Toyota recalled more than a million units due to the familiar problem of rear-view camera malfunction.

The recall, which also involves Lexus units and Subaru models produced under the two carmakers’ ongoing collaboration, resulted from Toyota’s own software programming testing.

An interplay between the vehicles’ panoramic camera and parking-assist systems can lead to the rear-view camera image to freeze or go blank when the vehicle is in reverse. The Japanese automaker didn’t indicate in documents filed with the National Highway Traffic Safety Administration whether any crashes have resulted from the issue.

Toyota recalled certain 2022 to 2026 Toyota, Lexus and Subaru Solterra units that have the panoramic camera system. They are the: 

• 2022 to 2025 Lexus LX, NX and NX hybrid 

• 2023 Lexus NX plug-in hybrid

• 2023 and 2024 Toyota Prius Prime, RAV4 Prime and Venza hybrid

• 2023 to 2025 Lexus ES, LS and RX hybrids and the RZ; Subaru Solterra; and Toyota BZ4X, Highlander, Highlander hybrid, Mirai, Prius, RAV4 and RAV4 hybrid

• 2023 to 2026 Toyota Crown and Lexus RX

• 2024 and 2025 Lexus LC, LC hybrid and the GX, and Toyota Land Cruiser

• 2024 to 2026 Lexus RX and TX plug-in hybrids and TX hybrid, and Toyota Grand Highlander and Highlander hybrid

• 2025 Lexus LX hybrid and Toyota Crown Signia, Prius plug-in hybrid, RAV4 plug-in hybrid and Sienna hybrid

• 2025 and 2026 Toyota Camry hybrid

Toyota was preparing a software fix for the units and planned to mail safety notices to owners on Dec. 16, followed by recall notices once the remedy is ready for a software update by dealers.

Recall documents didn’t indicate if software problem is related to a recent recall of other Toyota models over faulty rear-view camera displays.
