Problems with 2006 Toyota Highlander ENGINE AND ENGINE COOLING

Tl* the contact owns a 2006 toyota highlander. while driving approximately 15 mph, the temperature gauge increased. in addition, the traction, check engine, and vhc warning indicators illuminated. an independent mechanic stated that coolant fluid was leaking and an engine kit needed to be installed. the vehicle was not repaired. the manufacturer was aware of the issue. the vin was unavailable. the approximate failure mileage was 130,000.

Coolant leaked from engine onto floor in large amounts. our mechanic said threads were stripped and head gasket bolts had pulled out. only solution, new engine or possible rebuild by toyota dealership. we were under 60,000 mile warranty but over 60 months. toyota refused to help us. sadly i've been changing my own oil and didn't keep all receipts for a maintenance record. lesson learned. toyota dealership offered new engine for $7,300 or rebuild for $4,600. we had non-toyota mechanic rebuild threads for $2,300. car works fine now. way more money than we expected to spend on a toyota with under 60,000 miles. *tr

I purchased a used 2006 toyota highlander from a fernelius dealership in michigan in april 2011 - it was in mint condition with 56210 miles on it - thought i had made the best deal ever - then the day before thanksgiving while driving it overheated. thought i had blown a head gasket only to find out that the thread bolts on the short block had stripped out and leaked radiator fluid everywhere causing it to overheat. at that time the mechanic told me that i needed a new engine. contacted the dealership and they told me too bad i bought a used vehicle if i wanted to tow it to them they would look at it. i than contacted toyota corporation only to be told pretty much the same thing, since i wasn't the original owner they weren't going to help me either. so now i'm stuck trying to find an engine because the dealership can only offer me one with 58000 miles on it installed for about $7,000, and from what i'm reading on the internet they have this problem when the engine reaches right out of the warranty at 60,000 miles. ...

I was driving in my highlander with my daughters in the back seat when suddenly out of no where all the alert lights came on and there was no power at all - the gas pedal was non functional - i was in the far left lane of a an interstate and fortunately i was able to get off the road and pull the car out of traffic as it rolled to a stop. i waited on the crowded interstate for two hours for a tow. i was told that the highlander hybrid inverter had failed - the dealer replaced the part that week and the car drives normally now. i was advised that in fact this is a known problem. one month later ironically i received in the mail notice from toyota that my model of highlander is being recalled for the inverter replacement that had just caused this extremely unsafe vehicle failure just one month prior. *tr

My wife was driving our 2006 toyota highlander. she drove approx 1/2 mile from our house at an average speed of 35 mph when the temperature gauge suddenly went past the red line. we had our car towed to crown toyota where they tore down the engine and found water pump leaking and head gasket leaking oil . they removed engine head and found warped block and but head was okay. we then towed the highlander to a private mechanic to have block replaced and we were informed the block was not warped but instead the bolts on the engine are stripped/defected. toyota wants $5,400 to repair vehicle by installing a used engine. toyota refuses to help with the cost even though it appears to be a manufacture defect and has already charged us $654 to diagnosis the problem and did not even reassemble our engine. the car was no longer under warranty at 68,970 miles. we have not yet repaired the problem. *tr

My son was driving our 2006 toyota highlander. he drove approx 2 miles from our house at an average speed of 35 mph when the temperature gauge suddenly went past the red line. he drove our car approx 2 miles back to our house. we then had it towed to savannah toyota where they checked the engine and found the head warped and the bolts stripped . i went to savannah toyota and told them that i had just had the car there for an oil change a month prior. at the time of oil change, service writer noted under the hood that he thought that maybe the water pump may be leaking as there was fluid on the upper part of hood. there was no notification of any problem with the water pump. a month later, the above overheat condition occurred. when we were informed that the engine was burned up and the engine needed to be replaced at a cost of 5000.00. we had the vehicle towed to our regular mechanic and was told that there was nothing wrong with the engine block, just the head needs to be replaced at a cost of approx. 2200.00.savannah ...
