ENGINE
My vehicle has the V6 twin turbo engine that’s been recalled on other years and models and was diagnosed with an internal engine failure. The mechanic at the dealership couldn’t figure out the problem so an expert TAS Lexus specialist was called in and couldn’t figure out the problem either. They’ve had the car for 3 months and since they don’t know how to fix it they are telling me to just replace the engine with a used engine at a cost of $25,000. The vehicle is just out of warranty and Toyota/Lexus is refusing to cover any of the costs. The vehicle was serviced regularly so this shouldn’t have happened. This is a common problem with this model of engine. I believe it’s a design flaw as this model engine is assembled at different plants/locations and over long periods of time that would indicate a design flaw and not due to Toyota’s official stance of debris left in engine block during assembly. Toyota should recall and replace all these engines at no charge to the owner of the vehicle.

EXTERIOR LIGHTING
Both headlight assemblies on a 2021 Lexus LS 500 show external lens delamination, along with visible condensation inside the sealed units. The vehicle has been garage kept, has not been involved in any accidents, and has no external damage to the headlight assemblies. The outer lens surfaces are deteriorating, and moisture is present inside components that are designed to be sealed. The condition has progressively worsened over time. These issues reduce headlight clarity and light output, negatively affecting forward visibility during nighttime driving and creating a potential safety hazard.

SEAT BELTS, SEATS, AIR BAGS
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.

TIRES:TREAD/BELT
OEM Bridgestone Turanza EL440 RFT 245/45 R20 These tires have not retained recommended air pressure for more than a few weeks at a time since new. Inspection earlier this year by a Bridgestone dealer found no problem with a tire that had lost 5 psi in a week. The tire subsequently began making a rotational noise that the Lexus dealer diagnosed as a slipped belt. Having replaced the defective tire, I now have the same noise symptoms arising in another tire. The dealer can find no reason for the chronic air loss in the two left side tires which, given the developing rotational noise, I expect will soon have similar belt failure. Dealer personnel admit that these tires are problematic. Bridgestone customer service has been unresponsive.
