Of course, many people encountered it. You need to see what codes are stored in your system.
You can get a bt OBD2 scanner like this one or, since you are the lucky owner of the first gen 2 tech model, you can go into the service menu and check out the diagnostics: after starting the car wait for the "OK" message to pop up on the screen, click OK and then Hold the Map/Guide, Cancel and Menu buttons for about 3-5 seconds for the service menu to appear. From there go to the second option (ECU) and then choose the Acura Diagnostic Info. You should see all of the errors stored there. They should stay there even if the error went away by itself, unless you manually remove them from there.
