2018 Lexus IS300Acceleration & cruise controlEngine & coolingFuel system

When I accelerate from a stop or while moving on a roadway, the engine seems to stall. I'm not talking about the normal turbo spooling stall. It lasts for about 3 to 5 full seconds. When you need power to prevent an accident, you can't afford that time lag, as it could cause your death. The dealer told me that lexus says it's normal, they all do it. I don't feel any manufacturer would deliberately build and sell a vehicle that would put the occupants in danger of possible death. The dealer picked up the car and...

after five days called me to say nothing is wrong and they can't fix the problem because lexus company says it's normal. At this point I'm refusing to drive the car, it's extremely dangerous. I have only driven it about 188 miles since buying it almost 1 month ago. I called the dealer about my concern after having the car only 20 days.

2002 Lexus IS300Acceleration & cruise control

Accelerator failure: twice that I can clearly remember. First time happened in 2003 after gentle depression of the gas pedal, it seemed to push itself further and was stuck into the floor resulting in uncontrolled, max acceleration...This was mentioned to the dealer when I took it for service (ray catena lexus, larchmont, ny). After that, it didn't happen until the spring of 2008 where I was on the i95 on my way to work, in rush hour when the car suddenly went from about 40mph to 70 or 80. I managed to weave...

around traffic and drove on the shoulder while pressing full force on the brake pedal, pulled on the emergency brake and was finally able to get the car in park. After that occurred, I was followed off he highway by the help truck, took my car to a local mechanic for inspection and nothing was found...I immediately made an appt with the dealer but had to wait until the next day for service. In the meantime, it happened twice more on the highway but I was cautious and stayed away from cars and close to the shoulder. I took it to the dealer and was charged $100 to look at it (lexus of greenwich, ct), was told that it was the floor mat. Interestingly enough, this hasn't happened again and I still have the car but I am very worried that it might. *Tr

backwards from the impact of the crash. The vehicle continued to accelerate, crashed into the vehicle again and did not stop accelerating. Instead of allowing the vehicle to proceed into the highway she made the decision to crash the right side of the vehicle into a cement wall. The police were called to the scene and a report was filed accordingly. There were no injuries. The vehicle was destroyed. The vehicle was examined for floor mat entrapment by the manufacturer but showed no signs of interference. The failure and current mileage was approximately 50,000.

2004 Lexus IS300Acceleration & cruise control

On the morning of december 22, 2009, at approximately 6:30 am, on the northbound on ramp to i-25 at castle pines north, castle rock, co my 2004 lexus is 300 accelerated out of control. Stomping the brakes hard did not stop the acceleration. The only thing going through my mind at the time besides stopping the car, was the family of four in california that died in a rented lexus that accelerated out of control. I was about at the end of the on ramp, and I knew I could not merge onto i-25, when standing on the...

brakes stopped the acceleration, and I was then able to get the car stopped. After calming down, I drove my car into work ( about 20 miles) and called kuni lexus of littleton, co. Kuni lexus informed me at that time I needed to report this incident to toyota headquarters before kuni lexus could do anything, so I called toyota and reported the incident, then called kuni lexus back, told them what happened and arranged to have my car towed to the dealership. Kuni lexus had my car for a week, and did not find anything wrong with the car. They did note that my floor mats were not hooked into place. The floor mats were the first thing I checked, as I had heard the floor mat theory. The mats were in place when I checked them, before I had my car towed to the dealership. *Tr

Accelerator failure in a lexus is300 about two years my daughter got on a car accident at that time she mentioned that her accelerator got stuck. There has bee a few time that I felt that the accelerator got stuck while driving my car also. I called the dealer and the lexus company for the last 6 months and all they said is that my car is not involve in the recall. That don't mean that my car is not defective, or there need to be a fatal accident for them to take action. *Tr

I was sitting in my 2003 lexus is 300 4 door it was a rainy and unusually cool day so I rolled the windows down and with the car idling I listened to some music and contemplated where to eat dinner it being around 5.30 Pm. Suddenly the throttle opened up and the car shot off like a rocket over the curbing through some bushes and into a pond maybe 15 feet away the car was moving so fast that as it was sinking it moved out about 20 feet. It was completely submerged and I was lucky to unbuckle the seat belt and climb...

out the open window and swim to shore the only injury a sprained ankle. The car was a total loss. Amazingly I was given a ticket for wreckless driving that was dismissed as there were no witnesses the police and the insurance company insisted that cars don't surge like that on their own we know better I was treated like a criminal instead of sympathized with for almost drowning. It was not the mat or a sticky accelerator but I feel an electrical problem due to moisture that made the throttle open up the thing was also that the car was in park! Of course no lawyers would touch it I didn't get hurt bad and they said there was never any successful litigation against the manufacturers for sudden acceleration irregardless of cause. I just feel I need to tell my story and hope that it helps I have the vin # and all that if needed to track the factory made and maybe this will help substantiate a claim by someone who was hurt or help the family of someone hurt or killed. These companies care about profits not people and this culture much change. The other sad part was the police who assumed I did this on purpose I am not insane only an insane person would drive a car into a lake with them inside. That's the boynton beach police for you...Nice huh also I lost my job as a salesman as this took 3 months for me to get paid and I had no transportation! Do you think toyota will pay me for that? *Tr

2004 Lexus IS300Acceleration & cruise control

Car failed to stop at a red light under normal braking because engine failed to decelerate when pressure was removed from the pedal. Maximum force was applied to the brake pedal. The brake anti lock feature was activated and a collision with the stopped car ahead was barely averted. When stopped, the engine reverted to normal idle. The problem did not recur. Examination by a mechanic at the dealers shop failed to identify a computer fault or other cause. The car was returned without repair. I am not...

satisfied that a stuck throttle is not a repairable or abnormal condition. It seems to me be highly dangerous and merits more than a "well, its working now so come back when if it happens again." Sort of response. *Tr

2004 Lexus IS300BrakesAcceleration & cruise control

Dt*: the contact stated the brake and accelerator pedals were made of chrome plates that caused the driver to slip off the pedals during normal road conditions. The nature of the failure was permanent. The manufacturer refused to repair or replace the chrome plated pedals. Updated 11/30/2006 - the only shoes the consumer could wear to alleviate the slippage was athletic shoes, like sneakers, which have a rubber sole. *Nm

On 8/28/06, at approximately 8:50 am I was driving to work on a two lane, level, straight paved county road. I was driving my 2002 lexus is 300 that had just reached 26,000 miles. (This car has received all regularly scheduled maintenance services from lexus of reno and has not had any problems whatsoever. I am the original owner of this vehicle) the road was clear and dry. I was traveling at approximately 45 mph when I accelerated to pass another vehicle. As I passed, my car kept on accelerating even as I let...

up on the accelerator. I attempted to apply the brakes. The engine acceleration was so powerful, the car did not respond well to my attempt to brake, so I took my foot off the brake. The speed on the dashboard was 60 mph and accelerating. I applied the brakes again with all the strength I had and was able to pull the car safely off the road. The engine was racing even when stopped. I moved the shift into park. Even in park the engine was racing. I turned the engine off. My husband was following me and stopped. He drove it 1.5 Miles our office without incident. I then called the reno, nv lexus dealership where I purchased the car. The head of the service department called me back and suggested I have the car towed to the dealership. I asked him if he was aware of any other rapid acceleration problems with these vehicles and he said no. He said the 4 year warranty was up in 7/06 and I would have to pay for any repairs. That afternoon I had the car towed to the reno lexus dealership. On the evening of 8/28/06 I searched the internet and found that the nhtsa had investigated 2002-2003 lexus es 300 models for faulty throttles that may have caused rapid acceleration. So far lexus has not acknowledged a problem. I shared with the rep what I had found on the internet re: problems with rapid acceleration and that I was not picking the car up until lexus replaced the throttle. *Jb

2002 Lexus IS300BrakesAcceleration & cruise controlCrash

My 2002, lexus is300 had a case of sudden unintended acceleration that led to a crash causing over $10,000 worth of damages to both my car and the other persons car. I have seen other reports of other people wondering if the electronic throttle is suspect in these cases, however I personally believe that the real problem is only partly to blame on the electronic throttle. In my opinion, the problem is the likelihood of the pedal getting stuck under floor mats is too high, combined with the relatively "light"...

spring force on the gas pedal because it is a throttle-by-wire system which leads to the floor mat easily holding the pedal down to full throttle causing an accident. I say that this is "negligent pedal design on the part of the car manufacturer". I also believe that they knew this was an issue because they make reference to this in the owners manual on: pg.76 Where there is a caution that states "make sure the floor mat is properly placed on the floor carpet. If the floor mat slips and interferes with the movement of the pedals during driving, it may cause in accident." No manufacturer should be allowed to use that caution as a disclaimer to get away with negligent pedal design. They, fully well knowing that this is a safety issue, should have recalled those car models with a pedal design that has a high risk of getting jammed and redesigned the pedal so that it cannot get stuck by a floor mat. In all the cars that I've owned in the past, if a mat slips it just prevents you from applying full gas pedal, not the opposite of applying full pedal. I strongly move that toyota company recalls all these cars with this potential problem and fix it properly before someone get fatally injured or crippled for life. *Nm the dealer informed the consumer there were 2 codes that indicated there was a problem with the abs.

The engine will restart usually immediately after the failure. It happened about 100-150 times. The car has been to the dealership about 10 times within the last year. The dealership has attempted to repair the vehicle, but has been unsuccessful. The transmission is automatic. *Ak

Since I have owned the vehicle, I have had two incidents, which both occured randomly with no prior engine problems or indications of issues with the car, in which as I was accelerating, the gas pedal would continue to press down and pin itself to the floor. Both times, the gas pedal was literally stuck to the floor and not able to be loosened. The first time it occured, I pulled the emergency brake and jammed on my brake pedal until the gas pedal popped back up after about a minute pinned to the ground. The second...

time, I luckily had someone with me who instructed me to put the car in neutral and quickly turn off the engine one click so that I could brake and steer myself to safety. Thank god no one was injured in these incidents, but both occurences could have been horrible accidents. The car is a 2001 lexus is 300. Mileage at time of incidents: 1st incident-about 65-70,000 miles 2nd incident-about 80-85,000 miles. Both incidents occured within about 2-4 months of each other and the last incident from today would have occured about 1 1/2-3 months ago. I have only owned the car since october 2003. I do not know the previous owner or if there were any of these incidents reported before my ownership of the vehicle, and the vehicle was not purchased from a lexus certified pre-owned vehicle lot. I do have a scheduled appointment with my local lexus dealer coming up this month.
