I can see many complaints similar to mine on line since the car was built in 2006. Driving on a 7hr trip when engine light came on and car overheated. We had to pull over on a busy highway and wait for car to cool down and light to go off. It was scary since I had my child in the car and traffic was moving at 60 mph. The next day I had the Toyota dealer charge me $160 to tell me coolant and oil were leaking from the head gasket and the bolt corroded and listed out causing a sealing issue. We just had the car in their shop doing thousands of dollars of maintenance and had a full inspection done in preparation for this trip. We also had fluid leaks from the engine twice before at 65819 miles and again at 84458 miles. No mention of this issue was ever brought up by dealer. I have full records and always did maint as suggested. so now the dealer says it will need a used engine at a cost of $9,000+. I am now without a car. This car should have been recalled and repaired, now it is totaled it. Thank goodness we were not injured or hit by another car on the interstate. sorry unable to send a copy of repair estimate done at Daytona Toyota 386-255-7475

Driving down the road at normal speed, I noticed the car overheating. This had never happened. Pulling into a 70 year old service center in cranston, Rhode Island, I left the car with reliable service people and they checked it out. It seems that the bolts had come loose from the engine and fluid was going into the pistons, they reported to me that the threads in the engine were faulty, I think they said aluminum, and they should have been metal. I am not mechanically inclined so I don't understand the whole problem. They said that the engine head was not secure and this has happened to other Toyota engines. Anyway, at 70 yrs old, it took all the money I had to repair it and they insisted that I look for a recall, because that should have never happened. $1842 later, the car is running like it should now. If Toyota doesn't take care of me, I will spend the rest of my life spreading the word. I will start at the Rhode Island dealers, go on line and contact all the proper areas. This should not have happened to my Toyota.this is the car that they advertise will last 265000 miles if maintained properly. I bought the car at earl stewart Toyota in lake park, Florida. [xxx] told me he was sorry that this happened, to report it to Toyota. My wife passed away and it moved back to my home state in Rhode Island. The car was maintained by Toyota always thru my warranty. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

When I was driving on the interstate about 75mph the temperature gauge rose above the read line (hot). Before I was able to get to a parking area it continuously rose and fell, however, it never dropped as low as the middle line on the gauge. After checking the fluids I had to add water. I took my Highlander to a mechanic and they told me that the intake manifold was cracked and was leaking coolant($700 to repair this). I had this fixed and had not taken it out of town until Apr 27, 2013 and the same thing happened again. Took it to Toyota and they told me that the threads were stripped and the bolts were coming out "the head is pulling away from the block and coolant is leaking. I take very good care of my vehicle and have every receipt for oil changes and maintenance. I was told that I may need a new engine ($6000 to fix this) and am concerned that this is happening to a lot of people with this type of car. Coolant is dangerous to humans, animals, and the environment so this can be a safety concern. Toyota needs to take responsibility for this error I am very frustrated and Toyota is not going to do anything about it. I know I am not the only one with this issue with this Toyota and they have lost a loyal customer over this. This issue is obviously happening more and more everyday and it is frustrating. Any advise is welcome!!!

While driving the temperature gauge rose above the read line (hot). Before I was able to get to a parking area it continuously rose and fell, however, it never dropped as low as the middle line on the gauge. After checking the fluids we had to add water. We took the Highlander and were told that it had a coolant leak. From there we took it to a Toyota dealership and were told that the entire engine would need replacing. I claimed that this had to be some sort of factory defect because he explained that the threads were stripped and the bolts were coming out "the head is pulling away from the block". we have always taken great care of our vehicle and this is not something that should happen to any well made vehicle. After doing research online I found that many others have suffered with the exact same issue and nothing was done to help with their situation. Please see the web page below. www.aboutautomobile.com/complaint/2006/Toyota/Highlander/engine+and+engine+cooling+system this is only one of several that I have found. While I am not sure if there are any safety issues here but many people have suffered when obviously Toyota is neglecting this issue. I'm not sure what else we can do but any advice would be helpful. Thank you.

I was advised that my head gasket blew at 80,000 miles and when they went to fix it they found the threads were stripped and I need a new engine? at 80,000 miles, this is insane. I googled this problem and found many people are having the same problem. There is obviously a manufacturers defect with these bolts. No way the threads should be strippled and a head gasket blown at 81,000.

High engine RPM at idle, the current mileage is 48,000.

Three months and 6000 miles past the warranty (66,000 miles) our Highlander failed (overheated). I googled the problem and there were many similar occurrences with this engine. Oolant leaked from engine onto floor in large amounts. Our mechanic said threads were stripped and three head gasket bolts had pulled out. Only solution, new engine or possible rebuild by Toyota dealership. Toyota refused to help us. They denied that this problem even existed. But why would Toyota put out a bulletin on how best to repair this problem, if the problem didn't even exist? Toyota dealership did not offer to help. We had our local dependable Toyota mechanic rebuild threads for $2,700.a lot of money to spend on a Toyota with under 70,000 miles. Very disappointed in Toyota's response. They not only lost my future business but also my daughter's. car works fine now. But I no longer have confidence in the vehicle. That loss of feeling of dependability is the worst part.
