Service bulletin TSB_CLI048_R1

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.

TSB_CLI053_R1	2023-11-03. Service bulletin. TECHNICAL SERVICE BULLETIN: HVAC BLOWER MOTOR CONNECTOR REPLACEMENT - This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides information to replace the Heating, Ventilation, and Air Conditioning (HVAC) blower motor connector on some 2019-2023MY Forte (BDm) vehicles produced from July 09, 2018 through present, which may experience the air conditioning function inoperative. The blower motor connector pins may have poor pin tension. Poor pin tension occurs when the female pin is slightly open which will not allow for a proper electrical connection. While driving, the road conditions can cause the connector pin to slightly move within the connector and will intermittently make contact with the male pin. This can cause excessive circuit resistance, causing the blower motor to become inoperative. Follow the procedure outlined in this publication to replace the HVAC blower motor connector.

New/revised sections of this bulletin are indicated by a black bar in the margin area. When servicing windshield wipers on the below listed vehicles, including during PDI, ensure to raise the wiper arms to a vertical position to avoid damaging the paint on the rear edge of the hood.
TSB_CLI048	2020-05-05. Service bulletin. TECHNICAL SERVICE BULLETIN: - PARTIAL REPAIR; COMPRESSOR FIELD COIL ASSEMBLY INSPECTION AND REPLACEMENT - This bulletin provides information regarding A/C Compressor Field Coil Assembly inspection and replacement on some 2017-2020 Forte (YDm, BDm) vehicles. Follow the diagnostic procedures in this bulletin to isolate air conditioning compressor faults such as open field coil circuit. Kia has made the Field Coil/Bolt available as serviceable item.
TSBCLI044	2019-04-06. Service bulletin. TSB: SERVICE ACTION: A/C REFRIGERANT OVERFILL (SA372) - This bulletin provides the procedure to recover and recharge the air conditioning system on certain 2019MY Niro Hybrid (DE HEV) and Niro Plug-in Hybrid (DE PHEV) vehicles, produced from July 9, 2018 through December 21, 2018, which may experience poor air conditioning performance due to a possible overfill of refrigerant. Follow the procedure in this bulletin to recover and recharge the air conditioning system with the proper amount. Kia is requesting the completion of this Service Action on all affected vehicles including dealer stock, prior to delivery.
PS299_R3	2018-10-09. Service bulletin. PITSTOP - CORRECT PROCEDURE FOR RAISING WINDSHIELD WIPERS - When servicing the windshield wipers on the listed vehicles below during PDI, make sure to use the procedure outlined below to raise the wiper arms to the fully vertical position in order to avoid damaging the paint on the rear edge of the hood. It is important to note that the wipers on these vehicles are recessed under the hood to provide better appearance and reduced wind noise characteristics. This procedure applies to both key start and SMK type ignition systems.
PS498	2017-08-02. Service bulletin. PITSTOP: ANTI-CONDENSATION LOGIC ? NORMAL OPERATION, DISABLING, AND ENABLING - Some Kia vehicles starting with 2016MY and all Kia vehicles, after and including 2017MY, incorporate an anti-condensation logic to prevent the interior windows from becoming excessively fogged. The HVAC control head in these vehicles monitors ambient temperature to determine which settings will best prevent the windows from fogging. If the system detects lower ambient temperature (about 60°F or below), the anti-condensation logic may automatically set the air intake mode to FRESH, depending on the other HVAC settings. The anti-condensation logic is also designed to ensure that air intake mode is set to FRESH, as long as all conditions are met. If the user changes the air intake to RECIRCULATION, the anti-condensation logic will take control again after 5 minutes, and change the air intake mode back to FRESH. If this results in an undesired operation, the logic may be enabled or disabled by following the procedure below.
PS493	2017-08-02. Service bulletin. TSB: DEFOGGING LOGIC ? NORMAL OPERATION, DISABLING, AND ENABLING - Starting with 2010MY, all Kia vehicles, except Rio (JB), incorporate a defogging logic to prevent the interior windows from becoming excessively fogged. Depending on the specific model, the HVAC control head monitors ambient temperature and/or cabin humidity to determine which settings will best prevent the windows from fogging. If the system detects lower ambient temperature or higher cabin humidity, the defogging logic may automatically switch ON the A/C, and/or set the air intake mode to Fresh Air. If the user changes these settings, the defogging logic will take control again after 3 to 5 minutes, depending on the procedure in this publication.
PS472R1	2017-08-02. Service bulletin. PITSTOP: HVAC VENTILATION LOGIC OPERATION - Starting with 14MY Soul (PS) (with the exception of PSEV) and complete new models such as K900 (KH), Sedona (YP), Sorento (UMa), Optima (JFa), Sportage (QL), and 17MY Forte (YD, YDm), etc., equipped with a sunroof, a ventilation logic has been applied in order to prevent exhaust gases flowing into the vehicle due to the pressure difference (inside vs outside) that is generated when driving with the sunroof open. This logic allows the system to automatically switch from RECIRCULATION to FRESH mode when the sunroof is open.
PS266R1	2017-02-08. Service bulletin. PITSTOP: HVAC RECEIVER/DRYER - DESICCANT REPLACEMENT - IN THE EVENT OF A HVAC SYSTEM CONCERN IN WHICH METAL PARTICLES OR SHARDS HAVE CONTAMINATED THE SYSTEM, THE DESICCANT OR THE ENTIRE A/C RECEIVER/DRYER ASSEMBLY MAY NEED TO BE REPLACED. THIS IS DUE TO THE FACT THAT IT MAY BE IMPOSSIBLE TO REMOVE ALL METAL CONTAMINANTS FROM THE RECEIVER/DRYER DURING THE A/C FLUSHING PROCEDURE. REFER TO THE INCLUDED TABLE FOR DETAILED INFORMATION ON COMPONENT REPLACEMENT BY MODEL. IF YOU SUSPECT A PLUGGED EXPANSION VALVE, THE INLET SCREENS CAN BE CLEANED. IF THE VALVE IS NOT EQUIPPED WITH AN INLET SCREEN AND IS RESTRICTED, THE EXPANSION VALVE MAY ALSO NEED TO BE REPLACED.
