Also please check out the statistics and reliability analysis of Toyota Highlander based on all problems reported for the Highlander.
Car temp gage went up past h and there was no heat in car. I stopped as soon as possible at a mall parking lot and called service. Had car towed to garage. Per owner of garage, the head gasket leaked due to bolts stripping in the engine. He then fixed the problem and then upon test drive the tensioner failed and chain jumped causing further repairs to not be cost effective. Through research he informed me that this is a well documented problem with the 2003 Highlander engines and that Toyota is not backing the problem. I called Toyota and since recall has not been issued they stated they cannot help me. I feel the Highlander should have lasted more than 8 years as I had kept up with required maintenance.
