2004 Toyota Sienna Owner Comments

problem #2

Jan 012006

Sienna 6-cyl

  • 28,000 miles


I bought 2004 Toyota Sienna minivan in Dec. 2005 as a used vehicle with 28,000 mile and manufacturers warranty still in effect. Right from day one we noticed that navigation system that costs nearly $2,000 didn't work as expected. It tends go off course by several and sometimes by as much 30-40 mile off course. We took it to two different Toyota dealers at least 5 times. Every time when we bring the car to dealer their first response is that there is nothing wrong with the car, but with further prodding they have put new software and changed gps receiver (antenna), but the navigation system, even though better than before, still gets off course by miles. My wife who drives the car most off the time is afraid to get lost in some bad section of city of phoenix, AZ. We have not been able to get proper repair or replacement of the system as should have been done a long time ago. We have had the with alexander's Toyota once for almost one month and it still has not been fixed.
