In December 2020, Toyota began an investigation into certain 2021 Toyota C-HR crossover SUVs after receiving field reports from the Japanese market alleging that when using the Traffic Movement Notification feature (a Japanese market feature not available in the U.S.), the vehicle radar sensor did not detect a vehicle driving in front of it. An inoperative radar sensor also meant that other features, such as Pre-Collision System (PCS), Dynamic Radar Cruise Control (DRCC), and Lane Tracing Assist (LTA) could be affected. In these cases, dealer technicians observed that the beam axis for the radar sensor was out of specification and adjusted it during the inspection. After completing the adjustment and initializing the radar sensor, the vehicles were able to detect the preceding vehicle.

According to the defect report, certain 2021 Toyota C-HR vehicles are equipped with a millimeter-wave sensor (radar sensor) and a camera to detect objects in front of it. These sensors also support certain driver assistance features, including the Pre-Collision System (PCS).

Under certain circumstances, the initialization of the radar sensor may not have been completed correctly, resulting in the PCS not being able to detect an object in front of it. As a result, the vehicle will not provide warnings or braking assist, and would not display a message or indicator to the driver that PCS is not functional. An inoperative PCS, without a PCS malfunction indicator to the driver, may increase the risk of a crash in certain driving situations.

As of January 2022, Toyota has not received any U.S. field reports or warranty claims related to this condition. Based on their investigation results, however, Toyota decided to conduct a voluntary safety recall campaign. Owners of the subject vehicles will be asked to take their vehicles to their Toyota dealer to have the radar sensor inspected and properly initialize if necessary. Toyota’s number for this recall is 22TA02 and the NHTSA campaign number is 22V-107.
