The dealer told us the O2 sensor was bad. It fixed the problem for about a week. Light came back on and they said it was a different sensor. Asked them how many O2 sensors the Veracruz had and they said 4. We are 3 sensors in and the light has come on again. Does any one know how many O2 sensors a Veracruz really has?
