I own a 2006 Toyota Highlander. Yesterday I took it in to have the oil changed with the usual inspections. Also got a new battery. When I got home three lights came on the dashboard, the TRAC, engine
light along with the VSC. I took it back to the dealer. They ran a scan and told me that a oxygen sensor
had failed and now needs to be replaced. Can this be a common problem and can I feel comfortable driving my SUV with these dashlights on? The technician told me that maybe the car wash that they offer us each time may have caused this problem. I do not buy his answer. What do you think? Is there any connection with getting a new battery and the sensor going bad?
JA: Have you checked the fuses? The dashboard bulbs?
Customer: No, I assumed the technicians did. What do you think I should do?
JA: Are you fixing your Highlander yourself? What have you tried so far?
Customer: No, I always take the SUV into the dealer for maintenance.
JA: Anything else you want the mechanic to know before I connect you?
Customer: No. Just some advice is much needed.
