Q: Emissions Fail on 2005 Chevrolet Malibu

My friend took their Malibu in to get the emissions test and it ended up failing. After taking it to a trusted personal mechanic and also an emissions specialist mechanic they couldn't figure out what the problem was. It's suggested that it might be the catalytic converter but after looking into some forums it appears this is a problem with this model and an expensive catalytic converter replacement might not even be enough to make the car pass emissions.

The emissions department is unwilling to give any kind of extension on this. What can my friend do in this situation?

I cannot find any technical service bulletins releating to failing a smog check for the Chevrolet Malibu. There have been some cases over the years where different models for one reason or another have had problems passing the state emission tests. I find it hard to beleive that a 2005 model would have such a problem. This may be worth a trip to the dealer. There are some emission releated components the have extended warranties. In addtion, if the dealership technicians cannot figure out the problem they can call GM for help. Bring all the information you can if you go to the dealer - the printout from the failed smog check and any information you have from the online forums.
