NHTSA complaint #10264909, filed 2009-04, 112,000 miles“Started burning oil at 58,000. Dealer replaced pistons and charged me $6376. Called mfg. To complain about cost. They immediately refunded 50% of bill. Was there a recall? Am I still paying more than I should? The 50% refund came too easy. I talked to a stranger at a car wash, with an identical car, who had the exact same problem! His was still under warranty.”
