Example complaints

“My car, Lexus IS 350, has a condensation problem inside the headlight housing on both sides. I bought the car approximately a year ago. The problem first occurred to my car about 2 weeks ago. One of the headlights are permanently out. Because of the water, not only the headlight but ballast and the ecu are failed to operate properly. It is a manufacturer defect as even the dealership and the Lexus customer satisfaction center admitted. However, Lexus refused to provide the full service. They offered to provide $1,000 when the total fixing cost will be around $1,500 for one side. …”

“The aux cable to plug a 3.5mm jack from audio headphone / speaker cable does not work. It plays music only in the front right door speaker, does not play anywhere else. All of the speakers work fine when on radio or cd mode but the aux cable seems to be malfunctioning. I have searched this problem online and spoken with others who have the same model of Lexus (is350 2007). It is a common occurrence. It would be great to get this fixed. Thank you.”
