Bought Toyota Camry based on quality reputation.
We have 2001 Highlander also.
Begining there were recalls (leak above driver side visor let water in, gas pedal/accelerator/floor mat issue, VVT (sp?) hose, transmission slippage).
At 89K miles water pump broke. Dealer said it's $1,400 to replace as V6 models have major labor to remove engine parts to get at pump.
I had replaced Ols Intrigue that had same issue at 105K miles and was much cheaper to replace.
Will not buy Toyota again...will go with Honda Accord, Ford Fusion, or Hundai Sonata.
Very quite ride which was one of reasons I bought it.
Fix the bad quality.
2007 was new design year and it showed...lots of problems.
