Question about 2003 Saturn VUE

2003 Saturn Vue V6 2WD catalytic converter problem

My Saturn recently lost a lot of power and when I took it to the Saturn dealer they told me that the catalytic converts where very clogged and needed replacing. They said that there were 3 of them, but I can only find one type when searching online for after market parts.

How many are there on this model and do you have any sites with a drawing or a recommended after market place to purchase them?

Also, can the converters be cleaned if they are clogged or do they have to be replaced?

    The price difference is huge. $2300 vs. about $1000 for the after market ones. Have you seen this yourself or know of someone that has tried the after market ones for a Vue? Thanks for the quick response and I would love to hear about your experience with these.

    I was just told the same thing I need to replace the Catalytic Converter for $846, do you think if I go to a muffler place it will be cheaper. I also own a piece of Junk they have done the transmission twice.

    You can not buy used converters, it is illegal.

I am sorry but the delaer is correct, there are 3, and the bad news is the after market cats won't work, the check engine light will come on if you use them and for that reason you will fail smog tests, the issue is how much they flow and the way they work is not compatable with the programming of the powertrain control module, stick with the factory cats, I know they are expensive but in the end you will have to buy them.

    There is a ceramic grid that is inside the converter shell, it breaks up and plugs the system, then the broken pieces get into the rest of the exhaust, did they check your muffler? in any event no they can't be cleaned or reused.

I'm currently dealing with the EXACT same issue with my 2003 Saturn VUE V6. While it was under warranty, I had numerous problems with my VUE (and still do) and Saturn replaced all 3 of them at their cost. (There is NO logical reason that a Single Exhaust V6 system needs 3 CC's. NONE!) Almost 2 years later, I'm having the EXACT same problem again, and now Saturn has gone under and won't honor the year left on my warranty. What a crock of ****! I'm not going to spend $1600 Labor ($$$) to have these USELESS things installed. For $1600 , I could put a down payment on a MUCH better vehicle from a company that actually backs it's warranties and isn't going to close a year or two from now, like Honda or Kia.

On your Saturn Vue V6.
Use 2 Catalytic One for Each Bank ( Head) Bank1 and Bank 2.
And one small Called in some places Ressonator.
some times is nessesary to replace all of them.

Ok.. Online you will find only one, Because they are the same for both sides.
I recomend take the car to a Muffler place.
They will have on stock, and you will have Warranty in all the Work.

They can clean the Catalytic But you will have the Check Engine light on. with the code P0430 and P0420, .
But go to the muffler place and take a second Advice with them.

I hope this help on your problem..
Thank you for use fixya....

Service vehicle soon like comes on after 25 minutes of running then it locks out my radio and causes the security light to also come on. I've had it on 3 different scopes & was told the codes were

I don't know who told you that , a semi- clogged catalytic will cause a low power issue an maybe a couple of DTC'S diagnostic trouble codes P0420 - P0430 ,Has nothing to do with the alarm system ! Do you mean Service vehicle soon or SERVICE ENGINE SOON ?
The IPC illuminates the SERVICE VEHICLE SOON indicator in the message center when the PCM or the BCM detects certain non-emissions related malfunctions. The IPC receives a class 2 message from the PCM or from the BCM requesting illumination. What problem are you having with alarm system ? If you have a starting issue it's the Anti-Theft system not alarm system . The alarm would go off if you vehicle was broke into . I don't know what shop you took it to but did you try a dealer ?

Saturn vue will start but will only stay runnuing about twenty minutes then stalls wont start

Does the car loose power before stalling or does it simply die without warning? If it loses power first, you're likely looking at a fuel pump or fuel system problem. If it just dies, you probably have an ignition problem. Does the check engine light come on before it dies?

I have no power taking off at stop lights when i use my ac and it seems to be using triple the gas(a quarter of a tank for 18 miles total) what are causing these?

Wow, that's a lot of gas. If your check engine light is on it needs to be scanned to determine the codes. I would check the catalytic converters to see if they are clogged up. A clogged cat will rob your power and cause poor economy.
