Lexus LS400 Acceleration problems by year

The first time my ecu failed was when I was parked I want to drive and the engine would not go above 1000rmps. I got the ecu replaced this was around 2013. The second time was a month ago. I was driving home from work had a huge thud in the engine and the same thing my car could no longer go above 1000rpms and couldn't get threw the intersection. The car behind me had to slam on there breaks because my car had lost all power. I made it home and was able to get a tow truck. By the time the tow truck arrived the car...

Tl* the contact owned a 1993 lexus ls400. While driving at a low rate of speed, the vehicle accelerated at a high rate of speed when the brake pedal was depressed. As a result, the vehicle drove over a curb and crashed up a slope near a wooded area. There were no injuries and a police report was not filed. In addition, there was an abnormal noise heard near the engine compartment and front end of the vehicle as the vehicle surged at an extremely high rate of speed. The failure was reported to the insurance...

In approximately 1995, I experienced the "sudden acceleration" problem twice with my lexus ls. At the time, no one had ever heard of it and the dealer said he could not reproduce it and could do nothing. After that I was more careful with the floor mats and thought I had solved the problem. For the last 7 to 8 years, the car suddenly slows and stalls. I have repeatedly complained to new country lexus but they just say that they cannot reproduce the problem and don't know what it is. In june, it...

Twice, with two different drivers, this vehicle has accelerated/surged at a stop. The vehicle was able to be held steady by pressing the brake as hard as possible, but vehicle still surged and tried to move forward. On the first incident, the vehicle was put in neutral and continued to rev momentarily. After the first incident, the lexus oem floor mat (standard, not all season) was removed. The same event occurred again tonight with a different driver and the floor mat still removed. I am quite concerned this may be related to other toyota recalls. *Tr

As I was driving, my vehicle started accelerating on it's own. When I had previously checked the speed odometer it said 50. All of a sudden the vehicle started gaining speed. I took my foot off of the gas pedal and the speed kept accelerating. I pressed the brakes and the brakes did not work! The vehicle kept accelerating. I saw a side road and turned onto it. I kept trying to stop the vehicle and it kept going. I thought to pull the emergency brake and it slowed the vehicle considerable, but it kept...

Tl* the contact owns a 1999 lexus ls400. The contact stated that while driving 15 mph, he applied the brake due to traffic. However, the vehicle accelerated independently and crashed into the rear of another vehicle. The crash caused damage to both vehicles as well as an injured knee of the driver of the vehicle that was struck. The failure had recurred numerous times. The dealer was notified and he was informed the throttle body would probably need to be replaced. Also, he was informed that due to the type of...

I am reporting this because it might provide a clue to the toyota racing engine problem. On each of two days before I took my 1999 lexus 400 to the dealer for repairs, the engine would race at an estimated 4,000+ rpms and emitted a grinding sound as the car was started. After turning off the engine with the key, the car would restart without a problem. Strangely, the dealer did not record this particular complaint, but stated that diagnosis revealed that starter was failing. I was charged $990 for...

While driving my 1997 lexus ls400 in ca on the 605 fwy, west toward 210 fwy, all systems on the car locked (steering wheel, brakes, gas pedal) as I was changing lanes. I had no control of the car and after spinning several times ran into the center divider. I was very lucky not to go over the divider into oncoming traffic and be killed. I sustained neck and head injuries and the car was totaled. I was very lucky that I survived and that no other cars or people were involved. Early in 1998 I received a...

I'm writing this in the hopes that it may be of some help in toyotas brake problem. My 1999 lexus ls400 would loose throttle control, the engine speed would drop to idle regardless of what was done to the throttle itself. After 3 trips to the dealer, they found that the throttle position sensor would not work if it had become wet. They replaced the tps and that cured the problem. *Tr

Accelerator pedal sticks and engine continues to accelerate. I can only stop it by pushing on the brake hard, putting it in neutral or turning off engine. Sometimes if I have room in front of my car, I can stop it by pumping the brake. This has occurred several times. I cannot tell what causes it. Definitely not floor mat. *Tw

Acceleration stuck, rpms lock in at about 2000. Failure occurs about once or twice day, but usually only if the air condition is turned off. This has been going on for years now with my vehicle. I turn off vehicle and restart it to correct the problem and regain control of the accelerator, it almost always returns after restart. I believe this may be caused by fault in lexus electronic throttle system and since you all are finally investigating this I thought I should report it in case you would like to examine my...
