Dont know what they would do to service the throttle body. Unless they need to get into that wiper assembly that is mounted to it. There is a procedure that is called 'Throttle Body Adjustment' that you can do in less than a couple of minutes. This is in the owners manual. Dont know if this will help you any but here it is. What it does is resets your ECU and it starts re-learning your driving habits . Good luck.

Throttle Body Adjustment. They say this works on all drive by wire vehicles and resets parameters WITHOUT Having to disconnect battery!


The Throttle is "Drive By Wire" and adapts to your particular driving
style. Do a TBA Throttle body adaptation.

1. Get in your car, it doesn't matter if you close the door or not.

2. Turn the key to the on (not start) position, the position just before the starter
turns over.

3. Press the gas pedal to the floor with the key in the "on" position.

4. Hold the pedal to the floor for five seconds, then turn the key back
to the "off" position (don't remove the key), then release the gas
pedal.

5. Wait 2 mins. for a full alignment.

6. Drive the car as you always do.

Depending on your driving style, this may or may not be a big factor. I do a lot of city driving so
I noticed a big change after erasing my history. It is not hard to do this, just follow the instructions -

Key on, pedal down, 5 sec, key off pedal up, wait 2 minutes.

Keep the key in for the entire thing.
