So I received the same "Service Electronic Throttle" error message last night on my new (1000 mikes) vehicle.
After several restarts the error message to service engine, and the engine warning light, have not cleared, though the vehicle seems to be performing normally (except the auto stop/start is disabled due to the error, and that warning shows up on the cluster as well).
When it happened last night, it was actually quite scary, as I was on the freeway. The car immediately lost throttle response and went into the previously mentioned 'limp mode'. That is, when I pressed on the gas the car actually lost speed, dropping to below 40mph, and declining. And it would not respond to stepping on the gas - essentially keeping the same speed or decreasing. I was able to pull of on the shoulder, and limp to an exit and park. I turned off the vehicle and restarted, and the error lights remained but the car performed normally (except the auto start / stop disabled).
Driving on the freeway without throttle response was a huge safety concern for me art the time.
I need to take the vehicle into Alfa to see what they say, and clear the code.
Edit: I admit I have sometimes driven with 2 feet. It's a throwback to my previous cars with clutches, so I guess I'm used to my left foot being active. I know, not good. I don't know if this was the case when I received the error code, especially as I was driving on the freeway.
