so I currently have no permanent plate. UNKNOWN as to the internal cause, but the defect clearly existed before delivery.

Incident

Sep 24, 2025

There was a loud sound coming from the driver’s side. I was told it was the wheel bearing & it sized to the axle & the entire hub/wheel bearing knuckle needed to be changed as well as the axle on the driver’s side. I was told it was dangerous to drive. Upon further inspection the mechanic told me the passenger side was seized to axle too so the same job will need to be done to the passenger side. Now they say I can drive the car but I’m worried about my safety & wonder why the wheel bearings are seizing the axles. This is a costly job. I’d prefer not to have to change the axle each time I need a new wheel bearing. I’m afraid to drive this car more than an hour from home or long distances.

The contact owns a 2017 Land Rover Discovery Sport. The contact stated that while the transmission was shifted to drive(D), the vehicle failed to respond immediately. Additionally, the vehicle lost motive power while driving. The check engine warning light was illuminated. The following messages were displayed: "Gear Box Fault", "Forward Collision Fault", "Hill Descent Fault", and several other unknown messages were displayed. The contact was able to restart the vehicle. The vehicle was taken to the dealer, where it was determined that the body harness needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 117,000.
