If the car is stalling then thats not normal Hil start will never turn the vehicle off. It will only hold the vehicle in idle. but if your is stalling then thats an issue the dealer needs to address.

BTW, when the car stalls, did you press both the accelerator and brake? or simply smashing the brake pedal to the floor

 

Does't sound like he means the car "stalls", just won't roll when he lets off the brake.

As others have stated, good thing he came on here and asked, before wasting his time at the dealer.

 

Simultaneous application of both accelerator and brake pedals (at certain speeds and driving conditions) will purposely cut engine power. I do not know what the 'certain speeds and driving conditions' are that cause this event of the engine to cut power. However, if [having] stopped on a hill and when trying to get started without having the vehicle roll backward the driver applies both the accelerator and brake pedals at the same time it may cause the engine to stall, or to feel like it has stalled.

 

I found this about those "certain speeds and driving conditions":

Thanks for that! I do recall reading that information some time ago. Thanks again for the refresher.

 

When you step on the brake and gas at the same time your engine cuts power to prevent unintended acceleration. This technology is call smart stop technology. When toyota vehicles accelerate and would not stop because of a stuck gas pedal it made toyota design a system that will prevent this by cutting power and overide the gas pedal to safely stop even though the gas pedal is stuck at full throttle.

The side effect of this tech is you can no longer brake torque your car to get the car to launch harder during a drag race.because the car senses that you want to brake and accelerate at same time an will cut power which is bad for racing

 

^^ Smart stop doesn't work unless you're going at least 5 mph so you should still be good to go.

 

For some reason when i hold the brake moderatly and floor the gass pedal I lose power. I even tried it the other way aroung and press lightly on the gas pedal so i can have some rpms on thd take and under 5 mph i still lose engine power. I even tried this while in park with emergency brake on and as soon as i rev the engine while stepping on the brake I lose engine power even though I am going zero miles per hour.

 

Interesting. I tried it today and it worked for me. Left foot on brake while stopped and right foot pressing on the gas and didn't experience any fuel cut off.

 

Yeah i know right? It sucks for me especially I regularly take my GS to the track. Brake torqueing my car would be lots of fun . Maby i have a revised version of smart stop.

 

Ding Ding Ding.

You guys are the best, def. saved me a trip to the dealer.

I am either able to hit the gas, or wait 3 seconds after the traction light appears.

Thanks!

 

Glad it worked out!

That's a feature I didn't realize it had until i'd had it for 2 years lol

 

Glad it worked out! Enjoy!
