Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2001 Mazda Millenia Owner Comments

problem #1

Dec 022010

Millenia P 2.5L

  • Automatic transmission
  • 102,000 miles


It's was nearing time for my emissions testing and just my luck, the check engine light on my 2001 Mazda Millenia P (2.5 engine) comes on. this time the catalytic converter. My mech told me that mine was fried and needed a new one. I always purchase my own parts, Always OEM and found a catco direct fit for about $250. they welded it on and tells me i need to put some data on the drive cycle for the emissions testing. As i get 25 miles into driving, the darn light comes back on, and of course its the catalytic converter again, these guys are stumped, i googled around and found out there is another converter directly underneath the engine, which is very pricey $500 and higher, could this one be the problem? is there a way to actually decipher which converter is the issue? PLEASE HELP!! my inspection expired 3 days ago, and i HAVE to drive my car to get to work everyday.
