U3000 on Lincoln by model: symptoms, diagnosis and fix
On some 2024–2025 Nautilus SUVs, the Image Processing Module A (IPMA) can reset repeatedly, briefly or persistently knocking out the rearview camera image and driver-assist features including Pre-Collision Assist, Lane-Keeping Assist and blind-spot monitoring. Ford traced the resets to the module being overloaded when tracking many moving objects in dense traffic; warranty claims occurred mainly on vehicles used in livery service. The cluster may show "Front Camera Fault," "Pre-Collision Assist Not Available" or "Lane-Keeping System Off," and the blind-spot indicators may light. Recall 26V165 (Ford 26S21) covers 62,793 2024–2025 Lincoln Nautilus SUVs with the five-radar-sensor IPMA configuration, built September 4, 2022 to August 26, 2025. A Lincoln dealer confirms each VIN.
Common Symptoms
- rearview camera blank or frozen
- "Front Camera Fault" message
- "Pre-Collision Assist Not Available" message
- "Lane-Keeping System Off" message
- blind-spot indicators illuminated
How to Fix
Have a Lincoln dealer check the VIN for recall 26V165 (Ford 26S21); the IPMA software is updated free of charge by a dealer or over the air (2025 Nautilus owners notified April 13, 2026; 2024 Nautilus around June 22, 2026). Until repaired, do a manual mirror/over-the-shoulder check when reversing and treat BlueCruise/Lane Keep as unavailable — they can drop out without warning.
Call to confirm they can assess your vehicle and perform the stated work. Search results do not confirm qualification, eligibility or coverage.

Frequently asked questions
What does U3000 mean on a Lincoln?
U3000 stands for "Control Module." U3000 is a generic network code indicating a control module has detected an internal fault within itself or a related controller, or a problem in the module/CAN wiring system. It is often accompanied by a sub-fault letter or number that narrows down whether the issue is internal electronics, calibration, or a communication/voltage problem. In practice it means a module is reporting that it (or a module it monitors) is not functioning correctly, which can put the system into a protective/safe mode. On Lincoln it is documented across 1 model: Nautilus.
