Original coolant manifolds, two piece Vehicle was inspected by service tech at North Atlanta Land Rover in Alpharetta Ga on June 2, 2025. Vehicle was then inspected for a second opinion at Bear Valley Service LLC on June 10, 2025. Findings were consistent and I was advised to repair this two piece manifold system and its components before it failed causing catastrophic failure to the vehicle. Said repair was complete June 11, 2025. Safety to myself and potential passenger would be potential for vehicle to fail causing an accident, engine failure, steering issues, etc. This similar problem has been reported to Land Rover numerous times. Land Rover has not issued a recall although they acknowledge (per both techs) that this two piece manifold system is prone to splitting and cracking. Land Rover has sub sequentially changed and now installs one piece manifold systems to eliminate the prior problem. I had to pay for the replacement of this system regardless that Land Rover is completely aware this is a design or manufactured defect that was installed in my vehicle when it was built. I should not have to bear the financial burden to replace parts that the dealer and manufacturer have acknowledged cause catastrophic problems. The manifold issue was discovered by the dealership mentioned above and they recommended immediate replacement to avoid catastrophic failure. ($5116.30) i took the vehicle to another Range Rover authorized repair shop for a second opinion and they made the same recommendation. Based on that second opinion, I proceeded to have the two piece replaced by the one piece system to prevent catastrophic failure. I can provided the invoice listing labor and all associated replacement parts that were installed. This is a Land Rover issue and I believe they should pay the entire amount due to the fact they acknowledge the failure of these parts yet have no intention to do so.

While driving at approximately 20 mph, the front passenger control arm broke causing it to separate from the upper knuckle. This put my wife and other bystanders in harms way and could have caused an accident and or injuries. No warning signs or alarms. There is a Land Rover recall for this issue, but none are available for this model. This should be considered and included in the recall, since this a potential hazard and manufacturer defect.

I am the owner of a 2017 Land Rover Range Rover (VIN: [XXX] ). I recently discovered a crack in the front steering knuckle of my vehicle, which I believe poses a significant safety risk. This type of failure could result in a sudden loss of control, especially at higher speeds or during turns, potentially leading to a serious accident. I am aware that Land Rover issued a recall (NHTSA Campaign Number 24V-840) for a similar defect in the front suspension knuckle affecting 2014–2016 models, but my 2017 model is not currently included in this recall—even though the issue appears identical. Given the nature of the failure and its similarity to the existing recall, I am requesting that NHTSA investigate whether the recall should be expanded to include additional model years. I am concerned that other vehicles like mine may be at risk without the owners being aware of this potentially dangerous defect. Please investigate this matter for the safety of current and future drivers. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

EA26003 · Front Steering Knuckle Fractures
Opened Apr 24, 2026 · No close date supplied
Status: open (inferred from source dates) · Steering:linkages:knuckle:spindle:arm
The Office of Defects Investigation (ODI) is upgrading its Preliminary Evaluation (PE25006) of front steering knuckle fractures on model year (MY) 2014 through 2017 Range Rover Sport vehicles to an Engineering Analysis. ODI opened PE25006 on June 27, 2025, after receiving 12 Vehicle Owner's Questionnaire (VOQ) reports of the front aluminum steering knuckles fracturing in these vehicles. The reports describe the fractures occurring at the joint where the steering knuckle attaches to the upper control arm ball joint in one or both steering knuckles. Fracture of the front suspension knuckle can lead to detachment of the upper suspension arm. Detachment of the upper suspension arm results in the driver’s inability to control the vehicle, increasing the risk of a crash. ODI reviewed information supplied by Jaguar Land Rover (JLR) in response to Information Request letters as well as reviewed the data with JLR on numerous occasions. ODI further reviewed relevant data on a peer vehicle with a significantly similar steering knuckle design, the MY 2014 through 2017 Range Rover. Much of the information is contradictory and requires a deeper analysis that is available in an Engineering Analysis. On August 5, 2025, Jaguar Land Rover (JLR) filed safety recall 25V514. This recall covers certain MY 2014 and all MY 2015-2017 Range Rover and Range Rover Sport vehicles. The remedy for recall 25V514 addresses knuckles with and without a visible fracture. Knuckles that have developed a visible fracture will be replaced with a new knuckle of a substantially similar design. Knuckles with no fracture visibly present will have a brace attached to the upper portion of the front steering knuckle. JLR states that the purpose of the brace is to prevent the component from completely separating should a fracture develop. NHTSA continues to receive allegations of fractures occurring in the front steering knuckles of Range Rover and Range Rover Sport vehicles. Two of the most recent VOQs received by ODI involve front steering knuckle fractures occurring on MY 2020 and MY 2021 Range Rover L405 vehicles. ODI will continue to investigate the component design and assess the potential safety risk as part of this Engineering Analysis and evaluate the recall remedies for Recall 25V514. Further, the scope of this Engineering Analysis will be expanded to include MY 2018-2022 Range Rover and Range Rover Sport vehicles as they have a substantially similar component design.

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).

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.
