Service bulletin B640518
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.

| B640422 | 2024-03-02. Service bulletin. An interference noise (groaning noise) can be heard from within the heating and air-conditioning unit in thecenter of the instrument panel. The groaning noise always occurs when either a ventilation flap, air stratification flap or the recirculated airflap moves to a different position. Due to the complex design of the heating and air-conditioning unit, the kinematics causing it (top or bottom,left or right) may not be able to be precisely located. Depending on the vehicle model, the number of servomotors (and the associated kinematics unit) varies.Various models use either 2 or 3 servomotors. |

| B511722 | 2023-06-26. Service bulletin. Due to the semiconductor supply, the Local Interconnect Network module in either of the exterior mirrors was switched to another controller. That one provides an imprecise voltage measurement, which the main controller interprets as a fault. |

| B511722 | 2022-12-12. Service bulletin. Due to the semiconductor supply, the Local Interconnect Network module in either of the exterior mirrors was switched to another controller. That one provides an imprecise voltage measurement, which the main controller interprets as a fault. For the driving cycle, the customer may lose the display in either mirror and the Lane Change Warning function and, if installed, other functions such as- Side collision warning; Lane Change Assistant; Steering and Lane Control Assistant; Emergency Lane Assistant Hands Off 60 Assistant. |
