1. We bought Toyota Sienna 2007 le #3 on July 21, 2007 2. After 2 weeks on Aug 4 2007 maintenance required and all other lights were on and ac was stopped working. We called the dealer and he scheduled earliest appointment on August 7 2007. 3. On August 6 2007 Toyota Sienna broke down on interstate and I towed this van to the dealer. 4. Dealer first found problem with the alternator and replaced alternator in a week. 5. Then he found another problem as two computer inside car were not functioning properly and he worked with Toyota specialists and order replacements of computer harness equipment. 6. After installing these new equipment he found that all the lights on the dash board are turned on with this vehicle. 7. He scheduled inspection to resolve this issue by Toyota technicians. They are flying in from California to resolve this.
