Forward collision avoidance: automatic emergency braking; electrical system:adas:driver monitoring:camera/sensor; lane departure: lane keep: automatic steering
Problem: Tesla, Inc. (Tesla) is recalling certain 2020-2021 Model 3 and 2021 Model Y vehicles. The fisheye and narrow camera cable terminals were incorrectly installed in the cable harness connector, resulting in swapped camera views.
Risk: Swapped camera views can prevent the vehicle's cameras from detecting crossing objects and high-curvature lane lines, impairing the Autosteer and Automatic Emergency Braking (AEB) performance, and increasing the risk of a crash.
Fix: Tesla Service will correct the swapped terminals and recalibrate the cameras, free of charge. Owner notification letters were mailed July 8, 2022. Owners may contact Tesla customer service at 1-877-798-3752. Tesla's number for this recall is SB-22-17-007.
