well this morining i go to start up my gs..let is warm up alittle so then i drive off and bout 3 blocks i hear this noise..it sounds like that emergency broadcast test but much lower (thats the best way i could describe it) and it would last like a second then stop and bout 30secs later it would come back...it was very low though not really loud..then it stopp after like 10 mins

now heres the second thing that happend...this was bout 30 mins ago i was at a stop light just sitting had the radio on...then the car started to feel like it was gonna just stall out...it like shook alittle bit and had the stallin feeling but didnt stall out..no light or anything came on or nothing..drove the car home nice a easy and slow..didnt happen again though..does anyone know what this is?

i really dont feel like wasting my time with lexus since they dont listen to you anyway...thanks alot guys

 

nobody?? lol

 

Never happened to me , so i cant help . sorry

 

Tuddy, My car acted the same way like 2x at astoplight, never stalled but acted like it was going to. My conclusion was that it was being tempramentral (however u spell it). It never happened again, but then again I'd still like to know if other members had the same problem. It's so damn computer controlled that I say something is bound to go wrong at 1 time or another.Don't u run with a supercharger too?

 

If it makes you feel any better, I'm listening but dont know the answers. The only thing close to a beeping sound I've ever heard is when I'm cornering too fast and get the rear end loose the car starts to beep but intermittantly not constant.
Secondly, stalling is very common among Gs400's when u have the A/C off but I notice u have a 300 so

Anyways hope my reply consoled you somehow

HAHA i wish i had a SC..thanks for your response

it def was weird hopefully wont happen again

 

BTW, Ahmed inta min ay mantiqa?

 

You got PM , just so we dont hijack this thread

 

Sorry, I got u mixed up. Yes, gs400 i believe, have a few stalling issues but I'm not to sure about the 300"s. I don't think It's really to much of a problem, unless it happen's all the time, or at least more than often.

 

haha, Braheem, ana mish ahmad bes ana min jersey

 

Tuddy on number 2 it sounds like the "low idle" many GS4 owners experience. Do a search and you'll get lots of info including a couple of potential solutions.

What's probably causing this is that you're starting to run your GS without the AC turned on, which slightly increases the idle of your car. Turn it back on is one solution

 

I am curious of the noise that you heard... Have you checked your oil level recently?
