| Description of the problem | I was driving to work on dallas north tollway cruising at normal highway speed. I was in 5th gear in the far left lane driving at consistent speed. I heard a pop sound and then a sound as if something were dragging. It was as if i had run over a block of styrofoam in a shopping cart. Immediately my car lost power followed by messages on the hud: low oil pressure; no oil pressure; see handbook. I immediately let my foot off the pedals and cruised to the shoulder. I saw oil or some other fluid had covered the rear of my car and was covering the ground underneath. The fluid had a reddish tinge to it. A piece of metal appeared to be hanging from underneath the car. Oil was everywhere. [xxx], the general manager of fiat of mckinney, told me that the engine needed to be replaced but that it would not be covered by the warranty because the maximum engine "over-rev" reached a value of 7300 a total of 26 times. Fiat vehicles are equipped with engine safety features which limit rpm to acceptable values. I have never reached that rpm in that vehicle. I received a copy of the fiat 500 diagnostics captured using a witech and it shows 3 pieces of data: total over rev counter = 26, max engine over rev rpm = 7320, total time exceeding max engine rpm 0. 0 seconds. There are no times associated with the overrev instances so that one could deduce that an overrev caused the engine failure. If it says that the total time over max engine rpm is 0. 0 seconds, how is this possible if it indicated 26 times? Since this is valued in total seconds, if the times added up to 0. 0444 - which would be the maximum value possible before rounding up to 0. 1, that means each of the 26 over rev instances would have lasted 0. 0017 seconds. Even if going at 7320 rpm, the fiat 500 engine can only go 12. 44 revolutions in 0. 0017 seconds. There is no way that it could be measured this accurately. |
