12/05 catalytic convertor put in toyota carolla {light was on]. I have returned many times again because the light was on and either told there was nothing wrong or they changed the convertor x 2. 7/2 i returned, light on and now mechanic wants to put toyota convertor in and apply my money from 12/5. He admits he used after market parts previously. A toyota convertor done by toyota would cost over a 1000 and would have a warranty for life of the car whereas if he put it in the warranty runs out in a year. He refuses to return money and refuses to turn off the light. I honestly do not know what he has done in the past because when a receipt was requested it was blank as to service. These are accredited mechanics. Last, they give you a loaner for 5 dollars, but the last car was older than mine, had less miles by 70, 000 and isn't it illegal not to have the mileage work? I needed that for home health mileage.
