Dealers will inspect the crankshaft pulley and replace it if necessary.

2004 Toyota Highlander Reviews
Bought new Jan 2004. Just passed 190,000, and bought new Michelin tires so I expect at least another 90k, but want to get to 300,000. Still averaging 25.3 MPG with my 4 cylinder. Great vehicle, great service.
have 91000k on vehicle ,very reliable, gas mileage ok not great. The 4 cylinder is a little sluggish but overall a great suv .
Bought this vehicle new in February of 2004. Just turned 91500 miles. To date the only things replaced are headlights and battery. Decided to be proactive with the battery and test it before winter. Tested at half the amps so went ahead and replaced it.
Runs great and drives great. Look forward to another 91500 miles.
160,000 miles and no problems to report ever! Still on the original brake pads! Car handles like new. What a great vehicle. Expect it to last to 300,000 miles or more...
