Service bulletin WSTCAE169-2018
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.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
| CALABSECU | 2020-06-06. Service bulletin. Customer Advisory Letter for ABS ECU Software Update. The Enhanced Stability Control (ESC) function within the ABS module that applies to the vehicles in your possession needs to be updated for the axle spread values. The ESC with the current values functions as it should, but should be updated to ensure proper calibration in the future. |

| SBW54-075 | 2020-04-18. Service bulletin. Service Bulletin for Lengthening the Backup Light Harness. Though the back-up light harness is long enough to connect to the backup light switch, it may be short enough that the wire seals in the connector can be stressed. Moisture entering through the seals can cause corrosion, resulting in a bad connection and/or failure of the switch. As a result, backup lights and, if equipped, the backup alarm, may not function when the vehicle is shifted into reverse. |
