I have no Idea what make or model your car is, However my first guess would be a power steering pump being low of fluid.

Some alternators will complain during higher output to replace the charge you used in starting the car.
An old mechanics trick is to use a screw driver, held with the handle pressed firmly behind your ear (bone conduction) and then press the tip on various (NON-rotating!!) accessories to isolate the source of the noise.
An old mechanic friend could tell you exactly which bearing, crank or rod, was rattling and predict how long you had before failure.

I have the same problem like yours but what i did is to replace the alternator and now its so quite no more high pitched sound. You may used belt stress fluid but its only last for few seconds then sound comes again. I replaced it with refurbish part alternator.My sienna 2005.

Check your brake pads first,as they have a wear warning clip on them.so if you hear a loud screaming noise.Then its quite possible they have worn causing ur warning lights to come on.And i would get anouther quote as that is quite dear for a pump replacement.If it is the pump.good luck pippall!!

you could be low on transmission fluid check that and make sure it registering properly on the dipstick.

Have the tranny serviced with fluid change and filter, if noise it still there it is the torque converter . Have the dealer fix it ,and have it on paper with dealer invoice when it is done. Do all this before warranty expires. IT IS NOT USUAL for any car, Toyota included, to have tranny whine!!!!!
Hello
The
Engine and Automatic Transmission (not applicable to manual
transmissions) in this vehicles drive train are fully electronically
controlled by a computer called the PCM and TCM (Power Train Control
Module, Transmission Control Module). When a problem like this or
other drive-ability related problems occurs the computer stores a
record of the problem (there are of course some exceptions to this,
like the fuel pump, engine coolant temperature sensor and MAF sensor
for instance) in the form of a fault code in its memory, to read
these fault codes you must have the systems memory scanned with a
special tool. Once the fault code(s) are read you then must perform
the appropriate diagnostic testing to find and resolve the problem(s)
DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED
THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT
MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for
correct spec for your make and engine type.
