Service bulletin TSB003120Rev2

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.

21TC06-RL_Publis	2022-01-18. Service bulletin. RL: One of the Pre-Collision System (PCS) features in your vehicle is called ?pre-collision brake assist.? When you apply some pressure to the brake pedal, this feature of the system can automatically help further reduce speed if sensors detect the possibility of a crash. Due to incorrect software programming, there could be a delay in the activation of pre-collision brake assist, resulting in less overall vehicle speed reduction. However, the other features of PCS (the pre-collision warning and pre-collision braking) are not affected by this programming error.
