We just took are 04 Highlander in due to the wheels was making a noise and figured the brakes needed replaced and it sounded like the brakes warning noise. The veh has 76,000 miles and all the regular routine maintenance - the dealer ran the inspection and found major problems. Rear main engine seal leaking, water pump going bad and transmission seal is leaking. The cost for the engine seal and water pump is over $1,500 alone, wasn't given a price on the transmission problem. Of course, were over the warranty period. We contacted the Toyota warranty dept and waiting to hear back. Wanted to know if others have had the same problems and if there were any recalls.
