    ok any clue what happened?
    my car was fine for past 3 months w/o any failure except dashboard light went off sometimes

    its old car w 250k mileage but i changed both 12v and hyb battery this year and as i said it went fine until today

    i changed engine oil and after that all possible warning signs (including red triangle of death) popped up and my car stopped in the kiddle of the road

    what could have been the issue?

    . the guy put wrong engine oil????

    when i towed it and brought it bck the guy deleted some data and reset it and it went just fine again... but i feel my car is little heavier than before (cant fully trust my senses tho)

    You should check the engine oil level, pull out the dipstick and check. If the guy put too much oil in, you would experience what you're feeling now

    Did the mechanic(?) record or write done the OBD2 codes (DTCs) before deleting them?

    Knowing the OBD2 codes (DTCs) may help in diagnosing vehicle troubles without wasting excess time or money.

    Can you clarify: a warning light, and if so can you remember which one, describe it? Or you mean that the dash display just went off, dark?

    Probably low oil pressure alert
    Ight flashing going around corners and the oil sump
    Pump going dry. Very very bad for your engine. Your oil is so low the dash light comes on. Quick way to ruin the engine.

    Your car has high miles and most likely eats a lot of engine oil. Are you capable of checking the engine oil yourself? Better start watching that dipstick
    Or you will be looking at a new engine.

    and if you went to a jiffy lube joint they over filled your oil so much it fouled the engine. Pretty common story. I found there Alldata database shows 5 quarts in a G2.

    A G2 engine holds little less than 4 quarts with new filter.

    I saw an 05 Prius with too much oil in it. It still ran but was sluggish. I guess it depends how overfilled it is.

    Underfilled would cause problems for sure.
