My xB makes a hurring sound as if you placed your tongue on your palate and make it vibrate. This happens when the car gets above 25 mph.
My scion make this noise like hurring verses a grinding or whurring sound. It happens above 25 MPH and above. The auto shop checked the car out but can not positvely tell me if the rear bearing is the culprit. On the rack, they turned the wheels and monitored with a stetiscope and are not able to pick up any bearing noises that are normally present when bearing are about to go out. The noise is a little less when I am making a left banking turn. Sound started with low noise 5 days after front tires were changed. Garage ruled out CV system, Wheel alignment. Best guess was rear left bearing. According to parts supplier bearing/hub assembly is about $500.00 USD not counting special order charge on a best guess.
The car has 75,000 miles on it, is not driven abusively. Seldom do I have to go over 60 MPH. Average daily speed is about 35 to 45 MPH. Oil changes are not always on time...I do have engine sludge removed from oil pan when engine is flushed if I fail to change on time ( 10K to 12K miles from last oil change.

Just athought, have you used the same tyres on the front, or are they a different brand. Virtually impossible to determine if you have a wheel bearing problem over the net, I would take the best advice you can get from people that have taken it for a drive.

I know you are looking to have the remote starter run a third time but I would say you need to look at your Fuel Pressure Regulator on the Scion. Sounds like it is not holding fuel pressure at the fuel rail and that is why it requires a third Crank
my scion xb is at the dealership right now because i heard the same noise coming from the rear tires, i was told today that both my rear wheel bearings were bad and have to replace them, $300 plus each for the part alone, $500 for with labor.
3500 is about normal for an xb at 65 mph. My previous ride was a pickup and rolled at about 2000-2500 on the highway. But the XB's engine is way more "tightly wound". Your rpm gage should run at about half of of your speed...ie: 70 mph will be about 35 (3500) rpm, 80 mph will be about 40 (4000) rpm. Freaked me out when I first got the thing, but after researching it Ive found out that with a stock engine it actually runs more efficient at the higher RPM's. The 06 boxes won't redline until 6000 rpm, so unless you are driving 120 on a frequent basis you're good. You can probably have it modified to run lower, but you will lose the awesome gas mileage and overall it is not going to improve the way it runs, and would have no benefit............
I had that issue with my scion xb. When I installed my audio system somehow the vibrations loosened the button wires clip . I removed the door panel and clicked it back in, also it could be a dead solenoid or disconnected door wire that goes from the 'noid to the door lock pin.
