Fuel Delivery Problems of Toyota Avalon

Went to Toyota dealer to diagnose/repair check engine light. Call from dealer reported air/fuel sensor defective -- gave price of $449 to repair, dealer was authorized to proceed. Two hours later, another call from dealer reported that sensor could not be removed (frozen or "welded" in place), would have to replace complete manifold at cost of greater than $1000. I believe this should be Toyota's responsibility due to faulty assembly. (see previous report of insufficient anti-seize compound used. ) unless adequate compensation is forthcoming, I will continue to drive the vehicle this way, as I am told it will not do damage to the vehicle, but only affect gas mileage. However, as this is part of the vehicle emission control system, I suppose it will be further damaging air quality.

The contact owns a 2000 Toyota Avalon. The contact stated that the air fuel sensor failed. While the vehicle was being repaired, the mechanic damaged the manifold because the vehicle lacked anti-seize compound. The check engine and abs lights illuminated during both occurrences. The mechanic informed the contact that both the 1999 and 2000 models lacked sufficient anti-seize compound to prevent the damage. There are three sensors that may fail and the contact is concerned that the manifold will need to be replaced after each failure. The mechanic explained that the failure has been corrected in subsequent model years. The contact felt that she should not have to pay for the manufacturer defect. The current and failure mileages were 62,000.

I own a 2005 Avalon that has a transmission/throttle problem. Slowing from speeds in excess of 30 mph, then accelerating moderately, the engine will increase rpm to 2500-3000 rpm and the transmission will shift into neutral until the electronic control decides to shift to a lower gear. At the shift point the car will surge forward rapidly. This surge occurs even on this vehicle with traction control. This "surge" has resulted in multiple near end collisions in city traffic. The neutral shift problem has also been encountered on occasion when entering high speed interstate traffic. 18 wheelers bearing down on you at speed while your car is turning 4000 plus rpms in neutral is frightening. The vehicle has been to three separate dealers and a complaint was registered with Toyota manufacturer. Toyota responded, saying the transmission was operating as designed. Hopefully someone will correct this problem before I, and others, become a statistic in a class action suit as an injury or death numbers. Many complaints on this problem can be found on several other web sites. I've been a Toyota owner for over 25 years and this lack of response by the manufacturer on this high end of the brand ends that . And Toyota does not care if they lost a long term customer, so stated by Toyota of America.
