I noticed when I would pull out of my driveway I would hear a knock when I put the car in reverse also; I was driving home from work one evening and it was raining I was on a busy freeway, I was beginning to slow down and the brakes went all the way to the floor and a loud rubbing noise occurred I slid for about a min. Thank god I was able to pull off the freeway, this has occurred several times, I prepare for it now by being very careful. This is my only means of transportation. Just the other day I was on a business trip and the guy that valet parked my car told me he almost hit another car, because of the brakes going all the way down. I have had the brakes change and 2 sets of tires within the last 2 yrs neither was the problem. Please help.

My 17 year old daughter was driving my 2003 Lexus in town. We have never had any previous similar incidents, and have not experienced the same thing since. She had stopped at a stop light, but was too far back, so she wanted to pull up a little. She took her foot off the brake, and the car moved forward. She repeatedly pushed the brake, but they did not work. The car stopped when she hit the car in front of her. I had the car checked after the accident, but they couldn't find anything obvious. However, she, and the other passengers, have verified that she repeatedly pushed the brake to no avail.

2003 Lexus ES 300 with brake failure. Consumer states that the brake failure had occurred a few weeks after having the front and rear brakes replaced. Dealer states that the vehicle was tested and no defect was found. While backing out of the carport, which required the consumer to have his foot on the brake, the vehicle while in reverse began moving backward slowly and the brakes failed to stop the vehicle. The consumer turned off the ignition, but did hit a tree, which cause a slight dent to the trunk door. The explanation given to the consumer was that the floor mat may have slid under the brake pedal and over the gas pedal.

Vehicle lurches forward when brakes are applied. This caused consumer to hit a sign. Dealership checked brake system and found no codes of defect. Also, check engine light was on due to a misfire on the cylinder.
