2006 Toyota Avalon Owner Comments

  • 140,000 miles


Started car and smoke began pouring from the exhaust while stationary. Checked oil level and found to be within normal range. When driving, car was sluggish under acceleration with intermittent smoke. Took car to san marcos Toyota and they found the engine to be sludged and require an overhaul of the engine ($4900) or replacement of the engine ($6900). The vehicle had only 140,000 miles. We ended up having an independent mechanic overhaul/cleanup the top side of engine for $4000. I have the estimates and receipts for the work if needed. I have researched on-line and found many other Avalon owners who have had the same problem. I am filing this complaint in hope that Toyota will acknowledge the poor engineering of this V6 engine and issue a recall and reimburse their customers who have experience this engine failure.

When accelerating from a stop the vehicle will sometimes move about 10 feet and then hesitate for about 1 to 2 seconds. It will then accelerate normally. When driving in heavy conditions at speeds under 35 the car hesistates badly when you try to accelerate and then "jumps" forward. Same thing happens on the downside to the point that it feels like its going to stall. The service advisor also said there had been other complaints about this condition. This condition is dangerous and not normal.

Head gasket leaks both sides. Under repair. Poor design or manufacturing. Should not have occurred at this mileage level. My repair service indicated that this has happened on several Toyota products. Concern for accident potential should head gasket blow at high speed in heavy traffic where conditions do not allow for a safe exit from travel lanes to shoulder. Note: Vehicle registered under my wife maria's name.

The check engine light came on with the vsc and slip lights on the dash. Had it scanned and the codes are P2195 and P0138.

I am in shock given the today"S news. I was in an accident on 12/01/08 in my 2006 Toyota Avalon. I could not stop the car and ran into the T-bar of a box truck in front of me. My car was totaled. After the accident we called the Toyota experience center, they created a claim #1001145755 and erika with Toyota said they would be in contact with us. We next heard from a [xxx] with Toyota who then told us to mail our complaint to Toyota motor sales claims department in torrance, ca. We mailed of the necessary documentation from the accident and never heard back from them. We called back on many occasions all to be never answered or given a run around, once told they were looking into it. Nothing ever came of it all. We didn't know what to so we gave up, at the time we could not afford a lawyer. So today?S news was frustrating. Months prior to my accident we took the Avalon into dch Toyota of simi valley to check out acceleration problems. They said nothing was wrong with it and told me I needed a transmission fluid exchange and to have the power steering fluid flushed. We were told nothing was wrong; clearly there was. I am just curios what actions we take now. I am so frustrated and disappointed. Can you please advise me on what to do" information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

This cars engine had to be pulled out for head gaskets. I was charged $4000 when it was covered under the warranty. A year later they gave me the money back. Then I had external high pressure oil lines replaced and the gaskets several times. This car is one of the worst cars I have ever owned.I take care of my cars to the exstreme.I am a diesel specialist for the state.I finally had to get rid of the car.I wrote Toyota a letter and got absolutely no sympathy or understanding whatsoever.

On 03/22/2010 Toyota replaced a vvti oil hose under recall # 90K because the rubber portion of the hose was subject to failure that would cause the engine oil to spay out. On 07/24/2012 the replacement hose ruptured causing engine oil to spray out. The engine oil soaked the serpentine belt which is attached to the power steering pump as well as other components. This caused a loss of steering control which nearly caused an accident.
