  Electronic stability control (esc)

  While this vehicle was not included in the safety reacall bulletin regarding un-intended acceleration, my vehicle no exhibits the issue that, while in motion, the brake and accelerator pedals can be pushed simultaneously, possibly causing a vehicle accident. I feel my vin should have been part of the safety recall list.

  Rear center and the rear driver's seat belt were installed incorrectly by the manufacturer. the only way the seat belts will fasten IS if they are crisscrossed, and then depending on who fastens the belt first, will determine which occupant will be trapped in seat belt. *ak

  I own a 2003 lexus GS 430 vehicle. during the time that I have owned this vehicle, I continue to experience vibration and brake and wheel wear on the front end assembly. the dealership has aligned the front end and changed tires, but the problem IS repeating. I believe that the vehicle IS improperly designed either to accept 17 in. Tires or to handle a 4.3 liter engine. the dealership insists that all you have to do IS rotate tires every 5,000 miles and there IS no problem, but this IS not the case. as a result of the run-out and out of balance condition in the front end of the vehicle, the braking IS unrepeatable, and, I believe, causes a sever safety concern. the problem happens within 3,000 to 4,000 miles of an alignment. I believe that this problem IS endemic to lexus GS 430'S with 17 inch tires and believe that the dealership IS not interested in confronting a design problem. I am asking that this be investigated. I also intend to contact toyota directly. *la

The aforementioned bulletins are obsolete, and any printed versions should be discarded. Be sure to review the entire content of this service bulletin before proceeding. This Service Bulletin provides best practice procedures for vehicle pulling complaint, diagnosis, and repair for 2002 ? 2021 model year Lexus vehicles. This information supplements Repair Manual procedures when the symptoms are: ?Vehicle Pulling: The vehicle moves to the right or left when the driver holds the steering wheel while driving straight ahead without exerting steering effort. ?Steering Wheel Off Center: The vehicle travels straight, but the steering wheel is not pointed straight ahead. The vehicle is not pulling. Before repairing a vehicle pulling to one side, it is necessary to clearly identify the cause of the pulling condition. Frequently, pulling to one side is diagnosed as a wheel alignment concern. However, the actual cause may be related to the lateral force generated by the tires, vehicle damage, road crown or worn components. Performing a wheel alignment when tire force is the cause could result in the wheel alignment being set at a value outside of specifications. This could then cause other problems such as uneven tire wear, etc. A customer may notice a pull to the left when in the left lanes of travel and notice a pull to the right or no pull when traveling in the right lanes of travel on the very same section of roadway. This road crown effect is environmental and cannot be corrected with suspension adjustments or any other wheel or tire modification discussed in this bulletin.

• 10132074Beginning in 1998, Lexus introduced side airbags as optional equipment. Lexus does NOT recommend replacement of original seat covers with non-Lexus leather or other seat cover materials on vehicles due to the following: Seat covers NOT recommended by Lexus may affect side airbag performance, in general or in part, during an accident. Modifications that negatively affect side airbag performance can result in severe occupant injuries. Seat covers are an integral part of this safety system. Replacing fabric seat covers with non-Lexus leather or other seat cover materials may compromise the effectiveness of this safety system. The design of the seat is complex, integrating safety and strength with comfort and luxury. Lexus strongly discourages modifying original equipment seats that have optional side airbags. Additionally, Lexus strongly advises against the installation or use of aftermarket seat covers, which could impair the performance of the side airbags in the event of an accident.
