My 2025 Lexus Ls500, with only 500 miles, has two serious defects in the front passenger seat, creating a safety hazard. The massage function is non-functional, grayed out in the infotainment system, and the seat belt fails to tighten or retract, leaving significant slack when buckled. Issues appeared during normal city driving (dry conditions, <10 mph, no accidents or modifications). The seat belt, when pulled and buckled, remains loose with several inches of slack, failing to secure an occupant. This was tested 5+ times, stationary and moving. The massage feature (part of the 28-way adjustable seat package) is grayed out, indicating a system fault, likely in the seat’s control module or air bladders. No warning lights (e. G. , srs) are on, and no diagnostic codes are retrieved yet. The loose belt poses a severe risk in a collision, as it cannot restrain the occupant, increasing chances of ejection or injury (e. G. , head/neck trauma). A dealer visit is planned under warranty, but this manufacturing defect in a new vehicle is alarming. Vehicle was bought new from Lexus of glendale, glendale, CA. Photos of the grayed-out controls and slack belt are available. This may affect other 2025 Ls500s and warrants investigation to prevent injuries or fatalities.
Driver's seat is painful after 15 minutes. It is available for inspection. Causing shifting of position and pinching of nerves reduced feeling to foot. Problem has not been confirmed by dealer. Vehicle has been inspected by manufactures dealer. Problem first appeared 7/26/2025.
Large lump/lumps on the lower left / bottom portion of the driver's seat, protruding from the seat bottom closest to the lower bolster. As a direct result my left leg loses its circulation, it causes numbness and muscle pain in thigh and groin due to this. Regardless of seat adjustment the lump / imperfection in the seat cushion is present. This can become dangerous during longer drives and trips. According to the Lexus forums this is a known issue in the 2018-2024 Ls500 that Lexus is apparently aware of but has not resolved or seriously looked into. My Lexus service advisor admitted that she has heard of this problem from other Ls500 owners and said that the issue has been reported to Lexus. Despite this known issue, no technical service bulletin has been issued by Lexus and no corrective action has taken place. The imperfection in the seat can create a safety issue during trips due to it causing numbness, pain and discomfort in the leg. This is not an issue one would expect in owning a $100k plus vehicle.
