Making Noise And Delayed Start When Ignition Button Pressed

[nanasauntie]

So the other day my 07' IS250 started making a rattling/gurgling noise right as the car started. Now my Husband says it acted like it didn't want to start and made a clicking sound. Now way this could be the starter? Any ideas?

If it's turning over slowly or just clicking the battery is low.

My 2007 IS250 RWD is having a similar issue.

With the engine hot or cold, AC on or off, I get the following symptom:

Normal Start Sequence

Depress brake.

Depress starter button.

Engine cranks.

Engine fires.

Something gives a single audible "click" as the engine spools to idle.

Sounds like CHU CHU CHU VrooOOOO (CLICK) oooom

Occasional Faulty Start Sequence

Depress brake.

Depress starter button.

Engine cranks.

Engine fires.

Something gives a repeated audible "click" (about as fast as I can make my tongue "motorboat" against the roof of my mouth) as the engine spools to idle.

Sounds like CHU CHU CHU VrooOOOO (CLICK.CLICK.CLICK.CLICK.CLICK.CLICK) oooom

Had it into the dealer yesterday, but we tried it, together about 20 times, both hot and cold, and the fault didn't happen once. Then, predictably, I went to run errands and it happened on the next start.

I'm thinking the starter is having trouble disengaging, but have no way to tell.
