Also, I stated to dealer that there was leakage surrounding the power steering pump. …”

“We bought a Toyota Avalon in 2005 for my son thinking that we have had a very good experience with our first Toyota. Yesterday, my worried son called to tell me that oil was leaking from his car. Not wanting to cause more damage to his car, he called a towing service and they took his car to the closest repair shop. There he was told that he had to take the car to a Toyota dealership as this problem has been reported by several Avalon owners. …”

“My 2005 Avalon with less that 40,000 miles -still under warranty -without any warning from dashboard lights began to lose power on the highway-then it shut down-I managed to get off the road and the car was on fire. Toyota had the car for over three months-could not tell what caused this but it melted just about everything under the hood. I was afraid to drive it but they would not make any adjustments toward replacing it. I had to call Toyota to get reimbursed for the towing. I had to demand a copy of the 10 page repair bill.”

“I have a 2005 Avalon xls with about 25,000 miles. I took it to have a routine oil change on january 23, 2009. When the service technician got under it to remove the filter and drain plug he noticed oil sprayed on the engine and frame and asked me if I knew the vehicle had an oil leak. I told him no and that I hadn't noticed any oil on the ground where I park the car. He then looked at the engine from the top and noticed oil pooling on top of a small hose that connects to a metal line. He told me I should take it to the dealer right away to have the oil leak fixed. …”
