Toyota Highlander owners have reported 2 problems related to engine head gasket failure (under the engine and engine cooling category). The most recently reported issues are listed below. Also please check out the statistics and reliability analysis of Toyota Highlander based on all problems reported for the Highlander.
The engine overheated despite the no indication of high temperatures from the temperature gauge. We had it towed to the dealer who misdiagnosed it initially. We then drove it back from dealer (7 miles) to our home and it overheated again. Now the dealer says at a bare minimum the head gasket needs replacement ($3200) and it could new an entirely new engine. I don't know how this is possible at 86,000 miles. After doing some research I have found others with this problem especially 4 cylinders but it is not recall. Please help, I am unemployed and need this car!.
