Check Engine Light On problems of the 2002 Toyota Avalon

While driving home on 9/24/13 my check engine light came on, I drove right to the Toyota dealership. I was informed that the catalytic converter system was below threshold ( code p0420). This repair cost me $2,541. 27. I was told this would correct the problem with my air bag light flashing. After paying for this repair my air bag light continues to flash, even though the service representative said the diagnostic did not show a code. I was previously told the code for the air bag was b0113. Since purchasing this 2002 Avalon I have had to have the valve assy, idle replaced at a cost of 978. 63, this is in addition to regular scheduled services. I have owned other cars for the same length of time and miles as this Toyota and I have never had so many problems outside regular services with any of my other vehicles (Mazda and Acura) I have completely lost confidence in the Toyota brand. I believe there are defects with the electrical system in the 2002 Avalon.

I bought a used Toyota Avalon 2002 with @ 67k miles on it two months ago. I noticed that it occasionally had blue smoke coming out on cold start up. I took it to my local dealer for a regular oil change after 2,700 miles elapsed from when it was purchased. I did a carfax report on the vehicle prior to purchase and it showed that the vehicle was a one owner car with no repair or damage history before it was traded in. My wife drove it for @ 2,000 miles after the oil change when the engine oil light came on a few miles from our home. I checked the oil level and it didn't read anything on the dip stick. I was shocked when it took 4 1/2 quarts to read full. I immediately contacted the dealer (ehrlich Toyota, greeley, CO) that did my oil change and they scheduled an appointment today to assess the problem. I did some online research over the thanksgiving holiday about the problem prior to taking the car to the dealer. I discovered that Toyota has had significant problems with engine sludge that eventually causes sever damage to the affected engines. The dealer diagnosed this to be the problem with this car that I purchased on the 17th of September 2010. I discovered that Toyota came out with a csp (customer support program) to address this problem. In essence, Toyota agreed to perform any necessary repairs (including engine repair/overhaul) if the vehicle was identified with this problem and that the owner could prove regular oil changes had been done. This "one time" good faith fix applied to the affected vehicles for a period of 8 years plus 120 days after it's original purchase. I discovered that the original owner of my Avalon bought the car on the 24th of June 2002. That essentially makes my car out of the zone for this repair as of the 24th of October 2010. Because of this, the dealer said it's my problem! I can't tell you how furious this makes me that I'm now responsible for a defect I was never informed of at the purchase date of sept 17th 2010.
