2021 Lexus LS Complaint Log

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.

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.

I was driving and my sunroof exploded sounding like a gun shot. The sunroof shattered and was blown apart on all 4 sides. Glass fell in my face and all over me

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.

The car slipped because of tread wear on the inner side of all four tires. Car has manufacturer installed tires.
