| Description of the problem | The dash readout for mph began showing very erratic nmbers. Going from 24. 4 mpg to 29. 7 mpg and down to 13. 1 mpg all in a span of about 4 miles. This mpg of 24. 4 was for the prior 3000 miles. The dealer could not replicate this happening. They also said that toyota had no bulletins for this matter either. I contacted toyota and they said that i must have accidentally reset the unit and by doing so it was not unusual for these large swings in mpg. This was not the case. I had over 100 miles on since my last fill up and until this happening the mpg number was quite steady. The only that i indeed may have done this was that last fill up because that is the only time that i ever do a reset and i did not do it at that time. Previously i had seen some strange swings in mpg but not as large of a swing and not lasting for as long of time and those instances the reading did self correct. |
