warning light came on briefly, car stalled, had it towed to dealer. Water pump failed, caused engine to overheat to such an extent that the car needs new engine! Absolutely no warning. No indications of problems on any of the gauges- warning lights. No leaking. Car was driving fine. Have had many problems. Had extended warranty. Had to have a new transmission, several door locks replaced, computer chip replaced. A LEMON!!
