Example complaints

“Vehicle began leaking coolant from the center of the engine. No warning lights or sensors have gone off period. Called Toyota dealership and manufacture line and both told me they have never heard of the problem, which is untrue I found hundreds of individuals with the same issue.”
NHTSA complaint #10497711, filed 2013-02, 205,205 miles“My trac off lights, engine and oil light came on when I was driving to work. I work far from home so I took it to the valvoline near my job to check the oil. I didn't want to drive my car home if there was no oil. They checked the oil, underneath my car and said everythingwas fine and to take to my mechanic to check the engine. I took it to my mechanic who kept it for 4 days and said its the oil sluge and he was trying to save the engine. My mechanic said they had a lexus in the week before with the same problem. …”
NHTSA complaint #10954090, filed 2017-02, 35 miles“Was driving on the highway about 60-65 MPH when engine began over heating. Pull over radiator was low. Put antifreeze in drove home check was allow again. The next called Toyota dealer, with out even looking they said you probably have a blown head gasket. But when we tear it down and if the head bolts are stripped out it will cost upwards of 2000.00. So now I have the car in an independent shop. I'm out almost 800.00 now, and the cars still not fixed. I believe Toyota knew about this problem long before I bought this car. …”
NHTSA complaint #10714728, filed 2015-05, 108,000 miles“My car began overheating at 140k miles. Took it to a mechanic and had the water pump and thermostat replaced. The car overheated again a week later. Took it back to the mechanic and he told me the head gasket was blown and had to be replaced. When he went to replace the gasket he found that three head bolts were stripped on the block. The cylinder head bolts separating from lower part of engine block caused a coolant leak. This is obviously a manufacturing error. This car was bought brand new and has been driven by the sole owner. …”
NHTSA complaint #10681355, filed 2015-02, 140,000 miles“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!”
