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.

VOS-23-212023-07-10. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. This communication is a notice for software changes with the ODIS program for specific cars.
V2719012011894_22023-07-10. Service bulletin. ELECTRICAL SYSTEM. Battery Testing and Charging using Midtronics VAS6161 and or GRX3000 Vas Charger
V0118122014603192023-07-10. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Software Version Management (SVM) instruction.
TT3714012023-07-05. Service bulletin. ELECTRICAL SYSTEM. For communication faults set in various modules indicating loss of, or no communication with the mechatronic, please inspect the barrel connector lock for proper installation. If you find that the connector was not properly secured, inspect the terminals for damage. If no damage is found, reconnect the barrel connector and clear the faults.
TT2711022023-07-05. Service bulletin. ELECTRICAL SYSTEM. When diagnosing a low battery or no charging system concern, start by inspecting the SA1 200 amp fuse in the SA fuse block. DO NOT replace the generator. Perform a voltage drop test between threaded connections 508 and SA1 as shown in Figure 1. If the voltage drop is above .02V, disconnect the battery and remove the cables at the 508 connection and the SA1 connection. Check for continuity of the threaded plate connection between 508 and SA1. If fuse SA1 is found to have an open circuit, replace the fuse and check the threaded connections closely.
TT2614022023-07-05. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM); ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. Disconnect both O2 sensors (front and rear), start engine and let idle. Check MVB's 41/4 and 136/4 and verify have both changed from a 1 to a 0 (you may have to drive the car 4 miles to get them to reset to 0). Also a key cycle may be required for values to reset. This forces the ECM to re-learn the O2 sensor adaptation. Once MVB 41/4 and 136/4 read 0, re-connect the O2 sensors, road test and recheck for faults.
TT2613032023-07-05. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. Use of aftermarket air filters such as cotton bed steel mesh or cone style, can cause the MAF sensor to not read accurately, affecting vehicle performance and critical monitoring functions for the diesel particulate filter. This can also result in premature DPF failure. Only use factory air filters. The use of aftermarket air filters is not supported as the system was designed and calibrated to work with factory air filters.
TT9714022023-06-13. Service bulletin. ELECTRICAL SYSTEM. The DLC is intended for use with diagnostic scan tools and by emissions testing stations. However, aftermarket devices (i.e., drive data recorders) that connect to the DLC have now become available.
TT9614022023-06-13. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. When replacing the complete vehicle lock set (all vehicle keys and lock cylinders) for any reason, be aware that the ?Adapt keys? test plan will not allow the new keys to adapt to the vehicle. Instead, perform the test plan for ?New identity?. During this test plan, make the appropriate selection to indicate only the lock set has been replaced, as shown below in figures 1 and 2.
TT9114012023-06-13. Service bulletin. EQUIPMENT:ELECTRICAL:INFOTAINMENT; ELECTRICAL SYSTEM. If a 2014 Model Year vehicle equipped with the Car Net? system experiences a customer complaint where the system is placing false outbound calls, it is possible that the cause is a loose or unplugged connector at the 3-Button Assembly in the overhead console. If this concern is verified and there is no damage to the terminal(s) or connector(s), simply secure or plug in the loose connector.
TT911309a2023-06-13. Service bulletin. ELECTRICAL SYSTEM. On some 2014 Volkswagen vehicles equipped with CarNet, ODIS may not display 75 ? Emergency call module & comm unit in the self-test menu.
