Nissan Maxima seat noise issue requiring seat frame replacement at 4,000 miles on Nissan Maxima

Some Nissan Maxima owners report experiencing a rattling noise coming from the engine bay towards the passenger side, particularly noticeable in the morning when the engine is cold and on bumpy roads, which typically disappears after a few minutes of driving. Additionally, some owners have reported a low squeal noise inside the cabin when running the heat on a medium to high fan setting, which appears to be more central rather than localized behind the glove box area. There are also accounts of a slight vibration felt in the seat that coincides with the noise, making it difficult to pinpoint the exact source due to the seat's leather covering and surrounding metal components. While a technical service bulletin exists to address certain issues, details regarding seat frame replacement at 4,000 miles are not clearly stated. Owners experiencing these issues are advised to consult a certified Nissan technician or dealership for a thorough inspection and appropriate resolution.
