Vehicle began slipping out of gear between 1st & 2nd, then started losing power at 74,760 miles. Extended service coverage has been issued for model for CVT transmission pulley system, however only covers 10 years or 100,000 miles, whichever comes first. Mine apparently timed out in February, so they are trying to make me get a new transmission which basically totals out the car I spent a fortune on to buy & in repairs at under 75,000 miles. This is unacceptable.
