Recall basis
NHTSA recall 26V389 / JLR D120 was announced on June 26, 2026 and covers 250,857 Land Rover vehicles from 2020-2026 model years. The recall covers certain Land Rover Range Rover, Discovery and Defender vehicles. The recall report states that the connector to the driver's airbag at the clockspring may experience fretting corrosion over time.
The described mechanism can increase resistance in the driver's airbag circuit and may affect airbag deployment. The recall report also states that JLR defined the recall population from warranty claims for airbag warning lamp illumination.

Fretting corrosion is not caused by weather alone. But humidity, wetness, chloride and thermal cycling can modify contact degradation risk, especially when micro-motion and connector resistance are already relevant.
Complaint-data result
Public NHTSA complaint files are not warranty databases. They should not be expected to reproduce the full internal population used by a manufacturer. Still, public complaint language can provide a useful analog signal for geographic screening.
Closest public match
Exact recall model-family complaints with wording close to the recalled airbag connector or clockspring fretting-corrosion mechanism. This group is intentionally narrow.
Same model families
Exact recall model-family complaints containing electrical, warning-lamp or safety-system language. These records support screening, but they are not direct evidence of the recalled mechanism.
Broader field signal
Other JLR airbag or SRS warning complaints used to understand geographic patterns around related warning signals. They are analog context, not recall-population reconstruction.
Screening signal
These categories help compare complaint geography with environmental exposure. They do not replace manufacturer warranty data, teardown analysis or connector-level failure investigation.
| Dataset | Scope | Count |
|---|---|---|
| Direct complaint candidates | Exact recall model families with airbag/clockspring/fretting-corrosion relevance in public complaint text. | 1 |
| Recall-adjacent complaints | Exact recall model families with electrical, warning-lamp or safety-system language that may be useful for screening. | 113 |
| Broader JLR analog complaints | Other JLR airbag/SRS warning complaints used as analog field signals, not as direct recall evidence. | 46 |
Direct complaint evidence in the public files is sparse. That is itself an important finding: the strongest failure population appears to be in warranty and field data referenced by the manufacturer, not in public consumer complaints.
Geographic signal from analog complaints
Broader JLR airbag and SRS warning complaints show a geographic pattern that can be compared with state-level environmental exposure. This does not prove causation; it helps define where deeper warranty-data review may be most valuable.
| State | Analog complaints | Exact-model adjacent | Climetry interpretation |
|---|---|---|---|
| Texas | 11 | 4 | High RH80/RH90 exposure around Houston; relevant humidity context for connector wetness screening. |
| California | 10 | 17 | Heterogeneous state signal: coastal humidity and chloride in some regions, thermal cycling inland. |
| Florida | 3 | 7 | Miami proxy shows high humidity and strong chloride proxy, making marine exposure a key review dimension. |
| Georgia | 5 | 0 | Atlanta proxy shows substantial RH80/RH90 exposure without strong marine chloride context. |
| New York | 2 | 8 | New York City proxy combines coastal influence with seasonal humidity and wetness relevance. |
| Virginia | 2 | 8 | Richmond proxy shows meaningful RH90 and near-dew-point exposure hours. |
Climetry 2025 exposure context
Climetry 2025 metrics provide representative point calculations for selected state proxy locations. The values below are not vehicle microclimate measurements. They are environmental context indicators for humidity, wetness and chloride screening.
| State | Proxy | Mean RH (%) | RH80 h | RH90 h | CE class |
|---|---|---|---|---|---|
| TX | Houston | 76.1 | 4366 | 2418 | CE-4 Severe humid exposure |
| CA | Los Angeles | 65.0 | 2476 | 427 | CE-2 Moderate exposure |
| GA | Atlanta | 68.1 | 3069 | 1454 | CE-3 Humid exposure |
| FL | Miami | 75.7 | 3385 | 437 | CE-5 Tropical marine exposure |
| NY | New York City | 67.7 | 2481 | 811 | CE-3 Coastal humid exposure |
| VA | Richmond | 67.6 | 3016 | 1617 | CE-3 Humid exposure |
Engineering interpretation
Fretting corrosion is a coupled mechanism. Contact micro-motion or vibration can remove protective films, while humidity, wetness, chloride and corrosion products can increase contact resistance. Climetry provides the environmental part of that picture.
Florida and coastal Texas are relevant climates for a fretting-corrosion hypothesis because high humidity, high absolute humidity, near-dew-point conditions and marine chloride exposure can reduce drying potential around connectors. California is more heterogeneous: coastal regions can add chloride and persistent humidity, while inland regions can add thermal cycling.
This case illustrates why environmental exposure intelligence matters in automotive reliability. Climetry turns state- or site-level climate into engineering variables such as RH80/RH90 hours, condensation-proxy hours, chloride exposure and ISO-derived corrosivity indicators.
Limitations
- Public NHTSA complaints are not warranty claims.
- Complaint locations are consumer-reported city and state fields, not verified failure locations.
- Climetry 2025 metrics are representative point calculations for selected city proxies.
- This is an environmental-risk case study, not a causal failure analysis and not a failure-probability model.
