# Service campaign 24LC03

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

The Engine Control Computer software has a programing error which can cause the exhaust variable valve timing \(VVT\) locking pin to temporarily get stuck. When this happens, an engine malfunction indicator lamp \(MIL\) can appear on the dashboard as well as diagnostic trouble code \(DTC\), P05CE00 to be set.

## Other bulletins for the same vehicles and component

- [23LD04](/bulletins/11036119.md), 2026-08-12, Service bulletin: ELECTRICAL SYSTEM. TECHNICAL INSTRUCTIONS FOR 23LD04 GPS Antenna May Not Receive Power CERTAIN 2024 Model Year NX250, NX350, NX350H, and NX450H\+
- [23LD04](/bulletins/11036118.md), 2026-08-12, Service campaign: ELECTRICAL SYSTEM. The subject vehicles are equipped with a GPS antenna wire harness that will not allow the GPS to operate when the vehicle is off as intended. As a result, the vehicle location cannot be identified through stolen vehicle location services when the vehicle is off.
- [L\-SB\-0010\-26](/bulletins/11032485.md), 2026-05-08, Service bulletin: ENGINE. Some customers of 2023 – 2025 model year RX 350h, RX 500h, and 2024 – 2025 model year TX 500h vehicles may experience one or more of the following complaints when the low fuel level warning light illuminates: • The total amount of fuel dispensed during refueling is less than the customer expects when the fuel nozzle automatically clicks off, preventing the customer from being able to put as much fuel into the tank as expected. • The low fuel level warning light illuminates earlier than the customer expects. • The driving range is reduced compared to customers’ expectations, resulting in more frequent refueling than customers anticipate. The combination meter software logic has been updated to help meet customer expectations.
- [L\-SB\-0021\-25](/bulletins/11031155.md), 2026-04-08, Service bulletin: ENGINE. OBSOLETE NOTICE February 27, 2026: This bulletin is no longer applicable and is now obsolete.
- [L\-SB\-0021\-25](/bulletins/11029897.md), 2026-03-07, Service bulletin: ENGINE. OBSOLETE NOTICE February 27, 2026: This bulletin is no longer applicable and is now obsolete.
- [L\-SB\-0052\-25](/bulletins/11026321.md), 2025-12-05, Service bulletin: ENGINE. Some 2022 – 2025 model year NX 450h\+ and 2024 – 2025 RX 450h\+ vehicles may exhibit a MIL ON condition with Diagnostic Trouble Code \(DTC\) P019064 \(Fuel Rail Pressure Sensor “A” Signal Plausibility Failure\) present. The Engine Control Module \(ECM\) \(SAE term: Powertrain Control Module/PCM\) logic has been modified to address this condition.
- [25LD01](/bulletins/11026311.md), 2025-12-05, Service campaign: ELECTRICAL SYSTEM. The subject vehicles are equipped with a rear motor unit and an HV Floor Under Wire that provide high voltage to operate the motor. Mud, water, or road salt could potentially enter the HV Floor Under Wire connector housing and could cause corrosion over time. Excessive corrosion could cause AM Radio Static during certain driving cycles, or the vehicle may not start.
- [L\-TT\-0326\-23 Rev2](/bulletins/11022963.md), 2025-09-09, Service bulletin: ELECTRICAL SYSTEM. Some customers may experience operational difficulties with some telematics features which they cannot resolve on their own. These resources, in conjunction with the Repair Manual, are for dealership personnel to assist those customers with user issues, user errors, and compatibility issues with other vehicle systems and external applications encountered while operating telematics features.
- [L\-SB\-0030\-25](/bulletins/11021725.md), 2025-08-08, Service bulletin: ELECTRICAL SYSTEM. Some 2024 model year NX 350 vehicles equipped with a T24A\-FTS engine may exhibit a MIL ON condition with Diagnostic Trouble Code \(DTC\) P042000 \(Catalyst System Efficiency Below Threshold Bank 1\) present. The Engine Control Module \(ECM\) \(SAE term: Powertrain Control Module/PCM\) logic has been modified to reduce the possibility of this condition.
- [L\-SB\-0009\-24 Rev1](/bulletins/11020669.md), 2025-07-10, Service bulletin: ELECTRICAL SYSTEM. Some 2021 – 2024 model year ES 250 and 2022 – 2024 model year NX 250 vehicles with A25A\-FKS engines may have a MIL ON condition with one or more of the following Diagnostic Trouble Codes \(DTCs\) upon cold soak start up with engine coolant temperatures between 14°F – 41°F: •P030027 – Random/Multiple Cylinder Misfire Detected \(Emission\) Signal Rate of Change Above Threshold •P030000 – Random/Multiple Cylinder Misfire Detected •P030100 – Cylinder 1 Misfire Detected •P030200 – Cylinder 2 Misfire Detected •P030300 – Cylinder 3 Misfire Detected •P030400 – Cylinder 4 Misfire Detected
