Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The vehicle was recalled due to faulty head gaskets, had them replaced by dealer in 1998 and at that time the dealer stated Toyota knew there was a problem with engine. The head gasket has again blown and I had to pay for this second repair from my own pocket. I want to know why Toyota, knowing the problem with the engine, won't repair it a second time...or if they will reimburse me the money I had to put out (1,300 dollars) for repairs and car rental.”

NHTSA complaint #751804, filed 2001-09

“Head gasket was replaced by dealer at no cost,but I also needed to repalce the timing belt according to the dealer. The drive train has a warranty for 60,000 miles,and I purchased an extended warranty for six years or 100,000 miles. You would think the timing belt should be replaced at no charge with a truck with such low mileage. My extra warranty was useless in this matter according to the dealer. If I didn't have it fixed they would say I didn't do proper maintance to the truck making my warranty void.I was in a catch 22 situation. …”

NHTSA complaint #701145, filed 1998-12

“Consumer called complaining about having problems with the antifreeze is leaking into the engine block and then is been pass into the exhaust system which consumer thinks is burning it and passing a white smoke that goes in to his house and giving him severe headaches. Dealer was contacted and stated that will only give him a certain amount of money and not be responsible of anything else if there is anything else wrong with the vehicle. Ts”
