High Voltage Coolant Heater Delamination
NHTSA Recall Query RQ24002 — open, opened 2024-02-08 and involving the LUCID AIR.
NHTSA investigation RQ24002 is a Recall Query opened on 2024-02-08 and currently open. The subject of record is LUCID AIR, which places this file inside the Office of Defects Investigation queue for LUCID. Latest activity on this investigation was logged on 2024-02-08 — NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
A Recall Query like RQ24002 evaluates whether a previously issued recall is actually fixing the problem. NHTSA opens an RQ when owners continue to report the original defect after the recall remedy is installed, or when completion rates fall short of the agency's expectations for that risk tier.
Investigators summarized the matter as follows: "On January 11 th , 2024, the Office of Defects Investigation (ODI) received Recall 24V-011 that identified a safety defect in the High Voltage Coolant Heater (HVCH) installed in certain Model Year (MY) 2022-2023 Lucid Ai..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time.
Investigation Summary
On January 11 th , 2024, the Office of Defects Investigation (ODI) received Recall 24V-011 that identified a safety defect in the High Voltage Coolant Heater (HVCH) installed in certain Model Year (MY) 2022-2023 Lucid Air vehicles manufactured prior to July 2022. The HVCH may experience an internal delamination failure, which poses a risk of the vehicle losing defrost capability. If the HVCH fails, coolant cannot be heated, and the windshield cannot be defrosted. Loss of adequate windshield defrost capability could lead to restricted driver field of vision and an increased risk of a crash. The remedy outlined in this recall is a software update that identifies any HVCH failure when it occurs, which then provides a notification on the glass cockpit panel about the lack of defrost capability and advises the owner to contact Lucid for an HVCH replacement. On July 27 th , 2023, Jaguar Land Rover North America, LLC filed Recall 23V-518 which affects Jaguar Land Rover vehicles equipped with the same HVCH as the Lucid Vehicles that were supplied by the same supplier (Webasto AG). Jaguar Land Rover North America, LLC’s remedy is to replace the HVCH in the affected vehicles. The Office of Defects Investigation is concerned that by only providing a notification to drivers that their windshield defroster is not working, Lucid puts the driver in a situation where they could experience the failure during the same drive cycle as they receive the notification. In this scenario, the driver is not aware they have a failed HVCH until they are operating the vehicle and need the defrost function prior to being able to have the vehicle serviced. ODI is opening this Recall Query (RQ) to further assess the adequacy and safety consequences of the remedy described in Lucid Recall 24V-011.
About This Investigation Type
A Recall Query (RQ) evaluates the effectiveness of a previously issued recall. NHTSA opens an RQ when consumer complaints suggest that a recall remedy may not be adequately addressing the safety issue, or when the recall completion rate appears insufficient.
