We purchased this car new and kept it dealer maintained for 7 years. I found it to be quite a reliable vehicle until recently. At 118,000 miles it developed a coolant leak. It was ultimately found to be due to stripped out threads in the engine block (i.e. the car needed a new engine ~ $7500.00). After discovering that I was not the only one to experience this problem (check online Toyota forums), I notified Toyota. The Rep stated, "Your engine may be defective, but we cannot help you because you are out of warranty." Beware of the 4 cylinder engine in the 03 Highlander! A dealer maintained vehicle is worthless, and Toyota has lost a customer. And so it goes.
