My daughter’s 2000 Nissan Altima’s check light soon light came on. To cut to the chase, my mechanic said it was the oxygen sensor. He replaced it but the light still came on. He said it was the catalytic converter which was under warranty with Nissan. We brought the car to Nissan and after two attempts to shut the light they too agreed it was the catalytic converter.
They replaced it but now after two weeks the light came on again. Any ideas as to what is causing the problem? Should I bring to the car back to Nissan? I know that they will charge me again to have a diagnostic test done on the car. I am so tired of the runaround.
Please reply. Thanks.
The check engine light can come on for many reasons, the oxygen sensor and catalytic convert are two of them. I think I would take the car back to Nissan and tell them you just had the vehicle there for the “same reason” the check engine light. It could be something still stored in the onboard computer system that is causing the light to come on, or there could be a new problem, performing a diagnostic test is the first thing that should be done to determine which is the case.
I would not be mean about it, but I would definitely let the dealership know that they supposedly just repaired the converters in attempt to turn off the light. A little bit of pressure from your end might be just enough to get the problem taken care of without more expense on your end.
