Unintended acceleration
#47
13 SWB F-Sport RWD and I can tell you for a FACT that it's true. Happens to me almost every time I lightly tap the brake to disengage cruise control. It's to the point now where I just disengage from the control stalk because I don't trust the brakes to disengage it. It only happens when I use cruise control. I actually added it to a post I created a few months back when I first got the car. Didn't get much response, probably because it wasn't the main reason I was posting.
So FWIW yes it is a thing and just because it hasn't happened to you doesn't mean it's "operator error/pressing brake and accelerator" etc. All these different people who are total strangers and have been driving for YEARS saying the same thing isn't just happenstance. The LS is still a machine and by that, a machine is prone to quirks and gremlins just like an other brand. So if you have a way to help please do, if not, then save the 2 cents because it's a legit issue. Thanks every one for sticking to your guns and speaking on it.

Agree with the others, your issue has nothing to do with what we’re talking about

Years ago my father almost had an accident when barrowing my car, not my Lexus, but he did not realize he was pressing the gas pedal while hitting the brake. One could argue the size and location of the pedals in some vehicles might be more conducive to the problem. I have also never experienced this in any vehicle I have owned over the last 25 years. Big feet and big shoes or boots probably don't help either.

I have also been in the car with an older driver who thought he was putting his foot on the brake but was putting it on the gas, very scary and certainly seems like the car is accelerating by itself.

Braking only
Just to set the facts straight! All of my unintended accelerations, including the last while parking in my garage, occurred while braking to a stop (in traffic) ! My foot was totally on the brake, and if not for that, the car would have hit the car in front of me. The placing the car in neutral was to stop the engine from revving and disconnecting from the transmission. The brake held the car from moving and I used all of my force on the brake pedal to hold the vehicle from moving!!!!
Some one out there must have had this same experience!!!
Come forward, it feels good.

You thought your foot was on the brake, but it was not. This has been investigated many times by Independent government agencies and in every instance they found that unintended acceleration was caused by driver error. They did an exhaustive investigation into unintended acceleration in Toyota and Lexus products and determined that there was no issue or failure.
If your foot foot was firmly on the brake even at full throttle your car would not move. Try it. Go into an empty parking lot, put your left foot all the way on the brake and give it full throttle. It won’t go anywhere.
The most powerful thing on any car are the brakes. The engine is less powerful than the brakes.

Apparently their brakes are not strong enough, The dealer should advise them to upgrade to F Sport Brembo brakes for several thousand dollars just to be extra safe or trade their car for something newer

If you do some research into unintended acceleration claims across all manufacturers you'll find that all of them have been linked back to operator error in one way or another. I've actually been in a car where the driver when backing up unintentionally slammed the accelerator instead of the gas. Scary to be sure and he also did not immediately realize what he had done.
After the whole Toyota accelerator fiasco numerous magazines tested to see if the driver applied the brake when accelerating at full throttle what would happen. What happened was the car stopped, the accelerator could not over power the cars brakes. People who have this issue often say they apply the brake fully, well it's been proven that had they done that the car would stop even with the throttle at WOT. So, the logical result is that while they thought they were full on the brakes, they were actually full on the gas.

So, the logical result is that while they thought they were full on the brakes, they were actually full on the gas.
Having been around the block a few times, I have come to understand the core issues with "unintended acceleration" It has been proven that the issues were indeed driver error, NOT electrical error. Lexus and Toyota have NOT been the first manufacturers to defend the "unintended acceleration" storm. AUDI nearly went bankrupt in the late 80s by the same claims. It has been proven that the pedal placement may have been too closely spaced and drivers were pressing the accelerator instead of the brake. The term became known as "pedal misapplication". So you could argue it was a bad design that caused the CONFUSION. In Lexus' cases, it was determined to be the floor mats sliding under the "drive-by-wire" accelerator pedals. The "drive-by-wire" pedal is very sensitive to position, angle, etc.
Here were the findings of the Toyota investigation: On February 8, 2011, the NHTSA, in collaboration with NASA, released its findings into the investigation on the Toyota drive-by-wire throttle system. After a 10-month search, NASA and NHTSA scientists found no electronic defect in Toyota vehicles. Driver error or pedal misapplication was found responsible for most of the incidents. The report ended stating, "Our conclusion is Toyota's problems were mechanical, not electrical." This included sticking accelerator pedals, and pedals caught under floor mats.
So in summary, the cars do not electrically accelerate by themselves.
