Some customers may complain that the power liftgate (PLG) may open unintentionally while the vehicle is parked or stopped. Due to the shape of the 7th generation remote transmitter, the power liftgate button may be long pressed unintentionally in a pocket or a bag. To eliminate this concern, the keyless control specification has been modified. The button press time has been increased from 0.5 seconds to 1 second.
SA-016-242024-04-03. Service bulletin. SERVICE BRAKES, HYDRAULIC. Some vehicles exhibit brake related concerns such as brake noise, brake judder or brake dragging. If you encounter a customer complaint for any one of these symptoms, refer to the following information to understand why symptoms may occur, and to better assist the customer in resolving their specific brake concern.
PF-24-032024-04-03. Service bulletin. POWER TRAIN. Due to limitations, certain vehicles from 2016 to current models might display an inaccurate transmission part number in the Global Electronic Parts Catalog (GEPC). To provide support in such cases, a temporary lookup guide has been developed for assistance.

09-006-242024-03-06. Service bulletin. STRUCTURE:BODY:HATCHBACK/LIFTGATE; LATCHES/LOCKS/LINKAGES. Some vehicles may exhibit a creaking or clacking noise when operating the power lift gate (PLG). The noise may be caused by the following: Creaking noise: Dust and dirt accumulates on the sealing portion of the PLG drive unit, reducing sealing performance. Snow and water may enter the PLG drive unit. Humidity then causes rust inside of the unit, resulting in noise. Clacking noise: Since the grease applied on the spring end of the PLG drive unit is insufficient, interference noise is caused when the spring end interferes with the spring guide. The noise has been eliminated by the following mass-production changes: Creaking noise: The sealing structure has been modified to prevent dust/dirt from entering the unit. Clacking noise: The production procedure of the PLG drive unit has been modified to apply sufficient grease to spring end.
06-001-242024-02-01. Service bulletin. STEERING. Some customers may complain about a creaking, knocking, rattle or clunk noise coming from the steering column while driving. A steering column nut loosens due to excessive load when driving on irregular roads. To eliminate this concern, the tightening torque for the steering column nut has been increased.
01-005-23a2024-01-06. Service bulletin. ENGINE AND ENGINE COOLING. Some customers may experience the check engine light ON with DTC P0126:00 (Thermostat stuck open) and one or more of the following symptoms: The engine takes longer to warm up The engine temperature gauge fluctuates The low coolant temperature indicator (blue) light stays on longer or comes on while driving Poor heater performance, especially at idle

SA-079-232024-01-05. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; VISIBILITY. Some customers may complain about color discrepancies (brightness differences) of the image displayed on the screen when using the 360°view monitor. As this phenomenon is not a system failure, do not make any repairs or replace any parts.
09-041-232023-12-05. Service bulletin. EXTERIOR LIGHTING. Some customers may complain that the headlights get foggy or have water spots inside. This concern may be caused by the anti-fog coating not preventing inner condensation under certain situations. To eliminate this concern, the anti-fog coating performance was improved.

If you encounter any type of electrical concern (e.g, dead battery, engine no start, DTC(s) stored...), interview the customer before proceeding with normal MGSS diagnosis by asking if any aftermarket devices have been installed. Aftermarket devices may be the cause of the electrical concern. Below are a few examples of unusual electrical concerns caused by aftermarket devices.
05-005-232023-11-01. Service bulletin. POWER TRAIN. Some vehicles may exhibit a chirp noise (stick-slip noise) from the automatic transaxle (AT) when shifting from 3 to 4 while driving. This may be caused by the automatic transaxle fluid (ATF) being contaminated by iron powder due to excessive wearing of the lock up clutch in the torque converter.
02-003-232023-11-01. Service bulletin. SUSPENSION. Some customers may complain of signs of oil on the struts or shock absorbers. In most cases the oil that is present is normal, and a result of the oil that remains on the shaft during the normal sweeping process of the shaft seal. Follow the inspection guidelines below to determine if the condition is a result of the normal sweeping process or a failure of the shaft seal.
SA-039-23a2023-10-05. Service bulletin. STRUCTURE; VISIBILITY:POWER WINDOW DEVICES AND CONTROLS. Some vehicles may experience exterior trim heat damage when parked near a glass building or Low-E windows. This may be caused by the sun's reflection.
SA-003-23a2023-10-05. Service bulletin. SERVICE BRAKES. Some vehicles exhibit brake related concerns such as brake noise, brake judder or brake dragging. If you encounter a customer complaint for any one of these symptoms, refer to the following information to understand why symptoms may occur, and to better assist the customer in resolving their specific brake concern.
04-001-23b2023-10-04. Service bulletin. SERVICE BRAKES. Front Brake Noise Symptom 1: Some vehicles may exhibit a click noise when first moving forward or reverse from a stop OR when first applying the brakes while moving forward at slow speeds. This is caused by deteriorated grease between the brake pads and the shim, the front brake pads move upward/downward along with the brake rotors during brake application. When the vehicle moves or the brakes are applied the next time, the front brake pads move to the other side, which causes a click noise. Front Brake Noise Symptom 2: Some vehicles may exhibit the brakes having an unusual noise or vibration when applying the brake. This is caused by rust on the brake disk plate’s surface. Rear Brake Noise Symptom 1: Some vehicles may exhibit a squeak noise from the rear brakes while braking lightly and occurs more frequently when driving at slow speeds. The noise is caused by poor contact between the guide plate and the mounting support. To eliminate this concern, the material of the pads has been changed to copper-free and the specification of the shims has been changed to a coated spring with tape. Rear Brake Noise Symptom 2: Some vehicles equipped with an electric parking brake (EPB) may exhibit a grinding noise from the rear brakes when braking. This may be caused by the rear brake pads not having the capability to remove the rust from the rear brake discs. The red rust accumulated on the discs is exposed to high temperatures during braking, and consequently the rust turns black. As the black rust is too hard to be removed by the brake pads, the rust progress is accelerated, resulting in the grinding noise.
SA-050-232023-09-05. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Some customers may complain about scratches on the instrument cluster lens.
