2 Electrical System problem of the 2003 Lexus RX300

Failure Date: 10/26/2016

I own a 2003 Lexus Rx300. After I had came from a completed stop while depressed on the accelerator pedal, the brakes began to lock with the abs brake light illuminated. The vehicle was diagnosed by an independent mechanic who stated the av pump failed or that it maybe something with the electronic control module. The vehicle was not repaired. The manufacturers were not made aware of the failure. The failure mileage was 320,000.

4 Electrical System problem of the 1999 Lexus RX300

Failure Date: 01/17/2016

On January 17th, 2016, I took my '99 Lexus Rx300 to church, parked the car, and joined the Sunday service. An hour after parking the vehicle (during which time it was not running or in use), I was told that there was smoke coming from it and went outside. Within minutes, the front end was bursting in flames. The fire destroyed the entire front portion of the car, including the engine, transmission, tires, and dashboard. I don't know what could have been the cause; it was seemingly random.

5 Electrical System problem of the 2002 Lexus RX300

Failure Date: 05/02/2014

6 Electrical System problem of the 2000 Lexus RX300

Failure Date: 09/15/2010

The moon roof motor has two functions, tilting open and sliding the entire glass panel open. When I attempted to use the slide panel open function, the panel did slide open, however it was much slower than normal operation and was accompanied by a grinding/clicking noise which never accompanied previous operation. An attempt to close the roof panel yielded an identical result. I then attempted to operate the tilt feature of the roof, which was also slow and accompanied by the previously mentioned noises. Attempting to close the roof resulted in no movement of the roof panel and a grating sound from the electric motor. Activating the switch while subsequently pushing down on the roof panel caused it to return to the closed position. I am now unable to open the roof due to fear of it being stuck in the open position and a subsequent accident in which the roof of the vehicle will bow and cause severe injury to passengers because the vehicle has posted warnings in the passenger compartment of its higher propensity to rollover in accidents or high speed maneuvers than average vehicles.

7 Electrical System problem of the 2001 Lexus RX300

Failure Date: 05/12/2010

I was driving a Lexus RX 300 and had exited the freeway. I pressed the brake lightly to decrease my speed but instead, the car unexpectedly accelerated. I then stepped on the brake fully but the car continued to accelerate by itself. I tried to slow the car by shifting the gears. . . Tried neutral, l1, l2, and even reverse but failed to slow down. I was going at high speeds, unable to stop, and very scared as I was on a street with many lights. After passing through a red light, I turned the car into the curb and dragged the wheels against the curb until the car came to a stop. I was very fortunate not to hit another car or people through two intersections. This occurrence happened at 3:55pm, may 12, 2010. The vehicle was towed to the nearest Lexus dealership for inspection and at this time, it is still under evaluation. This is the first time this car has demonstrated any unintended acceleration or failure of brakes to stop acceleration.

9 Electrical System problem of the 2000 Lexus RX300

Failure Date: 05/09/2007

I purchased my vehicle (2000 Lexus RX 300) in 2004 with less than 35,000 and every year since 2007 I have had issues with lighting. I have had the park light, break light, center stop lamp; center break light socket and bulbs all replaced. The unfortunate issue is that the lights have to be replaced every year sometimes twice a year because they continue to malfunction. I always take my vehicle to the Lexus of orlando dealership for testing, service and repair but they obviously never completely fix this issue. The most recent repair was replacement of th center brake light socket and bulb and reset on 4/14/2011 and in August 2011 on my way to the airport, an accident almost accrued due to my break lights failing to come while making a stop on a major highway intersection. I believe the problem is electrical, Lexus mechanic states the issue started with an untraceable problem in which the rear tail brake light stopped working and later on the park light and other lights thereafter.
