Electrical System problem #1

The contact owns a 2007 Lexus is 350. While driving 35 mph, the air bag indicator illuminated without warning. Sewell Lexus in fort worth, texas requested that the vehicle be brought in for diagnostic testing. The vehicle was diagnosed by an independent mechanic as having squib circuit failure inside of the air bag, which caused the srs indicator to illuminate under code: b1861. The independent mechanic stated that in the event of a crash, the squib circuit failure could potentially disable the air bags. The manufacturer was not made aware of the issue. The failure mileage was 141,896.

Electrical System problem #2

When sunroof is open, sometimes it will not shut.

Electrical System problem #3

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.

Electrical System problem #4

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. I am also aware of the class action that are going on for RX from 2004 - 2009 model. As they are suffering from the same problem, many Lexus owner are having this issue. This is certainly a manufacturer defect but they are refusing to provide the service because my manufacturer warranty has expired. Now, it is obviously dangerous to drive at night due to their mistake. I strongly feel that it is not the matter of factory warranty, but the business ethics and the responsibility of Lexus. Since the water damaged the ecu, cause the problem that there shouldn't have been, they need provide full service for their customer. I am filing my complaint due to achieve the right as a customer, please take a close look at the issue.
